The Goswick site comprised of three 2m x2m flapvalves with a 315DN fish friendly flap valve attachment. Similar in design to that of Beal their primary function was to allow additional time for migration to occur without compromising the larger flood defence door. These fish friendly flap valves are made from our signature HDPE material which has a low theft value, small carbon material footprint and features on the Environment Agency’s sustainable materials list. This material is UV stable and robust increasing product longevity and reducing maintenance and chance of failure.


Beal consisted of one flap- valve with a fish friendly float flap on the front. The total size was 2.5m x 1.4m with a 300DN fish friendly flap mounted on the front. Our float system has been installed over 100 times since its creation with no recorded losses or failures and allows an optimal and adjustable level period where fish and eel can pass through. Each float and fish friendly flap is set at the appropriate level at the design stage to the required catchment levels.

After Ross


Ross, an SSSI, is our 15th site involving the installation of our reset float fish friendly system, an innovative and unique ACE design, manufactured specifically to address tidal applications. Tidal levels are more extreme than catchment levels thus making the float system unfeasible in some cases. The reset system addresses this with doors designed to open, close and reset themselves using the local tide cycle. These doors require no electricity and no complicated settings, the levels can be adjusted easily at any time.
