| Milnthorpe Water Treatment Plant |
|
 |
In May 2005 NW Pump and Valve were awarded the contract by Galliford Costain to supply and install the mechanical element in the construction of a brand new waste water treatment plant at Milnthorpe, Cumbria.
The contract is the largest we have undertaken and involved precise timing to deliver mechanical expertise against a very tight installation programme.
Within the scope of the new treatment plant, two secondary rural pumping stations were constructed to deliver collective wastewater to the treatment plant.
|
NW Pump and Valve provided a range of disciplines and hydraulic knowledge to supply and install a variety of mechanical equipment, valves, steel pipework and fittings, pumps, fabrications and on-site welding.

The photographs (above and left) show one of the two sludge storage tanks with steel structures. Each tank is fitted with a bank of nine off 6” decanting pipes and valves, coupled together for removing surface de-cant water. |
 |
Also shown (left) are three horizontal pumps, mounted in series and coupled together using 8” ductile iron pipework and fittings. The pumps transfer the sludge from tank to tank. |
