The project has been operating for 6 years and annually provides 1.1 to 1.2 billion gallons of potable water. This water supplements the 2 billion gallons of ground water pumped by the City. Challenges The primary challenges once operations began were related to the aesthics of the new water supply. The new mixed supply was harder and had a different taste and odor. Savage and Burnsville staffs worked together on several collaborative solutions to solve these issues. Comunication, patience and cooperation were key in solving these issues. The water quality complaints related to the initial issues have virtually been eliminated in both communities. Project Benefits The benefits include: • Reuse of 1.1 billion gallons of water annually • Reduction of 1.1 billion gallons of groundwater pumping and rebounding water levels in the Jordan Aquifer • Viable/sustainable long term source of water for the communities What may help other Communities? It can be done if communities are willing to work together, trust each other and collaborate. However, this type of partnership and success can't occur without state and agency help. Partnerships and Incentives This project would not have been possible without collaboration of Kraemer Mining and Materials, State of Minnesota, MDH, DNR and Cities of Savage and Burnsville. Below is the cost participation in the project: • State of Minnesota $5.5 Million • Kraemer Mining and Materials $3.0 Million • City of Savage $2.0 Million • City of Burnsville $3.5 Million • Total SWTP Capital Cost $14.0 million Community Commitment to Sustainability/Water Supply Security/Collaboration/Etc. The potable use of 1.1 billion gallons of previously discarded quarry water has resulted in rebounding water levels in the Jordan Aquifer locally, and will help ensure sustainability of the water supply for Savage and Burnsville. Lessons Learned • Mixing of surface and groundwater is complicated and upfront investment in pilot results will reduce issues • Understand potential operational issues of connected system, such as impacts to chlorine levels • Proactive education of Public, Council and City Staff on issues such as: - Potential changes in water aesthetics (taste, odor and hardness etc.) - Water is "safe" exceeds all standards Awards and Recognitions 2009 City Engineers of Minnesota Project of the Year - Honorable Mention 2009 Environmental Initiative Award COMMUNITY HIGHLIGHTS WATER SUPPLY MASTER PLAN- Draft June 2015
