JR Engineering provided planning, design, and construction documents for the Lutz Reservoir Pump Station, which is a key component of the City of Brighton's non-potable irrigation system. The project leveraged the existing 140-acre-foot lined Lutz Reservoir storage facility to deliver non-potable irrigation water to existing and future development throughout a 3.2-square-mile service area. By utilizing reclaimed irrigation storage rather than the City’s potable water system, the Lutz Pump Station project significantly reduced demand on the City's drinking water supply while supporting long-term community growth.

System Planning & Demand Analysis

The project began with a comprehensive irrigation demand analysis. JR Engineering evaluated metered potable irrigation usage from existing commercial developments and public streetscapes and combined that measured demand with City-provided planning information for future subdivisions and projected land uses, in order to develop projected average and peak irrigation demands. Working closely with the City, the team established a phased development strategy that aligned anticipated growth with four incremental pump station expansion phases, ensuring the facility could efficiently meet system demands through ultimate build-out.

Hydraulic Modeling & Pump Station Design

JR Engineering developed a hydraulic model of the ultimate non-potable distribution network to evaluate non-potable system pressures, flow demands, pump sizing, total dynamic head, system phasing, and system curves by phase. With approximately 160 feet of elevation difference across the service area, maintaining acceptable operating pressures presented a significant design challenge. The analysis led to the incorporation of strategically located pressure-reducing valves within the future distribution system, providing reliable service during peak irrigation demands while preventing excessive pressures in lower-elevation areas during periods of reduced demand.​ The pump station was designed with an ultimate pumping capacity of 6,000 gallons per minute. The ultimate facility will feature seven pumps of varying capacities, with just three vertical turbine pumps and a low-flow pump installed as part of the initial construction.  Provisions for future pump installations were included using roof access hatches.  The pumps draw water from a 27-foot-deep reinforced concrete wet well supplied by intake lines from the existing reservoir. Instrumentation and control systems were housed in a dedicated control room, separated from the pump and piping area to enhance operational reliability and maintenance access.

​

The pump station was designed in accordance with City of Brighton standards and coordinated with the City's Planning Department to ensure the CMU and metal-roof architectural design complemented its open space location and the surrounding development. The completed facility provides the City with a reliable, expandable non-potable irrigation system that conserves potable water resources while supporting continued growth throughout the service area.

Transmission Main & Construction

JR Engineering also designed approximately 6,500 linear feet of 16-inch non -potable transmission main along S 27th Avenue, connecting the new pump station to the City's existing non-potable distribution system that had previously relied on a potable water interconnect at Prairie Center.  The transmission line was placed outside the future S 27th Avenue widening within new utility easements, but crossed multiple existing utilities in the corridor. JR Engineering managed construction of the project (2024-2026). JR Engineering’s surveyors prepared parcel and easement legal descriptions for land acquisition associated with the project.
