Mobile Toilet Water Supply and Drainage

The water supply and drainage system of mobile toilets is scientifically designed to meet sanitary needs in various scenarios, with diverse and distinctive water supply and drainage methods.

Water Supply System

Mobile toilets are typically equipped with built-in water tanks connected to the bottom via pipes. Water is introduced into facilities such as sinks and toilets through faucets and other devices, supporting cleaning tasks like hand washing and toilet flushing. Some mobile toilets can also be connected to external water sources. When the built-in water tank is low on water or when there are many users with high water demand, connecting to an external water source ensures a continuous and stable water supply to meet larger-scale water needs.

Drainage System

• Flush and Non-flush Suction Types: Flush-type mobile toilets have a sewage tank at the bottom to collect flushed sewage; non-flush types directly receive waste in the sewage tank. Due to the limited capacity of the sewage tank, regular suction is required to prevent overflow and transfer the sewage to an appropriate treatment site.
• Recirculating Flush Type: This type uses biofilm technology to treat fecal sewage. After filtration and other processes, the treated water is recycled for flushing fixtures. This method not only effectively reduces the frequency of sewage suction, lowering operational costs, but also significantly conserves water resources, aligning with sustainable development principles.
• Dry Packing Type: Degradable plastic bags are used to receive waste, with a new bag automatically replaced after each use. This design requires no water flushing, making waste collection convenient, and the degradable plastic bags are environmentally friendly, reducing the complexity and difficulty of sewage treatment.
• Conventional Flush Type: It can be connected to water supply and drainage pipes, with manual or automatic sensing for waste discharge, directly emptying sewage into septic tanks or municipal sewer networks. This drainage method is suitable for environments with water supply and has relatively low construction costs, being widely used in areas with well-developed municipal sewer networks and water supply conditions.
• Vacuum Sewage System: Utilizing negative pressure principles, a vacuum pump rapidly sucks sewage into a collection container. It is efficient, uses less water, and effectively prevents sewage leakage and odor diffusion, providing a cleaner and more comfortable environment for users.
• Water Storage Sewage System: Waste is flushed into a storage tank through water flushing. When the storage tank is full, it needs to be cleaned and replaced. This system is suitable for locations with sufficient water supply and easy cleaning, ensuring the normal operation of mobile toilets.

In addition, some mobile toilets also employ biodegradation technology to convert organic matter in sewage into harmless substances before discharge, further reducing environmental pollution.
