EPA’s WMOST is a publicly available tool that can be used by state and local managers to screen a wide-range of options for cost-effective management of water resources. It supports a broader integrated watershed management (IWM) approach by allowing the user to simultaneously consider stormwater, drinking water, wastewater and land conservation management practices. Users can select from three versions of WMOST based on their specific management needs. The first version focuses on management of base and peak flows, the second adds a flooding module to assess costs associated with peak flows, and the third includes a water quality module. WMOST aids in evaluating the environmental and economic costs, benefits, trade-offs and co-benefits of various management options, and can facilitate the evaluation of low impact development and green infrastructure management options that are suitable for projects using State Revolving Funds.

Webinar participants will be introduced to the tool and its functions, and how it has been applied in two case studies. First, the Maryland Department of Environment is using WMOST version 3 to identify the most cost-effective suite of stormwater management practices for meeting the management goals of a typical community in their state. Second, a consortium of communities, regional development commissions, and non-governmental and watershed organizations in the upper Taunton River watershed in Massachusetts is using WMOST version 3 to determine the most cost-effective options to meet water quality goals (such as TMDLs), water quantity targets (maintaining base flows and water supplies), reducing flooding and impacts of Combined Sewer Overflows, and supporting land conservation goals under both current and future growth and climate scenarios.
