Thiruvananthapuram Corporation sanctions ₹124.35 crore for sewerage line extension
The Thiruvananthapuram Corporation has sanctioned ₹124.35 crore as part of works for extension of sewerage line in the capital, especially to the coastal areas. The sewerage line extension work will cover a total of 42.7 kilometres through Muttathara, Beemapally, Beemapally East, Manikyavilakom, Chakka, Pettah, Perunthanni and Kadakampally wards.
The civic body had earlier sanctioned ₹91 crore for a 26.8-kilometre sewerage line connecting Attukal and Ambalathara wards as well as ₹66.5 crore for another line connecting the Attukal and Kalady wards. According to the Corporation's estimates, as many as 7,338 families will benefit when the sewerage line extension works are completed.
Tertiary treatment
For setting up a tertiary treatment plant for improving the quality of the treated water from the sewage treatment plants for reusing it for gardening and construction purposes, the Corporation has sanctioned ₹15 crore. The civic body has also sanctioned ₹36 crore for the setting up of an omni processor to treat the sludge from the sewage treatment plants and to convert it into useful energy. Mayor Arya Rajendran said in a statement that with the projects becoming a reality, there will be a quantum jump in the sewerage connectivity in the city, benefiting a large number of people.
The Corporation is also set to implement a project to install compact sewage treatment plants at Rajaji Nagar in the Thampanoor ward as part of measures to curb the flow of untreated sewage into the Amayizhanjan canal. The proposed plants will have a total capacity of 500 kilolitres per day (KLD) and will be built at an estimated cost of ₹7.02 crore.
Plant at medical college
As per the City Water Balance Plan, which collected data on sewage and septage connections in 2023 to assess gaps, out of the 101.48 million litres per day (MLD) of sewage that the city generates only 56 MLD gets treated in the treatment plant at Muttathara. In addition, a treatment plant with a capacity to treat 5 MLD waste became operational on the Government Medical College campus in 2021. It takes care of mainly the waste generated on the large campus.
Several wards of the city are still unconnected to the sewerage network. The Thiruvananthapuram city Corporation's Budget in 2023 had made a commitment to expand the sewerage network, which is now limited to 43 wards, to all the 100 wards within the next seven years.
