HYDERABAD: The Hyderabad Metropolitan Development Authority (HMDA) has invited bids for upgrading the Sewage Treatment Plants (STPs) of the Hussainagar to double their existing capacities. Three Sewage Treatment Plants with capacities of 10 million litres per day (MLD), 40 MLD, and 60 MLD will be upgraded from five MLD, 20 MLD, and 30 MLD respectively at an estimated project cost of ₹127 crore.
Officials from HMDA stated that the present STPs are not sufficient to treat the entire inflows into the lake from upstream. The bidder will have to set up the infrastructure along with the plants and look after the operation and maintenance for the next 20 years. Officials have yet to confirm if the STPs would treat the entire inflows before reaching the lake.
The STPs are located at IDL Lake, Kukatpally (5MLD), near KIMS hospital, Patigadda (30 MLD), and near Indira Gandhi rotary (20MLD).
