Leakage is one of our customers’ highest priorities. Across the company we have seen a 10% reduction over the last five year; in the Nottingham region we saw one of our largest year on year reductions in the volume of water lost.
We recognise the value of protecting the environment and the benefits this brings to our communities. This year we provided 39 grants to local farms and landowners to help the protect raw water quality and nine 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, in the Nottinghamshire region our performance was broadly steady.
Across the company we have seen a year on year deterioration in sewer flooding, in part driven by the wet weather. In the Nottingham region we also saw a deterioration of both internal and external flooding incidents.
During the year we have also worked closely with local authorities to tackle flooding risks from multiple sources (sewers, rivers, highway drainage etc). We completed the following projects this year:
- A complex, multi-agency scheme delivering biodiversity and flood risk benefits to 160 properties through blue/green infrastructure with Nottingham City Council;
- In Mansfield we worked with Nottingham City Council to reduced flooding risk to seven properties through innovative use of an old subway to store surface water;
- An award winning scheme in Nottingham working with the City Council to incorporate highway drainage to reduce flooding risk to 44 properties; and
- A complex scheme with Nottinghamshire County Council to relieve sewer flooding risk at 13 properties as well as the risk of highway flooding.
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.
