A research centre near Cambridge had a dilapidated sewage treatment plant, which was originally built in the 1940s and over the years had undergone a variety of upgrades.

As the research centre has become more commercial and a variety of clients share the existing and new built facilities it was decided to make a significant upgrade to the treatment plant.

The centre went out to tender early in 2006 for the upgrade of the plant and Alpheus were successful in winning this with an alternative bid to the specification at £560K.

Alpheus designed the upgrade using lamella separators. In addition to the lamella separators the project included a new inlet screen, new influent and effluent monitoring, demolition of the existing primary and secondary sedimentation tanks which the lamellas replaced, demolition of an old sludge tank and the supply of a new tank.

As well as being a sizable contract, there was the complexity involved in carrying out all the work whilst maintaining the ability to treat effluent throughout.

As the project progressed Alpheus secured additional work, including replacing a satellite pump station, providing a washwater booster set, and installing covers and odour control for the existing balance tank. These additions increased the project value to £770K.
