Supply that arrives on a schedule
BWSSB has long supplied many areas on alternate days, and outer layouts have at times received water once a week. Cauvery supply covers only part of the city's need: around 1,460 MLD drawn against demand estimated at about 2,600 MLD. Apartment sumps have to catch every window.
How we fix it
A multi-tank level controller starts the pump set only when the sump has water and fills each block's overhead tank in turn, stopping cleanly at full, so nobody has to wait up for the supply hour.
