Normally, W&WW acts an advisor/consultant to planners, designers and users of pumping stations - from determining station capacity and selecting appropriate pumps to designing the pumping stations themselves.
W&WW is often asked to assist in analyses involving complex systems.
In those instances, our services can include calculation of hydraulic transients and system losses, optimization of pump-start methods, determination of requisite sump volumes, and so forth.
We are pleased to note that pumping stations designed with our recommendations have proved to be the most cost-effective solutions to a wide range of pumping problems faced by our customers.
