No New Underground Drainage System for Tirupati, Focus on Upgrading Existing Network
Municipal Administration Minister P Narayana has informed the Andhra Pradesh assembly that there is currently no proposal to construct a completely new underground drainage (UGD) system in the temple city of Tirupati. However, he assured that the government will strengthen and upgrade the existing network based on financial feasibility.
Current Drainage Challenges in Tirupati
Tirupati, with a resident population of 4.5 lakh and a floating population of up to one lakh daily, generates nearly 54.5 million litres of liquid waste per day. The minister emphasized that this necessitates a robust drainage system to safeguard sanitation and public health in the city.
UGD Coverage and Infrastructure Needs
UGD coverage is required across 408.4 km in Tirupati. At present, 284.3 km is in place, leaving 125 km yet to be taken up. Additionally, 60 km of the old network requires replacement due to ageing infrastructure, which poses risks to efficiency and environmental safety.
Cost and Implementation Plan
Replacing old lines and laying new pipelines in uncovered areas would cost approximately ₹152.45 crore. In the first phase, tenders will be invited in March to replace 7.5 km of old lines. For the remaining stretches, the state government will seek central support to mobilize funds and proceed in phases, ensuring a systematic approach to infrastructure development.
Broader Statewide Perspective
Presenting a broader picture, Minister Narayana stated that Andhra Pradesh requires UGD systems over 21,170 km, at an estimated cost of ₹24,000 crore. Currently, 3,334 km is operational, while works covering another 2,860 km are underway. He emphasized that completing UGD networks is essential to achieve the goal of ‘Swachh Andhra’ and assured that expansion will continue in line with the state's financial position, prioritizing public health and urban cleanliness.
