Construction Drawings for Water-Flush Mobile Toilets

Admin October 19, 2026

Currently, there is no complete set of construction drawing information specifically for water-flush mobile toilets, but construction drawing examples of similar water-flush toilets can be provided for reference. The design of construction drawings for water-flush toilets needs to be customized according to specific usage scenarios, structural types, and functional requirements. The following explains the design key points by combining existing examples:


Construction Drawings for Rural Public Water-Flush Trench Toilets

Two sets of architectural design and construction drawings for water-flush trench toilets released in 2016 are mainly designed for rural public toilet scenarios. The core drawings include the ground floor plan (clarifying the overall layout of the toilet, such as male and female partitions, the location of the management room, and the access point of the septic tank), the roof plan (marking the drainage slope, the structure of the waterproof layer, and the location of the ventilation openings), and the axial elevation (displaying the architectural facade design, the height of doors and windows, and material selection). Such designs usually adopt a brick-concrete structure. The trench-type flushing system realizes fecal flushing through gravity or a small water pump. The septic tank needs to reserve a cleaning opening and comply with environmental protection requirements. The construction drawings will detail the wall thickness (such as 240mm brick walls), ground anti-slip treatment (such as cement polishing or anti-slip floor tiles), and ventilation design (such as natural ventilation windows or mechanical exhaust devices).


Construction Drawings for Modern Public Water-Flush Toilets

Another set of modern public toilet drawings is for a one-story public toilet with a brick-concrete structure, including 24 squatting positions, with complete architectural, structural, water, and electricity professional construction drawings. The key drawings include the first-floor plan (refining the size of each squatting position, partition materials, the location of urinals, and the design of barrier-free passages), the door and window schedule (specifying the types, sizes, and opening methods of doors and windows, such as aluminum alloy sliding windows or security doors), the first-floor water supply and drainage plan (marking the diameter of water supply pipes, drainage slopes, the location of floor drains, and the connection method of the septic tank), and the foundation grounding plan (designing the layout of grounding electrodes according to lightning protection requirements). Such designs emphasize functionality and durability. The partitions for squatting positions usually use stainless steel or compact laminate. The ground drainage slope needs to be ≥2% to prevent water accumulation. Water supply pipes need to use PPR pipes and be equipped with maintenance valves.


Commonalities in the Design of Construction Drawings for Water-Flush Toilets

Whether mobile or fixed, construction drawings for water-flush toilets must meet the following core requirements:

  1. Sanitary standards: The septic tank requires three-stage treatment, and the effluent must comply with the "Hygienic Requirements for the Harmless Treatment of Night Soil" (GB 7959-2012);
  2. Structural safety: Mobile toilets need to consider structural stability during transportation, and fixed toilets need to meet seismic fortification requirements;
  3. Water and electricity support: The water supply system needs to be equipped with a pressure regulating device, the drainage system needs to prevent backflow, and the electrical wiring needs to be waterproof and moisture-proof.

If specific construction drawings for water-flush mobile toilets are required, it is recommended to contact professional environmental protection equipment manufacturers or design institutes to customize the design according to the number of users, usage frequency, and site conditions.
