A useful utility review starts with actual meters, bills, wash counts and service terms for the site. A general gallons-per-car range cannot establish the operating cost or savings available at a particular New York car wash.
Identify the services and meter boundaries
List each water, sewer, electricity and fuel account, its service address, meter, unit and billing period. Identify shared meters, non-wash tenants, irrigation, restrooms, leaks, seasonal equipment and estimated readings. Confirm which party pays under the lease and whether billed amounts include reimbursements or charges for another use.
Fresh water entering the property and water circulated within a reclaim system are different populations. Adding recirculated water to metered fresh water can overstate purchased use. Conversely, a low fresh-water reading does not prove acceptable treatment, discharge or equipment condition. Keep environmental approvals and actual wastewater destination in their own review.
Read the tariff components separately
| Bill component | Review question | Evidence |
|---|---|---|
| Fixed service charge | Does it continue when wash activity falls? | Applicable tariff, meter size and service class |
| Water volume | Are readings, multipliers and units correct? | Opening/closing reads and billed consumption |
| Sewer charge | What volume or approved allowance is used? | Actual sewer rule and account-specific adjustment |
| Electricity energy/demand | Are kWh and kW charges being confused? | Rate schedule and interval/demand records |
| Fuel and seasonal equipment | What process or heating load explains variation? | Deliveries, bills, hours and operating observations |
| Corrections and arrears | Is this recurring use or a prior-period settlement? | Credit, estimate correction or payment agreement |
A single blended dollar-per-wash ratio mixes fixed and variable charges. It can describe a complete matched period, but it should not automatically become the marginal cost of another wash. Peak demand or a tariff step can also make the next unit different from the average. Read the applicable utility’s current tariff and account classification; another location’s rate does not determine this site’s bill.
Use the existing meter and bill workbook
The utility reconciliation tool converts supported meter units and compares entered bill components with the actual bill. Keep billed water and sewer quantities distinct when their rules differ. Its simple rate inputs do not reproduce every tier, demand ratchet, tax, minimum or utility-specific adjustment; enter supported adjustments with the relevant scope.
In its fictional case, a 12,000-cubic-foot meter difference corresponds to 120 hundred-cubic-feet. After a separately documented 6,000 gallons of non-wash use, the result can be divided by 3,000 matched washes. Separately, 120 billed water units at $5, 100 sewer units at $8, a $50 fixed charge and a −$20 adjustment total $1,430. An actual bill of $1,438 leaves an $8 charge difference to investigate. The entered rates and quantities are teaching assumptions, not New York utility prices.
Match operating evidence to the billing window
Use the exact meter-reading dates rather than the invoice month label alone. Obtain daily activity where billing periods cross months. Explain rewash, member and premium-application counts rather than assuming every counter measures the same service. Record outages, maintenance, fresh-water bypass and reclaim availability. Avoid attributing the entire difference between months to weather when hours, mix or equipment also changed.
The EPA’s November 2023 vehicle-wash guidance discusses wash configurations and water reclamation. It is useful technical context, but its examples and historical observations do not establish this site’s use or guaranteed savings. Obtain a scoped inspection and evidence appropriate to the installed system.
Evaluate an efficiency project as a separate case
A proposal should state the measured baseline, equipment configuration, operating assumptions, installation cost, maintenance effects, closure period and measurement plan. Separate reduced purchased volume from reduced bill cost: fixed charges and tariff provisions may remain. Compare the project against continued operation using the incremental project cash tool, with the actual project scope, rather than applying an unsupported gallons-saved range.
Link water evidence to the equipment condition register and chemical inventory review while keeping their units separate. For a buyer, also confirm account setup, deposits, continuity responsibilities and closing meter reads in the operating handoff.
Keep an exception register
Assign each unexplained quantity or charge a source, owner and next action. An estimated bill, unknown multiplier or shared meter needs evidence before it becomes a normalized expense. Preserve useful existing bills and meter logs, document a known zero explicitly, and leave an unavailable measure unknown. The next decision should rest on the reconciled site record rather than a format-wide cost claim.
