How to Reduce Water Usage at Your Laundromat

Water is typically a laundromat's single largest utility expense. Reducing usage doesn't mean compromising wash quality — it means being smarter about how water is used across your operation.

High-Efficiency Machines

The biggest impact comes from your equipment. Modern front-load washers use 30-50% less water than older top-loaders. If you're still running top-loaders, calculate the water cost difference over a year — the savings often justify an equipment upgrade within 3-5 years, and it's the biggest item on our list of energy-efficient upgrades that pay for themselves.

Fix Leaks Immediately

A single dripping hose connection can waste 10+ gallons per day. Walk your facility weekly checking every hose connection, valve, and drain for leaks, and use our guide to spotting and fixing water leaks to trace the ones that aren't obvious. Under-machine puddles are the most obvious sign, but also check the wall connections behind machines where leaks can go unnoticed for months.

Optimize Water Pressure

Excessive water pressure wastes water and wears out fill valves faster, and a leaking or stuck fill valve is one of the common faults covered in our commercial washer troubleshooting guide. Manufacturers publish a wide working range (Dexter rates its washers for 30–120 psi; Alliance's cabinet hardmount installation manual lists 30–85 psi for Speed Queen and Huebsch), but plumbing codes generally require a pressure-reducing valve once static pressure passes 80 psi. If your incoming pressure is above 80 psi, install a pressure regulator. This small investment reduces water waste and extends valve life.

Customer Education

Customers who overload machines often run a second cycle to finish the job — doubling water usage. Clear signage about load sizes helps. Customers who use too much detergent create excessive suds that trigger extra rinse cycles on some machines. Color-coded soap tray labels with fill-line indicators reduce this problem.

Reclaim Systems

Water reclaim systems filter and reuse rinse water for the next wash cycle's initial fill. Vendors claim reductions from roughly a third of total consumption up to 80% for closed-loop systems. Pricing is quoted per installation and scales with machine count, so get a written quote and run the payback against your own metered water and sewer bill before committing. Check local utility rebates — many municipalities incentivize commercial water reclaim.

Track and Measure

Install a sub-meter on your laundromat's water supply if your building has shared utilities. Track monthly consumption against revenue. Gallons per dollar of revenue varies with machine mix and vend prices, so your own month-over-month trend is the useful benchmark. If consumption climbs without a matching rise in revenue, investigate where water is being wasted.
