Tetuljhura Well Field inauguration today

Taqsem Ahmed Khan, Managing Director of Dhaka Water and Sewerage Authority (DWASA) will inaugurate the first phase of Tetuljhura-Vakurta-Well field Water Supply to Dhaka city this morning. The project set up at Tetuljhora near the Bangshi River in Savar will supply 15 crore liters of water to the capital city every day in 2018, sources in the DWASA said.

The water from this project will bring specially for the dwellers of the capital's Mirpur and  Shah Ali areas, the sources said adding that the ground water has been depleted at most of the places in the city. The DWASA will also construct a water treatment plant at Tetuljhora village under Savar upazila for using the raw water of the Bangshi River, another source said. The works of two other phases of this project will start after end of the first phase.

DWASA is currently dependent on groundwater. It is capable to produce 2420 million liters of water per day on an average. A total of 78 percent of this water comes from the underground sources and rest 22 percent from the surface source.

Ground water is abstracted by using a total of 702 deep tube-wells. Presently, surface water is supplied by treating water of the Shitalasha and Buriganga through four water treatment plants in the city.  DWASA supplies water to Dhaka and Narayanganj. At present, approximately 17.75 million people live in metropolis areas of Dhaka and Narayanganj.

It is mentionable that groundwater level is depleting by 3-4 meters per year due to continuous abstraction of water. For this reason, DWASA has pointed out the importance of reducing dependency on groundwater by supplying water from the surface water as an alternative and sustainable source.At present, 45 million liter of water is supplied daily by treating the water of Shitalaksha through Saidabad Water Treatment plant.

DWASA is going to replace all water pipelines of the city through introducing DMA system (District Metering Area), the sources said adding that it is first even introduction in Bangladesh among the SAARC countries. This system will be managed under the System Control and Data Acquisition (SCADA) system, which will reduce Non-Revenue Water or System Loss as well. 

Furthermore, the projects for constructing two additional mega water treatment plants at Padma (Jashaldia) Water Treatment Plant and Dhaka Environmentally Sustainable Water Supply Project are going on.   DWASA has 420 diesel-driven generators including 42 mobile generators that help maintaining the abstraction of water from underground during the interruption of power supplies.

Besides, over 200 tube-wells have duel-electricity connections for uninterrupted water supply during the load-shedding. Meanwhile, DWASA supplies water through using 31 water carriers and 44 trolleys in the city during crisis of water.
