Section 2: Recycled Wastewater Demand & Supply Recycling Treated Municipal Wastewater for Industrial Water Use shops, and facilities for electronic and computer production, electroplating, and other metal product fabrications. Sand and gravel operations located away from major rivers rely on ground water sources, Figure 2.3.

Section 2: Recycled Wastewater Demand & Supply Recycling Treated Municipal Wastewater for Industrial Water Use WWTPs. Larger WWTPs are defined in this study as WWTPs with permitted capacities greater than or equal to 1 mgd and smaller WWTPs have permitted capacities less than 1 mgd. The permitted capacity is the capacity defined in the National Pollutant Discharge Elimination (NPDES) Permit, and typically is the design average wet weather flow. The largest six WWTPs in the state treat over 60% of the state’s wastewater, as represented by the plant flow ranges of 10- 50 mgd and greater than 50 mgd in Figure 2.5. Many smaller WWTPs, with permitted capacities less than 1 mgd (not included in Figure 2.5), discharge intermittently and use of annual average data can be misleading. An estimated range of annual average flows for smaller WWTPs is assumed in this study to be 75% of the permitted capacity. Given a combined design capacity of 100 mgd for the 517 WWTPs with permitted capacities less than Figure 2.5. 2005 Annual Average Flows for WWTPs with Permitted Capacities >1 mgd in Minnesota Combined Annual Average Flow, mgd 1 mgd, approximately 75 mgd of treated wastewater supply could be available from smaller facilities. Table 2.3 summarizes the capacity and historic state treated wastewater supply, based on the MPCA Discharge Monitoring Report database (MPCA, 2005). 210 180 150 120 90 60 30 0 22 Source: MPCA, 2005 Table 2.3.
