Professor Panduka Karunanayake of the Faculty of Medicine, Colombo has issued a very welcome book: mostly a collection of essays and notes he wrote to newspapers and two public lectures. They cover huge areas of social policy and therefore are very likely to give rise to public debate, all very welcome.

Panduka (if he will pardon me) belongs in a tradition of medical personnel who have interested themselves in problems in this society, well beyond health and medical care. Gunadasa Amarasekera, a dental surgeon, is the grand master of them all. He contributed innovation in Sinhala fiction and poetry and more recently has been very articulate about public policy on a large number of issues. Carlo Fonseka was a superb academic leader, a fine teacher of Physiology, a public intellectual of the first order who was a member of the LSSP all his adult life, a rationalist who did much to dispel superstition, a lyricist, a connoisseur and patron of the arts and a debater par excellence in print. S.N. Arsecularatne, a distinguished member of the Peradeniya Faculty who cultivated many interests, addressed a narrower audience on the growth of knowledge. Susirith Mendis, another highly distinguished teacher of Physiology, brought new perspectives to bear on whatever social phenomena he examined. N.A.de S. Amaratunge, an outstanding oral surgeon, has taken up many issues. More recently, Upul Wijayawardhana an eminent cardiologist, Sarath Gamini de Silva an eminent physician and B.J.C Perera a distinguished paediatrician have begun to comment on features in our society. Occasionally A.H. Sheriffdeen, an eminent surgeon, also contributed. Panduka Karunanayake joins that brilliant galaxy not too far away from earth, that has shed much light on murky areas in our society. His main area is education, especially university education. Sarasvati is the goddess of knowledge in the Hindu pantheon, and some of us prefer to signify a university in Sinhala as sarasaviya.

I have lived through the entire process which Panduka writes about. I was educated with taxpayers’ money, all the way. They were central schools for a long time. (Central college is a foolish affectation, following the names of the denominational schools that copied the nomenclature from Public Schools in England.) The most valuable assets of central schools were their teachers, especially principals. From Sumanasuriya in Wanduramba, Devendra in Hikkaduwa, Jayasuriya in Matugama, Jayatilleke in Ibbagamuva, Eratna in Anuradhapura to Ekanayake and Wilmot de Silva in Pelmadulla, they showed a commitment, enterprise and initiative that now seem impossible. (Old-timers still reminisce Jayatilleke together with parents clearing the jungle in the school yard.) They in turn collected staff of teachers that now seem to have come from another world.

Apart from outstanding teachers, central schools in those early years had little to commend themselves. Choices were limited: no Mathematics, no Science, no Pali, no Sanskrt, no Greek, no Latin and many others. W.A.de Silva, the Director of Education, reported that in 1948, 17,000 persons applied for positions as English teachers but not even 1,700 were found competent. That rueful trend continues to date. Facilities were woefully limited: no libraries, no laboratories and no playgrounds. Yet those principals, teachers and students worked wonders. Parents were too ill-informed to instruct either their offspring or, of course, teachers.

It is good to recall that teachers, especially in the English medium, were then paid about four times the GDP per capita. The foolish policy of governments to pay teachers no higher than the average per capita income as now has destroyed the elan of the corpus of principals and teachers. That is a consequence of the massification of secondary education that has cost us dearly, which Panduka speaks of. Costs of inevitable massification have to be counted when one sings of its benefits.

It is useful to recall that secondary education was massified in the US around 1900, after its economy became the leading economy in the world. If you compare internationally, countries that pay their schoolteachers decent wages (Finland, Sweden, Denmark and France) have excellent school systems. High wages paid to schoolteachers in Africa are scarcity rent and will be whittled away in time. Secondary school systems in the US too have been destroyed by low wages paid to teachers.

The nature of secondary and university education has undergone much change all over the world during the last 50 years. And the essential quality of such education is flexibility rather than fixity for long. If you read the advertisements put out by tuition masters selling their skills on television now, you will be struck by the wide spectrum of vocational courses that children follow from grade 10 to 13 in school – the last four years in school. They expect to be selected to universities for the study of these courses and to pursue careers in them. These courses are very different from what bright students went through a mere 50 years back, when my age cohort left university. To mourn over a system of education that one benefited from but is now shunned by students and parents alike is futile. The ideals espoused by Cardinal Newman and admired for long have had to be discarded in the midst of rapidly changing economic factors. Universities are more the handmaidens of industry than ever. This book invites the reader to debate these questions rather than accept dicta laid down by men in power but with little authority.

Panduka presses the policies he talks about through three sieves: equality of opportunity, equality of outcome and quality of outcome. He is also concerned with whether education is provided by the public or the private sector and with university freedoms. He explores, to some distance, the function of universities in society. However, the book is organized on different axis (especially his attempt at periodization), making the task of a reviewer that much harder and I will lose some valuable insights he develops.

Let us take the Kannangara reforms as an effort at promoting equality of opportunities. Compared to what prevailed prior to that, it was a distinctly successful attempt to greater equality of opportunity. In 1974 I published a paper comparing the economic and social background of university entrants in 1967-68 with those in 1950 (Strauss). The effect of Kannangara reforms in spreading opportunities to enter university were much in evidence in 1967-68.

It is important to keep in mind that their effects were compounded with the change in the medium of instruction into Sinhala/Tamil. The latter was far more powerful than the reforms. Sometime in 1967, I went with G.P. Malalasekera, then Chairman of the National Council of Education, to discuss with Minister Iriyagolla the problems that arose with teaching in Sinhala in universities. When the question of admission of students who had little knowledge of English came up, the inister was quite straightforward: “I cannot go to Meegahakotuva and tell the people there that their children who had been taught for 12 years in Sinhala, in government schools, now could not go to university unless they had a knowledge of English”.

At the same time, the rising proportion of a larger number of children in an increasing population compounded the problems of providing good university education.

Government had been heedless, and neglected thinking about these problems and considered the creation of two new universities sufficient to solve the problems. (Jennings did not see that what he accomplished in Peradeniya was utterly inadequate to meet with the demographic changes that were manifestly evident at the 1946 Census and the 1952 Census.) Some academics, in their zeal for the promotion of indigenous languages, also misled the politicians.

The consequences were a fall in the quality of education, especially in social studies and languages. Mathematics and Science could muddle through. Engineering and Medicine continued regardless. Good university teachers do not come about with the same speed as governments change their policies, and the scarcity of competent teachers stood in the way of providing high quality education. The present government with ambitious programmes for expanding university education had better look sharp. There was a clash with the ideals of promoting equality of opportunities and the maintaining of high quality university education.

Recent research has made it abundantly clear that whatever the positive steps that governments take to reduce inequality in opportunities, family culture plays a major part in the outcome. The outstanding evidence in Lanka is the scarcity of entrants to universities from homes of people who work in tea plantations and live in ‘lines’. In Allahabad, in a faculty strength of 112 teachers, 76% were Brahmin and Kayastha, when their proportion in the total population of Uttar Pradesh was 20%. In US, SAT scores are persistently in this order of excellence from the least to the highest: Blacks, Latinos, Whites and Asians. It is shocking to most people that Black people who have for generations lived as free men in that country continue to stand disadvantaged in the ladder of scores in test scores. The explanation is mostly in the poverty of home culture, as is the case in India, where the relevant categories are Dalits and Brahmins and others superior castes.

In Sri Lanka in 2019, of some 10,000 government schools, only 1,000 were classified as 1AB schools and had classes teaching up to grade 13 with facilities for teaching Science and Technology. In contrast, there were 1,900 1C schools teaching up to Grade 13 in Arts and Commerce. In the rest, or 2 out of every 3 schools, there were no facilities for teaching beyond Grade 11. In contrast, 2 out of every 3 teachers were in the other one-third of schools (1AB+1C). Inequalities in opportunities are written into the structure of schools. It is not the preferences of parents and students that sends hoards of students to study languages and social studies. Governments have programmed supply lines to do so. No amount of fidgeting at the apex will modify that foundation of the pyramid.

Private tuition follows roughly the same pattern. Private tuition, on which Panduka comments, is not something peculiar to Sri Lanka. In Britain, in 2019, 25% of children aged 11-16 years received some kind of private teaching outside schools. In China, parents spent over $10,000 per term to coach children for the university entrance examination; New Oriental and TAL Education are two of the biggest education companies in China. From Juku in Japan to large corporations in California, it is common flora in the jungle of these plants. In China, ‘princes’ (offspring of the privileged) end up learning in Ivy League colleges, with children of common people unable to send their offspring to a city school in China, because they do not have a hou kou to live in that neighbourhood. Finding solutions to problem of substantially reducing inequality in opportunities for higher education is going to be a hard nut to crack.

I will comment, even if briefly, on the problems in dealing with political interference in education. With government paying for all university education, it is inevitable that there will be political interference with matters of university education. All state, city and community colleges and universities in the US are maintained mostly with government funds. Most great universities in Germany and France are owned and paid for by the state. There have been many reports on the abuse of power over universities by States in India.

Governments do interfere in university life, but whether such intervention is beneficial or not depends on the degree of enlightenment among those running government. Recall the great Wilhelm von Humboldt of Prussia and Mori Arinori of Japan – both ministers of government and founders of great universities. Learning and reading that do not run beyond a capacity to read a teleprompter is not likely to be sufficient to nurse universities to excellence. While governments ambitiously interfere in running universities, their incapacity to eliminate rapacious ragging in our universities is outrageous.

There is another kind of interference in the work of universities: obstructing independent inquiry. Such interference comes from both governments and large corporations who determine the programmes of research which they espouse. We know from experience that knowledge grows best when exposed to free examination. Consequently, all measures taken by governments to curb free inquiry in universities are to be deplored as unhealthy.

I have exhausted my ration of words to review Professor Karunanayake’s book. Yet there are three other main issues that he explores which I have not touched: employability of the output of the system, the functioning of a parallel private sector in education and the clash of elites’ interests.

Professor Karunanayake’s arguments are sound and fortuitously timely. The Minister of Education announced some time back that the government would reconsider the entire design and content of education. It is your function to contribute to those mighty tasks. Professor Karunanayake’s book helps.

Gotabaya’s escape from Aragalaya mob in RTI spotlight

Published

Sahan Weerasooriya

Crowds throng Janandhipathi Mandiraya after President Gotabaya Rajapaksa vacated the building on 9 July , 2022.

The Court of Appeal declared on 09 March, 2026: “On the facts currently before us, the application of the exemption contained in Section 5 (1) (b) (i) of the Act is unsustainable. There is a little logical connection between the requested statistics in this information request (that do not pertain to the personal details of individuals) and national security. We see that asserting that national security is at peril, is not a “blanket or unreviewable justification” for withholding information. It should be noted that any restriction must be strictly necessary, proportionate, and supported by a “demonstrable risk of serious harm to the State.” In the case in hand, the Petitioner failed to establish a clear nexus between the disclosure of naval voyage expenditures and any genuine prejudice to national security under Section 5(1)(a) of the Right to Information Act. In the absence of specific evidence, the reliance on security is characterised as a “generalised assertion or mere assertion” cannot be a panacea, we hold it is insufficient to meet the statutory threshold.”

By Shamindra Ferdinando

The deployment of SLNS Gajabahu (P 626), an Advanced Offshore Patrol Vessel (AOPV), on the afternoon of 09 July, 2022, to move the then President Gotabaya Rajapaksa, being pursued by a violent aragalaya mob, to safety, from Colombo to Trincomalee, is in the news again.

The issue at hand is how much the deployment of the vessel cost the taxpayer. In response to the Right to Information (RTI) query, the Navy has declined to reveal the cost of the AOPV deployment, or those who were given safe passage to Trincomalee, on the basis of national security.

SLNS Gajabahu, formerly USCGC Sherman (WHEC-720), a United States Coast Guard Hamilton-class high endurance cutter, was transferred to the Sri Lanka Navy on 27 August, 2018, at Honolulu. The vessel was recommissioned 06 June, 2019, as SLNS Gajabahu (P626) during Maithripala Sirisena’s tenure as the President. (Last week, US Special Envoy for South and Central Asia, Sergio Gor, who was here to deliver a message to President Anura Kumara Dissanayake, in the company of Navy Chief of Staff Rear Admiral Damian Fernando, visited SLNS Gajabahu, at the Colombo port.)

What would have happened if the then Navy Chief, Vice Admiral Nishantha Ulugetenne (15 July, 2020, to 18 December, 2022) failed to swiftly respond to the threat on the President? Those who spearheaded the violent campaign may not have expected the President to flee Janadhipathi Mandiraya, as protestors breached its main gates, or believed the Navy would intervene amidst total collapse of the ‘ground defences.’ Ulugetenne accompanied the President to Trincomalee. Among the group were the then Brigadiers Mahinda Ranasinghe and Madura Wickramaratne (incumbent Commanding Officer of the Commando Regiment) as well as the President’s doctor.

The circumstances leading to the President and First Lady Ayoma Rajapaksa boarding SLNS Gajabahu should be examined taking into consideration (1) the killing of SLPP lawmaker Amarakeerthi Atukorale and his police bodyguard Jayantha Gunawardena by an Aragalaya mob, at Nittambuwa, on the afternoon of 09 May, 2022 (2) the Army, deployed to protect Janadhipathi Mandiraya, quite rightly refrained from firing at the violent mob (3) efforts made by the top Aragalaya leadership to compel the then Premier Ranil Wickremesinghe to quit. Subsequently, it emerged that pressure was brought on the President to remove Wickremesinghe to pave the way for Speaker Mahinda Yapa Abeywardena to become the President and lastly (4) arrest of Kegalle SSP K.B. Keerthirathna and three police constables over the killing of a protester at Rambukkana on 19 April, 2022. The police alleged that they opened fire to prevent a violent mob from setting a petrol bowser, barricaded across the railway line there, ablaze.

Now, swift action taken by the Navy, under extraordinary circumstances to prevent possible threat on the lives of the President and the First Lady, had been challenged. The writer felt the need to examine the evacuation of the President against the backdrop of an attempt to compare it with President Wickremesinghe’s visit to the University of Wolverhampton in September, 2023, to attend the awarding of an honorary professorship to his wife Prof. Maithri Wickremesinghe.

The 09 July intervention made by the Navy cannot be, in any way, compared with the public funds spent on any other President. It would be pertinent to mention that the President, fleeing Janadhipathi Mandiraya, and the withdrawal of the armed forces deployed there, happened almost simultaneously. Once a collective decision was made to vacate Janadhipathi Mandiraya, they didn’t have any other option than rushing to the Colombo harbor where SLNS Gajabahu was anchored.

Overall defences in and around Janadhipathi Mandiraya crumbled as crowds surged in the absence of an effective strategy to thwart them. As we recall the law enforcers (both military and police) simply did nothing to halt the advance of the mob right into Janadhipathi Mandiraya, as people, like the then US Ambassador Julie Chung, openly prevailed on the hapless administration not to act against, what she repeatedly termed, ‘peaceful protesters’, even after they, in a pre-planned operation, meticulously burnt down more than hundred properties of government politicos and loyalists, across the country, on 9/10 May, 2022. So they were, on the whole, the proverbial wolves in sheep’s clothing working with the Western regime change project here as was previously done in places like Libya and Iraq and more recently in neighbouring countries like Pakistan, Bangladesh and Nepal to install pliant governments.

After the 9/10 incidents, President Rajapaksa replaced the Commander of the Army, General Shavendra Silva, with Lt. Gen. Vikum Liyanage.

RTI query

M. R. Ali of Kalmuinai, in terms of Section 34 of the Right to Information Act No. 12 of 2016 (read with Article 138), has sought information, in September 2022, regarding the deployment of SLNS Gajabahu. The Navy rejected the request in November 2022, citing Section 5(1)(b)(i) of the RTI Act, which relates to information that could harm national security or defence. Obviously, the release of information, sought by that particular RTI, couldn’t undermine national security. No one can find fault with Ali’s decision to appeal to the RTI Commission against the position taken up by the Navy.

Following hearings in 2023, the Commission issued a split decision on 29 August, 2023. The RTI Commission upheld the Navy’s refusal to disclose items 1 through 5 and item 8, but directed the Navy to release the information for items 6 and 7, specifically, the cost of the travel and who paid for it.

However, the Navy has moved the Court of Appeal against the RTI directive to release the cost of the travel and who paid for it. Having examined the case in its entirety, the Court of Appeal held that the Navy, being the Public Authority responsible for the deployment of the vessel, had failed to prove how they could receive protection under 5(1)(b)(i) of the Right to Information Act. The Court of Appeal affirmed the order dated 29/08/2023 of the Right to Information Commission. The Court dismissed the appeal without costs. The bench consisted of R. Gurusinghe J and Dr. Sumudu Premachandra J.

There hadn’t been a similar case previously. The Navy, for some strange reason, failed to highlight that the failure on their part to act swiftly and decisively during the 09 July, 2022, violence that directly threatened the lives of the President and the First Lady, thwarted a possible catastrophic situation.

The action taken by the Navy should be discussed, taking into consideration the failure on the part of the Army and Police to save the lives of MP Atukorale and his police bodyguard. No less a person than retired Rear Admiral and former Public Security Minister Sarath Weerasekera alleged, both in and outside Parliament, that the Army failed to respond, though troops were present in Nittambuwa at the time of the incident. Had the Navy hesitated to evacuate the President and the First Lady the country may have ended up with another case similar to that of lawmaker Atukorale’s killing.

The Gampaha High Court, on 11 February, 2026, sentenced 12 persons to death for the killing of Atukorale and his security officer Gunawardena.

Let me stress that the costs of presidential travel have been released in terms of the RTI Act. The deployment of SLNS Gajabahu, at that time, has to be examined, taking into account the eruption of Aragalaya outside President Rajapaksa’s private residence at Pangiriwatte, Mirihana, on the night of 31 March, 2022, evacuation of the resigned Prime Minister Mahinda Rajapaksa from Temple Trees, after protesters breached the main gate on 10 May, 2010, and the JVP/JBB-led attempt to storm Parliament on 13 July, 2022. Mahinda Rajapaksa and wife Shiranthi took refuge at the Trincomalee Navy base, chosen by Gotabaya Rajapaksa as sanctuary a few months later.

US Ambassador Julie Chung tweeted that Washington condemned “the violence against peaceful protestors” and called on the Sri Lankan “government to conduct a full investigation, including the arrest and prosecution of anyone who incited violence.”

The US fully backed the violent protest campaign while the direct involvement of India in the regime change project later transpired. As far as the writer is aware, this particular request is the only RTI query pertaining to Aragalaya. Evacuation of Mahinda Rajapaksa took place in the wake of a foolish decision taken at Temple Trees to unleash violence on Galle Face protesters, who were also besieging Temple Trees.

Defence Secretary retired General Kamal Gunaratne told a hastily arranged media conference that the former Prime Minister was at the Naval Dockyard in Trincomalee. The media quoted him as having said: “He will be there for a few more days. We will provide him with whatever security he needs and for as long as he wants.” Mahinda Rajapaksa remained in Trincomalee for over a week before attending Parliament.

Navy’s dilemma

Gotabaya

At the time information was sought under the RTI Act, Ulugetenne served as the Commander of the Navy. Vice Admiral Priyantha Perera succeeded Ulugetenne on 18 December, 2022. Following VA Perera’s retirement on 31 December, 2024, President Anura Kumara Dissanayake brought in the incumbent Kanchana Banagoda, as the 26th Commander of the Navy.

On the basis of the RTI query that dealt with the deployment of SLNS Gajabahu to evacuate President Gotabaya Rajapaksa and First Lady Ayoma, one can seek information regarding the expenditure incurred by Air Force in flying Mahinda Rajapaksa and his wife from Colombo to Trincomalee and back, as well, as Gotabaya Rajapaksa, his wife and two bodyguards leaving the country on Air Force AN 32 on 13 July, 2022. On the following day, they flew to Singapore on a Saudi flight.

Ali, in his representations, stressed that his objective hadn’t been to determine the legality of the Navy’s actions but to exercise his right as a citizen and taxpayer to oversee public spending. He questioned the failure on the part of the Navy to explain as to how revelation of specific information would “directly and reasonably” harm national security. In spite of the RTI Commission directive, the Navy refrained from answering two specific questions as mentioned by justice Dr. Sumudu Premachandra. Question number (6) How much money did the Sri Lanka Navy spent for the travel of former President Gotabhaya Rajapaksha in this ship? And (Question 7) Who paid this money? When did they pay?

Both the RTI Commission and Court of Appeal quite rightly rejected the Navy’s position that the revelation of cost of the deployment of vessels poses a significant threat to national security. That claim was based on the assertion that such financial data could allow third parties to calculate sensitive operational details, such as a ship’s speed, fuel consumption, and operational range. The Navy claimed that the disclosure of sensitive information could reveal supply dependencies, logistics constraints, and fueling locations, making the vessels vulnerable to sabotage or economic warfare.

The Navy sought protection of RTI Act’s section 5(1)(b)(i). Following is the relevant section: “(b) disclosure of such information– (i) would undermine the defence of the State or its territorial integrity or national security;”

The Navy appears to be in a bind over the RTI move for obvious reasons. With the ultimate beneficiary of Aragalaya at the helm, the Navy would find it extremely difficult to explain the circumstances SLNS Gajabahu was deployed against the backdrop of direct threat on the lives of the then incumbent President and the First Lady. The truth is desperate action taken by the Navy saved the life of the President and his wife. That is the undeniable truth. But, the current political environment may not be conducive to say so. What a pathetic situation in which the powers that be lacked the courage to lucidly explain a particular situation. As stressed in the Supreme Court judgment of November 2023, the Rajapaksa brothers – including two ex-Presidents – were guilty of triggering the country’s worst financial crisis by mishandling the economy.

In a majority verdict on petitions filed by academics and civil rights activists, a five-judge bench ruled that the respondents, who all later resigned or were sacked, had violated public trust. The regime change project took advantage of the attack ordered by Temple Trees on 09 May, 2009, on Galle Face protesters, to unleash pre-planned violence on ruling party politicians and loyalists.

If not for the courageous decision taken by Prime Minister Ranil Wickremesinghe, in spite of his private residence, at Kollupitiya, being set ablaze by protesters on the night of 09 July, 2022, to order the military to thwart the JVP/JJB march on Parliament, two days later, and evict protesters from Galle Face soon after Parliament elected him the President on 20 July, 2022, saved the country from anarchy. Although Wickremesinghe, without restraints, encouraged Aragalaya, he quickly became the bulwark against the anti-State project that threatened to overwhelm the political party system.

Obviously, during Wickremesinghe’s tenure as the President, the SLPP, that accommodated the UNP leader as the Head of State, appeared to have turned a blind eye to the RTI query. Had the SLPP done so, it could have captured public attention, thereby making an attempt to influence all involved. In fact, the case never received media attention until journalist and Attorney-at-Law Nayana Tharanga Gamage, in his regular online programme, dealt with the issues at hand.

Before leaving Janadhipathi Mandiraya, the President has warned the military top brass, and the IGP, to prevent the destruction of the historic building. However, no sooner, the President left, the military top brass vacated the building leaving protesters an easy opportunity to take control. They held Janadhipathi Mandiraya until Gotabaya Rajapaksa resigned on 14 July 2022 to pave the way for Ranil Wickremesinghe to become the President.

It would be pertinent to mention that President Gotabaya Rajapaksa only moved into the Presidential Palace (Janadhipathi Mandiraya) after massive protest outside his Pangiriwatte private residence on 31 March, 2022, underscored his vulnerability for an attack.

Village tank cascades, great river quartet and Cyclone Ditwah

Published

4 days ago

2026/03/25

Sahan Weerasooriya

This past November and December Ditwah showed us how dark, eerie and haunting catastrophes cyclones can be. Past generations have suffered as shown in 1911, the Canberra Times reporting the great flood of Ceylon on December 30 of that year. It killed 200 people and left over 300,000 homeless. Half century later, on December 25, 1957, a nameless cyclone brought severe rain to the North Central Province (NCP), and the Nachchaduwa reservoir breached, unloading its full power of volume into Malwatu Oya, a mid-level river flowing through the city of Anuradhapura, nearly washing away its colonial-era bridge near the Lion Tower. A cyclone paid a visit to the Eastern Coast of Sri Lanka on November 17-23, 1978.

Half a century later, Ditwah came with swagger.

Quartet of Rivers

Cyclone Ditwah unleashed disaster and tragedy, terrorising every breath of hundreds of thousands of people. These cyclones come spaced by a generation or two. How the Great River Quartet of Mahaweli, Kelani, Kalu, and Walawe, and their attendant mid-level streams, behaved before Ditwah masks the reality that they are not the loving and smiling beauties poets claim them to be. During the Ditwah visit, our river Quartet showed its true colours in plain sight when wave after wave of chocolate rage pushed uprooted forests creasing islands of floating debris and crashed onto bridges, shattering their potency into pieces. These rivers are nothing more than a bunch of evil reincarnations cloaked in ruinous intentions.

The River Quartet and its mates woke up to the first thunder of Ditwah. They carried away villages, people, property, herds of cattle, and wild elephants to the depths of the Indian Ocean. While we continue to dig out the dead buried in muddy mountainsides, dislodged from their moorings during this flood of biblical proportions, how our rivers, streams, and, particularly, the village tanks handled the pressure on their own will be the core of many future discussions.

The destruction and tragedy caused by this water hurt all of us in many ways. But we all wish they were only a fleeting dream. Sadly, though, the real-life sight of the pulverised railway bridge at Peradeniya is not a dream. This section of the rail line was stripped of its modesty and laid bare. It hung in the air, literally, like strands of an abandoned spider’s web on a wet Kandyan morning. It was a reminder to us that running water is a masked devil and should not be considered inviting. It can unleash the misery with a chilling ending no one wants to experience in a lifetime.

Tank Cascade Systems (TCS)

Although the Ditwah cyclone covered Sri Lanka from top to bottom with equal fury, the mountainous areas and floodplains of our River Quartet surrendered soon. However, the village tanks in the Dry Zone – Northern, North Central, Northeast, and Eastern provinces – weathered that onslaught, sustaining only manageable damage. They collectively mitigated the damage caused by over 200 mm of rain that fell across the catchment areas they represented. Thus, the tank, the precious possession of the village, deserves to be titled as a real beauty.

Let me introduce the village tanks systems our engineering ancestors built with sophistication and ingenuity, a force like Ditwah hardly made a dent in groups of these tanks called Tank Cascade Systems (TDS). Many of the village tanks in the Dry Zone, covering 60% of Sri Lanka’s land area, stand in groups of TDS, separated as individual bodies of water but sharing water from one or more dedicated ephemeral streams. R.W. Ievers, the Government agent for North Central Province in the 1890s, noted that these tanks were the result of “one thousand years of experiment and experience,” and “ancient tank builders took advantage of the flat and undulating topography of the NCP to make chains of tanks in the valleys.” Colonial Irrigation Engineers of the early 20th century also recognised this uniqueness. Still, they could not connect the dots to provide a comprehensive definition for this major appurtenance of the village.

Although these tanks appear to be segregated ecosystems, a closer look at the peneplain topographic map of Sri Lanka shows that each stream feeding them ultimately flows into a larger reservoir or river, jointly or independently influencing the mechanics of regional water use and debouching patterns. This character is the spirit of the dictum of King Parakramabahu centuries earlier: “let not a single drop of water go to waste into the sea without being used by people.” Villagers knew that each tank in their meso-catchment area was related to other tanks on the stream it was in ensuring maximised use of water.

With their embodied wisdom, our ancestors centuries ago configured the placement of individual tanks that shared water from a catchment area. But not until 1985, following a careful autopsy of the pattern of these small tanks in the Dry Zone, Professor Madduma Bandara noticed a distinctive intrinsic relationship within each group of tanks. He called a group of such tanks a Cascade of Tanks. He wrote, “a (tank) cascade is a connected series of tanks organized within a micro-catchment of the Dry Zone landscape, storing, conveying, and utilising water from an ephemeral rivulet.” In short, it is a “series of tanks located in succession one below the other.” Dr. M.U.A. Tennakoon shared the names of the villagers in Nuwarakalaviya used for this configuration of tanks: Ellangawa. On a map, these tanks appear as hanging on a string. Thus, Ellangawa can be a portmanteau, a blend, of these two words.

There are over 475 such cascading tank groups in the Dry Zone. On average, each cascade typically supports four tanks. One cascade, Toruwewa, near Kekirawa, has 12 tanks. According to Professor Madduma Bandara, a cascade of tanks held about 20-30% of the water falling on its catchment area. As I will show later in this essay, the tank cascades behave like buddies in good times and bad times. By undertaking to build a vascular structure to collect, conserve, and share water with communities along the stream path, our ancestors forewarned of the consequences of failing to undertake such micro-projects where they chose to live. The following are a villager’s thoughts on how to retool this concept to mitigate the potential for damage from excess water flow in a larger river system.

To villagers, their tank is royalty. Its water is their lapis lazuli. Therefore, they often embroidered the title of the village with the suffix wewa (tank) or kulam (tank, in Tamil), indicating the close connection between the two. It is the village’s foremost provider and is interdependent. That is why we have the saying, “the village is the tank, and the tank is the village.”

A study in 1954/55 found that there were 16,000 tanks in Sri Lanka, of which over 12,500 were operational. Out-of-commission tanks were those that fell into disuse after the original settlers abandoned them for a host of reasons, such as a breach in the bund, fear of plague or disease, or superstition. Collectively, they supply water to an area larger than the combined area of the fields served by the major irrigation reservoirs in the country at the time.

In some villages, an additional tank called olagama, with its own acreage of fields, receives water from the same stream or from another feeder stream which joins the principal stream above or below the main tank. In the event the main tank is disabled, often the olagama tank can serve as the alternate water source for their fields.

Cultural and Engineering

A tank cascade is also an engineering undertaking. But village tank builders were not engineers with gold-trimmed diplomas. They were ordinary folks, endowed with generations of collective wisdom, including titbits on the physics of water, its speed, and its cruelty. Village pioneers responsible for starting the construction of the tank bund, gam bendeema, placed the first lump of earth after marking off home sites, not immediately below the future bund, but slightly towards one end of it, in the area called gammedda, or the elevated area the bund links to, gamgoda.

Engineering of a tank cascade has a cultural underpinning. It is founded on the feeling of solidarity among the villages along an ephemeral stream. In practice, it was a wholesome area with small communities of kin below each tank sorting out their own affairs without much intervention of the ruling class. For example, during heavy rains, each village in the chain communicated with the villages below the volume in its tank and the projected flow of the stream. When the tank reached its capacity and water began to spill over the spillway, the village below must take measures to protect its tank bund. If it breached, villagers up and down the cascade helped each other repair it.

They were aware that an earthen dam was susceptible to failure, so they used their own town-planning ideas. They avoided building residential zones directly under the stream’s path, generally at the midpoint of the dam. Instead, they built their triumvirate of life – tank, field, and dagoba (stupa) – keeping safety and practicality in mind. Dagoba was always on a higher ground, never supported by beams on a stream bank like what Ditwah revealed recently. We now know what happens to dagobas built on sagging beams by deceptively serenading riverbanks when thunder waters and unworldly debris came down hand in hand.

From top to bottom, the Tank Cascade showed the engineering instinct of the builders and accessory parts that helped its smooth functioning. There was the Olagama and Kulu Wewa associated with a system. Tank builders had an idea of the volume of water a given stream would bring in a year. In conjunction with this, the bunds of the Olagama and Kulu Wewa are built small. In contrast, the bunds of the tanks that formed the lower rung of the cascade are relatively larger. The idea behind this was that, in the event of a breach in an upstream tank, the downstream tanks could withstand an unexpected influx of water.

During the Ditwah’s death dance, the Mahaweli River did not have this luxury as it marched downstream from Kotmale dam. There were not enough dams to tame this river, and its beastly nature was allowed to run wild until it was too late for many.

The embodied imprints of experience inherited from their ancestors’ helped villagers design the tank’s physical attributes. In general, a tank supplied by this stream had a dam of a size proportional to the amount of water it could store for the fields. Later, as the village added families and field acreage increased, villagers raised the bund and the spillway to meet increased storage capacity. This simple practice guarded against eventualities like uncontrollable floods between villages. Excess water was allowed to flow through the sluice gate and the spillway, reducing the pressure on the bund. Had we applied this fundamental practice on a proportional scale to a large stream, i.e., oya or river, it would have lessened the destruction during a major rainstorm, ilk of which Ditwah brought.

With my experience living in a village with its tank, part of a TCS of five tanks, I wish large rivers like the Mahaweli had a few small-scale dams or partial diversions mimicking a rudimentary TCS so that the Railway Bridge at Peradeniya could have avoided the wrath of hell and high-water bringing muck and debris along its 46 km descent from Kotmale, where its lone dam is. I am glad I have company here. Professor Madduma Bandara noted 40 years ago, “much water flows through drainage lines due mainly to the absence of a village tank-type storage system.” Mahaweli turned out to be that drainage line this past November, holding hands, sadly, though, jubilantly, with the designs of Ditwah. Recently, former Head of Geo-Engineering at Peradeniya University, Udeni Bandara Amarasinghe, highlighted the importance of building reservoirs on other rivers to control floods like those we experienced recently.

Check Dams & Macroscopic Control

Within the TCS, the check dams, Kulu Wewa or Kele Wewa – forest tanks above a working tank held back sediments generated by upstream denudation. They controlled the volume and water entering the main tank. Kulu Wewa provided water for wild animals and checked their tendency to raid crops below the main tank. The difference between Kulu Wewa and Olagama was that, because of its topographical location, Kulu Wewa was occasionally used as a source of water for crops when the main tank below it became inoperable due to a breach or was undergoing repairs or used up its water early.

Based on these definitions, each working tank in the TCS also acted like a check dam for the one below it. Furthermore, if a tank in the cascade ran out of water, other tanks in the cascade stepped in. They linked up with the tanks above through temporary canals made by extending an existing minor canal, wella, or the wagala, excess water pan, of an upstream field.

The tank bund tamed and kept in check the three attributes of a stream – water velocity, volume, and its destructive power. By damming the stream, the villagers broke fueling momentum of it. They rerouted it via the spillway at the end of the bund, a form of recycling. Water from some spillways is diverted along a large niyara-like (field ridge) lesser dam, built along the wanatha (flanks) of the field, until it empties into the atrophied stream below the field.

Simultaneously, by controlling the release of water through two sluice gates on the bund, goda and mada horowwa, and directing it to the two flanks of the field, ihala and pahala wanatha, villagers succeeded in tamping down the pressure on the bund. Water from the neutered stream is thus redirected from all three exit points. It must now continue its journey along the wagala, to which field units (liyadi) also empty their excess water. This water is called wel pahu wathura.

After going through this process, the momentum of the ephemeral stream water is passive by the time it reaches the tanks in the lower parts of the cascade, often a kilometer or two downstream. This way, a line of tanks along the stream’s axis now shares the responsibility of holding back its full potential, limiting its ability to cause damage.

Such a break of momentum was lacking in the Four Great River Quartet and their lesser cousins. For the long-term solution to prevent damage from future cousins of Ditwah, we must consider this ingenious water-control method for rivers on a macroscopical scale.

Reservoirs

As Ditwah-type floods occurred in 1911, 1957, 1978, and 2025, with a bit of luck, we can expect to have a few more decades of recess to work on cascading edifices along rivers, such as dams or diversions, before the next flood comes with roguish intentions. The Accelerated Mahaweli Diversion Program (AMDP), started in 1978, took 30 years to complete and now has over a dozen reservoirs between Kandy and the Dry Zone coastal belt, holding back its might. These reservoirs held their ground while Ditwah rained hell, so consulting the TCS’s ingenuity, though seems antiquated, is a good investment.

As soon as Cyclone Ditwah began to make noise, word spread that releasing water from a few of them on the Mahaweli and Kelani rivers could have made a difference. The problem with the Kelani River basin in Western Province and the Mahaweli basin in Central Province above Kandy is that, despite their combined population being nine times that of the NCP, they only have six reservoirs. On the contrary, the NCP has twice as much in the lower Mahaweli River basin, built under the AMDP. Furthermore, the NCP also has many ancient reservoirs it inherited from our ancestors. A string (cascade) of large reservoirs or minor dams in the hill country could have helped break the river’s energy which it accumulated along the way. G.T. Dharmasena, an irrigation engineer, had already raised the idea of “reorienting the operational approach of major reservoirs operators under extreme events, where flood control becomes a vital function.”

Unique Epitaphs for the Cyclones

The processes discussed above could have prevented the destruction of the railway track at the Peradeniya bridge, the image of which now stands like a pictorial epitaph to the malicious visit of the Ditwah and a reminder to us, “what if…?” or “what next…?”

As mentioned at the beginning of this essay, when the 1957 Cyclone dropped heavy rain on the NCP, a Railway Department employee at Anuradhapura made an exceptional effort to keep the memory of that saga for posterity with an epitaph still visible 70 years later. This person memorialised his near escape from the Malwatu Oya flood. As the river roared past over the railing of the bridge near the Lion Pillar roundabout, this employee, probably trapped in his two-storied house near the roundabout, day-stamped the visit of the flood with a red line on the wall of his house to mark the height it reached to trap him.

Three meters from the ground, right between two archtop windows facing the road to Sri Maha Bodhi, he wrote, “Flood level” in Sinhala, Tamil, and English. Right below it, at the end of the faded line, he added, “1957-12-25.”

As Cyclone Ditwah came along, the current resident of the house was not going to break this seven-decade-old tradition. After the flood receded this time, this duty-bound resident drew a line in blue ink and wrote at its end, ‘2025-11-28’, his contributing epitaph reminding us of infamous day Ditwah showed her might by driving the river off its banks. (See picture)

He added a coda to his epitaph – the numeral “8” in 28 is written in bold!
