New reservoir will be able to store only one third of capacity

This northeast monsoon, the upcoming Thervoy Kandigai-Kannankottai reservoir will be able to store water up to one-third of its capacity.
Though the Water Resources Department (WRD) had planned to complete the project in October, officials say that it will take six months to complete the remaining works.
This is the fifth reservoir being created to cater to the drinking water requirements of the city. The Rs.380-crore project, which was launched in 2013, is in progress to link the waterbodies in Thervoy Kandigai and Kannankottai to form a reservoir, and cater to the city’s water requirements. The reservoir will have a capacity to store 1,000 million cubic feet, when filled twice a year.
WRD officials said nearly 83% of the work had been completed. This includes work to construct a 8.6 km-long canal to intercept the Kandaleru Poondi canal and bring water to the new reservoir.
However, a portion of the major component to build the bund, which will run for a distance of 7.5 km, needs to be completed.
Most of the bund has been constructed, except for three openings. While an inlet needs to be built to cover one opening, alternate roads have to be identified to close two other openings, officials said.
Work is in progress to provide stone revetment on the earthern bund. “It is becoming a challenge to carry out work, due to consistent rainfall in the region. Lorries, with a capacity to carry 30 tonnes of materials, are unable to get to the site. We need 100 days to complete the work,” said an official.
The project ran into problems due to delay in land acquisition, and several deadlines had to be changed. Work to construct a 66-km-long pipeline to transport water to the Poondi reservoir is yet to be completed.
Steady inflowOn the other hand, the Poondi reservoir in Tiruvallur district continues to get a steady inflow from the Kosasthalaiyar river and various channels. The lake has a storage of 433 mcft and received an inflow of 784 cusecs.
Desilting of nine channels, including the Ellapannaidupettai channel, the Narthawada channel and the Thirupatchur channel, helped in bringing maximum flow of floodwater into the reservoir, officials added.
