Industrial Processing Water Use in the Rainy River Watershed, 2004 Source: MDNR, 2004 WWTPs There are two municipal WWTPs in this watershed with design capacities greater than 1 mgd: NKASD in International Falls and the Ely WWTP. Table 3.14b summarizes the design capacity and historic flows for the plants. These WWTPs discharged nearly 2 mgd in 2005. There are also several smaller WWTPs that discharge to surface waters with a combined design capacity of 3.3 mgd. This compares to a total WWTP capacity of 7.1 mgd for the watershed. Depending on the location of the industry it is possible that a smaller WWTP could provide an adequate reclaimed water supply.

There are no industries in Ely that have their own water permits. Table 3.14c.

This area is Ground Water Area 3 and is dominated by glacial aquifers that are commonly thin and limited in their extent and yield. The bedrock aquifers also have limited yield; there are no large-scale regional aquifers. Ground water movement in much of the area is difficult to define because of the fractured nature of the bedrock. In the west (Area 4) and north (Area 5) portions of the watershed, the ground water supply in the surficial aquifers are less shallow and have moderate to good yields. This area can be dominated by connections to wetlands and contamination of surface aquifers has occurred. However, overall this watershed has a lowest to low susceptibility to contamination index, except along the southern border and interspersed areas in the watershed. 3-30 Craddock Consulting Engineers In Association with CDM & James Crook WWReuseTM1_Sec 3_final.doc
