Waste water is water whose properties have changed due to use by households, trade and industry (waste water) and water that flows away from built-up and paved areas and is collected for transport (rainwater).
For reasons of environmental protection, this waste water needs to be cleaned. Due to the size and topographical location of the Konz association of municipalities, a large network of pipes and several wastewater treatment plants must be operated. The cleaned waste water is fed back into the natural waters. In order to be able to fulfill this purpose, considerable investments were also required in the sewage sector in the past, so that constant improvements could be made to the existing biological sewage treatment plants, pumping stations and the sewage system.
The residential areas in the VG Konz are today very good examples of new ways of sewage disposal through the use and infiltration of rainwater within the residential areas - e.g. through infiltration systems.
The Saarmündung large-scale sewage treatment plant is a model for the most modern technology in the sense of promoting the cleanliness of water and environmental protection.

* EGW = population equivalent
The population equivalent serves as a reference value for the dirt load in water management. It can be related to the biochemical oxygen demand (BOD5), chemical oxygen demand (COD), nitrogen, phosphorus, total organic carbon, suspended solids or water consumption. In each case, it indicates the inhabitant equivalent of the daily amounts of these substances or consumption in wastewater from industry, commerce, agriculture, etc.
The following values are used as population equivalents in Germany:
- Water consumption 180 ℓ/d
- BOD5 60 g/d
- COD 120 g/d
- TOC 45 g/d
- Suspended solids 70 g/d
- Kjeldahl nitrogen (total N without nitrate and nitrite) 11 g/d
- Phosphorus (total-P) 1.8 g/d
