Stadtentwässerung Dresden GmbH

The Stadtentwässerung Dresden GmbH (SEDD) is a central player in wastewater disposal and treatment in the state capital Dresden and the surrounding region. As a joint venture of the state capital Dresden (51%) and GELSENWASSER AG (49%), the SEDD combines public responsibility with private efficiency.

The SEDD provides a wide range of services that cover the entire value chain of wastewater disposal:

• Collection and Disposal of Wastewater: Through an extensive sewer network of about 1,850 km in length, wastewater and rainwater from households, businesses, and industry are collected and directed to the treatment plant[3][4][5].
• Wastewater Treatment: At the central treatment plant Dresden-Kaditz, one of the largest East German treatment plants outside Berlin, wastewater is cleaned through mechanical, biological, and chemical processes to be discharged into the Elbe in an environmentally friendly manner[3][4][5].
• Fecal Waste Disposal: The SEDD ensures the disposal of residues from non-drainable pits and small treatment plants[3][4][5].
• Maintenance and Rehabilitation: The expansion, maintenance, and rehabilitation of the sewer network and treatment plants are further central tasks[3][4][5].
• Energy Generation and Environmental Protection: The SEDD focuses on renewable energies and energy efficiency by generating energy from sewage sludge, ground and wastewater heat, hydropower, and solar energy[3].

The SEDD is committed to fulfilling its tasks reliably and within the framework of legal requirements. Expertise, efficient handling of financial resources and technical facilities, as well as a customer-oriented service readiness form the basis of its success. The company acts sustainably and responsibly, often beyond its immediate interests, and is deeply rooted in the region of Dresden and East Saxony[3][4].

The SEDD is strongly committed to environmental protection and resource conservation:
