Mobile Toilet Sewage Tank

The sewage tank for mobile toilets is a crucial component used for storing fecal sewage in mobile toilets. It comes in various types, and its price varies depending on the configuration and model.

Basic Composition and Function of the Sewage Tank

Mobile toilets are generally composed of fecal sewage storage tanks (or fecal sewage treatment devices), among other parts. As one of the core components, the sewage tank's main function is to collect and store the fecal sewage generated during use, preventing direct discharge from polluting the environment and facilitating subsequent centralized treatment or transfer.

Types of Sewage Tanks

• Vehicle-mounted Sewage Tanks: These are commonly found in mobile toilet vehicles, such as those in Suizhou, Hubei. The sewage tanks configured in these vehicles have a relatively large capacity. For example, a restroom with 8 - 12 stalls can be equipped with a 500L sewage tank. These sewage tanks are usually designed integrally with the vehicle, making them easy to move and transport. They are suitable for large-scale events, construction sites, and other places with high personnel turnover.
• Portable Sewage Tanks: For instance, the sewage tank used in the 2026 new model of portable plastic mobile toilets often adopts a gravity flushing design and is equipped with a foot pump. These sewage tanks are made of lightweight materials, making them easy to install and dismantle. They are suitable for temporary and small-scale usage scenarios, such as outdoor camping and small exhibitions.

Factors Affecting the Price of Sewage Tanks

The price of sewage tanks is influenced by multiple factors, including material, capacity, and configuration. Taking the mobile toilet vehicle in Suizhou, Hubei, as an example, the price of a restroom with 8 - 12 stalls equipped with a 500L sewage tank is 480,000 yuan per vehicle. This price includes not only the sewage tank itself but also other components and the overall design of the toilet vehicle. In contrast, the sewage tank of a portable plastic mobile toilet is relatively cheaper due to its simpler material and design.

Maintenance and Management of Sewage Tanks

To ensure the normal use and extend the service life of sewage tanks, regular cleaning and maintenance are required. When cleaning, the sewage in the tank should be emptied and rinsed thoroughly with clean water. If necessary, a disinfectant can be used for disinfection. At the same time, the tightness of the sewage tank and the integrity of its connecting components should be checked to prevent leakage problems.
