Methods ofimproving the reliability of water distribution network operation

Summary

The conditions of providing for the integrity of the water distribution network for maximum possible period are considered. On basis of analyzing the mathematical expression developed with the use of mass service system device the conditions of ensuring water distribution network integrity are determined. It is established from the experience of water distribution network operation that pipe material and repair time are critical for reliability improvement. Ductile iron pipes with interior cement-sand coating and PVC pipes as better meet this requirement.

Key words

water supply network , integrity , water supply system reliability , pipe material , repair time , failure rate
