Methods of Assessment of Technical State and Residual Resource of Pipelines of the Moscow Water Supply and Sewerage Networks

Summary

The goal of investigation of water supply and sewerage systems of Moscow conducted by the Center of technical diagnostics of MGUP Mosvodokanal is the assessment of technical state of networks and development of recommendations for their further operation, reconstruction and relaying. Methods of the complex diagnostics of steel pipelines of water supply network in manifolds, pumping stations’ piping, underground pipelines laid in soil and steel pipelines of pressure sewerage network have been developed. When determining the time of possible safety operation of pipelines of water supply and sewerage networks, these methods make it possible to take into account all types of the most intensive influences contributing mainly to formation of stressed-deformation state that improves technical validity and reliability of results obtained.
