Craddock Consulting Engineers In Association with CDM & James Crook 1-1 TM1-Sec1_0707.doc Section 1 Introduction 1.1 Project Vision Conserving Minnesota’s ground water and surface water resources is important to all sectors in the state and is key to the state’s long-term economic development. The economic vitality of Minnesota requires the business sector to grow with the population of the state. While water supply availability is not presently considered a limitation for industrial development in many Minnesota communities, there are numerous areas in the state that have a limited supply of high quality water. Even within the metro area of the Twin Cities, development is now extending to areas with less productive aquifers and future growth will increase competition for a limited water supply. Industries requiring abundant or high quality water could be restricted from locating in some areas unless other water supply options are made known and available to them. One potential supply in these water-short areas is effluent from municipal wastewater treatment plants (WWTPs), also known as reclaimed water. Municipalities may benefit by offering ”water reuse” as an alternative water source to industries and by forging partnerships with industries to promote conservation of a limited potable water supply and improved protection of the state’s water resources. In July 2005, the Metropolitan Council (Met Council) was awarded a $300,000 grant from the Legislative Commission on Minnesota Resources for this project titled, “Recycling Treated Municipal Wastewater for Industrial Water Use.” The timeframe for the project is July 1, 2005 to June 30, 2007. Funding for this project was recommended by the Legislative Commission on Minnesota Resources from the Minnesota Environment and Natural Resources Trust Fund. The Met Council is providing additional funding for the project through in-kind contributions of staff time. In addition, other state agencies such as the Minnesota Pollution Control Agency (MPCA), Minnesota Department of Natural Resources (MDNR) and the Minnesota Department of Health (MDH) are participating via stakeholder meetings and technical review and input. It is estimated that 20% of project funding is from these in-kind contributions of staff time and 80% from the Minnesota Environment and Natural Resources Trust Fund. The guiding goal for this project is to promote the conservation of Minnesota’s ground water and surface water resources by recycling treated municipal wastewater for industrial use. The project is applicable to communities throughout Minnesota. Benefits include: (1) Less ground water aquifer depletion due to one-time use and discharge from surface waters; (2) Lower demand on finite water resources to support business and growth; and (3) Reliable and potentially lower cost water sources for industry in the long-term.
