Further significant improvement to relief structure thanks to a fifth HUBER Storm Screen ROTAMAT® RoK2: stormwater tank with overflow in Wendelstein

Since 2008, the ZV zur Abwasserbeseitigung im unteren Schwarzachtal (Lower Schwarzach Valley Sewage Treatment Association) has been retrofitting existing relief structures with screening systems to separate floating and coarse materials. These retrofits contribute significantly to greatly improving the discharge quality of rainwater from the combined sewer system into the receiving water.

Installation of a screening plant at the Röthenbacher Straße stormwater tank with overflow

In the stormwater tank with overflow at Röthenbacher Straße in Wendelstein, just outside Nuremberg, a screening plant had to be installed in front of an existing overflow sill. The system had to be dimensioned so that the entire discharge volume of 2,234 l/s could be reliably treated with a required screen aperture of 6 mm. The very limited permissible backwater levels during system operation also had to be taken into account for dimensioning.

HUBER Storm Screen ROTAMAT^® RoK2 meets all requirements

The HUBER Storm Screen ROTAMAT® RoK2, size 700, was able to meet all these requirements without restriction.

Decision in favour of proven technology

Based on the positive operational, maintenance and separation performance experiences gained from the previous four screen installations, the decision was made to purchase another HUBER Storm Screen ROTAMAT® RoK2. 

HUBER SE would like to thank the client, the Lower Schwarzach Valley Sewage Treatment Association, the head of the wastewater treatment plant, Mr Heiling, and the engineering firm Christofori und Partner from Heilsbronn, which was responsible for planning, tendering and construction supervision, for their trust and excellent, constructive and smooth cooperation.
