We are committed to reducing our water usage on the Cranfield campus by 30% in 2017 from a 2009 baseline year.

Our own sewage treatment works on Cranfield campus operates within an environmental permit which restricts the levels of ammonia, biological oxygen demand (BOD) and suspended solids within discharged effluent. We are aiming to reduce the pollutant load of effluent discharges from our sewage works to 50% below individual permitted levels by 2020.

Water use

We have installed over 50 water meters across the Cranfield campus and have undertaken extensive upgrades to pipework to improve knowledge of water use and identify and repair leaks. These improvements alone have reduced our water use by 13% in 2013/13 from 2008/9 baseline figures.

Love every drop

We have partnered with the Anglian Water ‘Love every drop’ scheme to help us monitor and reduce water usage. We plan to install more water saving devices across the Cranfield campus and also look at options for rainwater harvesting or grey water recycling in the future.

Sewage works

We operate our own sewage works at the Cranfield campus which processes the majority of our wastewater on site. This unique facility is also used by us and partner organisations for teaching and research purposes. During 2014 improvements were made to the monitoring, alarm and metering equipment at the sewage works to ensure we remain within consent levels for all effluent discharges.

Chicheley Brook

Flowing through the Cranfield campus is the Chichelely Brook. This waterway provides excellent opportunities to support biodiversity enhancement on campus but is also at risk of pollution incidents due to all drainage from the campus ultimately reaching the brook. As such, we place strict requirements on the waste liquids that can be discharged to our on-site drainage network.
