Keeping Porta Potties Fresh in Oklahoma Summer Heat
July in Oklahoma City averages a high of about 93°F, and heat speeds up odor in any portable toilet. Shade, the right service schedule and enough units make the difference between a unit guests use and one they avoid.
| Situation | Service plan | Placement |
|---|---|---|
| Crew of 15+ per unit in July | 2 services a week | Shade on the north or east side |
| Event over 4 hours, 90°F+ | Add 1 unit per 150 guests | Downwind, away from food |
| Wedding in July or August | Restroom trailer with A/C | Dedicated 20-amp circuit |
| Food served outdoors | 1 hand washing station per 3 toilets | Next to the food line |
How hot does it get in Oklahoma City in summer?
Oklahoma City averages a July high of about 93°F under NOAA 1991–2020 normals for Oklahoma City, and the record is 113°F. Highs in the 90s are normal from June through early September. Inside a dark plastic unit in full sun, the air can feel 15 to 20 degrees hotter than outside.
How do you keep a porta potty from smelling in the heat?
Keep a porta potty fresh in the heat by placing it in shade, keeping the roof vent clear, adding service visits for busy sites, and ordering enough units so no single tank fills too fast. A unit that is used less and serviced more stays fresh even in July.
- Shade: the north or east side of a building, or under trees with high limbs
- Service: twice a week for crews over 15 in July and August
- Count: add 1 unit for every 150 guests at events longer than 4 hours
- Upgrade: a restroom trailer with A/C for weddings
Do summer events need more hand washing?
Summer events need more hand washing, because guests sweat, eat outside and drink more. Plan 1 two-sink hand washing station for every 3 toilets, and put one next to any food line. Stations get refilled at each service visit, so long events should add a mid-event visit.
