WebThe above design parameters are represented graphically in Figure 1. A special case exists for gravity sewers below pumping stations. Pump capacities to meet the peak wet weather flow are required and so even in the early years of a scheme the flows to flush the downstream pipes are assured. The above design guidelines are used in the illustrative Web13 Aug 2024 · Avoid high pockets in suction piping, which can trap air. Keep all pipe and fitting connections tight in suction vacuum conditions to prevent air from getting into the pump. 6. Ensure the Piping Arrangement Does Not Cause Strain on the Pump Casing. Pumps should never support the suction or discharge piping.

WebD6.3 Basic design criteria used Peak flow per dwelling is taken from the DCG as 0.05 litres per second. Minimum storage requirement is 160L/dwelling or 1 hour of peak flow (Developments over 500 dwellings). Pump flow rate is at least half the incoming peak design flow rate which must achieve a flow velocity in the WebUse steps 1-3 and the following chart to calculate TDH from tables A & B below.
