Controversial issues of improving the regulatory framework governing the design, construction and operation of gravity wastewater disposal systems

Summary

In recent decades, the integrity health of sewer pipelines has been deteriorating in the cities of the Russian Federation. The increasing rate of wear and tear and unsatisfactory integrity health of a considerable number of sewers, the need to ensure the reliability and environmental safety of the pipelines, and limited material resources for their rehabilitation and renewal in the context of housing and utilities reform require a scientifically proved approach to solve these problems. Choosing the technologies of pipeline rehabilitation in order to improve their reliability requires improving the regulatory documents (in particular, CP 32.13330.2018 «Sewerage. External networks and structures») that regulate the requirements for newly built and reconstructed wastewater disposal systems. The federal legislation establishes the minimum threshold requirements for buildings and structures (including the networks and engineering infrastructures in them), as well as for the design, construction, operation and utilization. CP 32.13330.2018, that specifies the requirements for wastewater disposal systems of populated areas newly built or under reconstruction; for the external networks and permanent structures for domestic, surface (rain and melt) and industrial wastewater compositionally alike, considers the requirements of the federal legislation not to the fullest extent. Based on the analysis of the relevant federal laws and provisions of CP 32.13330.2018, the need to establish basic requirements for sewer pipelines is substantiated, i. e. pressurization, steady-state stability, estimated transported wastewater flow pass and maintainability.
