  "account": "Sri Lanka, with a rich hydraulic heritage, has faced a growing challenge in maintaining the health of its urban water bodies. Despite taming rivers and constructing large reservoirs since gaining independence, lakes and canals in cities are now polluted, resembling the Augean Stables. Two such lakes, Gregory in Nuwara Eliya and Beira in the hills, are particularly concerning.\n\nLake Gregory, a picturesque lake in Nuwara Eliya, embodies this paradox. Its serene surface conceals serious health risks due to highly polluted waters, according to the Central Environmental Authority (CEA). The pollution stems from agricultural runoff and urban wastewater, with sources like fertilizers, pesticides, sewage, and domestic waste. Despite this, no action has been taken to mitigate these sources. The lake is a popular tourist attraction, but visitors are unaware of the health risks posed by swimming in contaminated waters.\n\nBeira Lake, in contrast, is even more polluted. Its contamination is largely due to untreated sewage, illegal sewer connections, urban runoff, solid waste, and industrial discharges. Recent research has highlighted excessive levels of organic pollutants, nutrients, and, in some areas, heavy metals. This has led to algal growth, contributing to the lake's characteristic green appearance.\n\nBoth lakes present a significant challenge that requires urgent action. Experts emphasize the need to identify and block illegal sewage connections, intercept polluted stormwater, and divert it for treatment. While some countries have successfully restored their urban lakes, Sri Lanka's lack of political will is a major hurdle. An official warning about the severe pollution could at least alert the public to the risks. The restoration of these vital lakes is crucial not just for the environment, but also for the thousands who enjoy recreational activities on them.",

It has tamed rivers and built huge reservoirs since Independence, but lakes and canals in its urban […]",
