Stadhampton Mill Bypass Channel (Completed Date: Apr 2023)

Working with the River Thame Conservation Trust, FiveRivers designed a 120m engineered bypass channel on the Chalgrove River to allow for fish passage. We used energy dissipation calculations to ensure our designs worked for fish passage.

Durleigh Wetlands (Completed Date: Jan 2020)

FiveRivers were contracted by Wessex Water to design & build, two multi-benefit wetlands to improve the quality of water entering the drinking water reservoir, whilst significantly enhancing wildlife and biodiversity. The scheme involved excavating two wetlands on the same site. A naturalised wetland and an engineered wetland.

River Restoration on the Misbourne (Completed Date: Nov 2020)

The aim of this River Restoration project was the reconnection of the River Misbourne to its former paleo channel in the centre of the floodplain and restoration of the existing river channel for a total length of 1.14 km. The chalk stream is currently failing to meet Good Ecological Status (GES) under the Water Framework Directive (WFD). Affinity Water (AW) commissioned this project.
