Chandigarh: To upgrade and expand the city’s water infrastructure under the AMRUT 2.0 tertiary treated (TT) water supply project, a team of experts from the Municipal Corporation (MC) visited the manufacturing plant in Gwalior, Madhya Pradesh, to inspect HDPE pipes of various sizes, including 160 mm, 200 mm and 250 mm.
Project to save 20-25 MGD potable water
Chandigarh’s existing 437-km TT water supply network is the oldest of its kind in the country. TT water is being supplied from STP Diggion to Sectors 1 to 16. The beneficiaries include 4,300 households, 1,200 parks and green belts and five fountains. Tertiary treated water is also used for various other non-potable applications such as industrial use, crop irrigation, washing of trees, cleaning of roads through mechanised road cleaning machines to suppress dust and gardening through tankers, saving a total of 7-10 MGD of freshwater. After the completion of the AMRUT 2.0 TT water supply project, the entire city including all villages will get TT water facility, which will reduce the consumption of freshwater by 20-25 MGD, thereby reducing the burden on groundwater sources. Municipal Commissioner Anindita Mitra said that after the completion of the AMRUT 2.0 TT water supply project, the entire city including all villages will get TT water facility, which will reduce the consumption of freshwater by 20-25 MGD, thereby reducing the burden on groundwater sources. The inspection process involved a thorough visual and physical check of the pipes to ensure that they meet all the required quality standards. This included checking the quantity, marking, colour and finishing of the pipes, as well as measuring key dimensions such as outer diameter, length and wall thickness.
Additionally, several tests were conducted to assess the structural integrity and performance of the pipes, including hydrostatic characteristics, melt flow rate (MFR), density, elongation at break, tensile yield strength, ovality and blue stripe width and depth. Carbon black content and dispersion were also evaluated to verify compliance with IS-4984:2016 standards. Sharing details about the project, Mitra said that the purpose of sending a team for inspection was to ensure the quality and reliability of HDPE pipes, which was an important milestone for the AMRUT 2.0 TT water supply project. By taking this important step, the MC is working towards improving water delivery and distribution for the residents of Chandigarh. He said the existing 437 km long TT water supply network of Chandigarh is the oldest of its kind in the country, supplying TT water from STP Diggiyan to Sectors 1 to 16. The beneficiaries include 4,300 houses of one kanal and above size, 1,200 parks and green belts and five fountains. Besides, TT water is also used for various other non-potable applications like industrial use, crop irrigation, tree washing, road cleaning through mechanised road cleaning machines for dust suppression and gardening purpose through tankers, leading to overall savings of 7-10 MGD.
