Facing criticism over its handling of the city’s water supply crisis, Thane Municipal Corporation (TMC) is turning to tighter monitoring to plug leakages, curb water theft and regulate distribution among others as it braces for prolonged scarcity amid the potential impact of El Niño. TMC plans 40 new borewells, repairs existing wells and uses advanced technology to detect pipeline leakages. The civic body is also targeting illegal connections and promoting treated wastewater.
