What is the Size of the Sewage Outlet for Mobile Toilets?
There is no unified standard for the size of the sewage outlet for mobile toilets, as it varies due to multiple factors. The common diameters generally range from 100 millimeters to 150 millimeters.
Common Size Range
In most cases, the diameter of the sewage outlet for mobile toilets falls within the range of 100 millimeters to 150 millimeters. Among them, small and simple mobile toilets, due to their relatively small number of users and simpler overall facilities, have lower requirements for sewage discharge capacity. Therefore, the diameter of their sewage outlets may be 100 millimeters. This size can meet their basic sewage discharge needs during daily use while also saving materials and space to a certain extent.
For larger mobile toilets with more users or complete facilities, their sewage discharge needs increase accordingly. To ensure timely and smooth discharge of feces and other waste, avoiding issues such as blockages, the diameter of the sewage outlet may reach 150 millimeters. A larger sewage outlet provides a more ample passage, allowing waste to pass through more quickly and reducing the possibility of accumulation in the pipes.
Special Case Sizes
When a mobile toilet is connected to a septic tank for direct discharge, the requirements for the size of the sewage outlet differ. In this case, the sewage outlet can be opened to a 250-millimeter pipe eye. This is because when connected to a septic tank for direct discharge, a stronger sewage discharge capacity is required to handle a large amount of waste discharge. A larger pipe eye ensures that waste can smoothly enter the septic tank, reducing the risk of blockages. At the same time, the sink outlet is opened to a 160-millimeter pipe eye, which facilitates the direct discharge of wastewater from the sink into the tank, improving drainage efficiency and avoiding the accumulation or backflow of wastewater in the pipes.
In conclusion, the size of the sewage outlet for mobile toilets needs to be comprehensively determined based on factors such as the type of mobile toilet, the number of users, facility configuration, and whether it is connected to a septic tank to ensure its normal and efficient operation.
