Belflor® Water-stop

Do you have too much surface water flowing into the sewage?

Very often, after heavy rain, floods or in case of melting water there may be a stagnation of water or flooding in the canalisation. As a consequence of the bigger water flows, water transportation to the depuration plant as well as to the pumping stations gets more expensive. Our belflor® Waterstop stops surface water hindering its entering into the canalisation, thus saving costs.
