Trough the use of sustainable materials like aluminium, stainless steel and HDPE, we managed to lower the weight of the KOP overflow well substantially.
With this overflow well it is possible to manage the water on the upstream side. With the aluminium stoplogs it is possible to do this in steps of just 50mm, to obtain the right water level. With the weir it is possible to obtain the waterlevel even with millimeter accuracy. The unused stoplogs are stored within the frame itself, on top of the overflow frame.
The well is equipped with an lockable hatch cover, this prevents vandalism and theft because the stoplogs can only be removed with an open cover. The well has an HDPE outfall, for connection to an pipe.
