Water Management Technology Contract

This procurement opportunity involves the supply of specified goods detailed in Appendix 1, which includes technology for infiltration structures and retention tanks. The project focuses on managing rainwater runoff from building roofs through external drainage systems. Roof drainage pipes are equipped with sediment traps, and the main PVC downspouts (125 mm) connect to 6500-liter retention tanks or rain gardens. Overflow from these tanks or rain gardens is directed to infiltration structures. The infiltration systems will utilize blocks measuring 0.8 m x 0.8 m x 0.35 m, which will be installed on the foundation slabs of the infiltration areas. An inlet shaft will be integrated into the infiltration structure, serving as a filtration chamber with cleaning and inspection capabilities. The shaft will be topped with a cast iron telescopic cover that allows for adjustment to the ground surface.
