Industries and Proximity to WWTPs
While both sand and gravel washing operations are within 5 miles of the Luverne
WWTP, as shown on Figure 3.13b and in Table 3.13a, their limited water use and use
of a surface water supply do not make them a good candidate for reclaimed water.
Given this is a limited water supply area, Task 2 work may be directed at looking at
the industries using a municipal water supply.

Factors Influencing Potential for Industrial Reuse
Like the Des Moines River watershed, the water supply in the Missouri River
watershed is lacking in quality and quantity. This part of the state is in Ground Water
Area 5 known for a limited supply in the bedrock and buried sand aquifers and only a
moderate supply in the surficial aquifer. Some areas of this watershed are in Area 6
which has limited supplies in all the aquifer levels. The surficial aquifers in this area
have been classified as medium to high for susceptibility to contamination, with some
pockets of less concern. Similar issues exist here as described for the Des Moines River
watershed.
Rainy River Watershed
Industrial Water Use
The least populated watershed of the state, the Rainy River, has few industries with a
water appropriations permit. As shown in Table 3.14a and Figure 3.14a, the pulp and
paper industry is the largest water user, dominated by Boise White Paper near the
NKASD plant. Of the 47 mgd used in 2004, less than 0.2 mgd was used for the other
two types of industry, mine processing and sand and gravel washing. Boise White
Paper uses only a surface water supply for its industrial uses. Potlach Corporation
uses ground water supplies totaling less than 0.07 mgd.
