In an effort to measure non-revenue h2o and transportation retired a broad h2o audit, Chennai Metrowater is successful the process of installing electromagnetic travel meters crossed each its h2o attraction and organisation facilities successful the city. The bulk metering task is expected to beryllium completed by March 2026.
While strengthening root availability and proviso management, the h2o bureau has progressively turned its absorption to demand–side absorption and conserving resources, including reducing leakages, replacing ageing infrastructure and adopting a broad metering policy.
Non-revenue water
The h2o bureau has estimated that non-revenue h2o contributed to 20%-30% of the h2o supply. Officials of the Metrowater said enactment is nether mode to hole 518 IoT-enabled travel meters to measure the h2o quantity received astatine attraction plants and distributed done the network.
At present, the quantity of h2o received, treated, and supplied is mostly calculated based connected pumping operations. Once the bulk metering task is completed, the h2o bureau would beryllium capable to precisely place h2o losses, way h2o depletion and show h2o drawal and organisation successful existent time.
Over 1,000 mld
On an average, Chennai is supplied with astir 1,226 mld (million litres a day) of drinking water.
Of this, home consumers successful the metropolis and added areas are provided with astir 1,173 mld done pipelines and tankers.
The ₹44.93-crore task covers travel measurement crossed attraction and organisation network. Nearly 277 specified travel meters person been fixed successful pipelines varying from 500 mm to 2,000 mm successful size astatine assorted places, including lines conveying h2o to organisation stations and besides astatine receiving constituent of h2o organisation stations.
Hydrostatic sensors
Hydrostatic h2o level sensors are besides being installed successful underground sumps and overhead tanks.
The metropolis has a h2o attraction capableness of 1,510 mld successful 9 facilities, including 1 successful Veeranam. Treated h2o is distributed done 16 large organisation stations to localities crossed the city.
The h2o bureau is fixing bulk h2o meters successful 33 organisation lines astatine Kilpauk Water Works, the city’s archetypal h2o attraction plant. It is from present that assorted parts of northbound and cardinal parts of Chennai, including Kellys, Perambur and Ayanavaram, person their regular supply.
Officials said the information generated would beryllium transmitted to a cardinal dash board, with engineers receiving automated alerts.
