Figure 2.15. Metro Area Industrial Water Demand, 2005 Building Materials Chemical Products Electronic Products Food Products Health Care Laundry Medical Products Metal Products Other Paper/Packaging Photo/Printed Products Power/Steam/AC Public Facilities Transportation Source: Met Council, 2005 1.0 1.7 1.6 1.4 1.2 2.1 2.6 3.4 5.5 5.9 6.4 Section 2: Recycled Wastewater Demand & Supply Recycling Treated Municipal Wastewater for Industrial Water Use 7.5 0.0 2.0 4.0 6.0 8.0 10.0 12.0 14.0 16.0 Water Use (mgd) The total Twin Cities metro area industrial demand is estimated to be 75 mgd. This estimate is based on an analysis of both databases to determine a reasonable estimate of the industrial demand supplied by water utilities. Industries that supply their own water through MDNR appropriations permits used approximately 30 mgd in 2004. The Twin Cities metro area water utilities used 350 mgd in 2004. Assuming that 13% of potable water supply customers are industries, another 45 mgd of industrial demand is supplied by water utilities. 2.4 WWTP Focus – Empire and Rosemount WWTP Inventories This study inventoried the industries in proximity to major WWTPs in the seven-county Twin Cities metro area. This section provides the inventory for the Met Council’s Empire & Rosemount WWTPs, located in the Lower Mississippi River watershed. Appendix II-1 provides the inventories for the other WWTPs. The Empire WWTP was recently expanded from 9 mgd to 24 mgd and the 1.3 mgd Rosemount WWTP will be phased out with wastewater from its service area treated at the Empire WWTP. The Empire WWTP, which currently discharges to the Vermillion River, will have a new discharge to the Mississippi River in the vicinity of the one currently used by the Rosemount WWTP. Figure 2.16 identifies the industries near each plant and Table 2.7 lists those within a 5-mile radius of each plant. The outfall for the Empire WWTP to the Mississippi River is also shown on Figure 2.16. The list of industries is restricted to the radius around each plant, but could be broadened to include industries along the outfall. As described previously in the Lower Mississippi River Watershed Inventory section, Flint Hills Resources is the high water demand industry using ground water in the area, withdrawing over 6 mgd in 2004. The industry with the next largest water use is Aggregate Industries, with a demand of 1.1 mgd, supplied by surface water at a facility near the Mississippi River. Another Aggregate Industries facility is located closer to the Empire WWTP and uses a ground water supply of 0.4 mgd. The industry with the largest water demand near the Empire WWTP is Marigold Foods, which uses 0.32 mgd of ground water supplied by its own well field. Another food product industry, Kemps, has a demand of 0.25 mgd. The other industries in the area have a combined demand of 0.32 mgd. Metropolitan Council Environmental Services 27 10.6 14.7
