Background:

A development known as ‘Land East of Carterton’ is proposed on a greenfield site in the town of Carterton, Oxfordshire. The proposed development will consist of 800 residential dwellings, 15,000m2 of commercial land, and a school. There is an existing foul sewer network within the developer’s land, which forms part of the Brize Norton Sewage Pumping Station (SPS) catchment. However, it was determined that the existing SPS catchment has insufficient capacity to accept flow from the proposed development. As a result, the new Carterton SPS was designed and constructed to take flows from the development, and pump them to the existing foul sewer network, before gravitating to Carterton STW. As part of this project, a new Real Time Control (RTC) strategy was also implemented, with a new level monitored manhole installed in the downstream network to provide an inhibit to the SPS during surcharged network conditions.

Our Role:

LJR Engineering worked on behalf of the Principal Contractor to provide MEICA project management and technical expertise across the duration of the project. During the tender phase, we provided assistance to the principal contractor, creating the activity schedule and compiling documentation to form part of the tender pack. We worked closely with them to review tender submissions and select the most appropriate. We were also heavily involved in project design, reviewing MEICA design documents and providing feedback to the client and principal designer to ensure all aspects of the installation met asset standards. During construction, LJR Engineering managed all MEICA subcontracted works, working closely with subcontractors and the client to ensure installations were completed to the project specifications and by dates defined within the project programme. As well as leading a full commissioning programme of the new SPS and downstream RTC manhole, we also managed handover for the principal contractor, creating a Site Operating Manual and providing oversight and review of the subcontractors site O&M.
