Rye Brook Reed Bed Design

The Head Ranger to be heard.

Minutes:

The Head Ranger was heard regarding Rye Brook Reed Bed Design and the following points were made.

 

·         The Head Ranger noted that the design proposal dated back to the November 2014 study of riverfly on the Common which had identified poor water quality. Mass water sampling had been conducted in Mach 2017 which had identified high levels of phosphate near the Ashtead Estate Office. As a result, the City was looking to install a reed bed filtration system designed by the South East Rivers Trust. A Lidar map had been created which had identified some challenges such as buried infrastructure.

 

·         The Head Ranger continued, noting that a longer system would cost £230k and up to £300k if contingency was included. It was likely that the project would require a partnership approach to secure grant funding e.g. with Thames Water and/or the Environment Agency.
