As water and wastewater water utility owners seek innovative rehabilitation technologies to extend the service life of their assets there is a need to provide accurate performance and cost information on innovative technologies as they come to market. To meet this need, the US Environmental Protection Agency created a field demonstration program to evaluate innovative and emerging technologies to increase the effectiveness of the operation, maintenance, and renewal of aging drinking water distribution and wastewater conveyance systems. This program has resulted in the development of a technology demonstration and evaluation process that evaluates each aspect of pre-installation, installation and post-installation activities in order to provide information that is beneficial to water and wastewater water utility owners, technology manufacturers, and consultants and service providers. To date, two technologies indentified as innovative water rehabilitation techniques have been demonstrated. It is recommended that additional innovative and novel technologies be demonstrated under a similar program in the future to determine their applicability, while providing accurate performance and cost information to water and wastewater utility owners.
