Infrastructure projects, housing societies, and slum clusters may face water shortages as the Mumbai Water Tankers Association (MWTA), plans to suspend services from April 10. Mumbai: Mumbaikars, beware, as residents are being urged to save water with the city facing a looming water crisis. The Mumbai Water Tankers Association (MWTA) has warned it will suspend its services from April 10 in protest against the civic body’s directive to private ring well and borewell owners, asking them to stop supplying water to tankers and secure a fresh licence from the Central Ground Water Authority (CGWA).
