Construction Projects

Improving our infrastructure to ensure access to high-quality, reliable water for generations

The Fort Collins-Loveland Water District serves over 67,000 customers spanning approximately 60 square miles across parts of Fort Collins, Loveland, Timnath, Windsor and Larimer County. For over 60 years, we have been dedicated to our mission of providing high-quality, secure, reliable, and affordable water. To ensure that we are well-positioned to meet the water needs of current and future customers for generations to come, the District has developed a Capital Improvement Plan (CIP) as part of our long-range master planning strategy.

The CIP includes a variety of construction projects such as the installation of new pipelines, maintenance and repair of water infrastructure such as pipelines and pump stations, and the construction of new storage facilities. These projects are crucial for ensuring access to clean and safe water, improving water infrastructure and meeting growing demands.

We understand these projects can be an inconvenience. Please know our team is working diligently to complete projects quickly and efficiently to minimize the impact. This page is designed to provide customers and our community with information on current and upcoming projects within the District . If you have any questions or concerns about a project please contact our office at (970) 226-3104  or send us a message through our contact form .

Current Projects and Improvements

Zone 5 Project – Harmony Crossing

March 20-25, 2025

The Zone 5 Project is a multi-phase project stretching approximately 8 miles across the City of Fort Collins. Existing FCLWD infrastructure is undersized for current and future flow needs, resulting in dependence on pump stations and alternative water delivery sources. The Zone 5 project will increase hydraulic capacity and improve overall system performance and reliability. The completion of this project is critical to continue to deliver reliable and affordable water to our customers. During phase 3 of the project, we will be installing a 24″ water line across Harmony Road at Boardwalk Drive. This is in collaboration and ahead of multiple City Projects along the Harmony Corridor.
It is not expected that water services will be interrupted as part of construction. If an interruption is necessary, residents will be notified via a door hanger 24 hours in advance.
During the project, the following areas will be impacted with roadway restrictions, detours and closures. Please follow all crew instructions and signage and be prepared to use detour routes, park on adjacent streets and allow additional time for commuting. 

  • March 20-21 | Northbound Boardwalk Dr. closed south of Harmony Rd.
  • March 22-23 | Full closure of Harmony Rd. crossing Boardwalk Dr.
  • March 24-25 | Northbound Boardwalk Dr. closed North of Harmony Rd.

Please Note: dates are estimates based on favorable weather conditions and are subject to change.

Trilby Tank Expansion

March 2025 – December 2026

The Fort Collins Loveland Water District has identified the need for an additional finished water storage. Previous studies identified an opportunity to expand storage near the existing Trilby Tank site on the north side of Trilby Road near the Larimer County landfill. The increased water storage in this location will aid with buffering the current and future water demand and provide additional water to fight fires. The project will result in a new six-million-gallon water storage tank to be constructed on a new parcel of land north of the existing four-million-gallon storage tank.

Construction is scheduled to start in March 2025 and is expected to continue for approximately 20 months, anticipated to be completed in December 2026.

It is not expected that water services will be interrupted as part of construction. If an interruption is necessary, residents will be notified via a door hanger 24 hours in advance.

During the project, commuters may encounter minor roadway restrictions. Please follow all crew instructions and signage and allow additional time for commuting.

Longview Pump Station

April 2025 – April 2026

The Fort Collins - Loveland Water District has identified the need to upgrade the pump station serving the Longview subdivision, as the current facility has exceeded its design life and requires modernization. The existing station, which is below grade, has aging pumps that need replacement. The new pump station will be constructed at grade with an improved above-grade design, upgraded pump suction systems, increased fire pump capacity and backup power to enhance reliability and efficiency.

Construction is scheduled to start in April 2025 and is expected to continue for approximately 12 months, anticipated to be completed in April 2026.

The new pump station will be built on the current site, and once it becomes operational, the old station will be demolished.

To facilitate construction access and deliveries, a portion of one eastbound lane will be temporarily closed for the duration of the project. However, 71st Street will remain open at all times.

Planned water outages will be necessary for this project. Major tie-ins will impact water service but will be completed outside of normal business hours to minimize disruption. The District will notify all affected businesses in advance of any scheduled outages.

Western Backbone – Phase 3

February – October 2025

The Western Backbone Transmission Pipeline Project is part of the District’s ongoing system improvements. This project will replace four miles of undersized transmission mains along the western edge of the district’s service area. It also will increase hydraulic capacity and improve overall system performance. The first phase was completed in 2023  and the second phase was completed in 2024 .The remaining phases will be constructed in subsequent years.

Phase 3 of the Western Backbone project is anticipated to begin in the first part of 2025. This phase will take place between Overland Trail and Prospect Road along Pleasant Valley Road, Virginia Dale Drive. Wildwood Road, Lake Street and Cedarwood Drive. See the map for specific timeframes. The construction schedule is an estimate based on ideal weather conditions. Weather and other delays to this schedule may occur.

Western Backbone – Phase 3

What to Expect

Driveway Access
  • Work will be completed under a rolling closure, meaning the road will only be fully closed at the current excavation site.
  • There will be soft closures for local traffic only as you enter your neighborhood, but residents should have access to your driveways for most of the construction.
  • There will likely be a two-day period during pipe installation where those along the construction route will not be able to access driveways.
  • There will also likely be a two-day period during paving operations where residents will not be able to access driveways. If concrete repairs are necessary in front of your driveway, an additional 2-3 days may be needed.
  • Residents will be notified by door hanger 24 hours before changes to driveway accessibility.
  • Residents can park in the Overland Park parking lot when access to driveways is impacted.
Construction Hours
  • Construction may take place 7 a.m. – 6:30 p.m., Monday thru Friday. Work will only occur on Saturdays if there are delays due to weather or other unforeseen circumstances. Residents will be notified if work will be performed on Sundays. No work will be done on major holidays.
Deliveries, Trash and Service Providers
  • Crews will assist with trash pickup.
  • Crews will also allow access to mail carriers and delivery drivers.
  • The project contractor will make reasonable concessions to allow personal service providers access to impacted properties.

Why is Fort Collins-Loveland Water District doing work in my neighborhood when I get my water from Fort Collins Utilities?

Fort Collins has several different water providers, including Fort Collins Utilities and Fort Collins-Loveland Water District. Water treatment facilities for both utilities are in northwest Fort Collins due to the access to water supplies in Horsetooth Reservoir and the Poudre River. While Fort Collins Utilities serves most of the main part of Fort Collins, water still needs to be distributed to other neighborhoods in southern Fort Collins and northern Loveland, which is where these projects come in. It allows the district to better provide water to its customers.
