摘要

A major challenge faced by nearly every utility is how to address its aging underground infrastructure. Sewer pipes are failing from coast to coast as America finds itself on a fast track to replace or renew sewer collection systems. A major driving force is the mandate set forth by state and federal regulators that require utility owners to renew their systems so they are watertight. Today, if a utility uses State Revolving Loan Funds (SRF) to pay for its sewer rehabilitation project, the design must be justified based on life-cycle cost analysis. This requirement is imposed by legislation passed by the U.S. Congress in 2014 known as the Water Resource Reform and Development ACT (WRRDA). Even without the requirement for such an analysis, a responsible utility should perform one to ensure the best value for the rate payer's investment. The days of ground water infiltrating and overloading pipes, pumps and wastewater treatment plants at public expense is now a priority to correct.
