Mobile Toilet Fecal Storage Tank

Admin September 26, 2026

The fecal storage tanks of mobile toilets vary depending on their types. Some mobile toilets come with built-in fecal tanks, while others, as integrated products, have built-in septic tanks. There are also some that do not require septic tanks at all.

Some mobile toilets come with built-in fecal tanks: Certain mobile toilets, such as some mobile restrooms, are equipped with both fecal and water tanks. The dimensions of the fecal tank are typically 1.1 meters in length and width, and 2.3 meters in height, made of polyethylene plastic. Polyethylene plastic offers advantages such as corrosion resistance and excellent sealing, effectively storing fecal wastewater and preventing leaks and odor emissions. This built-in fecal tank design allows mobile toilets to operate without relying on external septic tank facilities, facilitating deployment and use in various locations, especially suitable for temporary event venues and construction sites.

Some integrated mobile toilet and restroom products come with built-in septic tanks: There are also integrated mobile toilet and restroom products on the market that come with built-in septic tanks. The design of the septic tank enables further treatment of fecal wastewater through processes such as sedimentation and fermentation, breaking down organic matter in the feces and reducing the volume and harmful substances in the wastewater. This integrated design enhances the functionality of mobile toilets, better meeting long-term usage needs and reducing environmental pollution to a certain extent.

Some mobile toilets do not require septic tanks: Not all mobile toilets require septic tanks. Some mobile toilets that employ advanced treatment technologies, such as those equipped with fecal wastewater treatment devices, can directly treat fecal wastewater to meet discharge standards or make it recyclable, eliminating the need for septic tanks. This design not only saves space and costs but also improves the usage efficiency and environmental performance of mobile toilets.
