On calculating the capacity of surface runoff treatment facilities
(to be discussed)

Summary

It was demonstrated that for the most part of the territory of our country in the process of designing treatment facilities for surface runoff from the territories allotted for settlement and first group industrial areas the daily amount of snowmelt runoff is determinative. To calculate the capacity of the accumulating tanks and treatment facilities using the data on the amount of water in snow cover by the beginning of spring snowmelt is suggested. When using the suggested additions to the method of designing surface runoff treatment facilities the capacity of accumulating tanks increases approximately twice; whereas the capacity of treatment facilities is reduced approximately eightfold. The information on the implementation of the suggested approach in designing and constructing treatment facilities receiving surface runoff from the territory of Tarkett factory manufacturing flooring (Otradnyi, Samara Area) is presented.

Calculating the capacity of surface runoff treatment facilities in the context of the environmental legislation reform

Summary

The regulatory documents – federal laws, RF Government Decrees and Environmental Protection Department orders are presented that were brought into force with the purpose of reforming the environmental legislation with regard to the protection of water bodies from wastewater pollution. Their great importance for water users is noted because the adopted regulatory documents determine the relationships between water and wastewater utilities and the customers of the public wastewater disposal systems; regulate the procedure of determining the permissible concentrations of pollutants discharged by water and wastewater utilities into water bodies, the procedure of determining on their basis the permissible pollutant concentrations discharged by the customers; and confirm the basic principles of estimating and charging for the negative impact on the environment including violation of the permissible discharge standards. Special attention is paid to RF Ministry of Natural Resources order No. 339 of July 29, 2014 related to making amendments to «The methods of developing the standards of permissible pollutant and microorganisms discharges to water bodies for water users» (2007). New «Guidelines for designing the systems of collection, removal and treatment of surface runoff from habitable territories, industrial sites, and determining the conditions of its discharge into water bodies» developed by «NII VODGEO»» OJSC in 2014 as a Supplement to Building Code SP 32.13330.2012. «Sewer system. Public utilities. Revised edition of SNiP 2.04.03-85» are discussed. The specific features of calculating the standards for permissible discharges of pollutants applied to the outlets of surface effluents generated on habitable territories and industrial sites are noted. The improved methods of calculating daily melt water amounts removed for treatment and the capacity of the treatment facilities are presented.
