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 2025, the Central Utah Water Conservancy District (CUWCD), in partnership with the U.S. Department of the Interior (DOI), 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 completed in early 2027.

Why Was This Alignment Selected?
CUWCD completed a comprehensive resiliency study of the AA-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 DOI, 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 for the alignment that included 1060 North because it avoids the landslide complex and improves the physical integrity, functionality, and long-term viability of the aqueduct.

What to Expect During Construction
This year the AA-1 project team is installing the 9-foot-diameter pipe along the new aqueduct alignment throughout the Orchard North neighborhood. Here are some things you can expect during construction this year:
-
Active construction work, Monday–Saturday
-
Between 7 a.m. and 7 p.m.
-
-
Increased dust, noise, and vibration
-
Major excavation, driveway, and road closures (up to three weeks) along portions of Somerset Drive, 1060 North and 1560 East
-
Temporary parking lot on the east side of 1560 East at 1060 North, with 24/7 security and shuttle service
-
-
Restricted street parking
-
Heavy equipment entering and exiting the work zone
-
Regular notices from the project team regarding impacts
