The water tariff in Coimbatore for apartment buildings is Rs. 900 for the initial 5000 litres. Then it is Rs. 5.25/litre till 7500 litres, Rs. 6/litre from 7501 till 10000 litres, Rs. 8/litre from 10001 to 150000 litres, and Rs. 11/litre after 150001 litres. These tariff rates however do not include the 11 local bodies that were newly added under the Coimbatore Corporation. These areas are Kurichi, Kuniamuthur, Kavundampalayam, Veerakeralam, Vadavalli, Thudiyalur, Kalapatti, Saravanampatti, Chinna, Vedampatty and Vilankurichi. If you are going to be living in any of these areas, then you will have to pay the old water tariff. Due to lack of metered water connections, the residents of these areas pay flat amounts of Rs. 30, Rs. 50, Rs. 55, Rs. 60 or Rs. 100.
For a domestic home the water tariff is – 150001 litres – Rs. 10/litre For bulk supply to a residential apartment building – 150001 litres – Rs. 11/litre
After the increase in water supply rates in Coimbatore, you will have to pay a monthly minimal amount of Rs. 100 for the first 15000 litres of water. If you live in an individual house, then for use of every 1000 litres of water after the initial 15000 litres, you will have to pay Rs. 6 till 20000 litres, Rs. 8 for every litre from 20001 litres till 150000 litres, and Rs. 10 per litre from then on.
