Senior officials of the water resources department, engineers and technical experts were present during the inspection.
During the visit, the minister examined the installation of the advanced trilateral block filter underdrain system, which is being introduced as part of the upcoming 100 MLD WTP expansion project at Selaulim.
Officials informed that one of the key components of the expansion project is the construction of mono-media filter bed units aimed at improving filtration efficiency and ensuring optimum production of treated water from the plant.
Engineers explained that the filtration unit mainly consists of filter media and the filter underdrain system, with the latest trilateral block underdrain technology being implemented at the project site.
The technology, reportedly being used for the first time in India, has been developed by Xylem-Leopold, UK, and is being executed by M/s Laxmi Civil Engineering Services Pvt Ltd, Kolhapur, under the supervision of overseas experts.
Officials further stated that the trilateral block underdrain system ensures effective combined air and water backwashing, reducing filter wash periods and improving filtration efficiency. The underdrain material is made of virgin HDPE material with an operational life of more than 40 years.
Phal Dessai stressed the need for timely completion of the project while maintaining quality standards to ensure reliable drinking water supply for the people of Goa.
Senior WRD officials and engineers briefed the minister on the technical aspects and assured that the work is progressing as per schedule.
