Does Riverton have secondary water?

Yes, Riverton has secondary water, and the city says it serves all residents. The usual schedule runs from about May 1 to October 15, with 2026 water arriving around May 5.

Riverton City runs a pressurized irrigation system that “provides outdoor irrigation water to all residents” (Riverton City, Secondary Water, checked October 2026). In Riverton the question is not whether a house has secondary water. It is how the schedule, the rules and the bill work once you own one.

The Riverton secondary water schedule

The city describes the season as running from approximately May 1 through October 15 each year. Treat both ends as estimates.

The start date is not Riverton’s to set. The city says the actual start is decided by the four canal companies that supply its secondary water, and it varies from year to year. In her April 1, 2026 message, Mayor Tish Buroker said the canal companies were expected to begin releasing water into the canals around April 15, that filling the ponds and pipes would take about two weeks, and that water would reach residents around May 5. She added that homes on the west side of Riverton might see water sooner, as the city’s well is engaged (Riverton City, Mayor’s Message, April 1, 2026).

The fall end is the same kind of estimate. Plan on mid-October and do not count on watering a new lawn into November.

The March 15 valve deadline is the one new owners miss

Riverton puts the valve on the homeowner. Each resident is responsible for turning off their individual secondary valve no later than March 15. After that date, city crews start maintenance and testing, and the city warns that valves left open may be damaged, flooding may occur, and the city is not responsible for the damage.

The city’s council message on metering explains the yearly routine: open the ball valve in the green irrigation box in the fall so water drains out and the lines do not freeze, then close it in the spring so canal water can fill the pipes (Riverton City, Council Message on Secondary Water Meters). The T-wrench stop-and-waste valve in the park strip is the city’s, not yours.

If you are buying a Riverton house in winter, ask the seller where the irrigation box is and whether the valve was opened for the season. I tell clients to put a March 15 reminder in their phone the day they close.

Is there a watering schedule or assigned days

No assigned days, and no current drought restrictions, but there is a time-of-day rule.

The city’s metering FAQ says plainly that watering is prohibited between 10 a.m. and 6 p.m. because of evaporation (Riverton City, Secondary Water Metering Project, checked October 2026). Separately, the city’s secondary water page says Riverton does not currently have water restrictions in place and asks residents to conserve: trim sprinkler output by 10 to 20 percent, turn sprinklers off when rain is forecast, and let the lawn go slightly brown in dry spells.

Assigned days have happened before. In August 2016, with Utah Lake low enough that the state engineer could cut off secondary-right users, Riverton asked homes east of 2700 West to water Monday, Wednesday and Friday, homes west of it to water Tuesday, Thursday and Saturday, and everyone to leave secondary water off on Sundays (Deseret News, August 2016). That was a drought response, not a standing rule. It is a fair picture of what a bad water year looks like here.

Where the water comes from, and why a dry year matters

Riverton’s system was built in the early 2000s and includes 182 miles of pressurized irrigation pipe, 2,581 valves, three reservoirs and water shares in the Jordan River, according to the mayor’s April 2026 message. The water arrives through canals, the Jordan River and a well. The canals draw mainly on Utah Lake, which depends on reservoirs and mountain snowpack. That is a district arrangement rather than something you own, which is close to the opposite of how water shares work in Utah.

That chain is why the season can shorten. In the same message the mayor noted Deer Creek was 80 percent full and Jordanelle 60 percent full, with little further filling expected because of thin snowpack. In 2016, a toxic algae bloom forced Riverton to shut its secondary system for a period earlier in the summer, before the low-lake-level scare, according to the Deseret News.

None of that makes Riverton’s secondary water unreliable. It makes it seasonal and weather-dependent, which is the honest way to describe any canal-fed system in Utah.

What Riverton secondary water costs

Riverton bills secondary water by lot size, not by how much you use. The city’s water rates page, checked October 2026, lists a base rate of $3.05 per meter for single-family and duplex homes, plus a lot-size charge:

• Up to 0.25 acres: $23.62
• 0.26 to 0.33 acres: $27.97
• 0.34 to 0.50 acres: $34.99
• 0.51 to 0.74 acres: $42.83
• 0.75 acre and above: $49.86

(Riverton City, Water Rates, checked October 2026). Indoor culinary water is billed separately, on a tiered consumption rate.

Two things follow from a lot-size bill. First, a large yard does not cost more to water in July than in May, so the secondary charge is predictable in a way a metered bill is not. Second, the lot size on record is what sets your charge, so check that the acreage on the county record matches the house before you assume which tier you are in. Utility Billing is on 801-208-3133.

Meters are in, and they change what you see, not what you pay

The 2019 Utah Legislature required secondary water suppliers to plan for metering, and Riverton installed a meter on every connection; the city’s FAQ says it is not optional. As of the mayor’s April 2026 message, the four-year installation project was basically complete apart from some smaller residential areas. The meters are read remotely by radio.

The point, in the city’s words, is awareness. Bills show each property’s actual secondary use alongside a recommended amount, and the city says rates are not anticipated to change because of the project (Riverton City, Why Secondary Water Meters, checked October 2026). The reason it cares is on the same page: the system was designed for roughly 19 to 20 million gallons a day at full build-out, and peak summer use had reached 30 to 35 million gallons a day, with some residents reporting lower pressure on peak days.

My read is that a lot-size bill with a usage line printed under it is a system halfway to something else. Nothing on the city’s pages says that change is coming. If you are buying a house with a big lawn on the assumption the bill will never move, keep the assumption loose.

What a buyer should check on a Riverton house

The city says the system serves all residents, so the checks are mostly about condition and rules rather than availability. Still confirm the specific address has a connection.

• The personal shut-off valve. The city says every irrigation system needs one, and it no longer replaces broken ball valves for residents.
• A filter. Secondary water is not treated or filtered and can plug sprinkler heads; the city recommends a filter on the system.
• Who owns which pipe. The city is responsible up to and including the stop-and-waste valve or the secondary meter. From there into the property, the line is the owner’s.
• No unauthorized connections. Using the city’s secondary water without the required inspections and monthly fees is a Class B misdemeanor, with fines of up to $1,850 per day of violation, per the city.
• Larger parcels. On Riverton’s bigger lots, water rights and irrigation shares are a separate subject from the city system; the best neighborhoods in Riverton covers what to ask.

Note: This is general information, not legal advice. City rules and rates change by ordinance; confirm the current code and fee schedule with Riverton City before relying on them.

How Riverton compares with Herriman

The contrast with the next city south is sharp. Herriman’s secondary system reaches only part of the city, so in Herriman the first question is whether the address has it at all, and its water rates depend on pressure zone, meter size and secondary access. Do Herriman homes have secondary water covers that. In Riverton the city says the system serves all residents, and the bill follows the lot.

For buyers weighing the two cities on everything else, Herriman vs Riverton is the wider comparison, and what it is like living in Riverton covers the rest of daily life there.

The short version

Riverton City says its secondary system serves all residents, billed by lot size. One wrinkle worth flagging: in a community like Monarch Meadows, where townhome dues reportedly include water, establish exactly which water that covers before you assume your irrigation is handled. The season usually runs from about May 1 to October 15, set by the canal companies; in 2026 water arrived around May 5. Close your valve by March 15, do not water between 10 a.m. and 6 p.m., and there are no assigned days unless a drought year brings them back.
