The Bangalore Water Supply and Sewerage and Certain Other Laws (Amendment) Bill 2009 proposes imprisonment for up to six months for those who misuse the water supplied by the Bangalore Water Supply and Sewerage Board (BWSSB). Failing to maintain house connections in conformity with regulations and non-domestic usage of water supplied for domestic purpose would also attract penalty.

The board has also been empowered to insist building owners to adopt rainwater harvesting and recycle waste water. The amendment also proposes that the developers of apartments and high-rise buildings in the limits of city corporation pay pro-rata charges towards cost of improvement of water and sewerage systems.

BWSSB levies the charges time to time.

A committee headed by a retired chief engineer has prepared the amendment bill. The committee studied the practices adopted by several cities such as Chennai, Hyderabad and Delhi before finalising the provisions.
