Last year, during our phase two consultation, we shared our early design principles and emerging design for the relocation project.
As part of this final phase of consultation, we want to hear your views on our detailed design proposals for the new facility and surrounding site area, proposed mitigation measures to minimise impacts on local communities, and the opportunities identified for environmental enhancement beyond the site boundary.
Building a modern, low carbon waste water treatment facility
The design of the facility will contribute to Anglian Water’s goal to reach net zero carbon emissions by 2030 by reducing energy consumption and contributing towards the circular economy. The new facility will significantly reduce carbon emissions compared to the existing Cambridge facility and will be operationally net zero and energy neutral.
We will also target a 70 per cent reduction in “capital” or “embedded” carbon during the construction phase compared to a 2010 baseline by adopting sustainable construction techniques. Read more in our Carbon Paper.
Helping Cambridge to grow sustainably
The relocation provides an opportunity to develop a modern, forward-looking water recycling facility, using the latest technology and operational practices. This means we can continue to serve the growing population of Greater Cambridge for years to come, in a more sustainable and resilient way.
Maximising public value and supporting the circular economy
The efficient and effective recycling and re-use of waste water, is core to public health and the circular economy. The design of the facility further supports a circular economy by:
- more effectively recycling nutrients, in the form of phosphorous and ammonia, found in waste
- treating the biosolids captured as part of the wastewater treatment process, creating an
enhanced soil conditioner for use by local agriculture,
- generating biogas which, when processed and exported into the local gas network, will be
used to heat the homes of the local community as a renewable fuel source
Improving storm resilience and the quality of the recycled water we return to the River Cam
Storm overflows play a vital role in our combined waste water network systems as they work like pressure release valves to protect homes and businesses from flooding during periods of extreme rainfall. The Environment Agency (EA) issues permits for our storm overflows.
The new facility will provide greater resilience and improved storm management, meaning storm overflows and Combined Sewer Overflows (CSOs) are far less likely to occur. This means that, as Greater Cambridge continues to grow, the facility will be able to treat a greater volume of storm flows to a higher standard than would be the case at today’s facility.
The new facility is being designed to reduce concentration in final treated effluent discharges of phosphorus, ammonia, total suspended solids and biological oxygen demand (BOD), compared to the existing Cambridge facility. This means that when the new facility starts to operate, water quality in the River Cam will improve.
