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.
A cooperative study was conducted by the U.S. Geological Survey (USGS), the Metropolitan Council, and the Minnesota Department of Health to assess groundwater and surface-water interactions in lakes in the northeast Twin Cities Metropolitan Area (TCMA), including White Bear Lake. An important product of the study was the creation of a groundwater-flow model focused on the northeast TCMA. The groundwater flow model is available for future use to assess the effects of groundwater withdrawals on lake levels as well as to describe other groundwater and surface-water interactions.
The State Fiscal Year 2014-2015 Clean Water Fund appropriation identified the northeast metro as an area where potential solutions are needed to address emerging water supply issues. The Metropolitan Council, in conjunction with S.E.H. consultants, evaluated water supply approaches to serve the northeastern part of the Twin Cities metropolitan area. A subregional study areas was selected based on the indication of potential problems with the long-term sustainability of current water supplies, as well as expressed interest by community stakeholders.
The State Fiscal Year 2014-2015 Clean Water Fund appropriation identified the northeast metro as an area where potential solutions are needed to address emerging water supply issues. Three projects are underway to identify the advantages and disadvantages of combining water supply systems, using new water supply sources such as treated water from Saint Paul Regional Water Services or raw water from the Mississippi or St. Croix rivers, and optimizing groundwater pumping to protect water levels in White Bear Lake and other lakes across the northeast metro.
The Minnesota DNR and the Minnesota Forest Resources Council work with forest landowners, managers and loggers to implement a set of voluntary sustainable forest management guidelines that include water quality best management practices (BMPs) to ensure sustainable habitat, clean water, and productive forest soils, all contributing to healthy watersheds. This project will monitor the implementation of these forest management guidelines and BMPs on forested watersheds in MN.
Minnesota’s use of groundwater has increased over the last two decades. An increasing reliance on groundwater may not be a sustainable path for continued economic growth and development. The DNR is establishing three pilot groundwater management areas (GWMA) to help improve groundwater appropriation decisions and help groundwater users better understand and plan for future groundwater needs associated with economic development.
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.
In 2005, Metropolitan Council was directed to carry out regional water supply planning activities under Minnesota Statutes, section 473.1565. Working closely with the region's many water supply stakeholders and under the guidance of a metropolitan area water supply advisory committee, Metropolitan Council developed and adopted a metropolitan area master water supply plan (master plan) in 2010. The plan provides a framework for water supply planning and identifies actions needed to achieve the goal of ensuring sustainable water supplies across the region.
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. This program began by defining opportunities for water conservation for three businesses through the dedicated resources of three MnTAP interns. The interns analyzed water conservation opportunities through full time work on site over the summers of 2014 and 2015.
This project will establish a groundwater monitoring network in the 11 county metropolitan area. The network will provide information about aquifer characteristics and natural water trends by monitoring healthy aquifers (non-stressed systems). The project will also develop an automated system that captures groundwater level and water use data. This system will enhance evaluation of changes in aquifers that are stressed by pumping from existing wells.
This project will create a high accuracy elevation dataset - critical for effectively planning and implementing water quality projects - for the state of Minnesota using LiDAR (Light Detection and Ranging) and geospatial mapping technologies. Although some areas of the state have been mapped previously, many counties remain unmapped or have insufficient or inadequate data. This multi-year project, to be completed in 2012, is a collaborative effort of Minnesota's Digital Elevation Committee and partners with county surveyors to ensure accuracy with ground-truthing.
The DNR has been charged by the legislature to develop rules that protect and manage the Mississippi River Corridor Critical Area (MRCCA) for natural resource, economic development, transportation, historic preservation, and other values. This project engages stakeholder groups in a public process to balance regulatory protections with local flexibility and control.
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.
The Metropolitan Council, in conjunction with HDR Engineering, Inc. consultants, will evaluate a variety of approaches to develop sustainable water supplies across the metro area. Subregional study areas are being selected where multiple communities face potential problems with the long-term sustainability of current water supplies, and where community stakeholders have expressed interest in learning more about sustainable water supply options.
In 2005, Metropolitan Council was directed to carry out regional water supply planning activities under Minnesota Statutes, section 473.1565. Working closely with the region's many water supply stakeholders and under the guidance of both policy and a technical water supply advisory committees, Metropolitan Council supports regional groundwater planning and analysis in order to respond to emerging regional water supply issues and achieve sustainable water supplies.
State law charges the Metropolitan Council (Council) with developing and maintaining a base of technical information needed for sound water supply decisions (Minnesota Statutes 473.1565). The Council’s primary tool to provide this information is the Metro Model 2, a regional groundwater model capable of predicting the impacts of planned water demand on aquifers and connected lakes and streams. The Metro Model 2 is a modern and comprehensive groundwater model of the Twin Cities area, but it is currently out-of-date.
The Metropolitan Council, in conjunction with CDM Smith and HKGi consultants, reorganized and expanded the water conservation tools on the water supply planning pages of the Metropolitan Council’s website. The revised toolbox was organized into an online, web-based guide format. These tools are supplemented with fact sheets and case studies that serve to educate and provide useful information to support water conservation programs and activities.
The Metropolitan Council (Council) implemented a water efficiency grant pilot program effective September 30, 2015 to June 30, 2017. Grants were awarded on a competitive basis to municipalities that manage municipal water systems. The Council provided 75% of the program cost; the municipality provided the remaining 25%. Grants were made available in amounts with a minimum of $2,000 and a maximum of $50,000. Grantees were required to provide estimated water savings achieved through this program for Clean Water Land & Legacy Amendment reporting purposes.
