Porta Potties and Santa Ana Winds: How to Keep Units Upright

Can wind knock over a porta potty?

Strong wind can knock over a porta potty that stands alone on open ground, especially when the tank is nearly empty and the unit is light. Gusts of 50 mph or more during Santa Ana events are enough. A tipped unit spills, so prevention matters.

Which areas around Chino get the strongest winds?

The strongest winds near Chino hit Fontana, Rialto and north San Bernardino below the Cajon Pass; Etiwanda and north Rancho Cucamonga; Beaumont and Banning in the San Gorgonio Pass; Anaheim Hills at Santa Ana Canyon; and open lots in Ontario Ranch. High Desert sites see wind most of the year.

How do you anchor a porta potty?

We anchor porta potties with ground stakes through the base or ratchet straps to a fixed object like a fence post or wall. On pavement, we strap to a structure or set the unit in a sheltered corner. Units in a row can be strapped together.

Where should I place a unit on a windy site?

Place the unit beside a wall, building or parked container, with its back to the prevailing wind so the door does not catch. Avoid open ends of driveways and gaps between buildings where wind funnels. Keep it away from dry brush during red-flag warnings.

See the placement guide for space and access rules.
