Maintaining sewer networks and drainage systems is one of the biggest challenges faced by municipalities, industrial facilities, housing societies, and infrastructure development projects. Traditional manual methods are slow, unhygienic, and risky for workers. Modern sewer suction machines have revolutionized waste removal with powerful vacuum suction, high-pressure cleaning, and efficient debris extraction.
This buyer’s guide will walk you through the top 7 types of sewer suction machines, their features, applications, and how to select the right machine based on your requirements.
7 Best Sewer Suction Machines In 2026
1. Trailer Mounted Sewer Suction Machine
What It Is
A trailer mounted sewer suction machine is a compact yet powerful unit designed to be towed by a tractor or light vehicle. It is ideal for small to medium-scale suction operations.
Key Features
- Mounted on a robust trailer for easy transport
- A high-capacity vacuum tank (typically 3000–5000 liters)
- Powerful vacuum pump for sludge and waste removal
- Simple control panel for smooth operation
Best For
✔ Small municipalities
✔ Septic tank cleaning
✔ Rural sanitation projects
✔ Housing societies
Why Choose It
Trailer-mounted units are cost-effective, flexible, and easy to maneuver in narrow roads, making them suitable where a full truck-mounted system is not necessary.
2. Sewer Suction Cum Jetting Machine
What It Is
A sewer suction cum jetting machine is a versatile machine that combines high-pressure water jetting with vacuum suction, enabling simultaneous blockage removal and waste extraction.
Key Features
- Dual functionality — jetting + suction
- Two separate tanks — fresh water tank for jetting and sludge tank for suction
- High-pressure pump (capable of 100–300 bar pressure)
- Large vacuum pump for powerful waste removal
Best For
✔ Municipal sewer networks
✔ Industrial drainage systems
✔ Prevention of sewer blockages
✔ Heavy-duty cleaning tasks
Why Choose It
This hybrid machine eliminates the need for separate jetting and suction vehicles, reducing equipment cost while increasing operational efficiency. It’s the most popular choice for municipal corporations and large sanitation projects.
3. Truck Mounted Sewer Suction Machine
What It Is
A truck mounted sewer suction machine is a heavy-duty vacuum unit installed on a commercial truck chassis. It is designed for large-scale operations with high-capacity tanks and robust suction power.
Key Features
- Large capacity tanks (5000–12000 liters or more)
- Heavy-duty vacuum pump systems
- Hydraulic unloading options
- Mounted on reliable truck platforms for mobility
Best For
✔ Large cities and urban sanitation departments
✔ Industrial estates
✔ Continuous operation environments
Why Choose It
Truck mounted systems offer unmatched mobility and capacity for continuous and rigorous suction tasks on highways, urban streets, and industrial locales. Their larger tank means fewer return trips for unloading.
4. Sewer Jetting Machine
What It Is
Sewer jetting machines focus on breaking solid blockages using concentrated high-pressure water streams. Although they are primarily cleaning devices, when paired with a suction system, they support efficient debris removal.
Key Features
- High pressure plunger or triplex pumps
- Pressure ranging from 100–250 bar
- Long hose reels for extended reach
- Specialized nozzles for grease, mud, and debris
Best For
✔ Preventive sewer maintenance
✔ Heavy grease and sludge removal
✔ Industrial pipelines
✔ Stormwater drains
Why Choose It
Jetting machines are essential when blockages are caused by stubborn materials like hardened grease, sand, or mineral deposits. They break the clog, making suction easier and faster.
5. Truck Mounted Sewer Suction Cum Jetting Machine
What It Is
This is the most advanced all-in-one system combining the benefits of high-pressure jetting and powerful suction in one vehicle.
Key Features
- Dual-functionality in one truck
- High pressure up to 300+ bar
- Large sludge tank and fresh water tank
- Advanced control systems for efficient operation
Best For
✔ Municipal corporations with heavy-duty requirements
✔ Smart city sanitation missions
✔ Industrially dense areas
✔ Airports, railway stations, and large campuses
Why Choose It
With combined functions on a single chassis, this machine eliminates the need for separate jetting and suction units, improving efficiency while minimizing maintenance costs. It’s ideal for overhead sewer cleaning and heavy blockage removal.
6. Engine Driven Trailer Mounted Sewer Suction Machine
What It Is
An engine driven trailer mounted sewer suction machine is similar to a standard trailer unit but with its own engine for independent operation. This eliminates the need for a tractor’s PTO (power take-off).
Key Features
- Self-power unit with diesel engine
- Easy to deploy in remote or off-grid areas
- Large vacuum tank and strong suction power
- Suitable for standalone operations
Best For
✔ Contractors and rental businesses
✔ Rural and remote locations
✔ Quick emergency suction needs
Why Choose It
This unit does not rely on another vehicle for power, enabling flexible and independent operation. It’s especially useful for areas where tractor or truck PTO options are unavailable.
7. Truck Mounted Sewer Jetting Machine
What It Is
A truck mounted sewer jetting machine is designed to deliver high-pressure water for deep cleaning of sewer lines. It may be used on its own or alongside suction vehicles depending on operational needs.
Key Features
- Mounted on heavy-duty truck chassis
- High pressure output (100–300 bar)
- Large water tank
- Long hose reel for extended reach
Best For
✔ Long sewer runs
✔ Large stormwater drains
✔ High-flow industrial pipelines
✔ Frequent and preventive maintenance
Why Choose It
This machine focuses on power and reach, making it suited for large-scale jetting operations where blockages are frequent and tough.
How to Choose the Right Sewer Suction Machine
When selecting a suction machine, consider these factors:
1. Operational Needs
- Small villages or housing societies: Trailer mounted suction machines
- Municipal networks: Suction cum jetting trucks
- Industrial pipelines: High pressure jetting machines
2. Tank Capacity
- Up to 5000 L: Small to mid-sized operations
- 5000–10000 L: Medium urban or township requirements
- Above 10000 L: Large cities, industrial complexes
3. Power Source
- Tractor PTO powered: Suitable for trailer-based equipment
- Engine driven: Independent units with flexibility
- Truck mounted: Best for continuous heavy-duty work
4. Pressure & Performance
Higher pressure is essential for stubborn blockages. Machines with 150 bar and above are generally suitable for most municipal and industrial settings.
5. Build Quality & Safety
Ensure:
- Corrosion-resistant tanks
- High quality vacuum pumps
- Safety valves and emergency shut-offs
- Easy maintenance access
