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.
The Metropolitan Council and City of Saint Paul cooperated on a rainwater harvesting and reuse system in downtown Saint Paul. Rainwater from the northern half (2 acres) of the roof at the new Metro Transit Green Line Operations and Maintenance Facility (OMF) is captured using a modified version of the existing OMF rainwater collection system. The existing collection system was re-designed to convey rainwater to the new Lowertown Ballpark, home of the Saint Paul Saints, where uses include ball field irrigation and toilet flushing.
The Metropolitan Council, in conjunction with CDM Smith consultants, undertook a project to collect and disseminate data regarding water costs and conservation programs in the seven-county metropolitan area, including:
• Evaluating all water rate structures of the communities in the seven-county metro area. The information on rates by community is correlated with community per capita values, peaking ratios, and other water use characteristics.
• Evaluating all water conservation programs in the communities in the seven-county metro area.
