What supplies does a portable toilet need?
Toilet paper, hand sanitizer where the unit has a dispenser, deodorizer in the tank and fresh water for the rinse.
Toilet paper is the most used item and the first to run out. A standard unit holds a roll or a dispenser that the technician fills on each visit, and a busy unit may need a second dispenser or a fuller stock. Paper should be placed where the user can reach it from the seat, and the technician checks that the dispenser is not empty before leaving.
Hand sanitizer is a separate item. Where a unit has a dispenser, the technician fills it on each visit. Hand sanitizer does not replace handwashing. The federal construction rule requires washing facilities as well as toilets, and that requirement is met by a handwash station, which is a separate setup beside the unit.
How are supplies restocked?
On each service visit, with a stock check in between if the site is busy.
The regular visit is the restock. The technician checks each unit's paper, sanitizer and deodorizer, refills what is low, and records what was used. The record matters because it shows the restock pattern, and a site with steady use can have its stock planned against the previous visits rather than guessed.
How much stock does a busy site need?
As much as the site's use requires, which depends on the headcount, the length of the day and the weather.
A site's use is counted in people and in time. A unit used by a few people across a day needs a light stock. A unit at a fair, race or festival, where crowds arrive in waves, needs more paper and sanitizer at the start and end of each day, and a larger deodorizer load in warm weather. The provider estimates the stock from the headcount the host gives, and adjusts it after the first days.
Weather changes use. Heat increases the need for deodorizer and sanitizer, and cold changes the plan for the water in the tank, which is part of why winter visits are planned differently. A technician can talk through the stock plan for the season when the site is looked at.
Can a host restock the unit?
Usually not. The provider restocks on its visits, and the host reports what is low rather than filling the unit.
A technician restocks the unit on the route, and the host's role is to report what is low. Filling the unit from a supply the host has bought can leave the wrong product in the tank or the dispenser, and the visit record then no longer matches what the unit holds. Ask the provider what it stocks, and report what the site needs.
If the provider agrees to leave a supply at the site, that supply should be kept dry and covered, and out of the path of the truck and the walkway. Keep it where the technician can find it on the visit, and tell the technician where it is so the restock can use it.
What changes the price of supplies?
The number of units, how busy the site is, how long the term runs and how often the stock is topped up. The price is explained and approved before work starts.
Supplies are part of the service visit, so they follow the number of visits and the number of units. A busy site needs more paper and sanitizer per visit, and a site that needs an extra stop adds the time for that stop. A long term means the same restock is repeated over more weeks.
The provider quotes the supply level for the site once the headcount, the length of the event or the term and the restock schedule are known, and explains the price before any work starts. A host who wants to keep the cost down can ask for the stock to be planned against actual use, rather than a high level set in advance and left unchanged.
