Sewage plant Felsberg –
rehabilitation during service

between the 17th and 25th of June 2009 our SIVV certified technical staff rehabilitated the sewage plant of the city of Felsberg, with a surface area of approximately 500m2. What followed was a full-scale concrete rehabilitation of the outlet channel and the complete fabrication and installation of a runway heating system, a pronged sill and a scrum board. What was special about this: the whole building project was executed whilst keeping the plant in-service and without emptying the tank. Due to effective coordination of our special, pump-equipped vehicles, there was no downtime.

Brand new: Clear of ice – in the long run nearly for free

Clearly, a heated scraper runway simplifies the winter operation considerably. What is new about this is that the operating costs of such a heating system are next to nothing because one can dispense with external energy sources. Both pictures show this type of installation; last winter we undertook several extensive tests and the system proved itself superbly.
