Description:
This paper presents on-going research work for the USEPA Research Project on “Rehabilitation of Water and Wastewater Systems.” It will compare various renewal methods (i.e. replacement, rehabilitation and repair technologies that are available in the market). The paper discusses the current setup of the water distribution infrastructure and highlights system rehabilitation of water mains. System rehabilitation is the application of infrastructure repair, rehabilitation and replacement technologies in an effort to return functionality to the water distribution system. It further provides considerations and key design parameters for choice of rehabilitation vs. replacement and choice of the right rehabilitation systems and the key criteria for selection of rehabilitation technology. The study classifies the technologies based on industry practice and water industry standards. It aids the utility manager by providing a detailed description, and installation and design standards for a suite of technologies for the rehabilitation of water systems that do not require a full excavation and replacement. A variety of tools and methods can be used to complete the job. The paper discusses the integration of government regulation, standards of practice and available market products for a water utility to address pipeline renewal.
