Reduce Commercial Laundry Water Costs in Singapore

Singapore deliberately prices water to reflect its scarcity, so it is among the most expensive places in the world to run a water-intensive business. From 1 April 2025 the non-domestic potable water tariff is SGD$1.43 per cubic metre (1,000 litres), with NEWater at SGD$1.28 per cubic metre. On top of the tariff, PUB applies a Water Conservation Tax and a Waterborne Fee, and laundries that discharge to the public sewer also pay a trade-effluent charge, so the effective all-in cost per 1,000 litres is meaningfully higher than the tariff alone and depends on your discharge volume and quality. Because a commercial laundry's bill scales directly with the volume it draws and discharges, recycling 45-65% of wash water cuts both sides of the bill. Our free audit models your actual PUB account rate, trade-effluent charges and recycling potential to give an exact figure for your site.

Commercial laundries in Singapore face high water costs for a few reasons: (1) Singapore prices water to reflect scarcity - the non-domestic potable tariff is SGD$1.43/m³ (April 2025), and the Water Conservation Tax and Waterborne Fee are added on top. (2) Trade-effluent discharge to the sewer is charged separately and rises with higher-strength (high-BOD) laundry wastewater, regulated under the Environmental Protection and Management Act. (3) Most facilities still use fresh water for every wash stage when 45-65% could be recycled. (4) Older washing machines use more water per kilogram than modern equipment. (5) The Water Conservation Tax has been raised over the years and is expected to keep climbing as part of Singapore's water-sustainability strategy. Water recycling with Wientjens Blue Ocean systems reuses suitable wash water across pre-wash and main-wash cycles, cutting metered consumption and discharge volume while keeping fresh water for final rinses.

Wientjens Blue Ocean systems typically reduce water consumption by 45-65%, gas/energy by around 15% through heat recovery, and chemical use by 10-15%. The dollar value of those percentages depends on your volume and your PUB account rate (potable tariff SGD$1.43/m³ from April 2025, plus Water Conservation Tax, Waterborne Fee and trade-effluent charges). As a rule of thumb, the more water you process and discharge, the larger the saving and the faster the payback - high-volume sites can reach payback from as little as 6 months, with most between 6 and 24 months. Rather than quote a generic number, our free audit measures your actual consumption and bills and models the exact annual saving and ROI for your facility.

Water recycling usually gives the largest, fastest reduction for Singapore commercial laundries because it works with your existing washing machines - no machine replacement, with a typical 5-7 day retrofit. Compared with the alternatives: simple efficiency measures (fixing leaks, optimising cycles, staff training) save in the order of 5-10% at little cost; replacing washing machines saves perhaps 10-15% but carries a high capital cost and a multi-year payback. A Wientjens Blue Ocean system targets 45-65% water reduction plus around 15% energy savings from heat recovery, typically paying back in 6-24 months. It also locks in those savings against future Water Conservation Tax increases. PUB's Water Efficiency Fund can co-fund recycling projects (up to SGD$5 million) for eligible sites, which shortens payback further. The best approach is to start with a free audit, implement quick wins, then install recycling for the major long-term saving.

Singapore's water prices have risen steadily over time and are widely expected to keep rising, because the country prices water to reflect scarcity and is investing heavily in NEWater and desalination to reduce reliance on imported water (the water-supply agreement with Johor runs to 2061). The Water Conservation Tax, charged as a percentage of the tariff, has been increased in past tariff revisions as part of this strategy. The practical takeaway for a laundry: recycling 45-65% of your water reduces the volume exposed to every future price and tax increase, so the saving compounds as rates rise. Facilities that invest now lock in a lower cost base and reduce their exposure to subsequent revisions. Our audit shows your current spend and models how recycling protects you against future increases.

Yes. Water recycling is legal and actively encouraged by the Singapore government. Trade-effluent discharge quality is regulated under the Environmental Protection and Management Act (limits on BOD, COD, suspended solids and pH), and PUB promotes industrial water reuse as part of Singapore's water-sustainability strategy. Wientjens Blue Ocean systems use advanced disc filtration (down to 25 microns) to produce water suitable for pre-wash and main-wash reuse, with fresh water retained for final rinses, and reduce both the volume and strength of effluent discharged. PUB's Water Efficiency Fund can co-fund eligible recycling projects (up to SGD$5 million), and sites using 60,000 m³ or more a year must maintain a Water Efficiency Management Plan that on-site recycling supports directly. Our free audit includes compliance review and documentation support, and can scope a Water Efficiency Fund application.
