Aged Care Laundry Water Recycling Australia

Water recycling can cut your laundry’s water use by 45–65% and gas use by around 15%. For laundries processing 100 tonnes/week, payback can be as fast as 6 months. Use measured laundry water use, relevant gas use, eligible reuse streams and actual utility charges to assess the benefit. Include additional operating, testing and maintenance costs before calculating net annual savings. Bed count alone does not establish throughput or payback.

Equipment selection does not establish conformance with the strengthened Aged Care Quality Standards or approve a laundry process. The strengthened framework applied from 1 November 2025; Standard 4 covers the environment and infection prevention and control. Review AS 4146:2024, which superseded AS/NZS 4146:2000 in Australia, together with applicable contracts, facility policies and jurisdictional requirements. The care provider’s responsible laundry, infection-control and engineering teams should approve the proposed process and acceptance evidence.

Identify where washing occurs, who owns the equipment and who pays the utilities. For outsourced linen, involve the laundry operator and review the service contract before assigning any saving to the facility. For a central laundry, collect its total kilograms processed and separate each site’s linen-service costs from the plant’s water and gas costs. A plant saving does not automatically change an individual facility’s utility bill or contract price.

Assess streams individually. Map resident bedding, towels, personal clothing, staff uniforms and dining linen with their soiling, chemicals and wash recipes. The responsible teams should define accepted collection and reuse points, excluded water and separation requirements. Give linen subject to additional infection precautions, outbreak procedures or chemical contamination an explicit assessment. Filtration specifications alone do not validate disinfection or approve reuse for every item.

Agree representative trials with the laundry operator, chemical supplier, linen supplier and care team as relevant. Include the fabrics, colours, soiling and wash recipes actually used. Set acceptance criteria for cleanliness, appearance, odour and fabric feel alongside the required hygiene evidence. Retain personal-clothing identification and return arrangements. Confirm accepted streams and settings before routine reuse.

Use the facility’s infection-control and outbreak procedures to decide whether reuse must change or stop. Agree isolation, fresh-water capacity, alarm escalation and restart criteria for the selected design. Plan reserve linen or an alternative laundry service where needed, and test the contingency during commissioning. Confirm service coverage and response arrangements in writing; automatic control does not guarantee continuous linen supply.

Start with actual linen kilograms, water and gas records, the approved reuse scope and current account charges. Calculate avoided variable costs less additional electricity, servicing, consumables, testing and staff tasks. Simple payback in years is the installed quotation divided by positive net annual savings, using a consistent GST basis. Payback can be as fast as 6 months at 100 tonnes/week. Use your own laundry’s workload and costs to calculate its return.

Review responsibilities for new collection lines, storage, controls, alarms, sampling, cleaning and maintenance before commissioning. Have staff demonstrate normal operation, safe isolation, escalation and restart. Agree who records meter readings and quality results, who reviews exceptions and who authorises any expansion of reuse. Keep the facility’s approved wash and disinfection requirements unless the responsible teams approve a change.
