How Does a Mobile Toilet Drain Waste

The waste drainage methods of mobile toilets mainly fall into two categories: direct drainage and collection and treatment using a fecal tank.

Direct Drainage Method

Direct-drainage mobile toilets are connected directly to a sewage pipe for waste discharge. The sewage outlet is typically located at the rear of the toilet. During installation, a sewage pipe with a diameter of 110 and an inlet water pipe with a diameter of 25 are required. Once the sewage pipe is connected to the ground, the mobile toilet can be used normally. This drainage method is suitable for locations with a well-established sewage pipe system, such as some large event venues. If there are municipal sewage pipes nearby, direct-drainage mobile toilets can be used. They can quickly and directly discharge fecal wastewater into the designated sewage pipes, with high treatment efficiency. This reduces the storage time of fecal wastewater inside the toilet, lowers the possibility of odor generation, and ensures a relatively clean internal environment of the toilet. However, the direct-drainage method has certain requirements for the installation environment; there must be an accessible sewage pipe, otherwise, it cannot be used normally.

Using a Fecal Tank

Mobile toilets that use a fecal tank collect and treat fecal wastewater through a fecal wastewater storage tank. Such mobile toilets are generally composed of multiple parts, with the fecal wastewater storage tank (or fecal wastewater treatment device) being one of the key components. After people use the toilet, the fecal wastewater flows into the storage tank. The storage tank has a certain capacity, and an appropriate size can be selected based on the number of users and the usage time. In locations with low usage frequency or without sewage pipes, such as remote scenic spots and wild construction sites, mobile toilets with fecal tanks are very suitable. They do not rely on external sewage pipes and can operate independently. Moreover, some mobile toilets are equipped with fecal wastewater treatment devices that can perform certain treatments on the fecal wastewater in the storage tank, such as sedimentation and decomposition, reducing odor and pollutant emissions and minimizing the impact on the environment. When the storage tank is nearly full, specialized personnel need to be arranged for cleaning and transportation, taking the fecal wastewater to a designated treatment site for further processing.
