Feasibility Assessment & Guidance for Stormwater Reuse
Working with Metropolitan Council Environmental Services, Camp Dresser & McKee (CDM) evaluated the feasibility of using stormwater runoff for irrigation and other purposes that traditionally rely on potable water. Effective implementation of stormwater reuse practices can lower demands on drinking water supplies and reduce impacts from aquifer decline, while simultaneously reducing mass loading of pollutants to surface waters. The project includes an analysis of factors that influence the feasibility assessment, scoping and implementation of stormwater reuse projects; an analysis of the requirements, challenges, and benefits of stormwater reuse systems; and the development of stormwater collection, storage, treatment and distribution component options.
The Stormwater Reuse Guide provides technical guidance for communities that is specifically tailored to the Minnesota hydrologic cycle, cold climate/deicing issues and local permitting processes. Guidelines and conceptual plans provide tools to assess the feasibility of, and to scope and implement, stormwater reuse projects. This project complements and supports existing stormwater guidance manuals, such as the Minnesota Stormwater Manual.
$400,000 is appropriated in fiscal year 2011 from the clean water fund, pursuant to Minnesota Statutes, section 114D.50, to the Metropolitan Council to fund Metropolitan Council water supply planning activities under section 473.1565, for projects that include, but are not limited to, protection of the Seminary Fen and Valley Branch Trout Stream; lessening groundwater vulnerability by mapping glacial aquifers; creation of a comprehensive map of known groundwater contaminant plumes; and the design of plans that can be used by communities for reusing storm water. By January 15, 2011, the council shall report to the chairs and ranking minority members of the legislative committees and divisions that make recommendations for appropriations from the clean water fund on the outcomes of the council's water supply planning activities. This appropriation is onetime and available until expended.
The proposed outcome is for communities to have better guidance for evaluating and adopting stormwater best management practices that meet stormwater infrastructure goals while simultaneously benefiting water supply planning through reduction in potable demand.
Outcomes will be reported at project completion.
