Urban Water Solutions have extensive experience in the design and optimisation of Pressure Sewer Systems across the world and presented a session at the Water NZ Modelling Symposium on ‘Optimising the Design & Operation of Pressure Sewer Systems’.
Pressure sewer systems have been in use since the early 1970s and are now an established alternative to gravity sewers for difficult to sewer areas. By using time-based pump operation rules, it is possible to control the timing of pump operations. This allows the modulation of flows in the system and reduces the peak flows to the discharge point. Modulating the flow by controlling how many pumps will operate simultaneously throughout the day, results in smaller pipe diameters across the system and reduces the detention time of the sewage in the PSS pipe network.
