Treatment facilities, often

The sewer system of a country house is a rather complex multi -stage design consisting of the internal and outer part. The installation of cleaning of the inner sewage wastewater consist of several parts — these are wastewater receivers and pipes. These structures are responsible for the exporting of drains to the outer part of the sewer system of the country house. The external, or outer part, sends drains to local treatment facilities, often used special pumping stations with special hydraulic characteristics.
