CMWSSB – How to Make Chennai Metro Water Tax on the CMWSSB

Why is Water Taxed in Chennai?

• Water is taxed in a variety of ways, including VAT and tap water charges. These prices encourage companies and individuals to utilize water more efficiently.

• Even if people have access to water in surrounding ponds, lakes, and rivers, it takes a lot of resources to offer clean, chlorinated piped water. If the user does not pay, the town municipality that delivers piped water bears the cost. Because the water subsidy is paid for using municipal tax dollars, less money is available for other critical municipal services.

• Furthermore, even with needs like free electricity and water, there is plenty of room for waste. Because there is no expense involved with water consumption, people consume six buckets of water for a bath or laundry when two buckets would suffice. Furthermore, they constantly overfill the bucket with tap water. People make use of free resources accessible to them.

• We must remember that until a fee covers the cost of delivering water, there will be no money to invest in new water treatment and purification facilities for a rising metropolitan population. The cash generated by the water taxation scheme is utilized to treat the city’s wastewater.

Calculate Chennai Metro Water Bill Payment

Users can calculate their water tax costs on the CMWSSB website. Log on to the CMWSSB website and pick Water Tax and Charges Payment from the list of online services to calculate the fees. Now, click the Water and Sewerage Tax Calculator button. The half-yearly tax is calculated by multiplying the Corporation of Chennai’s annual rental value by 3.5%.

Water and sewerage taxes/charges must be paid in August for the first half-year and in February for the second half-year.

How is the CMWSSB’s water charge calculated?

The installation of water meters is required under the Chennai Metropolitan Water Supply and Sewerage Act of 1978. Water meters, according to the Act, would allow the Board to compute how much the owner owes for water usage based on actual consumption as verified by readings from the meter installed on the property. Only the commercial circuit, however, has had success with water meter installation.

Every family (individual houses, bungalows, and flats with less than 50 units) that receives its water supply from the Metro water agency through pipelines pays a set monthly price of Rs 80 as water rates.

Quantity consumed in total	Rate per kilolitre (in Rs)
Up to 10 kilolitre	Rs 4.00
11 to 15KL	Rs 16.00
16 to 25 KL	Rs 24.00
Above 25 KL	Rs 40.00

Due to the lack of piped water in many sections of the city, residents must rely on CMWSSB tankers** (along with other sources like borewells and private tankers), which offer water at the following rates:

Capacity of lorry	Payment Tariff for domestic purposes (in ₹)	Rate per kilolitre (in ₹)
6 KL	475	79.17
9 KL	700	77.77
16 KL	1200	75

The current Metrowater scheme is described as unfair and regressive in the white paper because it levies a flat rate for domestic connections, favoring those who live in large homes and use a lot of water while still paying the same rate as those in the lower or middle economic strata who use a lot less water per person.

Domestic homes pay Rs 40 per month for sewage collection. Residents in disconnected areas can reserve sewage vehicles for Rs 650 per 6000 gallons through CMWSSB to empty their septic tanks.

Chennai’s Water Tax Rate 

Chennai levies a water tax of 1.5% of the assessed yearly value. At the same time, the sewerage tax is 5.5% of the annual assessed value. You may use this online portal to apply for a new water connection, pay your Chennai metro water bill, file complaints, and more. You may also use the Metro Water App, which is available on the Google Play Store, to file a complaint or grievance.
