SVVAAB

General description of the company
SVVAAB produces and supplies 143 million m3 high-quality drinking water/year to more than 1.2 million persons in Stockholm and its vicinity. They are operating two water treatment plants located in Norsborg and Lovö, and two wastewater treatment plants located in Henriksdal and Bromma. The company treats 136 million m3 wastewater/year from the Stockholm area from 1.08 million persons of which 316200 are connected to the Bromma WWTP. The company also operates 2241 km of drinking water network, 3027 km sewage water network, 11 water reservoirs, 70 water pumping stations, and 231 sewage pumping stations. 73000 tonnes of sewage sludge/year are produced of which 15700 tonnes/year are produced in the Bromma WWTP. 15.3 million Nm3 biogas/year are produced of which 4.1 million Nm3/year are produced in Bromma. Part of the sewage water network is combined and part of it is separated from the storm water. The company's responsibilities also include water pollution and lake restoration.

The Bromma plant is a conventional activated sludge WWTP with screens (slot distance 3 mm), grit chambers, pre-aeration channels, primary sedimentation tanks, and biological treatment in aeration tanks and secondary sedimentation tanks. As a final process step in the plant, sand filters are installed. They reduce the suspended solids in the effluent to a concentration below 2 mg SS/l. The treated wastewater is discharged into the Baltic Sea.

Stockholm Vatten continuously works to reduce the impact that the organic substances, phosphates, and nitrogen will have on the environment. At least 95 % of the organic content, =98 % of the phosphor, and =50 % of the nitrogen are removed during the purification, thus satisfying the demands of the authorities.

Stockholm Vatten is financed by charges for water and sewage services in Stockholm and nearby Huddinge and is a leading customer and environmentally oriented water and wastewater company that meets the customers' need of water services on the basis of an integrated approach and high ecological standards. Since the hydrological cycle does not recognise any regional or national boundaries, the company is also engaged in cooperation projects with other municipalities.
