We were recently asked to design and commission a sewage pumping station for a new housing estate in Amersham where the water level was 200mm lower than the drainage system.
This project needed to be completed quickly, with the customer asking us to have the foul water pumping station installed within 3 weeks of contacting us.
We were made aware that this new housing estate had a steep, single-tracked road and so additional care should be taken when delivering the pumping station to site.
