The Singapore case
The Savings Case for Singapore Laundries
Water recycling helps your Singapore laundry use less fresh water and reuse warm wash water. Build the business case using actual PUB water charges, gas use, installed cost and running costs. The savings and payback guide explains the figures needed for your site.
Non-domestic potable water, before GST
PUB’s rate from 1 April 2025 combines a S$1.43 tariff, S$0.72 Water Conservation Tax and S$1.09 Waterborne Tax per cubic metre. Use your actual water bill and estimate the volume your laundry can reuse.
PUB Water Efficiency Fund
PUB assesses recycling support using the lower of its water-saving incentive or up to 50% of capital costs, capped at S$5 million. Confirm eligibility and obtain PUB’s approval before the project starts. Regulatory-compliance initiatives are not funded.
Large-user water-efficiency requirements
PUB’s mandatory water-efficiency requirements apply to qualifying large users with net water consumption of at least 60,000 m³ in the previous year. These include notifications, metering of key uses, a Water Efficiency Manager and annual Water Efficiency Management Plans for at least three consecutive years. Check the requirements for your site.
Water prices shown apply from 1 April 2025 and exclude GST. PUB determines funding eligibility and project conditions; confirm the terms before including a grant in your budget.
For your project, review the Singapore PUB approval guide and the installation guide.

Suitability Guide
What Water Can Be Recycled?
The eligible collection and reuse stages depend on your linen mix, wash programme and water-quality requirements.
Loads to Assess for Reuse
Streams for Separate Review
Note: Filtration removes suspended solids; it does not replace the hygiene controls required for your laundry. Agree reuse stages, disinfection and linen-quality checks with the responsible team.
Frequently Asked Questions
Common questions about how water recycling works
How long does the recycling process take?
Blue Ocean filters process water as part of the laundry’s operating cycle, and buffers help match supply with washer demand. Actual flow and tank requirements depend on the selected model, wash programme and production peaks. The provider checks those details against your equipment during the assessment.
Will recycled water affect linen quality or whiteness?
The aim is to maintain your required linen quality while reusing suitable wash water. Agree eligible loads and wash stages with your laundry team, then check linen appearance, feel, odour and the required hygiene evidence before everyday use. Hospital laundries should involve their infection-control team.
Can all the filtered water be reused, or just some of it?
Reuse volume depends on the water you collect, filtration-cleaning requirements and which wash stages can accept the filtrate. Blue Ocean returns filtered process water to the stages agreed for your laundry; it does not mean every litre can replace fresh water. 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.
What happens if the recycling system breaks down?
Agree a fallback plan with the provider, including the available fresh-water supply, system isolation, staff instructions and service support. Wientjens Cloud Dashboards can provide machine-performance data, alerts and maintenance reminders; confirm which features and remote access are included in your quote. Check how your laundry will operate during servicing before the project starts.
How much space does a water recycling system need?
Wientjens lists 4 m² on the Blue Ocean product page and 1.2 m² for AquaMiser. These are equipment figures; your installation also needs space for any additional tanks, connections and maintenance access. The assessment checks the chosen layout against your plant room and site conditions.
How does the Wientjens Blue Ocean system compare to other water recycling technologies?
Blue Ocean combines automatic process-water filtration with insulated buffering so filtered water and its warmth can be reused in the laundry. Compare the selected model’s flow, buffering, cleaning requirements and connections with alternatives using the same wash demand and quality requirements.
