New build product specification

REQUIREMENT

A mistake in an initial survey undertaken by others meant that the gravity connection from a rainwater attenuation tank missed the surface water sewer. We were asked to specify, install and commission a pump set within a pre-cast concrete chamber to pump storm water from the rainwater attenuation tank to the public sewer.

METHOD

• We carried out a site survey and specified the chamber dimensions and access cover.
• We monitored the construction of the concrete chamber during each phase of the build.
• We supplied and installed a twin pump set into the chamber.
• We supplied and installed a kiosk so that the control panel was situated close to the pump station for around the clock access in the event of a breakdown.

RESULT

• By liaising closely with the main contractor throughout the build we ensured that the chamber was constructed to our specifications. This simplified installation and reduced costs.
• We specified single phase pumps so allow retrofitting of battery backup power should the end client require it.
• By locating the control panels close to the pumping station maintenance will be easier and safer.
• We will offer the end client a comprehensive maintenance. Regular maintenance is essential when pumping water from uncontrolled sources such as surface water.

FOCUS ON:

RAINWATER ATTENUATION

Rainwater attenuation is required when a storm event could discharge water into the sewer system at flow rates higher than limits set by the local water authority.

Storm water is diverted to balance ponds, holding tanks or attenuation crates. Pumping stations are then employed to discharge the water into the sewer at a controlled rate.

Our expert team can specify pumping stations to suit any site and water authority requirements.
