Liquid Waste Vacuum Truck

Purpose-built vacuum trucks designed to handle liquid waste, sludge and mud with maximum uptime, simple operation and proven reliability in Australian conditions.

The VTS MudVac, LiquidVac and LiteVac range of liquid vacuum trucks are purpose-built for Australian conditions, delivering tough, reliable performance without unnecessary complexity and no computer systems. The MudVac is designed to handle liquid, sludge and mud waste for heavier and more abrasive applications, while the LiquidVac focuses on bulk liquid waste collection where capacity, airflow and uptime matter most. The LiteVac is a lightweight aluminium liquid waste truck, best suited to septic and grease work where efficiency and payload are key. All three liquid vacuum trucks are engineered for practical, operator-friendly use, straightforward maintenance and long-term ownership backed by the VTS team.

What is a LiquidVac?

A LiquidVac is a purpose-built liquid vacuum truck designed for bulk liquid waste collection and transport. It delivers strong, quiet vacuum performance with simple systems that suit high-volume, day-to-day pumping work.

In plain terms, it:

  • Uses a liquid ring vacuum system to efficiently collect liquid waste
  • Handles stubborn liquid wastes with high tolerance to carryover
  • Stores waste safely in a sealed tank for transport and controlled discharge
  • Operates using straightforward hydraulic systems with no computer controls

Rather than complex electronics, the LiquidVac focuses on durability, ease of use and fast turnaround on site.

In short, the LiquidVac is a reliable liquid waste truck for bulk liquid work where uptime and consistency matter.

What is a LiteVac?

A LiteVac is a lightweight liquid vacuum truck designed specifically for septic and grease waste applications. Using an aluminium tank to reduce weight, it maximises payload while remaining easy to operate and economical to run.

In plain terms, it:

  • Collects septic and grease waste using a powerful, quiet vacuum system
  • Uses an aluminium tank to improve payload and fuel efficiency
  • Operates with simple hydraulic controls that are easy to learn
  • Avoids complex electronics to keep maintenance simple and reliable

The LiteVac is best suited to operators focused on septic pumping, grease trap servicing and routine liquid waste work.

In short, the LiteVac is the best liquid waste truck for septic and grease where simplicity and efficiency are key.

What is a MudVac?

A MudVac is a heavy-duty liquid vacuum truck designed to handle liquid, sludge and mud waste. It is built for tougher applications where thicker and more abrasive materials are part of the job.

In plain terms, it:

  • Uses a liquid ring vacuum system with high tolerance to carryover
  • Handles thick slurries, drilling mud and challenging waste materials
  • Moves waste efficiently using high-flow plumbing and robust hydraulics
  • Runs on simple hydraulic controls with no unnecessary electronics

Where lighter liquid waste trucks are not suitable, the MudVac is built to keep working.

In short, the MudVac is the liquid waste truck for heavy and abrasive waste in demanding conditions.

Frequently asked questions

What are the different types of liquid vacuum trucks?

Liquid vacuum trucks are typically configured to suit different waste types:

  • LiquidVac for bulk liquid waste
  • LiteVac for septic and grease waste where payload and efficiency matter
  • MudVac for heavier sludge, slurry and mud applications

Choosing the right one depends on what you pump most often.

Common uses include:

  • Septic tank pump-outs
  • Grease trap servicing
  • Liquid waste collection and transport
  • Sludge and slurry removal
  • Industrial and commercial liquid waste

Safety features vary by configuration but typically include sealed vacuum tanks, pressure and vacuum relief valves, shut-off systems, and controlled discharge points. Safe operation also depends on correct procedures and operator training.

Both airflow and vacuum matter:

  • Airflow helps move liquid quickly
  • Vacuum helps lift heavier or thicker waste

A well-matched system gives faster loading and better control, not just a bigger number on paper.

Liquid vacuum trucks are used across:

  • Local government and councils
  • Septic and wastewater services
  • Food and hospitality sites for grease traps
  • Industrial and commercial facilities
  • Agricultural and rural operations

Routine maintenance includes checking filters, seals, valves, hoses and hydraulic components. VTS trucks are designed with simple layouts and accessible service points to keep maintenance fast and straightforward.

Requirements vary depending on waste type and location. Operators must follow local council rules, EPA guidelines and disposal regulations. Always ensure waste is transported and disposed of at approved facilities.

Liquid vacuum trucks are available in a range of sizes, commonly from around 7,000 litres through to 12,500 litres. Capacity selection depends on payload limits, waste type and daily workload.

VTS liquid vacuum trucks use straightforward hydraulic and mechanical controls with no computer systems. This makes them easy to learn, easy to operate and easy to maintain.

It comes down to what you pump most often, how heavy the material is and how much capacity you need. Tell us about your work and we will recommend the right configuration for your crew and workload.

Yes. Liquid sucker truck is a common industry term for a liquid vacuum truck. Both describe trucks that use vacuum suction to collect and transport liquid waste. You might also hear them called liquid waste trucks or vacuum tankers, depending on the job and the operator.
