Apartments waiting on the main
Figures reviewed by the state in January 2026 put the BMC area's demand at about 304 MLD against existing capacity of 238.5 MLD, with the 65.5 MLD gap met from groundwater. WATCO expects to supply all apartments and institutions only once a new 130 MLD plant at Mundali is commissioned, so until then many societies run on borewells and sumps.
How we fix it
We size the borewell pump, sump and a hydro-pneumatic pressure system together, and a multi-pump controller holds steady pressure on every floor while sharing duty across the pumps.
