Allowed Watering Hours

Before 9:00 AMAfter 6:00 PM

Norman operates a permanent year-round odd/even ordinance keyed to the calendar day rather than to fixed days of the week. Sprinkler irrigation is encouraged before 9:00 AM or after 6:00 PM to minimize evaporation. Hand watering with a shut-off nozzle is permitted any time but encouraged in the same windows. The ordinance applies year-round regardless of drought stage; mandatory escalation is set in the 2021 Norman Water Conservation Plan.

🏠 HOA Rules During Restrictions

Oklahoma Residential Property Act (60 O.S. Β§851) and OK Real Estate Commission guidance establish that municipal water-conservation ordinances supersede conflicting HOA appearance requirements. Norman's permanent odd/even ordinance is a city ordinance under which HOAs cannot mandate irrigation above the allowed schedule. Document the ordinance in writing if your HOA sends a violation notice; OK Bar Association Lawyer Referral Service provides free 30-minute consultations.

If your homeowners association sends a violation notice for a dormant or brown lawn during the current restriction period, respond in writing citing the applicable law and include a copy of the City of Norman Utilities – Water Treatment Division's current restriction order. Most HOAs will rescind the notice once they are made aware of the legal protections in place. If the issue persists, contact your county’s code enforcement division for assistance.

Why These Restrictions Exist

Norman is served by the City of Norman Utilities Water Treatment Division and operates a permanent year-round odd/even outdoor-irrigation ordinance. Source water: Lake Thunderbird (the primary supply, constructed 1962-1965 by the US Bureau of Reclamation specifically to serve Norman, Del City, and Midwest City) plus city groundwater wells in the Garber-Wellington Aquifer plus supplemental wholesale supply from the Oklahoma City Water Utilities Trust system.

Statewide context: Oklahoma is in active drought. Oklahoma County (north of Norman in Cleveland County) is in D2 Severe Drought; Cleveland County is tracking D1 Moderate to D2 Severe per the US Drought Monitor. The February 2026 Ranger Road Fire (283,283 acres – the largest US wildfire of 2026) drove regional burn bans across central and eastern Oklahoma. Lake Hefner (OKC's primary supply, drawn on by Norman as a supplemental tie-in) stands at 54% of capacity.

Lake Thunderbird local context: the lake has known historical vulnerability to harmful algal blooms and sediment accumulation. Norman's water-quality monitoring program coordinates with the Central Oklahoma Master Conservancy District (which operates Lake Thunderbird itself). Outdoor irrigation conservation directly extends the buffer on lake drawdown during summer peak demand.

The University of Oklahoma (OU – roughly 28,000 students) and the National Weather Center / NOAA Storm Prediction Center are major federal and institutional water consumers within city limits, on separate institutional accounts with Norman Utilities.

Rainfall Deficit: Lake Hefner 54% (regional supplemental supply) Β· Cleveland County D1-D2 drought

This deficit has accumulated over the current water year and represents a significant departure from historical averages for the Norman area. Water supply reservoirs and aquifer levels are well below seasonal targets, necessitating mandatory conservation measures.

How to Keep Your Lawn Alive During Norman Water Restrictions

11 tips tailored for Norman homeowners during Permanent Year-Round Odd/Even Schedule restrictions.

Norman's permanent odd/even ordinance is calendar-day-based: odd-numbered addresses water on odd calendar days, even on even days (not fixed days of the week like Mondays/Thursdays).

Hand watering with a shut-off nozzle is permitted any day but is most efficient before 9 AM or after 6 PM – Norman summer afternoons drive 30%+ evaporation losses on mid-day irrigation.

Bermuda dominates Norman lawns and is best suited to the permanent odd/even framework; tall fescue browns severely under Norman summers without supplemental irrigation.

Cycle-and-soak on Norman's red clay soils: 8 minutes on, 30-minute pause, 8 minutes on – prevents the immediate runoff that follows continuous spray on clay.

Mulch ornamental beds 3 inches deep with arborist wood chips; bare soil in Norman's July heat loses 0.5+ inches of moisture per day.

Drip-irrigate trees, shrubs, and vegetable beds – drip is exempt from the odd/even calendar-day ordinance and uses 30 to 50 percent less water than overhead spray.

Audit sprinkler heads monthly for overspray onto sidewalks and driveways; visible runoff violations are cited under Title 19 of the Norman Municipal Code.

Skip your assigned watering after any 0.25 inch or greater rainfall in the prior 48 hours – Oklahoma rain sensors are required on systems installed after 2010 under city building code.

Replace narrow parkway strips with Oklahoma natives (Buffalo Grass, Indian Grass, Little Bluestem) – low-irrigation conversion targets that align with Norman's water-conservation rebate program.

Track monthly use at normanok.gov MyAccount; the Norman Utilities portal flags high-use months for follow-up.

Harvest rainwater off downspouts into rain barrels – Oklahoma law permits residential capture without restriction and barrel water is exempt from the odd/even schedule.

Norman Water Restriction FAQs

Your watering day in Norman depends on your street address. Addresses ending in Odd can water on Odd-numbered calendar days only. Addresses ending in Even can water on Even-numbered calendar days only. You are limited to 3 days per week during the current Permanent Year-Round Odd/Even Schedule restrictions.
What hours can I run my sprinklers in Norman?

Norman operates a permanent year-round odd/even ordinance keyed to the calendar day rather than to fixed days of the week. Sprinkler irrigation is encouraged before 9:00 AM or after 6:00 PM to minimize evaporation. Hand watering with a shut-off nozzle is permitted any time but encouraged in the same windows. The ordinance applies year-round regardless of drought stage; mandatory escalation is set in the 2021 Norman Water Conservation Plan. Watering outside these hours, even on your scheduled day, is a violation and may result in a citation.
What are the fines for water violations in Norman?
City of Norman Utilities issues citations under Title 19 of the Norman Municipal Code. First-offense violations of the odd/even ordinance typically draw a $100 citation; repeat violations escalate per the 2021 Norman Water Conservation Plan. Commercial and irrigation-system installer violations carry separate higher penalties. The City of Norman Utilities – Water Treatment Division and local Cleveland County enforcement officers conduct patrols and respond to complaints. Keep your irrigation timer set to your assigned day and hours to avoid citations.
Can I install new sod or seed in Norman during restrictions?
New sod installations receive a 21-day establishment variance from Norman Utilities. Lake Thunderbird's known algal-bloom and sedimentation vulnerability has made Norman one of central Oklahoma's most conservation-active utilities; turf-replacement guidance is published at normanok.gov.
When will water restrictions end in Norman?
The current Permanent Year-Round Odd/Even Schedule restrictions in Norman are effective from Permanent ordinance through Permanent ordinance. However, the restrictions may be extended if drought conditions persist or eased if significant rainfall improves water supply levels. Monitor the City of Norman Utilities – Water Treatment Division website for updates.
I'm in Norman but my water bill says OKC Water Utilities Trust – different rules?
Yes. A small share of Norman addresses on the city's far-north edge receive wholesale water through the Oklahoma City Water Utilities Trust rather than directly through City of Norman Utilities. OKC Trust customers follow the OKC permanent seasonal odd/even ordinance (Monday/Thursday for odd, Tuesday/Friday for even, April 1 through October 31, no Saturday/Sunday irrigation, 10 AM – 6 PM blackout) rather than Norman's permanent year-round calendar-day-based odd/even ordinance. Read the top of your water bill to confirm – Norman Utilities customers see 'City of Norman' on the bill header, while OKC Trust customers see 'Oklahoma City Water Utilities Trust' or 'OKC Water'.
University of Oklahoma dorms – does the university follow Norman's residential schedule?
OU campus housing (residence halls, on-campus apartments, fraternity/sorority houses) is not separately metered – the university operates under institutional water accounts with City of Norman Utilities that fall under the same permanent odd/even ordinance as residential customers. Campus athletic-field irrigation (Owen Field, Bedlam baseball complex, OU Soccer Stadium) holds variance review under Title 19 Β§22 of the Norman Municipal Code for game-week preparation, but the default is the residential odd/even framework. Indoor potable use is not subject to the outdoor schedule.
Lake Thunderbird is shared with Midwest City and Del City – do we all have the same rules?
Same source water (Lake Thunderbird, constructed 1962-1965 specifically to serve all three cities), but different retail ordinances. Norman runs a permanent year-round calendar-day-based odd/even schedule. Midwest City and Del City run their own ordinances under separate municipal codes and may differ in fixed days of the week, mid-day blackout hours, and fine schedules. The Central Oklahoma Master Conservancy District operates Lake Thunderbird itself and coordinates drought-stage triggers across the three cities, but each city sets its own retail rules within the conservancy's broader framework. Lake Thunderbird's algal-bloom and sediment vulnerability is the shared regional concern that drives all three cities' conservation programs.
National Weather Center / NOAA federal facility – same water rules as my Norman home?
The National Weather Center campus on OU's South Research Campus (which houses the NOAA Storm Prediction Center, NSSL, and several NWS units) holds a federal institutional water account with City of Norman Utilities. Federal facility landscape irrigation aligns with the residential odd/even calendar-day ordinance in practice, though operational uses (HVAC cooling water for the supercomputer cluster, lab process water) are governed by separate federal facility permits and are not subject to the residential schedule. The campus is on the same Lake Thunderbird source water as the rest of Norman.
