DE-WWTP - data collection of wastewater treatment plants of Germany (status 2015, metadata)

The waste water treatment data collection for Germany (DE-WWTP) was collected and put together at the UFZ in 2015/2016.

It is based on a query to all German federal states except Hamburg, Berlin and Bremen to provide the location of waste water treatment plants as well as the yearly load of nutrients to the receiving waters. The query was restricted to WWTPs with a population equivalent (PE) smaller then or equal to 2000 (data set 1). This data set was combined with the public available data for WWTPs with PE > 2000 (https://www.eea.europa.eu/data-and-maps/data/waterbase-uwwtd-urban-waste-water-treatment-directive-5, data set 2).
The result (DE-WWTP) is a combination of both data sets containing all German WWTPs for all PE (data set 1 + data set 2).

DE-WWTP contains for most of the records the following information (sometimes only P or only N was reported):
- Name of WWTP
- federal state
- coordinates of effluent
- capacity of WWTP
- PE (population equivalent)
- size class of WWTP according to German law (https://www.gesetze-im-internet.de/abwv/anhang_1.html)
- annual discharged P [kg/year]
- annual discharged N [kg/year]

德国污水处理数据集（DE-WWTP）由亥姆霍兹环境研究中心（UFZ）于2015至2016年间采集并整理完成。

该数据集基于向德国所有联邦州（不含汉堡、柏林、不来梅）发起的调研，旨在获取污水处理厂的地理位置及其向受纳水体排放的营养物质年负荷量。本次调研的对象限定为人口当量（PE）小于等于2000的污水处理厂（数据集1）。随后将该数据集与公开可得的PE＞2000的污水处理厂数据（https://www.eea.europa.eu/data-and-maps/data/waterbase-uwwtd-urban-waste-water-treatment-directive-5，数据集2）进行合并。

最终产出的DE-WWTP数据集由上述两个数据集整合而成，覆盖了所有人口当量等级的德国污水处理厂（数据集1+数据集2）。

DE-WWTP的多数记录包含以下信息（部分记录仅报告了磷（P）或氮（N）的相关数据）：
- 污水处理厂名称
- 所属联邦州
- 排放口坐标
- 污水处理厂处理能力
- 人口当量（PE）
- 依据德国法律划定的污水处理厂规模等级（https://www.gesetze-im-internet.de/abwv/anhang_1.html）
- 年排放磷量 [kg/年]
- 年排放氮量 [kg/年]
