Yet another sewage spillage occured in the Chess Valley, this time on the 22nd February. Again, untreated sewage flowed from the Chesham Sewage Treatment Works (CSTW) onto neighbouring land. On this occasion, the volumes were not significant, but are evidence of an on-going problem at the site. The operator of the plant, Thames Water, is aware of the issue and is looking for ways to prevent this reoccurring. The Environment Agency has been informed.

This is one of a number of recent sewage pollution events at this location. We are working with Thames Water and the Environment Agency to avoid these incidents occurring, but they are hapenning far more frequently than anyone would like.

All pollution incidents should first be reported to the Environment Agency Hotline on 0800 80 70 60. In the case of sewer leaks in our area, also contact Thames Water on 0845 9200 800.
