Working with the Metropolitan Council, the University of Minnesota - Minnesota Technical Assistance Program (MnTAP) is investigating the opportunity for water conservation by private industrial water users across the Twin Cities metropolitan region. Private industrial water users are defined as industries that use private wells for their water supply. This work is determining factors that encourage or create barriers for implementation of identified industrial water conservation opportunities.
On behalf of the Metropolitan Council, the Minnesota Geological Survey collected information and conducted an assessment of the hydraulic properties and chemistry of selected aquifers in the metro area. This project greatly improves the accessibility of existing data, which were previously available only in scattered paper reports. A robust database of groundwater age, aquifer hydraulic conductivity and groundwater chemistry data was developed to make the information easily accessible to water resource managers.
The Twin Cities metropolitan area has a rich history and connection with its waters. In an effort to keep surface waters clean, a wide variety of stormwater practices have been developed and installed throughout the metro in recent years. Many of these, such as rain gardens and infiltration basins and trenches, are intended to reduce the total runoff volume by infiltrating stormwater. Six to seven aquifers underlie the metro area and provide residents with drinking water.
The Metropolitan Council, in conjunction with the University of Minnesota Technical Assistance Program (MnTAP), are exploring opportunities for water conservation by businesses in the eleven county metropolitan area. Opportunities for water conservation will be defined for three businesses through the dedicated resources of three MnTAP interns. The interns will analyze water conservation opportunities through full time work on site over the summers of 2014 and 2015.
The University of Minnesota Technical Assistance Program (MnTAP) identified opportunities for industrial water users in the North and East Metro Groundwater Management Area (N&E Metro GWMA) to reduce their water consumption as part of the Department of Natural Resources strategies under the GWMA plan. The source of water in this delineated region is almost exclusively groundwater. Several approaches were used for this effort in order to reach, inform, and interact with a broad range of industrial users.
On behalf of the Metropolitan Council, the Minnesota Geological Survey evaluated the vulnerability of glacial aquifers in the Twin Cities metropolitan area. The project improved upon previous vulnerability assessments by incorporating a substantial amount of new aquifer property information and blending methods previously used by the Minnesota Departments of Health and Natural Resources. The result is a consistent vulnerability assessment across the metropolitan area based on the most up-to-date information available.
The Twin Cities area is host to a nationally renowned system of regional parks that provides numerous outdoor recreational opportunities for the public while preserving green space for wildlife habitat. The Metropolitan Council is using this appropriation to partially finance the acquisition of approximately 195 acres to be added to existing metropolitan regional parks, with priority given to lands with shoreland, lands that provide important natural resource connections, and lands containing unique natural resources.
The Metropolitan Council, in conjunction with the University of Minnesota, is evaluating outdoor water use in the Twin Cities metro region - a subject which has come under the spotlight recently due to concerns related to water quality and quantity issues. In the Twin Cities, 20% of all treated drinking water is used outdoors, with a majority of this being used on lawns and landscapes. The goal of this proposal is to reduce water use in the home landscape by conducting assessments, research, and demonstration around the smart use of irrigation.
