Our Objective

WE&RF will improve the capacity of public and private agencies to respond to the increasing complexities of, and expanding need for, decentralized wastewater and stormwater systems, as part of an integrated water management approach. WE&RF will achieve this primarily through support of research and development projects that help communities, engineers, regulators, and others address critical knowledge and information gaps in decentralized systems.
