Regulations on Water Quality
The legal framework for water management is the Federal Water Act [Wasserhaushaltsgesetz -
WHG]. The WHG applies to waste water generated by various industrial processes. The usage
of surface, coastal, and ground waters requires the approval of the competent authority. Discharges
into water are regulated in the Waste Water Ordinance including its Annexes [Abwasserverordnung,
AbwV]. It specifies the minimum requirements to be stipulated when granting
a permit to discharge waste water from the source categories listed in the Appendices into
receiving water.
Issued by the Federal Government in consent with the Federal States (Länder), these minimum
requirements bind the authority competent for licensing and controlling the discharges. Depending
on the local conditions, more stringent requirements can be established. The minimum
requirements are based on the ‘emission principle’ and the precautionary principle. General
requirements according to the Waste Water Ordinance are covered by the Article 3 listed below:
General requirements
i. unless otherwise stated in the Appendices, a permit to discharge waste water into waterbodies
shall only be granted if the pollutant load at the site of occurrence, based on an examination
of the conditions in each individual case, is kept as low as the use of watersaving
procedures such as washing and cleaning operations, indirect cooling and the use
of low-pollutant feedstocks and auxiliary materials permit
ii. the requirements of this Ordinance must not be met by means of procedures whereby
environmental pollution is transferred to other environmental media such as air or soil,
contrary to state-of-art
iii. requirements specified in the form of concentration levels must not be achieved via dilution,
contrary to state-of-art
iv. if requirements prior to blending are specified, then blending shall be permissible for the
purpose of joint treatment, provided at least the same overall reduction of contaminant
load per parameter is achieved as would be the case via separate compliance with the
relevant requirement
v. if requirements are specified for the site of occurrence of waste water, blending is only
permissible provided these requirements are adhered to
vi. if waste water flows which are subject to differing requirements are discharged jointly,
then the relevant decisive requirement for each parameter shall be determined by means
of alligation
