If you believe that water supplied by a civic body is impure and has odour, you should check water supplied by Surat Municipal Corporation (SMC).
As per tests, the water is purer and cleaner than that available in bottles, packed locally. The tests are being conducted by SMC at its own laboratory as per international standards. Samples have also been collected as per world standards.
"Water which SMC supplies is much better than that bottled and sold by local companies. Sometimes, they simply fill civic water in bottles claiming it is mineral water. People believe them and tend to think civic water is unclean," said Jatin Shah, city engineer of SMC. Following complaints about water being supplied in the city, SMC conducted tests on raw water and water post treatment.
Raw water was collected from sources near four water treatment plants — Sarthana, Varachha, Rander and Katargam. For testing, SMC used guidelines prescribed by the Central Pollution Control Board (CPCB) and IS: 10500:1991.
According to test results, zero colour was found in treated water at all four treatment plants, while relaxable limit as per guidelines is 25. The case of odour and taste was the same. Turbidity of treated water was less than 1, against relaxable limit of 10. In chemical parameters also, civic water is much ahead in purity than prescribed limits. The pH level of treated water was less than 8, with desirable level being 8.5. In hardness, the level was less than 200, while relaxable hardness level prescribed is 600.
Against relaxable limit of .3, no iron was found in treated water at all four plants.
The case with nitrates, chloride, alkanity and fluoride is the same. Water supplied by the civic body has much lower content of these than relaxable limits. Also, no coliform, E.coli and fecal matter were found in treated water.
"Water is passed through eight different levels during purification process. Plants are shut down twice a year for cleaning and disinfection. Water samples are tested from time to time. Strict compliance is maintained," said JK Shah, hydraulic engineer of SMC.
He said that the treatment plants use the latest equipment.
