This research explores the feasibility of recovering thermal energy from sewage, and what the state of current technology is for doing so, It is the first step identifying prospects and practical applications of sewage thermal energy use (STEU) by water resource recovery facilities. The research team reviewed over 350 peer-reviewed articles, abstracts, and books on resource recovery and interviewed more than 30 industry leaders. The team gathered experience from 13 North American facilities, six vendors, and multiple international installations to further explain STEU. This report discusses approaches used by faciliites, communities, and utilities around the world; as well as obstacles, tools benefits, and challenges to STEU. Published by WRF. 236 pages.
