Essex Rivers Hub

Bourne Brook is classified as poor for phosphates. Extensive sampling has showed that the majority of the length of the river is suffering from increased phosphate levels, indicating that phosphate loading is sustained across the whole water body. One of the larger sources of phosphate input is likely to be the local sewage treatment works. It is also suspected that there is intermittent point source discharge from other sectors. Higher phosphate levels are likely to be the cause of this water body failing for invertebrates.


Work with the water company to introduce phosphate stripping in at least one of the sewage treatment works along this waterbody.
