How Much Water Does an Industrial Pressure Washer Use? A Guide to Reducing Water and Cleaning Costs
Water consumption is an increasingly important consideration for businesses operating industrial pressure washing equipment.
Whether you're washing commercial vehicles, plant machinery, equipment or working areas, every litre of water has a cost. And when cleaning takes place several times a day, across multiple vehicles or throughout a large site, seemingly small inefficiencies can quickly add up.
So, how much water does an industrial pressure washer actually use?
The simple answer is that it depends on the machine. Industrial systems vary significantly in flow rate, pressure and specification, while the amount of water consumed during each cleaning task also depends on how long the pressure washer needs to run.
In this guide, we'll explain how industrial pressure washer water usage is calculated, what affects it and the practical steps businesses can take to reduce both water consumption and overall cleaning costs.
How Much Water Does an Industrial Pressure Washer Use?
Industrial pressure washer water usage is usually expressed as a flow rate in litres per minute (LPM). For example, the Rhinowash RX Series starts from a flow rate of 13 litres per minute, with systems specified according to the requirements of the individual operation.
That means a pressure washer operating continuously at 13 LPM would theoretically use:
130 litres in 10 minutes
390 litres in 30 minutes
780 litres in one hour
However, LPM only tells part of the story. The more useful figure for a business is how much water it takes to complete each clean.
Why Flow Rate Matters
Flow rate is the amount of water the pressure washer delivers. In industrial cleaning, that water helps carry loosened dirt and contamination away from the surface.
A lower flow rate doesn’t automatically mean greater efficiency. If it makes the job take longer, you could end up using more water overall.
What Determines Industrial Pressure Washer Water Usage?:
Flow Rate - the higher the LPM, the more water the system can deliver. However, this should always be considered alongside cleaning time, as a higher-flow system may complete the job much faster.
Cleaning Time - the longer the trigger is active, the more water you use. Reducing each clean by even a few minutes can create significant savings across a busy operation.
Type of Contamination - light dirt requires less effort than thick mud, grease or oil. Tougher contamination can increase cleaning time and water consumption if the system isn’t properly suited to the job.
Hot vs Cold Water - cold water is suitable for many everyday cleaning tasks, while hot water can be more effective against grease, oil and stubborn contamination. Using the right option can make cleaning faster and more efficient.
Operator Technique - how the equipment is used matters too. Working systematically, using the right accessories and avoiding unnecessary trigger time can reduce water consumption without compromising the result.
How to Reduce Industrial Pressure Washer Water Usage:
Choose the Right System - choose a system around what you're actually cleaning, how often it's used and the contamination involved. The right specification can complete the job effectively without unnecessary water use.
Reduce Cleaning Time - look for areas where operators are spending longer than necessary. Reducing repeat passes and improving the cleaning process can save both water and labour.
Optimise the Wash Bay - good equipment can still be held back by a poor setup. Convenient hose positioning, easy access and an efficient layout can make every clean quicker and simpler.
Use Hot Water Where it Adds Value - hot water isn't needed for every job, but it can make a significant difference when tackling oil, grease and stubborn contamination. The key is using it where it genuinely improves efficiency.
Maintain Your Equipment - leaks, worn nozzles and blocked filters can reduce performance and waste water. Regular maintenance helps keep the system operating as it should.
Train Operators - small changes in technique can make a big difference. Training operators to work systematically and avoid unnecessary trigger time helps reduce waste while maintaining cleaning standards.
How Rhinowash Helps Businesses Improve Cleaning Efficiency
Systems Specified Around the Application
Rhinowash looks at the job first, not simply the machine specification. Understanding what needs cleaned, how often and in what conditions helps us recommend the right balance of pressure, flow and temperature.
Hot and Cold Water Options
Different contaminants require different approaches. Rhinowash offers hot and cold water systems, allowing businesses to choose the option that best suits their cleaning requirements rather than paying for performance they don't need.
Static Systems Designed Around Efficient Working
A well-positioned static system removes the need to repeatedly move and set up equipment. This can create a faster, more consistent cleaning process for busy sites.
Reliability That Protects Efficiency
Efficiency quickly disappears when equipment breaks down. Rhinowash systems are designed for demanding environments, with service support and Quick Swap modular technology helping minimise disruption.
More Than Just the Machine
Reducing water consumption isn't about finding the lowest LPM figure. Rhinowash considers the wider cleaning process to help businesses improve water use, cleaning time and overall operating efficiency.
Final Thoughts
So, how much water does an industrial pressure washer use?
The litres-per-minute figure gives you a starting point, but it doesn't tell you whether your cleaning process is efficient.
What matters is how much water, time and energy you use to achieve the required result.
At Rhinowash, we've spent more than 50 years developing industrial pressure washing solutions around the realities of how businesses operate.
