a) General DescriptionRaw shall be supplied from municipal water main through new water meter.Assume that water main pipe is provided along the site boundary.The water reservoir shall be separated by two(2) outside the building as illustrated on attached sketch.The in-coming water through multi-media sand filter is stored in once RC made fire water reservoir w/capacity of 369m3 and replenished into domestic water reservoir w/capacity of 400m3 (1 day storage of potable water, make-up water to cooling tower, steam boiler feeding water, Producing Pure water and Process use)Domestic water shall be supplied from inverter controlled booster pump unit c/w hydro-pneumatic pressure vessel as overall water source including make-up cooling tower, and water supply for maintenance.The pumps shall be capable of developing the required total head at rated capacity for continuous operation. It should be give satisfactory performance at any point on the H-Q curve over a range of 75% of rated flow to 125% of the rated flow. The maximum efficiency shall preferably be within ±10% of the rated design flow.In this work, domestic water supply system (including make-up water and greenery irrigation supply) and water supply system to generate pure water shall be separated as individual system.
