10 years since the first Overflow screens Type PAS installed in Spain.
The Overflow screen that Hidrostank manufactures and markets, consists of a 5 or 6 mm perforated grid with diameters of 300 mm or grid 500 mm and effective lengths up to 6 meters. Cleaning is done through water jet generated by a pump that pushes water from the storm itself. The system allows it can be installed both in existing works and new projects, as it can be introduced disassembled and assembled inside. Its simplicity also do all maintenance focuses on the pump that properly placed under a lid, prevents the entry of personnel into the sewage installation, minimizing costs and risks of the operator.

Those first references installed in Huesca and Lugo, were followed bt those installed in Avila, Zaragoza, Cantabria, Ciudad Real, Gipuzkoa, Bizkaia, Asturias, Valencia, Fuengirola, Santiago, Orense … Later more projects were executed in Avila, Lugo , Fuengirola and Gipuzkoa, as a result of the confidence of operators in the simplicity and efficiency of the system.

In the next edition of Pollutec 2016 in Lyon to be held between November 29 and December 2, Hidrostank will present these experiences. The HIDROSTANK Technical Office is at your disposal to study possible implementations of screens both new construction and existing spillways.
