European experience in upgrading sewers
Summary
About 15 years ago a project of upgrading the sewer system of the Usedom Island (Germany) was launched. Since the island is a health resort the incoming wastewater in sewers has been characterized by seasonal variations: in summer the amount of wastewater increases approximately twice, whereas in winter the amount of wastewater is low; however of more aggressive quality. From economic considerations pressure sewers were chosen. The optimum pressure in the sewers even during high season is maintained by Wilo pumping units. Reliable and continuous operation of the pumps is provided by the use of Wilo – EMUport solid particle separation system.
