In a bid to bring in uniformity in water charges collected, as well as in the accounting systems in the expanded areas of the city, Chennai Metrowater will soon appoint a consultancy firm. The chosen firm will also identify and evaluate infrastructure and study the facilities available in the added areas. Metrowater has entrusted this work to the Tamil Nadu Urban Infrastructure Financial Services Limited.

The 42 local bodies that were merged with the Chennai Corporation recently, have different rates of monthly water charges collected from residents, as well as different systems of accounting for these charges.
