Addressing an event organised by Bengaluru Environment Trust Balasubramanian informed that the restoration and rejuvenation of lakes, stormwater drains, improved sewage treatment plants together cost Rs 50,000 crore, a high price to pay for the mistakes of the past 15-20 years.
He further added that a comprehensive policy on water management was needed and a project is being prepared by engineers from a reputed consultancy firm and the estimated cost has gone up from Rs 40,000 crore to Rs 60,000 crore. The draft report recommends a sanction of Rs 10,000 crore for several other segments, including public education, he added.
Speaking to Deccan Herald Balasubramanian said that the public has to realise that micro-studies and isolated attempts by NGOs, educational institutions and citizens will not be able to restore and rejuvenate lakes.
