Vacuum Toilet System
Flush toilets that use suction instead of a gravity cistern — removing waste with a minimal 0.5 to 1.5 litres of water, in Indian and European style models.
Made in India · UTC Original Design
Suction, not gravity.
Vacuum toilets are flush toilets that use suction for the removal of faeces and urine, resulting in a minimal requirement of water — 0.5 to 1.5 litres per flush.
Vacuum toilets provide the same level of comfort as traditional flush toilets and help save costs through the minimised amount of flush water.
Because the effluent has a high organic-matter content, vacuum toilets are specifically suited for use with separate greywater and blackwater treatment, or with anaerobic digestion for biogas production.
Designed in-house, down to the valve.
Every unit carries UTC's original design — a stainless bowl, pneumatic flush valve and electronic control packed into one compact assembly.
The vacuum flush in action
Built for every mode of transport.
A hygienic vacuum toilet in Indian and European style models — collecting waste in its own storage, cleaning itself with economical water, and running on a combined vacuum and pressure system suited to the rail, air, maritime and road sectors.
From 10 litres to 0.5 litres per use
Average water consumption for a single use in a conventional system is around 10 litres. In the system UTC has created, it falls to 0.5 litres — including cleaning of the bowl.
Runs on what every vehicle already has
The system needs only compressed air, 24V DC energy and water — all present in transportation vehicles — and combines pneumatic and electronic systems in one unit.

Stainless steel, inside and out
For hygiene reasons, all metal equipment used in the system is manufactured from AISI 304 or 316 quality stainless steel.
Major Advantages of the UTC Vacuum Toilet

Benefits & what to plan for.
An honest view of vacuum sanitation — the advantages it brings, and the points to plan for at installation.
Advantages of Vacuum Toilets
- Large water savings
- No deposits in the toilet, reduced use of detergents
- Very hygienic
- Flexible and convenient
- No deposits in the pipes
- Odour-free
- Facilitates reuse of urine and faeces
- Applicable in many different constructions
Planning Considerations
- Relatively high investment cost
- Depends on electric power supply
- Coarse materials can lead to blockage of the collection system
- House service connection and vacuum station have to be maintained
- Needs a vacuum station (house- or community-based)
- Requires space for connection
- Bulky material (e.g. sanitary napkins) can lead to clogging
Vacuum toilets on the move.
The same vacuum-flush system built into a bus — a self-contained toilet cabin with its own fresh-water and waste tanks, running the same low-water flush on the move.
