the latest techniques with world-class wastewater network expertise
site-specific, viable solutions to the client's appointed contractor
Our international client operates the wastewater network and treatment plants that serve a population of over one million people. When the inlet screens to a critical wastewater pumping station started to experience repeated hydraulic and mechanical problems, the clients’ appointed contractor turned to the experts at WRc to conduct a detailed investigation and recommend site-specific solutions.
Wastewater pumping stations are the workhorses of the wastewater system, often needing to manage large ranges of flow and inlet composition. Screens are usually fitted prior to most pump assemblies with the aim of removing most of the debris that would otherwise damage or block the pumps downstream. Considering the varying load and composition to which the screens are subjected, it is unsurprising that certain types of screens need regular maintenance in order to keep performing to their specified design duty.
Using the latest Computational Fluid Dynamics (CFD) techniques combined with world-class wastewater network expertise, the team were able to investigate conditions in the upstream network, flow dynamics within the chamber, and the performance of the screens themselves to propose viable solutions to the client.
