Project Update – River Restoration Design & Build at Barn Meadows and Pondswicks Meadows, Old Amersham

FiveRivers are currently on site delivering the construction phase of a design and build contract with Affinity Water, on the River Misbourne at Barn Meadows and Pondwicks Meadows, Old Amersham. This project forms part of Affinity Water’s River Restoration Programme which aims to restore natural chalk stream processes, creating suitable habitat for fish and macroinvertebrates, while also ensuring the rare chalk stream habitat is resilient to a range of flow conditions.

Since last year, our teams worked on designing morphological improvements for the River Misbourne at Barn Meadow and Pondwicks Meadow. This included: carrying out desk-based assessments, topographic surveys, morphological and ecological surveys, extensive hydraulic modelling, outline designs and detailed designs. Our design team also worked with Affinity Water on community engagement events to share the proposed improvements and gather feedback from local residents and the general public.

Our construction team are now on-site undertaking gravel augmentation, the creation of a low flow channel, berm creation, and bank regrading, plus the creation of backwaters at Pondwicks Meadows, for a 3-week period. Last week our founder, Jason Lovering, visited site along with colleagues from FiveRiversand Affinity Water to follow the progress of works. Currently, the River Misbourne is only achieving ‘moderate ecological status’ under the Water Framework Directive (WFD); once completed, the project is expected to help contribute towards the River Misbourne achieving ‘good ecological status’ under the WFD.
