Land, Brenda . 2000. Vault Toilet Vent Gas Odor Control. 0023 1304. San Dimas, CA: U.S. Department of Agriculture, Forest Service, San Dimas Technology and Development Center. 2 p.

Vault toilet odor was the number one forest recreational visitor complaint in 1990. Extensive work went into the development of passive vault toilet ventilation principles to reduce odor in the toilet user compartment. Passive ventilation of toilet buildings (nicknamed SST toilets) is very effective in most applications at removing odors from the toilet user compartment. The vault odor is not destroyed, but removed to the outside of the building through the vent stack, sometimes having an adverse effect on the surrounding area. San Dimas Technology and Development Center (SDTDC) examined ways to minimize the odor, or the adverse effect of the odor of the vented toilet.
