Royal HaskoningDHV has been commissioned by the SES Water to undertake a feasibility assessment of making alterations to the west weir at Shepley Mill.
The need for the Project
In-channel water control structures, such as weirs, are common on many UK rivers.
Aims and Objectives
SES Water with assistance from Royal HaskoningDHV have undertaken a detailed feasibility assessment which considers alterations to the west weir at Shepley Mill.
Site Location
Shepley Mill is located on the River Wandle (TQ 28278 65594) approximately 0.4 km north of Carshalton and 5 km west of Croydon, within the London Borough of Sutton.
Stage 1 Engineering and Environmental Constraints
A review and validation of existing surveys, data, and reports to inform the other stages and overall outcomes of the feasibility study was initially undertaken during Stage 1 for the project.
Stage 2 Fish Passage : Concept Designs, Solutions and Appraisal
Based on the outcomes of Stage 1 and appropriate fish passage and geomorphology guidelines, a long list of proposed fish passage (and habitat) solutions was derived.
Stage 4 Preferred Fish Passage Solutions and Next Steps
The outcomes of the options appraisals enabled the selection of the preferred fish passage (habitat) solutions which could be taken forward to the next phase of the project.
Overview
The below provides an overview of the key baseline information regarding engineering and environmental constraints associated with the Shepley Mill study area see here which need to be considered in order to identify the most viable fish (habitat)
