Analysis of regulatory requirements for shut-off and control valves for drinking water supply networks and world practice

Summary

The problem of the absence in Russia of a specialized industry for the production of materials and equipment for the water supply and wastewater utilities is described. The requirements of domestic and international regulatory documents for shut-off and control valves for drinking water supply, including the methods of control and testing of valves in production, are stated and analyzed. The experience of operating shut-off and control valves in the drinking water distribution networks, including directly buried ones, at the facilities of SUE «Vodokanal of St. Petersburg» is presented. Particular attention is paid to the requirements of SUE «Vodokanal of St. Petersburg» to the shut-off and control valves installed in the municipal water distribution networks. Developing a system of regulatory documents directly for the water and wastewater utilities, and in particular for drinking water supply products, will provide for systematizing the requirements to the product control and testing systems, improving the quality and increasing the life of the utilities.
