Core Tasks and Services

In addition to wastewater treatment, the AZV operates and maintains the sewer network and pumping stations to ensure the smooth transport of wastewater to the treatment plant. A breakdown service is available to fix problems in the sewer network.
Sustainability and Environmental Protection
The AZV Oyten/Ottersberg attaches great importance to sustainability and environmental protection. The goal is to protect groundwater and soil from contamination and to minimize the environmental impact of wastewater. The sludge produced during sewage sludge treatment is thermally recycled. The digester gas obtained in the digestion tower is used in two microturbines as a regenerative energy source for electricity and heat generation.
The AZV also appeals to citizens to actively contribute to environmental protection by not throwing waste into the toilet, not pouring toxic substances and paint residues into the sink, using washing and cleaning agents sparingly, and consuming as little water as possible.
Future Orientation
The AZV Oyten/Ottersberg sees itself as a modern service provider that ensures orderly wastewater disposal around the clock. Continuous investments in infrastructure and the employment of qualified employees ensure a high quality standard. The AZV strives to make wastewater disposal sustainable and to continuously improve the protection of people and the environment.
