Porta Potty Service Proof: GPS, Photos, and Combo on File
How to stop “service complete” lies on construction toilets - combo codes, GPS, photos, and an honest miss when the truck cannot get in.
· 6 min read

Construction supers in Prince George's County, Washington DC, and Montgomery County do not complain about the existence of portable toilets. They complain that a scanner said the unit was serviced when the tank is still full. Proof of service is the product. The cabin is just the box it happens in.
Combo on file

If the unit is locked, the tech needs the code without a scavenger hunt. Put the combo on the account at delivery. Update it when the GC changes locks. A company that emails you the same day they could not get in is worth more than one that marks the visit complete from the street.
GPS and photo
- GPS confirms the truck was at the pad, not two sites over
- A photo of the serviced interior ends the argument with payroll and the trades
- Time stamps belong on the ticket you can pull when a sub says the unit was skipped
Honest miss beats a fake complete
Mud, a parked dumpster, or a missing gate code will happen. The 5-star pattern is simple: tell the site contact immediately, keep the unit on the next-day make-up list, and do not invoice a service that did not occur. Crews forgive a weather miss. They do not forgive a lie.
FAQ
What should a service ticket include?
Date, tech, unit IDs, what was pumped and restocked, and either a photo, GPS ping, or both. If the pad was blocked, the ticket should say so the same day.
Why does a combo on file matter?
Techs who do not have the lock code skip the stop or cut the lock. Storing the combo on the account is the difference between a real clean and a drive-by.
