The water supply and sanitation department will be issuing challans to Mohali residents who are found wasting water between June 13 and July 31, in order to maintain sufficient supply this summer.

The area under the department includes Phases 1 to 11, Sectors 70 and 71, Industrial Area Phases 1 to 5 and 7, Mataur, Madanpur and Shahimajra villages.
As per the notice, watering lawns, washing courtyards and vehicles is prohibited between 5.30am and 8.30am. If a resident is found violating the order, a notice will be issued. First time violaters will have to pay ₹1,000 and for the second time a fine of ₹2,000 will be imposed. In case of third time violaters, a fine of ₹5,000 will be imposed and the water supply will be disconnected.
Executive engineer Anil Kumar said teams from the water supply department will do random checking during morning hours to keep a check on violators.
Mohali Area Development Authority (GMADA), which has sector 66 to 80 is yet to start issuing challans to violaters.
Mohali, on an average, requires 30MGD (million gallon daily) of water, but the supply is limited to 20MGD—10 MGD from the Kajauli waterworks and an equal amount from 75 tubewells. During the peak of summer, the demand reaches 32MGD, causing a shortfall of 12MGD.
