Buried Pipeline in Field

The Northern Integrated Supply Project (NISP) includes approximately 36 miles of buried raw water pipelines in Larimer County to move water from the proposed Glade Reservoir to the NISP participants. The new pipelines will provide a safe, high-quality, year-round water supply to local communities in Northern Colorado.

Many pipeline routes were developed and analyzed through multiple pipeline routing studies. An Impacts Minimization Plan was used to decrease impacts on public, private and environmental resources with the pipeline route. Alignment options were developed to minimize the following: street crossings and traffic disturbances; construction impact on trees, wetlands and other natural resources; proximity to occupied homes and dwellings; and existing and future development. The pipeline construction will not require any occupied homes or residences to be removed.

The NISP Pipeline will begin at the proposed Glade Reservoir and will generally head east and south to deliver water to the NISP participants. An additional Poudre Delivery Pipeline will bring water from Glade Reservoir directly to the Poudre River. NISP participants have committed to a “refined conveyance” concept with the goal of keeping more flows in the Poudre River year-round. This is accomplished by putting some of the water to be delivered from Glade Reservoir to the NISP participants directly into the river to be picked up east of Fort Collins. This will provide positive benefits to the river corridor and enhance the aquatic and riparian environment.

A typical width of 100 feet is anticipated to construct the pipeline. This area facilitates quicker and more efficient construction; however, a smaller work area is used where existing constraints and utilities may limit space. Approximately 60 feet of this width would be utilized as a permanent easement to access the pipeline in the future, while 40 feet would be acquired temporarily and used only for the initial construction. This 100-foot-wide corridor will be modified as needed in tight construction areas and where existing constraints limit the construction space.

Additional information on the NISP Pipelines can be found in the document library to the right.

A preliminary pipeline route is shown in the Pipeline Map tool below. As more information is gathered and the design progresses, the pipeline route may change slightly from the presented route.
