11 The second purpose is to produce documentation that can be used by state and local agencies, particularly the Metropolitan Council, for future local and regional planning purposes. As a result of projected population increases and land use changes in Lino Lakes, the Metropolitan Council estimates that sanitary sewer flows will increase approximately 54 percent between 2010 and 2040. This Sanitary Sewer Plan outlines the locations in which the Metropolitan Council can expect to see increased wastewater flows, allowing the Council to determine if capacity upgrades will be required in the region. This plan was developed in conjunction with the Land Use plan. Chapter 9 - Water Supply Plan This chapter describes Lino Lakes’ plan to meet its existing and future water supply needs in a safe and dependable manner. First, it evaluates the existing Lino Lakes water system to identify any needs or deficiencies. Second, it identifies the future water system needed for the city’s growth through full build out based on the city’s population projections described in Chapter 1 and the 2040 and Full Build Land Use Plans described in Chapter 3 of this plan. The Ramsey County District Court issued a ruling on August 30, 2017 that the Minnesota Department of Natural Resources (DNR) allowed over pumping of the groundwater aquifer in the region of White Bear Lake. The judge ordered the DNR to review groundwater appropriation permits within five miles of the lake and to enforce a residential lawn watering ban when the lake water level drops below 923.5 feet above sea level. On September 26, 2017, the DNR issued a news release stating that it will appeal the court’s ruling. The DNR contends that restricting permits within five miles of the lake will halt important development, and that the watering ban will impose an undue burden on 500,000 White Bear Lake area residents. A portion of southeastern Lino Lakes falls within five miles of White Bear Lake so the city is closely following developments in this case and will coordinate with the DNR to ensure that it is complying with regional and state guidelines. Development in District 4 is proposed to be temporarily supplied by White Bear Township along an 8-inch water line along the southern border of Lino lakes. This may be an issue depending on the outcome of the lawsuit. The City of Lino Lakes will review and adjust its Water Capital Improvement Plan (see Appendix C) as definitive conclusions become available and will continue water conservation and efficiency programs to reduce its consumption throughout this process. This plan recommends that the city consider two water treatment plants, one in the southern region of the city (Water Treatment Plant No. 1) and one in the northern region of the city (Water Treatment Plant No. 2). The city is currently considering the future location of Water Treatment Plant No. 1 to be near the future water tower site along Birch Street. The recommended location for Water Treatment Plant No. 2 is within the potential future well field, located in the northern region of the city. Both water treatment facilities would be designed for the removal of iron and manganese. The city would update the feasibility study before designing a water treatment facility.
