pipeline
Construction of the North Core Pipeline project consisted of approximately 70 miles of pipeline from near Ft. Pierre to Philip, four ground storage reservoirs, and four pump stations. The project included 12-inch through 16-inch diameter pipe, valves, stream crossings, and miscellaneous appurtenant work. The pipeline route followed the route of Highways 14/34 with some cross-country segments. Stream crossings were installed using a directional boring method as to avoid disturbance to fish and wildlife. The pipeline system was designed for over 1,700 gpm and brought water service to rural customers and small communities in western South Dakota.
Osceola County Rural Water is a regional water provider whose service territory footprint covers an extensive four county area and over 1,200 square miles in Northwest Iowa. The water system’s continual growth eventually led to water use demands that could not be met by the existing distribution system. Using a calibrated hydraulic model, DGR identified numerous areas of the system needing pipeline improvements to maintain pressure. Additionally, the capacity of originally constructed transmission main had been depleted over the years.
The resulting 56-mile pipeline project was designed, permitted, bid, installed, and started up in less than two years from the project’s inception. The pipeline improvements will serve to accommodate Osceola County Rural Water’s ever growing water demands well into the future.
The City of Marshall Minnesota (population 13,664) is a thriving community in Southwest Minnesota, who relies on ground water to supply safe drinking water. Their growing water demands were exceeding the long-term capacity of their aquifers, which had the MN Department of Natural Resources placing further restrictions on their limited capacity. They had already gone 8 miles outside of town to find water years before… this time they would have to expand their search.
Marshall Municipal Utilities found a new water source which was 27 miles away from their water treatment plant. DGR Engineering designed a combination of 20” & 24” pipeline to deliver this water to the City. We used our knowledge of cost effective rural construction to save Marshall Municipal Utilities millions of dollars in construction costs. In the end, Marshall Municipal Utilities added over 4 million gallons per day of water to fuel their growth for years to come. And with the economical design and bid prices, they had money left in their project budget to tackle other much needed improvements.
