50-liter Water Tank Mobile Toilet

Admin October 11, 2026

The 50-liter water tank is primarily used in mobile toilets for flushing toilets, washing hands, and other scenarios. Its applications include automatic flush tanks for sanitation public toilets, hand-washing tanks for plastic flush mobile toilets, tipping-bucket flush tanks, and high-level tank accessories, with specific technical parameters varying by model and scenario.

1. Automatic Flush Tanks for Sanitation Public Toilets
The 50-liter water tank is commonly used in the automatic flushing systems of sanitation public toilets, such as the trench-type human body induction-controlled flush tank, model cy-n35-2. This tank has a capacity of 50 liters and features an unattended odor control function, triggering flushing through human body induction with a sensing distance of 8-10 meters and requiring an installation height of over 2.5 meters. Its core advantage lies in adjustable flushing parameters: it supports flushing after 1-99 people use it or setting a timed flush for 1-99 minutes, making it suitable for public places with high foot traffic, such as scenic spots and stations.

2. Hand-washing Tanks for Plastic Flush Mobile Toilets
In some plastic flush mobile toilets, the 50-liter water tank is designed as a dedicated hand-washing tank. For example, in one model of mobile toilet, the flushing tank has a capacity of 95 liters, while the hand-washing tank has a capacity of 50 liters, equipped with facilities such as a squat toilet and a hand-washing sink. This design optimizes water resource utilization efficiency by separating flushing and hand-washing water. The fecal storage tank can accommodate up to 350 person-uses and supports storage or direct discharge treatment methods, making it suitable for temporary events and construction sites.

3. Capacity Selection for Tipping-bucket Flush Tanks
Tipping-bucket flush tanks are common flushing devices in mobile toilets, with capacities ranging from 40 liters, 50 liters, 60 liters, to 70 liters. The 50-liter capacity is a medium-sized option suitable for scenarios with limited space but requiring balanced flushing performance. Selection should be based on the model and installation space; for example, some large public restrooms may adopt larger capacities to cope with high-frequency use, while small mobile toilets tend to choose 50 liters to balance performance and cost.

4. Applications of High-level Tank Accessories
Some public toilet high-level tank accessories support a 50-liter capacity, such as hand-pulled public toilet tanks and trench high-level pull-rope flush tanks. These tanks achieve flushing through gravity and are suitable for public scenarios like schools and construction sites. Their advantages include simple structure, low maintenance costs, and the ability of the 50-liter capacity to meet basic flushing needs while avoiding water waste.
