What are porta-potties?

Porta-potties are self-contained toilets that are typically used in outdoor settings, such as construction sites or events. They are easy to set up and take down, and they don’t require any plumbing hookups. Most porta-potties have a holding tank that collects waste and water from the toilet bowl. The waste is then broken down by bacteria before it is flushed out of the tank. There are many different names like porta john, johnny on the spot and others. It is very common to have a porta potty rental at different events or near construction sites.

Factors influencing how often to empty a porta-potty

How often you need to empty a porta-potty depends on a few factors, such as:

  • Number of people using it: The more people who use the porta-potty, the more typically it will need to be emptied. If you have a standard porta-potty, it should be emptied every 50 uses.
  • Type of waste: If solid waste is being deposited in the porta-potty, it will need to be emptied more typically than if only urine is being deposited.
  • Temperature: In hot weather, you will need to empty your porta potty more frequently than in cooler weather. If the temperature is above 90 degrees Fahrenheit, you should empty it every 24 hours. If the temperature is between 60 and 89 degrees Fahrenheit, you can wait 48 hours between emptying. And if the temperature is below 59 degrees Fahrenheit, you can wait up to 72 hours between empties. Of course, these are just guidelines – if your porta potty starts to smell bad or looks full before the recommended time frame, it’s best to go ahead and empty it. Hotter temperatures will cause the waste to break down more quickly, so the porta-potty will need to be emptied more often in warm weather.
  • Cleaning products: Some cleaning products can help break down waste and reduce odors, which means the porta-potty won’t need to be emptied as often. Cleaning products like porta-potty blue liquids and formaldehyde helps break waste down and reduce odor, hence reducing the frequency of emptying the porta-potty.

So how often should i empty my porta-potties?

As a general rule of thumb, empty your porta-potties every 50 uses. However, there are several factors that can influence how often you need to empty them, which have already been discussed. Be sure to consider the number of people using it, the type of waste being deposited, the temperature and whether you’re using any cleaning products that could help reduce odors and break down waste. By following these guidelines your porta-potty will stay clean and functional for all your needs!

Emptying a porta-potty

The ultimate step in proper porta-potty care is emptying the unit regularly. This should be done whenever the holding tank reaches capacity – usually every few days, depending on use.

There are two ways to empty a porta-potty: manual dumping and pumping out.

Manual dumping

It is exactly what it sounds like – you open up the porta-potty and manually dump the contents into a larger holding tank. This is typically only done with small porta-potties, as larger units can be too heavy to lift.

To dump a porta-potty manually, locate the drain valve. This is usually a small hole in the unit’s bottom. Open the valve and allow all the waste to flow out. Once it’s empty, close the valve and replace the cap.

Pumping Out

Pumping out is the more common method of emptying a porta-potty, and it’s recommended for all but the smallest units. A pump truck will come to your location and attach a hose to the porta-potty. The hose sucks out the waste and pumps it into the truck, which then takes it away to be disposed of properly.

Most people prefer to pump out, as it is faster and less messy. However, if you don’t have access to a pump-out truck, then you’ll have to dump the unit manually.

To pump out a porta-potty, you’ll need access to a pump-out truck or sewage disposal facility. Contact your local sanitation department for more information about pump-out services in your area.


Porta-potties are a necessary evil. They can be stinky and gross, but they’re also a necessity outdoor venues. With proper care, you can keep your porta-potty clean and smelling fresh. And with regular emptying, you can avoid any overflow disasters.
