The Government of Tamil Nadu laid the foundation stone for the development of the underground sewerage scheme in Hosur city of Krishnagiri district in Tamil Nadu.
The project will be implemented in two phases. In the first phase, a 12.51 million litres per day (mld) sewage treatment plant (STP) at Santhapuram and 20.13 mld capacity STP at Ramanaikken will be developed. These STPs use sequential batch reactor (SBR) technology and cover 35 wards partially or fully in the Hosur City Municipal Corporation (HCMC) area out of 45 wards. This phase is being carried out on a design, build, operate and transfer (DBOT) basis at an estimated cost of Rs 5,825.4 million. The remaining wards will be covered under the second phase.
