Professional services have included funding/financial studies, rate studies, sanitary sewer collection, wastewater facilities planning, scheduling, flow monitoring, design and construction administration, and advanced tertiary metals removal. RPA recently completed a solid waste operational analysis and rate study for the City to analyze the solid waste rates, existing revenue, existing expenditures, and to discuss potential solid waste rates for two separate alternatives. RPA has just finished the design for installation of new water distribution mains in two separate locations. In addition, RPA designed a new 1.0MG prestressed concrete water storage tank and appurtenances.

Westside Interceptor

Project Description

The City of Kalispell, in partnership with the Montana Department of Environmental Quality – State Revolving Loan Program, developed an 8.25-mile long sewer interceptor along the west side of Kalispell. The design team examined potential alignments and design considerations for the new infrastructure. The new sewer interceptor generally followed existing city streets and rights-of-ways in the southern most segment, and then crossed BNSF railroad and US Highway 93 – Alternate (Bypass) to the west side of US Highway 93 Alternate. From here, the sewer interceptor followed existing rights-of-ways and crossed private properties to the northernmost termination near US Highway 93 North and Reserve Street. The sewer interceptor crossed both Ashley and Spring Creeks (floodplain development permits), US Highway 2 and Three Mile Drive (bore and jack casings) and included several Horizontal Directional Drills (forcemains). RPA provided professional civil engineering and land surveying services to the City of Kalispell and was the Prime Consultant for this important sewer interceptor project. Specific services provided included: Preferred Route Assessment, land and topographic surveying, right-of-way acquisition, design services, funding assistance, and construction administration.
