The tankers are fitted with GPS to check water theft and will enable consumers to track their movement.
Until now, the DJB was operating 407 stainless steel tankers and 385 mild steel tankers to supply water in the deficit areas of Delhi.
Water Minister Kapil Mishra flagged off the new fleet of stainless steel tankers from the Delhi Secretariat here in presence of DJB CEO Keshav Chandra.
Induction of the new tankers, of which 192 are of 4kl capacity and the rest of 9kl capacity, became necessary as the tankers purchased in 1998 have "outlived their utility or useful life", DJB said in a statement.
"The movement of these water tankers can be seen on the smart mobile by the users. Anybody in public domain can track the vehicles and its timings," it said.
