The Australian case

Why water recycling pays off for Australian laundries

Australian commercial water is among the more expensive in the world, and a metered laundry pays twice on every litre — once as supply, once as sewer and trade-waste discharge. That makes on-site recycling a direct operating saving, not just a sustainability measure.

$3.12 → $3.78/kL

Rising water charges

Sydney Water's non-residential usage charge rises from $3.12 to $3.78 per kL under IPART's 2025–30 determination, with a drought rate of $3.61/kL if dam levels fall below 60% — and sewer plus trade-waste charges sit on top. Recycling 45–65% cuts both sides.

Trade-waste agreements

Laundry wastewater is classed as trade waste — in NSW you must hold a Sydney Water agreement before discharging, and large laundries (over 10 tonnes/week) often need pH correction and temperature reduction first. Recycling reduces the volume and strength you discharge, easing those requirements.

Drought resilience

Australian cities face recurring drought and water restrictions on commercial users, and Sydney's pricing builds in a drought surcharge. Cutting mains demand by 45–65% keeps you operating through restrictions and reduces exposure to drought pricing.

Figures reflect Sydney Water's IPART-approved 2025–30 prices; water and trade-waste charges vary by state utility across Australia. We confirm your local rates as part of the audit.

Australian commercial laundry water recycling explained

Key facts at a glance

This page explains how Wientjens Blue Ocean systems recycle water in Australian commercial laundries by collecting suitable wastewater, filtering it, recovering heat and returning clean warm water to selected wash stages.

The process is built for high-volume hotels, hospitals, aged care laundries, textile rental plants and industrial laundries that want water reuse without replacing existing washing machines.

  • Service area: Australia, with AUD ROI modelling and Australian commercial laundry use cases.
  • Core process: collection, disc filtration, heat recovery, clean water return and Cloud 4.0 monitoring.
  • Typical results: 45-65% water savings and around 15% gas reduction, depending on site conditions.
  • Retrofit fit: designed to integrate with existing tunnel washers, washer extractors and major commercial washer brands.

How It Works

5-Step Process Flow

Spent wash water becomes reusable supply, end to end — automatic, and with no trade-off in wash quality.

01

Wash Water

Diverted as it drains from the tunnel washer or extractors

02

Disc Filtration

Discs strip out particles and contaminants down to 25 microns

03

Heat Recovery

Residual warmth is reclaimed to pre-heat incoming mains

04

Clean Water Return

Pre-warmed water is fed back into the wash cycle

05

Cloud Monitoring

Output is tracked remotely with maintenance flagged ahead of time

Compatibility

Works With Your Existing Equipment

A retrofit, not a rip-and-replace — it ties into whatever washers your Australian laundry already runs.

Compatible Brands

Alliance Milnor Kannegiesser Girbau Jensen Lavatec + all others

Integration Points

Supply Side

Recovered water joins the wash supply lines, with mains topping up automatically whenever it is needed.

Drain Side

Your current drains are re-routed into the collection tank — no structural changes to the washers.

Zero Downtime Risk

Take the unit offline for servicing and the washers simply revert to 100% mains water on their own. The laundry keeps running and production never pauses.

Frequently Asked Questions

Common questions about how water recycling works

How long does the recycling process take?

It runs continuously rather than in batches, so treated water is always sitting ready in the buffer tanks. Your washers draw on it instantly and never sit idle waiting for supply.

Will recycled water affect linen quality or whiteness?

No. Whites and colours are kept on separate streams, and the recovered water comes back clear, colourless and odour-free. Australian hotels and healthcare laundries running the system tell us their linen looks the same or better than before.

Can all the filtered water be reused, or just some of it?

Filtration recovers roughly 45-65% of your throughput, and in practice almost all of that recovered volume goes straight back into the wash — very little is sent on to the sewer.

What happens if the recycling system breaks down?

Failover is built in. The moment a fault is detected the washers fall back to 100% fresh water, so the laundry carries on uninterrupted. Uptime sits at 99.2%, and the remote monitoring usually spots a developing problem before it ever becomes downtime.

How much space does a water recycling system need?

Plan for around 2-5m² of floor area. It can sit inside the plant room or outdoors in a weatherproof enclosure, and the layout is worked around whatever space you have during the free site assessment.

How does the Wientjens Blue Ocean system compare to other water recycling technologies?

Rather than bolting separate recycling, heat-recovery and energy-recapture products together, Blue Ocean delivers all three from one integrated unit. The disc-filtration approach is what gets it to 45-65% water savings while holding 99.2% uptime.
