This table presents the most significant results of the annual survey Public treatment of urban waste water. The results are presented per province and river basin district (Rijn, Maas, Eems and Schelde) and include:
- number and capacity of the urban waste water treatment plants by type of treatment;
- the volume and concentration of organic matter, nutrients and heavy metals in the waste water running into waste water treatment plants (influent) and the volume of treated waste water (effluent). As of 2017, data on heavy metals are only inventoried for even years.
- the volume and destination of the sludge released, with nutrients and heavy metals. As of 2017, sludge data are only inventoried for even years.
Additional data on urban waste water treatment plants, process technology, energy consumption, generation of energy and sludge dewatering can be accessed on the Dutch version of StatLine.
Data available from: 1981
Status of the figures:
The figures in this table are definitive.
Changes as of 22 April 2024:
The figures of 2022 has been added.
When will new figures be published?
New figures on 2023 will be published by March 2025.
Description topics
- Sewage sludge
- Residue of treated waste water consisting of suspended solids and excess active sludge (biomass). Sewage sludge is measured including water (see Total wet sludge) or as dry solids.
- Wet sewage sludge by destination
- The volume of wet sewage sludge, i.e. including water by destination (processing method).
- Co-incineration at power plants
- Sewage sludge used as a secondary fuel at a power plant.
- Dry solids by destination
- Discharged sewage sludge in kilogrammes of dry solids by destination (processing method). Dry solid is the residue of sewage sludge after evaporation at 105 degrees centigrade.
- Co-incineration at power plants
- Sewage sludge used as a secondary fuel at a power plant.
