Water Supply
It is recommended that the maximum on-site water demand be assessed and the water supply be tested to ensure it can meet these
requirements.
It is important to note that a high mains water pressure will not always guarantee high flow rates. Ensure a site pressure reading is taken under
working conditions, as a high-pressure reading from static conditions may not be indicative of the working pressure. The minimum mains
water supply requirements should be 0.15MPa (1.5 bar) working pressure, and a 20 litres per minute flow rate Where mains inlet pressures
