North Area Tanks Water and Reuse

Background Information

Broomfield needs the ability to store additional water, specifically in the areas north of W. 144th Avenue, and a tract of land in Anthem Filing 24 was dedicated to Broomfield for future water tanks by the Anthem developer. If development continues without the necessary water infrastructure, there will be inadequate storage and supply for fire flows. Regular, peak-hour usage will result in inadequate water supply and pressures to the higher elevation properties. 

Broomfield’s water system model identified capital improvements that will be needed as Broomfield develops. The model specifically focuses on the phased development of the areas north of W. 144th Avenue that are quickly developing.  In anticipation of the future water tanks, a tract of land was dedicated to Broomfield with the platting of Anthem Filing 24 in 2016, and was included in the approved site development plan.  Due to the necessary hydraulic grade elevation, a booster pump system is required.

The project initially included a third storage tank for storage of reuse water.  At this time, the reuse tank will not be constructed.  By modifying the time of use within the reuse system, Broomfield anticipates demands will remain within the capacity of the existing reuse system.

Preliminary Design Report

News and Updates

City Council approved the Site Development Plan Amendment for partially buried tanks at the July 23, 2024 meeting.  At the October 28, 2025 meeting, Council approved a construction agreement with Garney Construction for the Broomfield Tanks Project. 

Construction is expected to begin in January 2026 and last 24 to 33 months, depending on weather conditions and material availability.  For the safety of residents and trail users, the soft trail and open space area will be closed between Lowell Boulevard and the trail at Irving Court.  The sidewalk along the east side of Lowell will be closed as well as the trailhead parking lot at Lowell Boulevard (King Court).

The Burns & McDonnell agreement for a preliminary design and feasibility report was approved by Council in July 2021.  The report included the size and number of both potable and reuse tanks needed, confirmed the need and size of the booster pump stations, layout of the site for the tanks, booster pump stations, utility lines, and access, a probable cost estimate and schedule, reviewed the water and reuse modeling for the service areas and developed a comprehensive scope to complete the design of the Tank Project.  Council approved a consulting agreement for the design and development of construction documents at the April 26, 2022 meeting.  A design kickoff meeting was held on May 9, 2022 and the 100%  construction documents were completed in late September 2023.

Staff issued a Request for Qualifications/Proposals for a Construction Manager/General Contractor (CM/GC) for the project and a CM/GC was selected and a contract was authorized for preconstruction services with Garney Services.  Garney has been assisting the design team with constructability reviews and cost estimates.

A neighborhood meeting was held on June 29, 2022.  A study session on the project was held on January 17, 2023 for staff to receive direction from Council. The project was presented to the Land Use Review Commission on July 24, 2023.  The Site Development Plan Modification was presented to Council at the September 26, 2023 meeting.  At that meeting, Council did not approve the Site Development Plan Modification and directed staff to redesign the project with fully buried tanks.  

Staff presented a new design agreement and preconstruction agreement to Council at the November 14, 2023 meeting.  Redesign efforts restarted in December 2023 and the design team completed a Site Development Plan (SDP) Modification and a redesign of the project.  In early February 2024, the geotechnical sub-consultant completed additional boring on the site to the required deeper depths.  Staff requested additional testing to determine the extent of hard rock excavation that may be necessary.  The first resubmission of the SDP was submitted to the Planning Division in late January 2024, the second submission was in March 2024.  No further comments were received for the third submittal.  The project was presented to Council at the July 23, 2024 meeting and Council approved the original 2023 Site Development Plan with partially buried tanks.
