It is a pleasure to serve under your chairmanship, Ms Elliott. For my constituents, this issue is of significant local concern. In fact, last year, the very first visit I made as an MP was to see with my own eyes the impact of a sewage discharge at Latimer Park in my constituency.
Chesham and Amersham is home to two of the nation’s chalk streams: the River Chess and the River Misbourne. They are globally rare and locally precious, but despite their ecological significance, in 2020 and 2021 the River Chess saw a total of 175 discharges from Thames Water’s treatment works in Chesham—one of the worst figures in the country.
My constituents clearly share my disgust, as more than 1,000 of them signed the petition to ban this damaging practice, and I want to give voice to their concerns. Fortunately, I have been assured that something is about to change at a local level. This summer I met Thames Water, which outlined its plans to expand the capacity of the Chesham sewage treatment works by 40% to prevent future sewage discharges. However, as we know, storm overflows do not only take place due to a lack of capacity. Discharges frequently occur during particularly rainy periods when the rainwater run-off makes its way into the sewerage system through leaky pipes and loose manhole covers. Thames Water is looking to counter that in my constituency, and is undertaking a project to replace or reseal 750 manhole covers. I welcome that investment, and I look forward to seeing the results of its efforts, which it assures me will be completed by the end of 2023. I know I will not be the only one locally keeping a close eye on whether it meets that target.
If we are to protect our country’s rivers, similar action must be taken across the country, and quickly. The Government have assured us that such improvements will take place, but I am concerned that, under current plans, a portion of the price of the works will be paid by the public in the form of increasing water bills. The discharges occur in large part as a result of years of underinvestment and neglect by water companies. They must be held to account for the failure to maintain essential infrastructure to a functional standard. They should pay to fix it.
