We were asked to design, specify, install and commission two pump stations to remove foul and surface water from pre-cast concrete chambers in the basement of an old accountancy building which was being developed into modern office space. Each pump station would be remotely monitored by a telemetric system within the control panel.
• The main contractor constructed the chambers using stacked pre-cast concrete rings. A standard biscuit with a standard access cover dimensions was installed to seal the chambers.
• It can be more cost effective to install a set of pre-cast concrete rings to form a chamber rather than purchasing a packaged pumping station. The costs of installing pumps within needs to be taken into consideration.
