The final solution comprised of two separate gravity collection systems (total length: 1.4km) with two submersible pumping stations discharging via two separate rising mains (total length: 3.1km) into the existing Great Ellingham network delivered in AMP5.
The pumping stations were a subject to a full planning application, which involved an environmental screening opinion, ecological and archaeological studies.
The scheme required several consents from LLFA and highway due to number of ditch crossings, pumping station locations and road closures.
The key to the project success was to work closely with all internal and external stakeholders to define the solution during risk and value intervention process. The solution, completed on time, provided a £1.7m saving against AW’s business plan.
The final solution outperformed the client’s embodied carbon reduction of 56.7% against baseline (from 697 tCO2 to 299.57tCO2) and operational carbon reduction of 63.6% (from 14 TCO2/pa to 5.1tCO2/pa).
