water restrictions lifted in the vialetto area
Update as of July 9
The Phase 2 outdoor water restrictions for the Vialetto pressure zone have officially been lifted.
We appreciate your patience and cooperation as the Lehi City Water Department and our partner contractors worked to get the new pressurized irrigation reservoir fully operational.
As always, we encourage residents to continue practicing wise watering habits to help conserve our water resources.

PI WATER REMINDER: Unlike culinary water, pressurized irrigation water is not treated, making it vulnerable to contamination and harmful bacteria, such as E. Coli.
Please review the following important reminders from the Utah County Health Department.
Irrigation water is for lawns not for drinking
Drinking or playing in irrigation water can pose a health risk
Irrigation water is untreated and may contain harmful bacterium
Irrigation water should not be used for bounce houses, pools, slip-n-slides, etc.

Reservoir in Testing Phase – Restrictions Extended to July 9
The Lehi City Water Department is pleased to provide an update on the pressurized irrigation (PI) reservoir project serving the Vialetto pressure zone on Traverse Mountain.
The reservoir is currently in the testing phase, and the service date has been extended the second week of July to allow time for necessary testing and inspections to ensure the system is operating safely and efficiently.
We appreciate your continued patience and cooperation. While this process is completed, Phase 2 outdoor water restrictions will remain in place through at least July 9, 2025.
Effective May 31
Residents of the Vialetto area on Traverse Mountain will be under Phase 2 outdoor water restrictions beginning Saturday, May 31. This temporary measure is necessary due to a delay in construction of the new pressurized irrigation (PI) reservoir that will serve your neighborhood.
Originally scheduled for completion in April, the reservoir project encountered unforeseen issues that have delayed progress. Construction, repairs, and system testing are now expected to be completed by July 1.
What Phase 2 Water Restrictions Mean
- No sprinkler irrigation on consecutive days
- Sprinkler irrigation is limited to two days per week, with at least 48 hours between watering cycles
These restrictions are in place to help manage limited resources and ensure adequate water is available throughout the system during this critical construction phase.
Map of the Affected Area
To see if your property is impacted, view the map below outlining the Vialetto pressure zone currently affected by these restrictions:
Why This Matters
For over 30 years, Lehi’s PI system has reliably provided irrigation water for landscaping and has supported essential fire suppression infrastructure.
Currently, the Vialetto area is being supplied by culinary water, which is intended for indoor use and is not a viable long-term solution for outdoor irrigation. Completing the new PI reservoir is a critical step in restoring sustainable water service to your area and strengthening overall water infrastructure.
Planning Landscaping? Please Delay New Sod
We understand that many residents begin landscaping projects in late spring and early summer. However, we strongly recommend postponing the installation of new sod until after July 1. New sod requires frequent, consistent watering to establish, which is not compatible with current Phase 2 watering restrictions.
Water Shortage Management Plan
These temporary restrictions align with Lehi City’s broader Water Shortage Management Plan, which guides how we respond to supply challenges and prioritize system improvements.
