Whether your lawn drinks treated city water or a second, untreated pipe depends on your city, and sometimes on your street. This page lays out, city by city, who runs pressurized irrigation (PI) in Utah County, how big each system is, when it runs, and what the rules and meters look like. We read each city's PI page and the water plans that Utah cities filed with the state Division of Water Resources on October 20, 2026.

For what secondary water is, how water shares work when you buy a house, and the vocabulary, read our secondary water guide. This page is the city-by-city reference.

Provo's water plan, filed in 2026, does not describe a city-run pressurized irrigation system; its outdoor conservation steps focus on landscaping, smart controllers and rain barrels. If you are buying in Provo, ask the seller whether the property has an irrigation company share or a secondary hookup, and check the title report.

City notes

Lehi runs two systems, drinking water and PI, and its PI is fed by wells, canal diversions and the Central Utah Water Conservancy District, with 229 acre-feet of storage in 13 facilities. Lehi is in Phase 2 of its Water Shortage Management Plan (revised April 9, 2026): no sprinkling on consecutive days, two days a week, at least 48 hours apart. Its plan says tiered PI rates will start once every service is metered. Turn your connection off by October 15.

Saratoga Springs draws PI from five wells and surface water and stores it in 11 ponds totaling 113.4 acre-feet. Billing is a flat monthly charge all 12 months, plus a tiered rate in season that rises when use exceeds the property's allotment. Wait two weeks after the spring charge before running, keep systems off from 10 a.m. to 6 p.m., and close your own shut-off valve after November 1. The My Water Use portal shows hourly use for both systems.

Highland fills and charges its system starting at the end of March, which can take two weeks; keep your valve closed during charging, because pressure swings can damage a private system. A filter is required. Meter installation began in summer 2023.

Lindon's system was installed around 1993. The city's metering project called for 2,616 meters, with installation scheduled through summer 2023, funded by $1,963,000 from the state, $400,000 from the Central Utah Water Conservancy District and $841,000 in city money, and the city expects metering to cut use by up to 20%. PI is billed monthly, year-round.

Mapleton's PI serves the north and central parts of the city; the rest irrigate from culinary water, and dry mains could bring PI to about 1,500 more connections. Its plan (amended August 2025) publishes a tiered PI rate for users with access: a $15 base for 3/4-inch and 1-inch meters, then $1.00 per 1,000 gallons up to 8,000 gallons, $1.25 to 100,000, $1.50 to 200,000, and higher tiers above that.

Springville's PI went into service in 2016 and serves more than 1,500 connections on the west side. The city prices PI below culinary water to encourage its use, runs tiered rates on both systems, and asks residents to avoid watering from 10 a.m. to 6 p.m.

Spanish Fork owns the PI line from the main through the meter to the first fitting after it; everything past that is the owner's. The season runs about mid-April to mid-October, with exact dates set each year.

Pleasant Grove's November 2025 draft water plan says secondary metering and a tiered rate structure were near completion, and that current irrigation demand exceeds infrastructure capacity.

Orem has no general secondary system, according to its water plan. Its plan sets a goal of producing Type 1 reuse water at the city's water reclamation facility by 2025 to irrigate The Links at Sleepy Ridge, Lakeside Sports Park and Springwater Park.

Eagle Mountain and Vineyard list secondary water as a planning goal: Eagle Mountain is pursuing wastewater and industrial reuse for a secondary system, with a reuse permit awaiting state approval, and Vineyard's plan calls for a secondary water master plan.

The 2030 meter deadline

Utah Code 73-10-34 requires every pressurized secondary water supplier to meter each user by January 1, 2030, and new service in Utah County has had to be metered since 2020. A supplier may not raise rates more than 10% in a calendar year for metering costs, except after a catastrophic failure, and must explain the basis of an increase. Once meters are in, expect tiered pricing: the more you water, the more each gallon costs.

What to do as an owner

Find out what you have. Look for a second shut-off valve and meter box in the yard, or ask your city's utility billing office.
Respect the season. Keep your valve closed until your city says the system is charged, and winterize after shutoff; our sprinkler winterization guide covers it.
Fit and clean a filter. Untreated canal and river water clogs heads.
Never cross-connect PI to your drinking water. It is prohibited and can contaminate the house supply.
Watch the meter. If your city has a portal, check weekly in July; that is when tiered bills climb. The Utah Division of Water Resources' weekly watering guide tells you how much your lawn needs.

Frequently Asked Questions

Which Utah County cities have pressurized irrigation?

Among the cities whose plans and pages we read, Lehi, Saratoga Springs, Highland, Lindon, Springville, Spanish Fork, Mapleton and Pleasant Grove run pressurized irrigation (PI) systems. Orem's water plan says the city lacks a secondary water system. Coverage inside a city can be partial: Springville's serves the west side, and Mapleton's serves about half its service area.

When does pressurized irrigation turn on in Utah County?

Mid-April in most systems. Saratoga Springs charges its system the week of April 15, Highland makes water available April 15, and Springville's 2024 notice said charging began April 8 with the system ready April 15. Spanish Fork says around mid-April, and Lindon says approximately the end of April.

When is pressurized irrigation shut off?

Around October 15 in most cities. Saratoga Springs drains the week of October 15, Highland's season ends October 15, Lehi asks residents to turn connections off by October 15, and Spanish Fork and Lindon say mid-October.

Is secondary water metered in Utah County?

It is becoming so. Utah Code 73-10-34 requires every secondary water supplier to meter each user by January 1, 2030. Saratoga Springs reports 10,728 metered PI connections, Lindon's metering project called for 2,616 meters, scheduled through summer 2023, Highland began installing meters in 2023, and Lehi says most connections are metered.

Will my secondary water bill change after metering?

It can. Several cities use or plan tiered rates that charge more per gallon at higher use: Lehi says tiered PI rates will follow full metering, and Saratoga Springs and Springville already use tiers. Utah law limits metering-related rate increases to 10% a year, with exceptions.

Can I drink pressurized irrigation water?

No. Lehi and Highland both warn that it is untreated; Lehi says it can carry bacteria such as E. coli. Never connect it to your drinking water plumbing.

Do I need a filter on pressurized irrigation?

Highland requires one because most of its PI water is unfiltered surface water, and Lindon says its water is screened but not filtered. A filter protects sprinkler heads and drip lines; clean it when pressure drops.

Are there watering-day rules on secondary water?

Some. Lehi, in Phase 2 of its water shortage plan, limits watering to two days a week with at least 48 hours between cycles and no consecutive days. Saratoga Springs asks residents not to run systems between 10 a.m. and 6 p.m. except for new grass or maintenance.
