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.

Products & Tools

Report Reviews Quantitative Tools to Determine Wastewater Soil Treatment Unit Performance
The research (DEC1R06) summarizes available literature on best practices and tools for soil treatment unit (STU) design and performance. It describes STU performance based on data and information from the literature and discusses available modeling tools for constituent modeling.
Report Helps Aid in the Design and Management of Onsite Wastewater Systems
This research (No. 04DEC1) characterizes the composition of modern single residential source onsite raw wastewater and primary treated effluent to aid in the design and management of onsite wastewater systems.
Guidance Now Available for Establishing Successful Responsible Management Entities
New resources provide guidance for successfully establishing and running organizations that manage decentralized wastewater systems -- Responsible Management Entities.
Report Provides Guidance on Modeling Onsite Wastewater Systems
A WERF report gives planners and regulators guidance in developing and using models to evaluate watershed-scale water quality scenarios associated with decentralized or onsite wastewater systems. It includes resources for each step of the planning process, and explains modeling philosophy, model selection, model sensitivity analysis and calibration and other concepts.
