On the need for revising the Code of Practice CP 32.13330.2018 «Sewerage. Pipelines and wastewater treatment plants» regarding the design of systems for the disposal and treatment of surface runoff from settlements

Summary

The regulatory framework for the design of systems for the disposal and treatment of surface runoff from the territory of settlements and industrial sites is discussed, in particular, the practice of applying the Code of Practice CP 32.13330.2018 «Sewerage. Pipelines and wastewater treatment plants. SNiP 2.04.03-85», enforced by the order of the RF Ministry of Construction of June 26, 2019. Structural changes of the regulatory document are considered, as well as the most common problems that design organizations and the state authorities of project expertise have to face while applying separate provisions in designing engineering structures for disposal and treatment of surface runoff from settlements. A list of the main paragraphs of CP 32.13330.2018 that require revision with the respective comments is presented.

Key words

Overview of the main amendments to the Code of Practice CP 32.13330.2018 «Sewerage. Pipelines and wastewater treatment plants» in terms of designing the systems for the disposal and treatment of surface runoff introduced in 2021

Summary

An overview of the main changes in the design of the systems for the disposal and treatment of surface runoff (rain, melt water) in the current set of rules – CP 32.13330.2018 «SNiP 2.04.03-85 Sewerage. Pipelines and wastewater treatment plants», developed in 2021 by the specialists of the Research Institute of Building Physics of the Russian Academy of Architecture and Building Sciences and a number of other organizations is presented. It is noted that the purpose of amending the current regulatory document is, in particular, harmonization of its provisions with the articles of the environmental legislation that came into force on January 1, 2019 and the new regulatory legal acts of the Government of the Russian Federation that provide for the transition to the principles of technological regulation of discharges in accordance with the technological indicators of the best available technologies. An overview of the most significant changes in CP 32.13330.2018 on the organization and calculation of the systems for the disposal and treatment of surface runoff is given.
