Description:

A major challenge for the society in the twenty-first century will be design, rehabilitation, replacement, and optimal management of drinking water distribution systems. A recent survey conducted by the USEPA found that $138B will be needed to maintain and replace existing drinking water systems over the next 20 years. It is estimated that $77B of this expenditure will be dedicated to repairing and rehabilitating pipelines. Given the cost and disruption caused by replacing distribution system pipe using conventional open trench technology, utilities are beginning to increase the application of rehabilitation or trenchless replacement technologies to extend the life of existing pipes. This paper presents cost models and representative costs that can be used by utility managers to estimate rehabilitation and replacement costs for distribution system pipelines. It should be noted that these cost models and representative costs are intended to be used for comparing costs between various rehabilitation/replacement technologies and not for construction cost estimates.
