Urban waste water treatment per province and river basin district
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 10 April 2020:
The figures of 2018 has been added.
The underlying coding of classifications (Regions) used in this table has been adjusted. It is now in line with the standard encoding defined by CBS.
The structure and data of the table have not been adjusted.
When will new figures be published?
New figures on 2019 will be published by March 2021.
