Leakage is one of our customers’ highest priorities. Across the company we have seen a 10% reduction over the last five years; in the Warwickshire region we saw a small improvement from last year in the volume of water lost.
Across the company we have seen a year on year deterioration in sewer flooding, in part driven by the wet weather. In the Warwickshire region we the number of internal and external flooding incidents remained broadly stable year on year.
This region is one of our most rural and a major focus of our environmental protection programmes which aims to protect raw water quality and delivery wider benefits to our communities. This year we provided 92 grants to local farms and landowners to help the protect raw water quality and three further grants to projects through our Boost for Biodiversity fund.
Sometimes sewage can escape from our underground pipes, or assets such as pumping stations, which is harmful to the environment. As a company we have reduced the number of pollution incidents to one of the lowest levels ever, this included a year on year improvement in our Warwickshire region.
This year we completed two innovative sewage treatment schemes in Warwickshire at our Rugby and Fincham (Coventry) sites to allow both works treat future growth in the catchment without building new processes on site.
- At Rugby we were the first company in the UK to use the BioMagTM technology to improve the treatment process and allow the current works to treat the sewage of up to 15,000 additional people
- In Finham we integrated a new element to existing treatment processes that has the effect of adding an additional 33% to our biological treatment stage.
This allows the works to treat the equivalent of another 56,000 peoples’ sewage each day.
As part of our commitment to be a socially purposeful company we have helped customers through our Big Difference support scheme, helped customers during an incident through our Priority Services Register and educated local school children about water efficiency and sewer misuse.
