Construction of Water-Saving Mobile Toilets

The construction methods for water-saving mobile toilets mainly include self-made, pre-fabricated installation, and non-flush/flush solutions, as detailed below:

1. Self-Made Construction Plan

1. Combination of Water Storage Tanks and Pallets Utilize recycled water storage tanks as the main structure, cutting openings for entry and stacking multiple tanks to increase space. Install drainage openings on the interior floor and connect water pipes, along with toilets, faucets, and sinks. Ensure the smoothness of the cut openings to prevent injury to users, and design the drainage system reasonably to prevent backflow of sewage or the spread of odors.

2. Modification of Buckets and Wooden Boards Use a wooden board as the base and install universal wheels for mobility. Fix the cut buckets onto the base, reinforce the bucket bodies with wooden strips, and cut openings for entry. Wrap the wooden boards to prevent scratches. Extend and elevate the structure, then install bucket lids, process wooden doors, and install hinges. Connect elbow drainage pipes at the bottom and add floor drains. Install water pipe connectors on green buckets, assemble showerheads with PVC pipes, connect water pipes, and install valve switches. This plan requires thorough testing of the drainage system's tightness to prevent leaks.

2. Pre-Fabricated Installation Plan

Adopt a modular design that requires no civil engineering work. Fix the structure by assembling columns, with snap-fit connections ensuring a tight fit and simple, efficient installation steps. These toilets are usually equipped with standardized water-saving devices, such as low-flow toilets and sensor faucets, and can be put into use directly. Ensure the selection of pre-fabricated products that comply with national standards, guaranteeing environmentally friendly materials, a sturdy structure, and regular inspection of snap-fit connections for looseness.

3. Non-Flush and Flush Solutions

1. Non-Flush Solution No need to connect to upper and lower water pipes; use biodegradation, packaging, or foam sealing technology to treat excreta. For example, wrap feces with biodegradable film or achieve harmlessness through microbial decomposition. This solution is suitable for water-scarce areas or temporary events but requires regular cleaning of the fecal storage tank and replacement of degradable materials.

2. Flush Water-Saving Solution Requires connection to upper and lower water pipes but reduces water consumption through technologies such as rainwater collection and filtration systems and secondary use of hand-washing water for toilet flushing. For example, filter rainwater and store it in water storage tanks for toilet flushing; filter hand-washing basin drainage and return it to the toilet tank. Ensure the water quality meets toilet flushing standards to prevent pipe blockages or equipment corrosion.

Notes: The self-made plan requires certain hands-on skills, while the pre-fabricated plan requires selection from reputable manufacturers; the non-flush solution requires regular maintenance, and the flush solution requires a stable water source. All plans must comply with local environmental protection and hygiene standards.
