What Homeowners Need to Know About Irrigation Systems in Provo

• Local Soil and Water Conditions

  Many areas near the Provo River and foothills have gravelly alluvial soils (e.g. the “Provo series” soil) that contain a high percentage of rock fragments (50–80% gravel). These gravelly loams have rapid permeability, but because they sit on flat valley floors with a high water table, they can actually be poorly drained (water can linger near the surface). Closer to Utah Lake (e.g. around Provo Bay), the soils tend to be fine-textured silty clay loams. Using a “cycle and soak” watering method is recommended in clay soil – i.e. watering in shorter increments with breaks in between, to let water infiltrate before more is applied. Water in Provo irrigation systems is mostly culinary (potable) water.

• Irrigation Water Information

  Provo City delivers treated drinking water (“culinary water”) to all residents and businesses through its Water Resources Division. This is the primary source used for indoor needs and outdoor irrigation in most of Provo. The city uses a metered, tiered rate structure to bill for culinary water usage, encouraging conservation. As of the latest fee schedule, the base monthly fee for a standard residential 3/4″ meter is about $21.43. Larger connections (often commercial) pay higher base fees. On top of the base fee, water is charged per volume in tiers. For all users, Tier 1 usage is billed at roughly $1.37 per thousand gallons, Tier 2 at about $2.09 per thousand gallons, and Tier 3 at around $2.81 per thousand gallons. The average residential system will be in the tier 1 range, so expect to pay about $100-150 per month in landscape-related water during summer months.

• When to Turn Sprinklers On and Off

  Since Provo City’s water is a year-round culinary supply, there isn’t a hard shut-off of the water system in winter – your household taps and sprinklers are fed from the same source year-round. However, practical winterization is still crucial because of freezing temperatures. Provo’s climate has a definite freezing season: on average the first autumn night at or below 32°F hits around early to mid-October. (In many years, somewhere around October 13–15 is the first freeze in the city’s lower elevations.) By mid-fall, lawn irrigation should be shut down and sprinkler systems blown out to prevent ice damage. Provo’s average last spring freeze (return of nights above 32°F consistently) is in late April – roughly around April 27–30 on average, though it can vary. In fact, it’s wise to wait until about early May before turning sprinklers back on, since late cold snaps have occurred even in May in some years.

• Watering Schedule Regulations

  Provo City emphasizes wise water use and has enacted water conservation measures to reduce waste. A key regulation to be aware of is the guideline on watering times of day. It is strongly encouraged (and effectively required during drought conditions) that outdoor watering NOT be done during the hottest part of the day. Watering lawns only in the early morning or late evening hours is recommended to minimize evaporation loss. In practice, residents are asked not to run sprinklers between about 10:00 AM and 6:00 PM on any day, since mid-day sun and heat can cause 20–30% of the water to evaporate before it ever soaks into your grass. By watering in the cool of morning or night, you ensure more water goes to the plants and less is wasted.

• Rebates & Incentives for Conservation

  Provo City actively supports residents in upgrading to more water-efficient landscape equipment and designs. In addition to statewide programs like Utah Water Savers (Slow The Flow) rebates, Provo offers its own local incentives and rebates for water conservation. These programs (which are up-to-date as of the mid-2020s) can help homeowners and sometimes businesses save water and money. High-Efficiency Sprinkler Nozzle Rebate: Provo provides a $3 rebate per sprinkler nozzle when you replace old spray heads with qualifying high-efficiency rotary nozzles. This can greatly improve irrigation uniformity by delivering water more slowly and evenly. The rebate requires a minimum of 10 nozzles (up to 25 nozzles max can be rebated). Eligible models include popular rotary nozzles from Hunter (MP Rotators), Rain Bird, Toro, and K-Rain, among others. These nozzles throw water in steady streams that reduce misting and runoff, which is ideal for Provo’s clay-prone soils. Homeowners can submit a simple application (available on the Provo city website) to get this reimbursement after purchase.

• Backflow Prevention Rules

  Provo City code requires robust backflow prevention to guard the culinary water supply. Homeowners should ensure their sprinkler systems have an up-to-date backflow preventer (RP or PVB assembly) and get it tested each year, usually by a certified tester who files the report with the city. The city already provides a one-way check at your meter, but that alone is not enough for sprinklers or other hazards on your side of the line. By following these rules, you not only keep your own household’s water safe but also protect your neighbors and the community from accidental contamination. It’s an often overlooked but crucial aspect of maintaining a healthy irrigation system. Provo’s water officials are happy to answer questions about backflow devices and even have educational materials to help residents recognize cross-connections in their home plumbing – because preventing backflow is truly a team effort across the city.
