When most people think about pressure washing, they picture the powerful blast that removes years of dirt, moss, and grime. But there's something just as important behind the results you see: Water Flow. At DMS, we sometimes get asked how much water will we use? And more concerning to the customer, Whats the water cost when pressure washing? The answers might surprise you.

pressure washing does use alot of water. But...

Flow Rate vs Pressure - Whats the difference?

Pressure (bar/psi) = the force that lifts dirt etc from the surface

Flow (litres per minute) = the volume of water that washes the dirt away


Think of it like this: pressure loosens the dirt, but without strong flow, the dirt will just sit there. Thats why a professional machine, running at around 21-30 litres per minute, leaves surfaces spotless in a fraction of the time compared to diy machines.


Why Flow Matters For Customers


Cleaner finish - high flow means debris, algae, and moss are completely flushed away.

Less Time On Site - the higher the flow, the quicker the job gets done (less hassle).

Lower Long-Term Costs - because dirt isn't left behind, surfaces stay looking cleaner for longer.


The Real Cost Of Water Use Whilst Pressure Washing


Water use can be a big concern, so let's break it down:


A professional machine like ours runs at 21 litres per minute.

That's 1260 litres per hour (just over 1 cubic metre)

In the West Midlands, the average cost of water is around £2-£3 per cubic metre ( including sewerage charges ).

So even if a driveway clean takes 3hrs, the total water cost is roughly £6-£9.

Most cleans won't take this long, but when you compare that small cost to the transformation of your driveway, or patio, it's clear the value lies in the results, not the water bill.


Efficiency & Responsibility


At DMS, we're mindful of water use. Our machines are designed to clean faster and more efficiently than domestic units, which means less wasted water overall. And because the surface stays cleaner longer, you don't need repeat cleans as often.


Final Word


When it comes to pressure washing, flow is just as important as pressure. It's what delivers that deep, lasting clean without breaking the bank on water bills.
