Diverting A Sewer With A Temporary Pumping Station

Sometimes, a pumping station can be the perfect solution to for a temporary sewer diversion. Moduquip were involved in a project where we managed the design, approvals, installation, and commissioning of a Thames Water sewer diversion pumping station.

The system was designed to temporarily re-direct a main sewer whilst construction works were carried out at the existing sewer location. Due to the application and the space constraints, no allowance could be made for 24h emergency storage therefore reliability was key. The following are some ways that technology was used to minimise the risk of plant failure;

• The pumps self-cleaned the pipework and sump if a build-up of solids was detected

• The pump rate automatically fluctuated based on the incoming flow

• The pumps would self-reverse and clear if early signs of a blockage was detected

• A 24h remote monitoring system managed the pumping station at all times

Whilst the design and construction was challenging due to space constraints, the system was signed off by Thames Water following commissioning. The pumping station operated for 18 months and not a single blockage was reported!
