Construction of the WSI will accomplish the following objectives: 1. Two existing deviations with the Montana Department of Environmental Quality which limit growth in certain areas of the city will be satisfied with the completion of the WSI; 2. Flows north of Reserve Drive will be diverted to the interceptor, decreasing downstream impacts in the collection system; 3. Flows in portions of Line A will be reduced, providing additional capacity necessary to serve existing infill areas and provide opportunity for needed maintenance repairs; 4. Three existing lift stations will be removed, saving associated manpower, and O&M costs; and 5.
