20 kg2000 kg

A hotel of around 50 rooms at 65% occupancy processes close to 150 kg a day, the assumption used in the article.

Reference bands: 17 to 22 industrial washer with no conservation measures, 12 to 15 with rinse water reuse, 7.5 to 12 continuous tunnel, 1.5 to 4.5 tunnel with recycling.

Use the rate on your own bill, water plus sewerage.

Pick 300 or 330 if the property closes out of season.

Result

What your laundry uses

An estimate of water and cost, from the values you chose and the reference bands for the sector.

The 35% applies mostly to operations with no conservation measures in place. If you are already below roughly 12 to 15 L/kg the real gain will be smaller, and the scenario beside this one becomes illustrative only.

Your operation já está no nível de referência. Aos 13 L/kg ou abaixo, não há redução de água que se possa estimar aqui — a partir daí o que sobra depende do equipamento, dos programas e da carga, e só se sabe medindo. Preferimos dizer isto a mostrar-lhe uma poupança que não podemos justificar.

35% means going from around 20 L/kg to around 13 L/kg, through rinse water reuse and disciplined loading. These are the article’s reference figures, not Arelia measurements.

How we work it out.

The simulation rests on public reference figures for the sector, not on Arelia measurements. Here are the assumptions, so you can judge them.

The right metric
L/kg
Litres of water per kilo of linen processed. Measuring in m³ per month compares nothing: volume rises in August and falls in February for reasons that have nothing to do with efficiency.
Where the water goes
90 to 92%
The share of consumption that sits in the wash process itself. Steam generation accounts for 5 to 8% and ancillary uses for 2 to 3%. Measures outside the machine move 10% of the total at most.
Where the 35% comes from
20 → 13 L/kg
It is the midpoint of the first two rows of the table below. An operation with no conservation measures that starts reusing the final rinse water cuts exactly that much. Anyone already below 15 L/kg has considerably less room.
Cost of water
Your own rate
The euro per cubic metre comes entirely from the value you chose, water plus sewerage. We assume no average rate, because they vary widely between Algarve municipalities.
Sources
Public
L/kg bands and the breakdown of consumption come from public reference figures for commercial laundries. None of these numbers is an Arelia measurement. Read the full article, with the sources.
What this is not
An estimate
A starting point for a conversation, not a quote. Real consumption depends on the equipment, the programmes, the loading and the local rate, and the only way to know it is to measure it.

Reference bands.

Use them to place your own operation in the "litres per kilo, today" field.

Notice This tool gives indicative estimates based on the assumptions you choose and on reference figures for the sector. It is not a commercial offer and commits Arelia to nothing. Real consumption depends on the equipment, the programmes, the loading and the local rate.
