Selwood was approached by Severn Trent Water to provide an over pumping solution from Ladybower Reservoir to the Yorkshire Water distribution main.This was required because the pumps currently installed were unable to abstract flows when reservoir levels dropped.
The summary
The challenge
- Low reservoir levels
- Fluctuating levels after abstraction starts
- High flows required of 462l/s
- Busy public location
- Overgrown woodland where we were installing our rising main
The solution
We developed a solution through close collaboration with the client and our supply partners. By utilising a floating pontoon, we were able to position our pump units 200m into the reservoir at its deepest point and design the pipework to accommodate both the flex and fluctuating water levels.
