Ordinance on self-monitoring of sewage systems
The regulation for the self- monitoring of wastewater systems (Self-Monitoring Regulation Abwasser - SüwVO Abw) is a legal regulation of the state of North Rhine-Westphalia . It was announced on November 8, 2013 in the Law and Ordinance Gazette for the State of North Rhine-Westphalia (edition 33/2013) and came into force on November 9, 2013. It replaces § 61a of the State Water Act NRW and the self-monitoring Regulation channel of 16 January 1995 (GV. NRW. 64) and adjusts the self-monitoring of sewerage and discharge of waste water from sewage systems in the mixing and separation system , and self-monitoring of private sewers . In other federal states there are comparable regulations under the title Self- Control Ordinance .
Emergence
On the basis of Section 61 (2) of the State Water Act of North Rhine-Westphalia , the Waste Water Self-Monitoring Ordinance was passed on October 17, 2013 as a new state ordinance on the monitoring of public and private waste water systems by the North Rhine-Westphalia state parliament . It came into force the day after the announcement in the Law and Ordinance Gazette for the State of North Rhine-Westphalia, November 9, 2013.

Self-monitoring of sewer systems and discharges of wastewater from sewer systems in the mixed system and in the separate system
Part 1 of the ordinance regulates the self-monitoring of the structural and operational condition and the functionality of sewer networks for public sewage disposal as well as of paved commercial areas larger than three hectares as well as the monitoring of the discharge of sewage from relief structures of these sewer networks.
The ordinance obliges the operator of a sewer system to monitor its condition and functionality and to set up instructions for self- monitoring . The scope of the examination and the frequency of the examination can be found in Appendix 1 of the ordinance.
Self-monitoring of private sewers
Part 2 of the ordinance applies to all privately operated underground sewage pipes with the exception of pipes for the sole discharge of rainwater and pipes that are laid in tight protective pipes in such a way that escaping sewage is captured and detected ( leakage detection ). These sewer pipes are to be built and operated in such a way that the requirements for sewage disposal are complied with and may only be built, operated and maintained in accordance with the generally recognized rules of technology (here: DIN 1986 Part 30 and DIN EN 1610). The operators are obliged to monitor the condition and functionality of the lines themselves. After installation or significant changes, the lines must be checked by experts in accordance with the generally recognized rules of technology for their condition and functionality. An expert within the meaning of the regulation is someone who has been recognized as such by the relevant North Rhine-Westphalian Chamber of Crafts , Chamber of Industry and Commerce or Chamber of Engineers Construction .
Furthermore, existing sewers in water protection areas that were built before January 1, 1965 (for wastewater from industry and trade: before January 1, 1990) must be checked for their condition and functionality for the first time by December 31, 2015 at the latest, all other sewers in water protection areas must be tested for the first time by December 31, 2020 at the latest. Existing wastewater pipes for conveying industrial or commercial wastewater, for which requirements are specified in an appendix to the wastewater ordinance, must be checked for condition and functionality for the first time by 31 December 2020 at the latest. For the testing of private sewers outside of water protection areas, no nationwide deadline for the initial testing was specified. A repeat test must be carried out 30 years after the initial test.
The results of the initial monitoring are to be documented in a certificate; any damage that has been identified is to be repaired at short notice or within ten years, depending on the type of damage. In the case of minor damage, a repair is sufficient until the next repeat test.
