Project Overview

We have conducted a flood study of Wimbledon Park Lake, it was found that it no longer meets safety standards required by the Reservoir Act 1975. We are carrying out statutory improvement works in the interest of reservoir safety.  

Ward and Burke Construction Ltd have been commissioned by us to undertake the design, planning and construction of modification and improvement works to the existing Wimbledon Park Reservoir dam. These works require the upgrade of the existing spillway, embankment modifications and construction of an additional auxiliary spillway to accommodate safe passage of the flood events.

The scheme will also include additional improvement works including the deculverting and river restoration of Wimbledon Park Brook in the park.

A planning application for the scheme has been submitted to us.
