From surface and ground water supply development, to storage and distribution, our Water Services Group provides system designs for both conventional physical/chemical water treatment, as well as alternative systems.
RPA specializes in water treatment facilities for communities of all sizes. We pride ourselves on the attention to detail that we give all of our projects, keeping in mind the aesthetics, construction costs, and ultimate operation and maintenance of the facility.
Because many of our water clients are small, rural communities with limited resources, our designs must be cost effective, easy to operate and maintain, environmentally friendly, and energy efficient while meeting stringent state and federal regulations.
We have been successful in assisting our clients with project funding, depending upon the client's preference. To fund projects, our clients typically rely on outside sources such as the Montana Department of Commerce (TSEP and CDBG Grants), Rural Development (Loans and Grants), the Montana Department of Natural Resources (Loans and Grants) and the Montana Department of Environmental Quality (SRF Loan Program).
SERVICES WE PROVIDE
Water Supply, Treatment, Storage
Butte-Silver Bow Water System Master Plan
Client: Butte-Silver Bow
The Butte-Silver Bow Water System consists of three sources: the Big Hole River Supply, the Moulton Reservoir Supply and the Basin Creek Reservoir Supply which are all surface water sources. The existing water system was evaluated and recommendations were made for a significant improvements program. A computer model was completed for the water system and was used to evaluate the efficiency of the distribution and storage system.
Recommended improvements included replacement of the 20-mile long Big Hole Transmission Pipeline, replacement of the Big Hole Diversion Dam, installation of an ultraviolet disinfection system on the Basin Creek Supply in order to maintain an existing filtration waiver and various distribution system improvements. A new membrane water filtration plant was recommended in the future for the Basin Creek source in anticipation of the loss of the current filter waiver.
Martinsdale Water and Sewer District Water System Improvements
Client: Town of Martinsdale, Montana
The community of Martinsdale’s existing water supply consisted of a single spring source. The water system improvements project was undertaken to expand the water system’s capacity and improve fire protection. System components included the construction of a new 200,000-gallon steel storage tank, the development of an additional spring source, approximately 12,000 feet of new transmission piping, and the construction of a new disinfection system building at the tank site. Total project costs were $1.5 million dollars.
Key Project Elements:
Kalispell 2.0 MG Tank and West View Well
Client: City of Kalispell, Montana
Improvements to Kalispell's upper pressure zone were necessary to ensure adequate water production and storage capacity to areas of town experiencing extremely high growth rates. The existing upper pressure zone facilities were not adequate to meet MDEQ requirements for source capacity and storage. Recognizing the system shortfalls, the city authorized Robert Peccia & Associates to design a new water storage tank and production well.
The initial phase of the project involved an extensive site selection study to determine the optimum locations for the new reservoir and well. Selection criteria included costs, aesthetics, system hydraulics and tank style. The study's final recommendations included locating a buried tank on Sheepherder Hill and constructing a new municipal well in a city park located in the West View Subdivision.
The new tank is a 2.0-MG prestressed buried concrete reservoir, which will supplement the existing 100,000 gallon elevated steel tank in the upper pressure zone. The new tank is connected to the city's existing distribution system by 8,000 feet of 18” PVC piping. The West View Well utilizes a submersible pump and has a capacity of 1,200 gpm. The well is 397 feet deep and has a 12” diameter casing. A new well building is located approximately 120 feet from the well and houses the electrical controls, pump control valve, disinfection system, diesel-powered emergency generator and a radio telemetry unit.
