Pump hire specialist, Sykes Pumps, is helping the University of Chichester to maintain high standards of health & safety and sanitation during building works on campus thanks to an overpumping installation during a sewer diversion.

The University of Chichester is developing a new Engineering & Technology Park constructed by Galliford Try as part of the first phase of the project and the groundworks for the scheme include a sewer diversion on a live student campus, requiring a safety critical over pump while a section of the existing sewer main is replaced.

Sykes Pumps has provided two, 8” electric submersible pumps, located in two manholes at the site. The overpumping operation has been designed to take the flow from the manholes to a section of the main 80 metres away in each location, enabling the section of main in between to be removed.

Two Super Wispaset 200 super silenced 8” diesel pumps have also been provided for use as standby equipment if the level of flow exceeds the capabilities of the submersibles. The company has also provided two fuel tanks a ‘Y-piece’ and 12 inch hose to ensure that the flow can be managed if both the submersible and diesel pumps are deployed.

Explains Steve Henty from Sykes Pumps; “The section of main involved in this project is both a sewer and a rainwater overflow. The overpumping solution with the submersible pumps has been designed for normal flow rates but if there is heavy rainfall, the additional flow needs to be managed, which is why we have also commissioned the diesel pumps.

“This part of the waste water infrastructure serves around a quarter of properties in Bognor Regis as well as the University’s campus so a safe, efficient and flexible solution was essential.”

Sykes Pumps will provide weekly maintenance and servicing of the pumps on site as part of the pump hire contract to ensure that the equipment is performing well at all times. Installation of the new sewer section is expected to take around four weeks with further phases of ground works and additional overpumping requirements to follow.
