Wastewater collection

Wastewater collection normally takes place by means of gravity from domestic households and the industry where the wastewater is led to pumping stations and pumped into the wastewater treatment plants.

There are two main systems for the wastewater collection: collection systems with combined sewers and collection systems with separated sewers for rainwater and wastewater. Combined sewers transport the wastewater from private households and companies as well as rainwater in the same pipe. Many new collection systems provide separate sewers for wastewater and rainwater.

Rainwater is collected in sewers and led either directly to the pumping stations or to rainwater storage tanks where it at a later stage is mixed with the wastewater. As the amount of rainwater is unpredictable it may be necessary to store the rainwater either in basins around the country side or in stormwater tanks inside the wastewater treatment plants. In this way it is easier to control the flow of the rainwater as it is mixed with the wastewater when the plant has the capacity to clean the rainwater.

For wastewater collection, AVK offers gate valves, check valves, slide- & knife gate valves, air valves, couplings, adaptors, repair clamps, tapping saddles, fittings, and accessories.
