The £318,000 contract from Mowlem Engineering Projects (who are working for Anglian Water) will be competed in March 2001.
Hidrostal gained the contract based on the low expected whole life costs of the equipment.
The inlet pumping station accepts raw sewage from Lowestoft.
Three Hidrostal 400mm bearing frame pumps, together with three 400mm immersible pumps will be installed, each being fitted with two speed motors.
Each pump unit is situated over a 1250 GRP Prerotation basin, which provides the correct geometry for Hidrostal's Prerostal System.
The pumps will efficiently handle variable raw sewage inflow rates, from 200 litres per second to 2,750 litres per second.
In both cases the pumps have good solids handling capabilities, allowing solids of up to 180 mm in diameter to pass through the pump.
The hydraulic end of the pump has a separate liner, which is externally adjustable to allow clearances between the impeller and liner to be maintained at the optimum, thus restoring pump efficiency.
The final stage of the pumping station involves the transfer, via the foul pumps, of the screened and degritted sewage to the treatment works.
Three Hidrostal 200mm close-coupled bearing frame pumps with 90KW motors, will each pump 190 litres of effluent per second at 28m head.
Two pumps, used in tandem, are run with a variable speed inverter drive to pump up to the maximum output of 380 L/s.
A third pump acts as a standby, running at fixed speed.
Three more Hidrostal bearing frame pumps will also deal separately with effluent from the Birds Eye plant.
These pumps can transfer 42 litres of effluent per second in winter and 84 L/s in summer at a total head of 42m.
The pumps will either work individually or as a pair, depending on the throughput required.
