Why do porta potties lean or tip in Petaluma?
Porta potties in Petaluma lean when wet clay soil softens under one corner, and they tip when afternoon wind hits an empty unit on an open lot. Winter rain from November through April and the Petaluma Gap wind cause most of the problems we fix on service visits.
The Petaluma Gap is a low break in the coast hills. Ocean air pours through it toward San Pablo Bay most afternoons, so open fields, new subdivisions and ranch yards get strong gusts.
What is the best base for a porta potty in winter?
The best winter base is pavement, a driveway or compacted gravel. On bare dirt or lawn, a 4 × 4 foot sheet of 3/4-inch plywood spreads the weight and keeps the unit level. A full 60-gallon tank adds about 500 pounds, so soft ground gives way as the week goes on.
- Pick the highest flat spot on the lot so water drains away.
- Keep the unit out of low spots near downspouts and swales.
- Keep it within 25 feet of firm ground where our truck can park.
How do you keep a porta potty from blowing over?
A porta potty stays upright in wind when it is staked or strapped and placed beside a fence, building or vehicle that breaks the wind. We stake units on open Petaluma lots at no charge when you mention the wind. Turn the door away from the gusts so it does not slam.
What about summer heat?
In summer, inland towns like Fairfield, Vacaville and Concord pass 95°F. Heat speeds up odor, so place units in shade and book a second weekly service for crews of 10 or more. In Petaluma, the afternoon breeze keeps units cooler.
