Predictive Foul Pumping


Water utilities, foul pumping station operators and waste water treatment works operators are facing continued fines for combined sewer overflow (CSO) discharges. StormHarvester allows for a significant reduction in incidence of combined sewer overflows by activating pumps and lowering levels in pumping stations/treatment plants prior to predicted rainfall.

StormHarvester also acts to close the CSO outfall discharge until all available capacity within the network is occupied.

Installing StormHarvester technology has been shown to reduce instances of combined sewer overflows by up to 80% in certain applications.

 

Case Studies

Pumping Station

Installing StormHarvester technology into the pumping station allows the chamber drain down prior to heavy rainfall. Also, by installing a StormHarvester valve onto the CSO discharge pipe the system can make intelligent decisions based on the expected incoming volume and the current available volume. This ensures that all available capacity within the network is occupied prior to activating a CSO discharge. Utilising this additional capacity provides an additional 50m³ holding volume within the chamber. This is estimated to reduce the occurrence of overflow by 80% in this instance.

Predictive Foul Pumping

Combined Sewer Overflows (CSOs) discharge untreated human sewage and waste-water when the sewerage system is overloaded. CSOs act as discharge valves in our sewerage systems, discharging untreated sewage and wastewater when the systems experiences periods of intense rainfall. By linking foul pumping stations and CSO discharges to a highly accurate short term rainfall runoff prediction algorithm StormHarvester can significantly reduce the instances of CSO discharges and reduce associated pollution and fines.
