The Delhi Jal Board (DJB) has clocked a revenue increase of Rs 170 crore in 2015-16, mainly because of improved working, monitoring of water and sewage management, Chief Minister Arvind Kejriwal said here on Saturday, while releasing its annual report.

"Swiftly implementing its poll promises, the Delhi Government implemented the provision of free water up to 20 kiloliters per family per month. This policy has benefited all stakeholders: citizens reaped rewards of zero billing, the cross subsidy bolstered revenue and incentivised lower usage,” Kejriwal said.

Listing out the improvements, Water Minister and DJB Chairman Kapil Mishra said the mSeva App drove bill generation, online payments and resolution of inflated bills.

Mishra said, a transparent tanker water distribution system was implemented using GPS/GPRS with schedules of operation available online, eliminated unscrupulous elements operating in water supply through private tankers at charging exorbitant rates.

A DJB statement also said that regularisation of unauthoriaed connections, provision of water to over 250 unauthorised colonies and reduction in sewerage and water development charges had brought water to the poorest in Delhi.
