Water Usage Assessment
for Car Wash Operations

We'll walk through your tunnel from entrance to exit — following the actual flow of a car through your wash, from the first pre-soak all the way to spot-free rinse and dryers.

Your water treatment system

What equipment do you have on-site? This determines which water sources are available for each stage.

Reclaim System
RO (Spot-Free) System
RO Reject Water (ROR)
RO reject is the higher-mineral byproduct of your RO system — the water that doesn't pass through the membrane. Many operators route this into high-pressure applications rather than sending it to drain.
Water Softener
Overall Fresh Water Use
💡Fresh (municipal) water is what you pay your utility for. Reclaim and RO reject come from fresh water but don't add to your purchased volume.

Build Your Wash Tunnel

Lay out every stage in the exact order cars pass through your tunnel, from entrance to exit. We've pre-loaded a typical lineup below — reorder, rename, skip, or add stages until it matches your tunnel exactly.

💡Click ✓ We Have It to expand a stage and set its water source and gallons per car. Use the ▲▼ arrows to move a stage earlier or later in the tunnel, and rename any stage to match what you call it in-house — that name (and its gallons per car) will carry straight through to your report.

Utility rates

Just two numbers — fresh water and sewer. Find them on your monthly water bill.

Water & Sewer Costs
💡Look for "per CCF", "per 1,000 gallons", or "per gallon" on your bill. To convert: 1 CCF = 748 gallons (divide per-CCF rate by 748), or divide per-1,000-gal rate by 1,000.
