Essex Rivers Hub

Find solutions to pollution from sewage treatment works and create inchannel habitats.

This stretch of the river is very pleasant. The banks consists of typical vegetation for this habitat which is allowed to flourish with little management and some inchannel vegetation present also.

However there is an outlet from the sewage treatment plant which discharges into the channel when useage is high (usually after heavy rain) to relieve pressure from the works. The discharge is very diluted but a local resident has concerns that the discharge is having an impact on the rivers ecology.

A possible solution to this is for the outlet to flow through a reed bed before it enters the main channel which will allow any pollutants to be filtered out.

The channel is also very straight with little variation so installing some woody debris would help to create inchannel habitats. Woody debris will create variations in flow and change the river structure to a more natural shape. This will create a variety of habitats and help to increase biodiversity.

WFD overall status objective

To achieve Good ecological status by 2027

Project type

Water quality, habitat creation.

Benefiting species and/or habitats

Improved water quality and reduced input from the sewage treatment works would reduce the levels of phosphate in the water which would help to reduce problems with algae blooms and increased vegetation growth that can choke the channel. Woody debris will create more habitats and help to increase biodiversity.
