Mississippi River Watershed WWTPs
The WWTPs that discharge to the Mississippi River-Headwaters watershed from
upstream to downstream include: Rogers, Metropolitan, Rosemount, Eagles Point,
and Hastings. The Empire WWTP currently discharges to the Vermillion River, a part
of the Lower Mississippi River watershed. Upon completion of facility and interceptor
construction, the discharge will move to a new discharge point on the Mississippi
River in the vicinity of the existing Rosemount WWTP discharge.
The 1.6 mgd Rogers WWTP has only two industries within a 5-mile radius (both
located within 1 mile) of the plant with a total demand of 0.05 mgd. Figure 3.22 and
Table 3.20 identify these industries as sand and gravel washing businesses, one of
which does other processing operations.

The largest WWTP in Minnesota, the 250 mgd Metropolitan (Metro) WWTP, has a
diversity of industries within a 5-mile radius of the plant, as shown on Figure 3.23. A
chemical company, Hawkins Chemical, with a demand of 0.1 mgd, is located within
1 mile of the plant. In the 5-mile zone around the plant, the industrial water demand
is 0.96 mgd for nonpotable supply, and 17 mgd for combined municipal and
nonpotable supplies. Table 3.21 lists these facilities and their industry type.
