Switch over to the technologic regulation of effluent discharges from municipal wastewater treatment facilities: ten years track record and recommendations after the adoption of the complete package of regulatory legal acts

Summary

On behalf of the participants in the process, a description of the concept of technological regulation of wastewater discharges from settlements, the development and adoption of legislative acts for the switch over to the new system is given. The paper dwells upon the adoption of the final regulatory legal act (Government Decree of September 2020 No. 1430), completing the development of a legislative framework designed to put an end on the use of fishery maximum permissible concentrations as wastewater discharge standards. Explanations are given on the relationship between the status of the provisions of the updated information and technical reference book ITS 10-2015 and the specified resolution in different applications. Recommendations are given for municipal wastewater treatment facilities and engineering companies on priority actions in the preparation and drawing up of applications for integrated environmental permits and design specifications and estimates according to the new regulations. Attention is drawn to the fact that switching over to a new regulation system requires assigning a category to a water body (performed by Rosvodresursy); otherwise the application of the process parameters established by the Government of the Russian Federation is impossible. The specific features of designing treatment facilities in the new regulation system are noted.

A modern system of engineering, technology, and environmental regulation of wastewater treatment facilities: results of 15 years of work

Summary

Transformation of the systems of engineering and environmental regulation of wastewater treatment facilities that has been on the way extremely lively over the past 15 years in this area, aiming to provide a comprehensive view of the work progress; the significance and interrelations of the developed documents; the reasons for the decisions taken and unresolved problems are considered. The main events in reforming the regulation systems are described in chronological order, from the transition from SNiP 2.04.03-85 to CP 32.13330-2012/2018, then to the development of the information and technical reference book ITS 10, and then to the family of the national standards dedicated to the life cycle of wastewater treatment facilities: GOST R 70953-2023 (main technical solutions), GOST R 72113-2025 (commissioning), GOST R 72005-2025 (technological regulations), GOST 25150 (terms and definitions). The following key issues addressed in regulating the life cycle of wastewater treatment facilities: basis of design; front-end engineering design (key technical solutions); basic data for the process engineering; process solutions; calculation algorithms; and streamlining the branch terminology are considered. The final section outlines numerous unresolved issues in regulating wastewater treatment facilities in both engineering and environmental areas.
