A useful water-use baseline gives a hotel a fair way to see where water goes, when use changes and whether an intervention made a measurable difference. Without a defined boundary, a lower monthly bill may simply reflect lower occupancy or a closed facility. Establish the data before setting targets, then relate it to rooms sold, services and operating hours. For the wider hotel context, see asset optimisation e hotel owners e Feathers Hospitality approach.

These practices work best when information, ownership and verification are part of the routine rather than dependent on one person’s memory. {“A abordagem da Feathers Hospitality” if loc==”pt” else “The Feathers Hospitality approach”} liga orientação e execução.

Key points

  • Record meters, uses, periods and reading sources.
  • Compare use with occupancy and service hours.
  • Verify project effects under comparable conditions.

Which meters and uses belong in the baseline?

List incoming meters, submeters and major uses such as guest rooms, laundry, kitchens, pools, irrigation and staff areas. Record which spaces each meter serves and whether readings are actual or estimated. Where one meter covers several uses, state that limitation instead of assigning a precise share without evidence.

A simple schematic helps the team understand the boundary and identify missing readings. Include meter identifiers, units, reading frequency and a responsible person. The US EPA WaterSense hotel guidance recommends assessing hotel water use and tracking results; its US benchmarks and programmes do not represent Portuguese requirements.

How should use be normalised?

Track total volume alongside an operational denominator such as occupied room-nights, guests or meals served. Choose a denominator that matches the question. Water per available room can make an occupancy decline look like efficiency; water per occupied room may conceal fixed uses such as landscaping or pools.

Keep more than one view if different departments drive demand. Record occupancy and service hours for the same period as meter data. Explain exclusions, such as a leak repair or renovation, so comparisons remain interpretable.

What period is long enough to be useful?

Collect a full operating cycle where possible and preserve daily or weekly readings for diagnosing unusual changes. Monthly utility bills help reconcile totals but can hide short events. Mark meter replacement, estimated bills, weather extremes, maintenance and periods when a facility was closed.

Do not set a target from one quiet month. Compare similar seasons and operating conditions. The TravelBI environmental performance report for Portuguese tourist accommodation offers national context on water practices, not a target for an individual property.

How can the team find unusual consumption?

Create a routine for reading meters and comparing use with a property-specific range. A sudden rise during low occupancy may warrant a check, but it is a signal for investigation rather than proof of a leak. Review irrigation schedules, laundry volumes, pool top-ups and recently completed work.

Give each department a simple way to report a leak or unusual sound, and tell maintenance what information is useful: location, time, visible flow and whether the issue is continuing. Do not ask guests to diagnose plumbing. Escalate suspected damage according to the property’s safety procedure.

How do projects show whether they worked?

Before installing efficient fixtures, changing laundry practice or adjusting irrigation, state the expected mechanism and measurement. Record the date, scope and areas affected. Afterward, compare readings under reasonably similar conditions and check guest experience, maintenance and hygiene implications.

Water-saving measures should not compromise cleaning, sanitation, accessibility or the service standard. Consult qualified professionals on system changes and local rules. A projected saving is not a verified result until the property measures it.

Who owns the data and review?

Assign a person to validate readings, reconcile bills and explain anomalies. Keep source records and a short note of estimates or corrections. Give finance, engineering and operations access to the same agreed figures so that investment decisions are not based on different versions.

Review the baseline when meters, room inventory or operating patterns change. The annual update should record what changed and whether the target still makes sense. Good data supports a practical water plan; it does not by itself prove environmental performance or certification.

Frequently asked questions

Which denominator is best for water use?

It depends on the question. Use per occupied room for stay-related comparisons, or meals served or pool hours for specific uses. Show the total and explain the denominator.

Is one month enough for a baseline?

Usually not if it misses seasonal or occupancy variation. Use a representative period and flag changes, estimates and missing readings.
