Vault toilets are non-flush toilets that store waste in a big airtight subsurface tank without using water (vault). This kind of toilet differs from regular flushing toilets in that it is built in locations where water is scarce, such as leisure and public places, tents, and other shared spaces. Vault toilets are also known as campground toilets since they are commonly found at campgrounds. Water-based toilets also include pit toilets, composted toilets, and sack toilets.
The decline in water costs and contamination are the two main advantages of such toilets. These toilets use the least amount of energy and are excellent compact toilets for small settings. The restrooms are ADA-compliant in terms of toilets and environmental benefits. Unless a strong wind is present, they are odorless. You can literally sit out in it without breathing air.
Vault toilets do not utilize water or cleaning but instead store waste in a big, sealed container beneath the ground. The subsurface container is referred to as the ‘vault’ in the vault toilet. This toilet style is ideally suited to regions with limited access to water, such as shared spaces, campgrounds, playgrounds, and outdoor spaces.
They were developed by the US Forest Service to lessen reliance on standard American toilets and were authorized by the ADA. They’re simple to build and can be fashioned out of cross-linked polyolefin, plastic, concrete structures, or wood frames. In addition, they’ve proven to be extremely robust, with polyethylene being the most frequent material.
Because the components used to make vault toilets generally crack, they pose a low danger of pollution. In addition, the adoption of a more compact vault toilet, such as one made of plastic, makes it lighter and more portable. Composting toilets, pit toilets, and bag toilets are examples of other waterless toilets. You can also read our guide of Pit Toilet vs Vault Toilet here.
How does it work?
The vault, which is buried into the earth, and the upper half, which resembles a booth, are the 2 components of a traditional vault toilet. These toilets are designed for both men and women and can be set up quickly for gatherings or other activities. The underground vault may hold anywhere from 1,000 to 13,000 gallons of water.
The earth is excavated to satisfy the vault’s size and shape when building a vault toilet. The vault is then buried underground, with a slab covering the top to provide support. The toilet is frequently built on a slope to allow for the optimum waste flow. A structure is made to the surface during construction to give a link to the vent tube. After that, the upper part is built on a sloped surface.

When the vault gets close to becoming filled, the town council or another service can empty it. Most vault toilets are flushed once a week or every two weeks, based on the size of the vault and the utilization rate.
When it comes to managing toilet odors, there are a few external variables that must be considered. To begin, the vent must be taller than the toilet booth’s roof. Aside from that, the odor must be carried away by the wind; otherwise, it will condense from around the toilet or collect in a nearby building.
The following are some other options for releasing the vault toilets:
- Using a flame to burn the scents from the toilet vapours out of the vent.
- Long subterranean pipes can transport trash to locations distant from the toilet. This is usually utilized for vault toilets that are built to last.
- With the introduction of an organic filler to the trash, the smell in the odour, made up of carbon dioxide and hydrogen sulphide, can be transformed into odourless nitrogen gas.
- To reduce the stink from the toilet vapours, activated carbon can be applied to the excrement.
The accessibility of heat on the exhaust at the toilet’s ceiling is another key factor in minimizing the odor from a vault toilet. The sunlight is usually sufficient for this cause. When the head of the valve is heated, the unpleasant smell is swiftly forced out. Due to the fact that hot air is lighter than cold air, heated air rises swiftly and away from people. You may have observed that sewer gases are more noticeable on chilly days than on warmer days.
Advantages of Using a Vault Toilet

Disadvantages of Using a Vault Toilet
The atmospheric process will be ineffective if the exhaust lacks heat at the top. Cloudy weather, rain, crowds, or perhaps even shade from trees and branches can all contribute to this. There have been instances where the vault toilets’ ventilation has failed. However, this is unusual. The air from around the toilet will be saturated with a foul odor in this situation.
