Trolley Mounted Sewage Evacuation Plant for Railway Bio-Toilet Cleaning
A Trolley Mounted Sewage evacuation plant is a mobile system designed to evacuate, clean and maintain bio-toilet tanks installed in Indian Railways passenger coaches. These plants remove solid and liquid waste from train toilet tanks, separate and recirculate bio-culture (inoculum), and ensure proper functioning of the bio-digester system without manual contact with waste.
Configured as an automatic sewage cleaning machine, the trolley-mounted system operates at railway pit lines, coaching depots and maintenance yards, supporting Indian Railways’ goal of eliminating direct discharge of human waste onto tracks.
What Is a Trolley Mounted Sewage Evacuation Plant?
A Trolley Mounted Sewage evacuation plant is a mobile, self-contained unit mounted on wheels or a trolley frame that can be positioned alongside railway coaches. It uses a heavy-duty pump (typically lobe or progressive cavity pump) to suction waste from bio-toilet tanks through flexible hoses.
As sewage cleaning equipment, the system:
- Evacuates human waste and non-degradable materials (plastic, cloth) from bio-toilet chambers.
- Separates bio-culture (inoculum) and returns it to the tank for continued bacterial action.
- Operates with zero spillage and no direct operator contact with waste, improving safety and hygiene.
This makes it an essential automatic sewage cleaning machine for maintaining Indian Railways’ bio-toilet fleet.
Automatic Sewage Cleaning Machine – How It Works
An automatic sewage cleaning machine for railway bio-toilets operates through the following process:
- Positioning: The trolley-mounted plant is positioned alongside the train coach at the pit line or maintenance yard.
- Connection: Flexible suction hoses are connected to the bio-toilet tank discharge points underneath the coach.
- Evacuation: The heavy-duty lobe pump creates vacuum and suctions waste (human waste, water, bio-culture and non-degradable materials) from the tank into the machine’s collection tank.
- Separation: Internal filters or separators isolate the bio-culture (inoculum) from solid waste and non-degradable materials.
- Recirculation: Clean bio-culture is pumped back into the coach bio-toilet tank to maintain bacterial colony for continued waste digestion.
- Disposal: Collected solid waste is transported to designated treatment facilities for safe disposal.
The entire process is controlled via operator panel, ensuring safe, efficient and hygienic sewage cleaning equipment operation.
Sewage Cleaning Equipment – Key Features
A well-designed sewage cleaning equipment for railway applications includes:
- Heavy-duty lobe pump: Designed to handle thick sludge, solids and fibrous materials without clogging.
- Trolley-mounted mobility: Easy positioning along pit lines and coach maintenance areas without fixed infrastructure.
- Bio-culture separation system: Filters and separators preserve inoculum for return to bio-toilet tanks.
- Zero-spillage design: Sealed tanks and hose connections prevent waste leakage and operator exposure.
- Electric or diesel power: Flexible power options for depot and field operations.
- Control panel: Start/stop, pressure monitoring and safety interlocks for operator safety.
These features make the Trolley Mounted Sewage evacuation plant reliable, hygienic and compliant with Indian Railways maintenance standards.

Sewage Cleaning Machine Price – What Determines Cost
The sewage cleaning machine price depends on several factors:
- Pump capacity and type: Higher-capacity lobe pumps and advanced filtration systems increase cost but improve performance.
- Tank size: Larger collection and separation tanks add cost but reduce disposal trips.
- Power system: Diesel-powered units cost more than electric but offer portability for field operations.
- Automation level: Semi-automatic systems with sensors and timers cost more than manual control units.
- Compliance features: Zero-spillage design, bio-culture separation and Indian Railways certification add to price but are essential for railway applications.

Applications – Where Trolley Mounted Sewage Evacuation Plants Are Used
A Trolley Mounted Sewage evacuation plant is essential in:
- Indian Railways coaching depots: Daily or periodic cleaning of bio-toilet tanks in passenger coaches.
- Railway pit lines and maintenance yards: Evacuation during routine maintenance or when bio-toilets are choked.
- Metro and transit systems: Maintenance of bio-toilet or vacuum toilet systems in metro trains.
- Field operations: Mobile units for coaches stationed away from fixed depot facilities.
By using automatic sewage cleaning machines, Indian Railways improves bio-toilet efficiency, reduces manual labour and maintains hygiene standards across the passenger fleet.
Frequently Asked Questions
What is a Trolley Mounted Sewage evacuation plant used for?
A Trolley Mounted Sewage evacuation plant is used to evacuate waste from bio-toilet tanks in Indian Railways passenger coaches. It removes human waste and non-degradable materials, separates and returns bio-culture (inoculum) to the tank, and ensures proper functioning of the bio-digester system.
How does an automatic sewage cleaning machine work for railway bio-toilets?
An automatic sewage cleaning machine connects flexible hoses to coach bio-toilet tanks, uses a lobe pump to suction waste into the machine, separates bio-culture through filters, returns clean inoculum to the tank, and stores solid waste for safe disposal at treatment facilities.
Can one trolley-mounted plant serve multiple railway coaches?
Yes. A mobile Trolley Mounted Sewage evacuation plant can be moved along pit lines and positioned under multiple coaches sequentially. One unit typically services 10–20 coaches per shift, depending on tank size and waste volume.
How much does a sewage cleaning machine cost for railway applications?
The sewage cleaning machine price for railway bio-toilet evacuation typically ranges from ₹5–12 lakhs depending on pump capacity, tank size, power system (electric or diesel), automation level and compliance features. Contact manufacturers for detailed quotations based on your depot requirements.
