On the reliability of water supply and wastewater collection systems

Summary

Integrity of operation is the most important attribute of the water distribution and wastewater collection networks. However up to now the regulatory documents lack the definition of this notion. By the case studies of the water distribution network operation the great losses that the national economy incurs due to the lack of the integrity indicators in the construction rules and regulations have been demonstrated. It is noted that introducing these indicators will provide for the significant improvements in the design methods and evaluation of the operation of water and wastewater systems. A considerable number of the experts are not ready to change the conventional working arrangements ignoring the Order of the RF Ministry of Regional Development that offers the indicators that take into account the reliability of operation. The RF Ministry of Housing and Public Utilities must display insistence and perseverance in adopting a firm technical policy in relation to this issue.
