Mono played a major part in waste water treatment facilities for Dover Harbour Board.  Following the recent development of the amenity block, the customer required a pumping system to handle the sewage from five toilets, five sinks and four showers.  Minimal maintenance and maximum efficiency were key factors in the decision to install the Grifter Packaged Pumping System. 

With low speed, low running costs, low power and low wear, the Grifter can be fully operational within 2 hours.  The system consists of 2 (duty and standby) Grifter sewage pumps, complete with all necessary suction and delivery pipework to connect to the rising main.   The pumps are housed above the sewage in an insulated glassfibre reinforced plastic kiosk, assembled in-house and delivered to site ready to install.  A suction pipe into the sump lifts the sewage for maceration and then pumps the wastewater to the main sewer.

The system uses small bore pipes which reduces the risk of septicity and incorporates easily visible display lamps indicating pump function and sump level conditions, which give advance warning of any problems and reduce the risk of subsequent damage.
