To support Loveland’s rapidly growing east side—where new neighborhoods, schools, and businesses are emerging—a major wastewater infrastructure project will begin in late December 2025. This project is part of the City’s broader effort to expand the wastewater system, ensuring it can meet the community’s long-term needs with increased capacity and improved reliability.

Scope of Work

Wastewater System Improvements

Garney Construction will install a new 36-inch wastewater interceptor on First Street from Denver Avenue east to Willow Bend Park. The larger line will relieve pressure on the existing 24-inch pipe and enhance the system’s ability to handle future growth. This work marks the second phase of a planned collection system upgrade that runs from the East Side Lift Station downstream to the Wastewater Reclamation Facility.

A wastewater interceptor is a large underground pipe that carries wastewater to a treatment plant. Acting like a main highway for the sewer system, it collects flow from smaller neighborhood pipes and moves it efficiently down the line. The new line will span about 1,500 feet.

Construction will move from downstream to upstream along First Street, with excavation reaching depths of up to 19 feet. The new line will run parallel to the existing line, boosting both capacity and stability.

Work at the Farmer’s Ditch crossing will begin in early January and continue into February, weather permitting, when the ditch is inactive. At the intersection of First Street and Denver Avenue, deep excavation will require a full closure of First Street from Denver Avenue to Sculptor Drive for about four weeks. Eastbound First Street is scheduled to open in February, while westbound First Street is scheduled to remain closed through May 2026. Detours will be available via U.S. Highway 34 or Mountain Lion Avenue.

Construction Impacts

Traffic & Access

During construction, traffic control measures will be in place to maintain safe travel through the area. Temporary traffic pattern changes should be expected on East 1st Street and, to a lesser degree, North Denver Avenue, but local access to residences and for business deliveries and customers will be maintained.

Schedule

Work will occur along East 1st Street, starting at North Denver Avenue and progressing east. For the most part, work will take place between 7 a.m. and 5 p.m. Monday through Friday. There may be occasional Saturday work.

Pedestrian Safety

For everyone’s safety, temporary construction fencing will be installed around open trenches. Pedestrians are encouraged to use caution and maintain a safe distance from construction activities at all times, both during and after working hours.

Planning and Funding

The City’s 2021 Wastewater Collections System Master Plan identified a capacity limitation in existing infrastructure in the Eastside and New Boyd Basins. This is a high priority improvement project due to anticipated growth in east Loveland.

The Project is funded with 2025 Wastewater Utility budget funds. Garney Construction, a water utilities contractor, has been awarded a construction contract for completion of this work. The total contract amount for this work is $3,166,866.00. The project is anticipated to begin construction in January of 2026 and is expected to be complete by May of 2026.

The planning and launch of this project remain on schedule and under budget.

    East First Street Closure Extended Due to Ground Conditions

    Construction for the First Street Wastewater Improvements project is ongoing. Due to unexpected ground conditions, the full closure of East First Street, just east of North Denver Avenue, will be extended. Local residents, businesses and emergency vehicles will still have access.

    Groundwater and wet soil are making it hard to build a solid base for new pavement. The soil conditions are not ideal, so crews need more time to refill the trench, dry and stabilize the ground, and add structural materials (rock). This makes the work take longer than usual. In the coming weeks, lanes are expected to reopen in phases as work progresses.

    Detour Information:

    During the closure, traffic will follow these detours:

    • Eastbound detour: Eastbound traffic on First Street will be detoured north on Denver Avenue, east on US 34/Eisenhower Boulevard, and south on North Boyd Lake Avenue.
    • Westbound detour: Westbound traffic traveling to First Street will be routed east on First Street (which becomes Corvus Drive and then Fifth Street) to North Boyd Lake Avenue, then north to US 34/ Eisenhower Boulevard, west to Denver Avenue, and south back to First Street.

    The schedule is subject to change due to weather or other unexpected conditions. For questions about the project, please call 970-783-7225 or email firststreetimprovementsproject@getinfonow.us.

    East First Street Full Closure Extended Through Mid-April

    Loveland, Colo. – March 25, 2026 – The City of Loveland will extend the full closure of East First Street, just east of the North Denver Avenue intersection, through mid-April because current conditions do not allow the eastbound lane to safely reopen during wastewater pipeline installation. Access will be maintained for local residents, businesses and emergency vehicles.

    Before construction began, the City took steps to identify underground conditions to plan safe travel through the work zone. Despite these efforts, crews have encountered unexpected utility conflicts and varying soil conditions during construction.

    Keeping the full closure in place is expected to speed up construction and could allow the road to reopen two to three weeks early, in early May. After the full closure, the eastbound lane will reopen to through traffic, while the westbound lane will remain closed into early May. The project is expected to be completed by June 2026.

    Detour information

    During the full closure, eastbound traffic on First Street will be detoured north on Denver Avenue, east on U.S. 34/Eisenhower Boulevard and south on Boyd Lake Avenue. As crews move east, they will work to reopen sections of the road for additional local access as soon as it is safe.

    Westbound traffic will detour east on First Street, which becomes Corvus Drive and East Fifth Street, to connect with Boyd Lake Avenue. Traffic will then travel north to U.S. 34/Eisenhower Boulevard, west to Denver Avenue and south back to First Street.

    The project schedule is subject to change due to weather or other unforeseen conditions.

    First Street Wastewater Interceptor Project Begins

    LOVELAND, Colo - December 9, 2025 - A major wastewater project is set to begin in later this month to support Loveland’s rapidly growing east side, where new neighborhoods, schools and businesses are continuing to take shape. Early work will focus on preparing the site, including establishing staging areas, installing erosion controls, removing select trees and conducting utility potholing and drilling. Equipment staging will take place outside the right-of-way south of the E. First Street and North Denver Avenue intersection, as well as at the northeast corner of Willow Bend Park. No lane closures will impact traffic during this stage of work.

    To meet the community’s long-term needs, the city is expanding its wastewater system to increase capacity and improve reliability. Garney Construction will install a new 36-inch wastewater interceptor from Denver Avenue east to Willow Bend Park. The larger line will provide additional capacity within the basin and enhance the system’s ability to handle future growth. This work marks the second phase of a planned collection system upgrade that runs from the East Side Lift Station downstream to the Wastewater Reclamation Facility.

    A wastewater interceptor is a large underground pipe that carries wastewater to a treatment plant. Acting like a main highway for the sewer system, it collects flow from smaller neighborhood pipes and moves it efficiently down the line. The new line will span about 1,500 feet.

    Construction will move from downstream to upstream, with excavation reaching depths of up to 19 feet. The new line will run parallel to the existing line, boosting both capacity and stability.

    Work at the Farmer’s Ditch crossing will begin in mid-January and will continue into February, when the ditch is inactive. At the intersection of First Street and Denver Avenue, deep excavation will require a full closure of First Street from Denver Avenue to Sculptor Drive for about four weeks. Eastbound First Street is scheduled to open in February, while westbound First Street is scheduled to remain closed through May 2026. Detours will be available via U.S. Highway 34 or Mountain Lion Avenue.

    The project remains on schedule and under budget.
