Bottom line

Operator-friendly model; diligence should focus on acquisition price.

Portable sanitation rental is a recession-proof, essential-service business. You buy or lease portable toilets and rent them to construction sites, outdoor events, and festivals. Routes are serviced weekly with a pump truck. Once you build a route, recurring revenue is remarkably stable.
