Section 3 Inventory of Major WWTPs and Potential Industrial Reuse Demands Craddock Consulting Engineers 3-11 In Association with CDM & James Crook WWReuseTM1_Sec 3_final.doc The Agra Resources Coop is within 2 miles of the Albert Lea WWTP. The Austin Utilities power facility location is within 5 miles of the WWTP and could be closer depending on its proximity to the permitted wells. Factors Influencing Potential for Industrial Reuse The majority of the Cedar River watershed is in Ground Water Area 2 of the state, which has a good bedrock aquifer supply and limited water bearing surficial sands and moderate availability of water in the buried sand aquifers. The southern edge of the watershed is part of the karst area of Ground Water Area 3, where ground water supplies are strongly linked to surface supplies. Contamination susceptibility varies over the watershed with a higher potential in the eastern sections and areas of lower susceptibility interspersed with areas rated with highest susceptibility in the mid- and western regions of the watershed. Occasional well interferences have been noted, but the public water supplies have had no problems. The agricultural practices of the area have led to nitrate contamination which could affect the Prairie du Chien-Jordan aquifer as well as surficial aquifers. Agricultural drainage wells have polluted deeper ground water. Des Moines River Industrial Water Use There is little permitted water used for industrial purposes in the Des Moines River watershed. Of the 0.66 mgd used in 2004, the majority was for agricultural processing industries, specifically PM Windom, Worthington Rendering, and the City of Heron Lake. Sand and gravel operations collectively withdrew 0.1 mgd from surface waters in 2004. Table 3.9a and Figure 3.9a summarize the industrial water use for the Des Moines River watershed. There were no water withdrawals related to power generator facilities. In Heron Lake, located southwest of Windom, a 50 million gallon capacity ethanol plant is under construction and scheduled for completion by April 2007. A wastewater treatment plant expansion has also been bid for construction. WWTPs There are two municipal WWTPs in this watershed with design capacities greater than 1 mgd: Windom WWTP and Worthington WWTP. Table 3.9b summarizes the design capacity and historic flows for the plants. These WWTPs, with a design capacity total of 5.8 mgd, discharged over 3 mgd in 2005. WWTPs in this watershed with design capacities less than 1 mgd have a combined design capacity of 3.1 mgd. As with Heron Lake discussed previously and below, smaller WWTPs in proximity to an industry may be a potential supplier of reclaimed water. With over 30% of the watershed’s wastewater treatment system capacity in facilities less than 1 mgd, and the agricultural industry potential in this area, smaller WWTPs should be evaluated more closely in Task 2.
