West Post Subdivision Water Infrastructure

Situated in Belgrade, Montana, West Post Subdivision is a 236-acre mixed-use project set to provide commercial, retail, multifamily, and single-family properties.

Apart from designing roadway infrastructure, Sanderson Stewart’s Municipal Group and Water Studio tackled three significant water-related obstacles on a tight schedule.

DITCH RECONFIGURATION

An existing irrigation ditch was reconfigured and routed through two in-line infiltration ponds to limit discharge to the property to the north.

WATER BOOSTER STATION

The southern section of the subdivision had inadequate water pressure and did not meet the requirements for the intended residential and commercial structures. The solution; a four-pump booster station was designed, modeled, and installed, along with strategically placed pressure-reducing valves to isolate the area and prevent it from affecting the rest of the City. This improvement made it possible for the project to move forward.

STORM DRAIN CHAMBERS

Multiple underground storm-tech chambers were designed to collect and release stormwater runoff that historically infiltrated the undeveloped property through overland flow. This system will help recharge the City of Belgrade’s aquifer.
