Edmond has already published your water bill through 2029. An average residential customer paid $149.81 a month starting July 2026. That figure is scheduled to reach $168.08 in 2027, $171.58 in 2028 and $175.28 in 2029, according to the City of Edmond's announcement of the rate increase. The reason behind that schedule shows up every summer in the city's front yards.
During low-use periods, Edmond's water system serves a city that uses 9 to 13 million gallons a day. In August 2026, demand passed 22 million. The whole rate plan, the $377 million construction contract behind it, and the rule that decides which days you can run your sprinklers all come from the effort to close that gap. If you're comparing Edmond with Moore, Yukon or Norman, the true cost of an Edmond house includes your share of that gap.
The summer number that sizes the system
On August 19, 2026, the Journal Record reported that Edmond typically uses between 9 million and 13 million gallons of water per day during low-use periods, and that demand had recently topped 22 million gallons per day. City Manager AJ Krieger pointed to higher-than-normal temperatures, below-average rainfall and rising demand on the system.
Compare that with what the city can treat on its own. Edmond's 2024 Water System Master Plan Update says the original Arcadia Lake intake and treatment plant hydraulics were capped at 11.0 million gallons per day, leaving "no room to expand." More recent reporting from June 2026 puts the existing plant at 12 million gallons per day. Whichever figure you use, an August day in 2026 called for roughly twice what the plant was built to handle.
Arcadia Lake itself holds more than the plant can process. A yield study raised the lake's estimated supply from 11 to 17.6 million gallons per day. The city's plan points out that both figures are annual averages, not peak-day numbers, and that the lake works as storage for summer peaks. So the lake has the water. What Edmond lacks is a plant big enough to treat August's demand.
Why Oklahoma City stopped being the backup plan
For more than 25 years, Edmond covered the difference by buying water from Oklahoma City. The master plan says that in the late 1990s the city built a pipeline and a northwest pump station "to purchase water from OKC for our peak water use (outdoor use)." The city's own planners wrote "outdoor use" into that sentence. Edmond's backup supply existed to keep summer lawns watered.
The same document explains why that arrangement no longer works:
"Since then, the water supply contract and rates with OKC have changed making it much more advantageous in the long term to build our own infrastructure as OKC will no longer serve only peak water use. We would not allow that type of use on our system, and they are right to take that position."
That is the mechanism behind your bill. A supplier that sells you water only during the hottest weeks of the year carries the cost of capacity that sits idle the rest of the year. Oklahoma City decided not to keep carrying that cost for Edmond, and Edmond's own planners agreed with the decision. Edmond now pays for that peak capacity itself, and the cost reaches every customer through the base rate.
What $377 million buys, and who pays for it
On June 22, 2026, the Edmond Public Works Authority voted 4-0 to approve borrowing authority of up to $416 million through the Oklahoma Water Resources Board, along with a $377.2 million construction contract for the Arcadia Lake Water Treatment Plant WTP-01C Process Improvements Project. The City Council approved its side of the financing, also 4-0. The project replaces the existing plant and expands treatment capacity from 12 to 30 million gallons per day, which puts it comfortably above the 22 million gallon days of this past August.
According to Edmond Inbox's coverage of the vote, the city received one bid, and the agenda packet named Archer Western Construction as the recommended contractor. The contract depended on the financing loan closing successfully. Consultant materials assume the work runs from June 2026 through July 2030. That is a planning assumption and could change.
Council member Preston Watterson explained the loan approach this way: a project this large should be paid for over time by current and future users, not placed entirely on today's ratepayers. For a buyer, that line matters. Spreading the cost over time means anyone who buys in Edmond during the next several years is one of those "future users." The loan is structured to share the bill with people who haven't moved in yet.
There are two more details from that meeting. Watterson said $416 million is a ceiling, not necessarily the final amount borrowed, and that the city didn't plan to revisit or raise rates at that time. Mayor Mark Nash said the council had agreed to review the rate picture over the next two years to see whether rates could come down if project conditions allow.
The bill schedule, laid out
The city's example customer has a 5/8-inch meter and uses 8,000 gallons of water and 5,000 gallons of wastewater a month, which the city describes as average residential use. The base-rate increases approved on May 11, 2026 work out like this:
- July 2026: combined base rates up $18.06 a month, for a $149.81 example bill
- July 2027: up another $18.27 a month, for $168.08
- 2028: up a projected $3.50, for $171.58
- 2029: up a projected $3.71, for $175.28
Subtracting the first increase from the July 2026 figure puts the same household's bill at about $131.75 before the change. Under the schedule, a typical bill rises by about $43.50 a month over four years, with most of that coming in the first two. These are increases to the monthly base rate. That makes them a fixed cost of having the service. They apply whether a yard is green or brown.
The city ties the money directly to the plant. Its announcement says the rates will help replace "an outdated and increasingly less reliable 1980s facility" and that expanding the Arcadia Lake plant moves Edmond "away from a reliance on paying to purchase water from Oklahoma City."
Your address decides which days you can water
The second cost of summer demand comes as rules. Edmond's Water Conservation Plan has five stages. The baseline, Stage One, is year-round mandatory odd/even lawn watering. When demand hit 22 million gallons a day in August, the city moved to Stage Two. That replaced odd/even watering with two lawn-watering days a week, one weekday and one weekend day, assigned by the last digit of the address. KFOR reported that odd-numbered addresses got Saturday and Wednesday, even-numbered addresses got Sunday and Thursday, and businesses and HOAs got Tuesday and Friday.
On September 28, 2026, citing cooler forecasts and recent rain, the city returned to Stage One, which is the rule in effect now.
Reports on enforcement during Stage Two didn't fully agree. The Journal Record said first-time violators would get a warning and repeat violators might be cited. News 9 described the same warning-then-citation approach. KFOR reported that no citations were being issued at the time and that code enforcement might leave a reminder after a complaint. Either way, the schedule applies to every irrigated yard in the city, and it gets tighter in exactly the weeks when a lawn needs water most.
The city also says most lawns can stay green and healthy when watered every three to four days, and that watering less often encourages deeper roots. A yard planted and irrigated with that in mind handles a Stage Two summer much better than one that has been watered daily.
What this changes when you compare an Edmond house
Edmond is a good market for asking questions right now. The MLSOK report for Edmond city single-family homes showed 1,109 homes on the market in August 2026, up 29.6% from a year earlier, with a median of 39 days on market. More homes for sale and more time on the market give a buyer room to look into the yard as carefully as the kitchen. Here's what to look at on an Edmond property:
- The irrigation controller. Check whether the sprinkler system can be set to the odd/even schedule and switched to a two-day weekly schedule without rewiring or replacing the controller. The rule follows the address, so a home's watering days come with the house.
- Recent water bills. Edmond residents can see their usage through the city's Smart Choice portal. A seller's July and August bills from 2026 show what that particular lot actually used under this year's rates and restrictions.
- How much of the lot is turf. The base-rate increases fall on every account. A large irrigated lawn adds usage charges on top of those increases, and it's also the kind of demand that set the system's peak this summer. The city's Conservation University pages include a drought-tolerant plant database.
- HOA common areas. Under Stage Two, HOAs had their own watering days, Tuesday and Friday. In neighborhoods with irrigated entrances or medians, the HOA's water costs eventually show up in its dues.
When you compare Edmond with another suburb, keep in mind that this cost is published in advance. Few cities print four years of expected water bills. In Edmond, the increases are already on the record, and the plant they pay for is designed to bring the city's summer demand within its own treatment capacity.
A short FAQ
Are Edmond's watering restrictions in effect right now? Stage One, year-round odd/even lawn watering, has been in effect since September 28, 2026. The two-day Stage Two schedule ran from August 19 until then. The current stage is posted on the city's Water Resources page.
Could the scheduled rate increases change? The schedule approved in May 2026 runs through 2029. At the June 22 financing vote, the mayor said the council would review rates over the next two years to see whether they could be reduced if project conditions allow.
When is the new plant expected to be finished? Consultant materials from June 2026 assume construction from June 2026 through July 2030. That is a planning assumption, not a promised completion date.
Is there help for households struggling with the higher bills? The city lists assistance options through the HOPE Center of Edmond, the Oklahoma 2-1-1 Resource Directory and OKDHS on its Programs & Resources page.
