Water Management for
Commercial Laundry Operations.

Commercial laundries — coin-op, on-premise laundry facilities, and industrial laundry processors — have water as their single largest utility cost. Process water consumption, temperature and fill optimisation, and billing classification are rarely audited despite being the most directly controllable cost in the operation.

The Challenge

Commercial laundry water costs are
rarely optimised because no one looks.

Water is the raw material in laundry processing — but most operators treat it as a fixed cost rather than a controllable variable. The result is systematically higher water use than process requirements demand.

Fill levels programmed at manufacturer defaults — not calibrated to actual load profiles

Commercial washing equipment is programmed at manufacturer default fill levels designed for full-load operation. Most commercial laundries run mixed loads — not every cycle is at maximum capacity. Fill levels that don't adjust to actual load weight waste water on every partial load. On a high-volume facility running 300+ cycles per day, the accumulated waste from default fill settings typically amounts to 15–25% of total water consumption.

Discharge tariff classification applied incorrectly — laundry discharge often eligible for industrial rate review

Laundry effluent is classified differently across US municipalities — some apply standard commercial sewer rates, others apply elevated industrial rates based on BOD and TSS load. Facilities classified at industrial rates may be eligible for rate review if their discharge characteristics have improved through detergent changes, water temperature management, or pre-treatment upgrades. WST's discharge classification review identifies reclassification opportunities that laundry operators rarely pursue independently.

Water recycling systems under-utilised or not implemented despite short payback periods

Process water recycling — specifically the reuse of final rinse water as fill water for the next wash cycle — is technically straightforward in most commercial laundry configurations. Payback periods are typically 12–24 months even without any utility incentive. Yet most facilities have never formally quantified the opportunity. WST's water recycling assessment provides the NPV analysis and implementation specification required for a capital committee decision.

WST Approach

How WST approaches
commercial laundry operations.

Process Water Audit — Fill Optimisation & Cycle Analysis

Equipment-level consumption measured against actual load profiles. Optimal fill levels calculated per machine and load type. Controllers reprogrammed to minimum effective fill per cycle. Documented baseline established for before/after comparison.

Discharge Classification Review & Reclassification Filing

Current sewer tariff classification reviewed against municipal industrial pretreatment schedule. Discharge characteristics compared to classification threshold criteria. Reclassification application prepared and filed where a lower rate category is supported by monitoring data.

IoT Process Monitoring — Consumption per Cycle & Leak Detection

Consumption monitoring per machine run cycle identifies equipment performing outside optimal range. Main supply monitoring detects overnight leaks from valve failures and supply line faults. Consumption data formatted for operational reporting and utility dispute support.

Water Recycling ROI Assessment & Capital Case Preparation

Final rinse water reuse and process water recycling opportunities quantified with NPV analysis. Capital specification and equipment recommendations prepared. Utility incentive programmes identified where applicable.

Typical Outcomes

Metric	Outcome
Process water reduction	15–25%
Discharge reclassification saving	$5–20K/yr
Fill optimisation payback	2–4 months
Annual facility saving	$20–60K
Water recycling payback (typical)	12–24 months
Upfront cost	Zero — shared savings
