By the basic technical solutions GOST 70953-2023 is a new tool for improving the quality of wastewater treatment facilities projects

Summary

The problems that arise while designing wastewater treatment facilities are described. The goals and objectives are given of developing GOST 70953-2023 «Wastewater treatment facilities. Construction and reconstruction. Basic technical solutions. Requirements for the development, structure and content in order to ensure the optimal capital costs and operational performance», that will come into force in 2024. The fundamentals of the concept of this standard, its basic definitions, and advantages in relation to the practice of designing wastewater treatment facilities that prevailed prior to the standardization are outlined. A brief summary of the main sections of GOST is given, in particular, the requirements for the composition of the main technical solutions, the report on their development and the approvals package.

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.
