Source: Indian Express, Chennai, Oct 18, 2017:- A canal from Red Hills lake which drains excess water
during monsoon is flanked by a garbage dump, resulting in leachate and possible
contamination of water when the lake fills up.The Red Hills lake, popularly
known as ‘Puzhal lake’, serves as one of the biggest rain-fed reservoirs that
serves the city. The lake can hold a maximum of 3,300million cubic feet (mcft) of water. When
the reservoir fills up, water drains out through the outlet that runs adjacent
to the Ponneri highway. The outlet is surrounded by garbage dumps, which seems
to have replaced grass and shrubs.
