Project summary

Edit project overview to modify the project summary.

The project aims were to improve the aesthetics, water quality and biodiversity of the Platt Brook in Sheldon, Birmingham. The focus of the project was a section of the brook flowing through public land surrounded by high density housing.

Before the project, the brook was much neglected and suffered from silt build up, flytipping and pollution from misconnections and other sewer misuse.

During the restoration works silt was removed and its banks were pulled back to recreate a more natural river channel. It is hoped that the scheme will help the brook to self-cleanse and re-oxygenate, providing much needed urban habitat for wildlife and making the brook more accessible for people.

The project was delivered in 2013.

Since the end of the project the brook has been adopted by a community based WatersideCare group -

This project was delivered by the Birmingham Brooks Partnership and is a sister project to the Short Heath Brook project -

Engagement with local community leading to adoption by WatersideCare group.

Monitoring surveys and results

Edit project overview to modify the Monitoring survey and results.

Water quality monitoring is showing improvements in dissolved oxygen since the restoration work - see DO chart below.

Invertebrate monitoring undertaken in Spring 2012 before works commenced gave a very low BWMP score of 7/200. Biological sampling will be repeated in Spring/Summer 2014.

Changes in public opinion of the brook prior to and after the restoration scheme have also been recorded - see survey results below.

Reasons for river restoration

Mitigation of a pressure
Physico-chemical This watercourse has been subject to sources of urban diffuse pollution such as from misconnections and fly-tipping.
Other reasons for the project The project aimed to improve the look of and access to the watercourse for the benefit of the local community.


Structural measures
Bank/bed modifications Restoring gravel bed
Floodplain / River corridor
Planform / Channel pattern Meandering channel
Other Removal of accumulated debris and silt.
