method of sewer net segmentation and equivalenting

Summary

The design procedure of evaluating a most important index of the municipal sewer net reliability, i.e. relative amount of raw sewage spills resulting from the failure of separate sewer sections is suggested. The design procedure is using a typical characteristic of the system, i.e. its tree-type structure, and lies in the formal substitution of the sewer net for one dummy equivalent pipeline with the reliability parameters that are evaluated with the use of the known rates of failure and rehabilitation of the original (existing) sewer elements. The design procedure is simple and can be used directly by the companies that are operating municipal sewers.
