Alpine Aqueduct Reach 1
Replacement and Resiliency Project
Alpine Aqueduct Reach 1 Construction Project Overview
The Alpine Aqueduct Reach 1 (AA-1) is a critical water supply facility that services over 1.6 million Utahns. The current alignment of AA-1 is approximately 1.4 miles in length and runs from the Olmsted Reservoir (near the mouth of Provo Canyon) to the Don A. Christiansen Regional Water Treatment Plant (DACRWTP), north of 800 North in Orem.
In March, the Central Utah Water Conservancy District (CUWCD), in partnership with the U.S. Department of the Interior, began construction on the Alpine Aqueduct Reach 1 project. This essential project will realign the existing aqueduct to better protect residents and maintain reliable water service. This project includes installing a new 108-inch diameter aqueduct along 1060 North, and sections of Somerset Drive (1360 East) and 1560 East in Orem. The project is expected to be complete in early 2027.

Why Was This Alignment Selected?
CUWCD completed a comprehensive resiliency study of the Alpine Aqueduct Reach 1 to understand the risks associated with the existing alignment. The major risks to the aqueduct are seismic events and landslide movement. The study developed several aqueduct realignment alternatives and evaluated each according to the project resiliency and operation criteria. Using the resiliency study recommendations, CUWCD and the Department of the Interior, as Joint Lead Agencies, completed a National Environmental Policy Act (NEPA) study, along with additional studies to determine the best alignment.
Following a public meeting, the agencies selected a Preferred Alternative with the alignment that included 1060 North because it avoids the landslide complex, improves the physical integrity, functionality, and long-term viability of the aqueduct.

What to Expect During Construction
In 2025, the AA-1 project team will relocate utilities throughout the neighborhood to prepare the area for the new aqueduct which will be installed in 2026. Here are some things you can expect during construction this year:
-
Daytime work, Monday - Saturday
-
Between 7 a.m. - 7 p.m.
-
-
Increased dust, noise, and vibration
-
Daytime driveway closures (up to two days)
-
Park strip tree removal and landscaping impacts
-
Minor utility service interruptions
-
Major utility relocations
-
Parking restrictions
-
Traffic detours
-
Regular notices from the project team regarding impacts
