Waste water treatment

hoelschertechnic-gorator® GmbH & Co. KG plans, delivers and assembles all equipment for municipal and industrial waste water treatment plants.

We provide complete treatment plants in close collaboration with planning agencies, sewage boards, municipalities and industry. Existing plants can be modernised or expanded. We use system components that we have made ourselves and work together with competent partners to deliver effective and economical waste water solutions.

Alongside product quality, preventative servicing is a prerequisite for long-lasting, disruption-free operation. Regular maintenance intervals are also essential. And if the worst comes to the worst, any damaged parts can be replaced. These are all jobs that our service staff will take care of.
