In A bid to check the problem of water contamination in the city, the Brihanmumbai Municipal Corporation (BMC) has begun the process of mapping areas that register a high number of such cases. The exercise, civic officers said, would help them identify old, leaking pipelines required to be repaired or changed immediately.
BMC hydraulic engineer Ashok Tawadia said, “We are mainly going to look at areas from where we get continuous complaints (of contaminated water). We will also collect more water samples and immediately send detection teams to the spot to understand the reasons. The mapping will be primarily done on the basis of local complaints.”
The BMC, on a daily basis, conducts tests on samples collected from every ward at the Dadar and Bhandup water treatment complexes. The civic body’s health and the water department work together to submit reports on water contamination every month.
Last year, BMC registered highest number of water contamination complaints in the month of June, just after the onset of monsoons. The monsoon also witnesses a surge of E Coli bacteria, associated with water-borne diseases, being found in water samples. This is a result of the rise in underground water level.
A senior civic official said, “A majority of the pipelines in the city are more than a century old. At a lot of places, the drainage lines run along the water pipelines resulting in contamination, especially in the case of a leakage. We are undertaking the mapping to try and create an inventory of these pipelines to solve the problem on an immediate basis.”
Recently, the civic body had also undertaken a mapping of areas that reported a high number of dengue and malaria cases every year. The municipal commissioner had also warned civic officials of suspension if effective measures were not taken to check spread of water-borne diseases.
