Installation Process in Singapore: Retrofit to Existing Equipment
No need to replace your washing machines. Our systems retrofit seamlessly to your existing equipment with minimal disruption. Most installations complete in 5-7 days.
Singapore installation process
Key facts at a glance
This page sets out what a Wientjens Blue Ocean retrofit involves for a Singapore laundry — working into the washers, drains and water lines already in your plant room rather than starting over.
It speaks to operators watching the PUB tariff and chasing their Water Efficiency Management Plan targets: hotel, hospital and aged-care laundries, textile-rental plants and industrial sites that want water reuse and heat recovery without disturbing the wash floor.
- Where we work: commercial laundries across Singapore, including compact high-rise plant rooms.
- On-site time: 5-7 days for the usual retrofit; the largest plants run to 7-10 days.
- No washer changes: the loop sits behind your washer-extractors and tunnel washers — none are replaced.
- What it covers: assessment and design, delivery, prep, PUB-licensed plumbing and electrical, commissioning, testing, training and support.
- Local context: PUB S$1.43/m³ non-domestic tariff, SS 636 certification, WEMP metering and the Water Efficiency Fund.
- What we offer: a free Singapore pre-installation assessment and ROI analysis.

Installing in Singapore
Approvals, connections and compliance specific to Singapore
A Singapore retrofit follows the same Wientjens timeline as anywhere else, but the connections to your water supply are regulated locally. We coordinate the work so the system is commissioned cleanly and your potable supply stays fully compliant.
PUB Licensed Plumber connections
Since 1 April 2018 all regulated water-service work in Singapore must be carried out by a PUB Licensed Plumber, who issues a Certificate of Satisfactory Completion certifying the installation to the Public Utilities (Water Supply) Regulations and Singapore Standard SS 636. We schedule a licensed plumber for the supply-side tie-ins.
Sub-metering for your WEMP
If your site uses 60,000 m³ or more a year, PUB requires private sub-meters at key usage areas as part of a Water Efficiency Management Plan. We position metering during installation so recycled-versus-fresh volumes are captured from day one and feed straight into WEMP reporting.
Potable supply stays protected
Recycled-water lines run as a separate circuit from your PUB potable supply, and final-rinse cycles stay on fresh mains water. That keeps drinking-water standards intact while still cutting 45–65% of your metered consumption — important for compact, high-rise Singapore plant rooms where the modular Wientjens skids fit without major civil works.
Step by Step
Week-by-Week Installation Timeline
A clear schedule from first site visit to go-live, designed around your operations.
Week 1: Assessment & Planning
Activities:
- Inspect the plant room and connection points
- Measure the washers and the room available
- Sample the discharge for pH and solids
- Design the system around your tonnage
- Plan WEMP metering and confirm dates
Your Role:
- Give our assessor access to the wash floor
- Share your shift pattern and busy periods
- Approve the design we propose
- Choose install dates that fit you
Time Required: One visit of 2-3 hours
Week 2: Preparation & Pre-Works
Activities:
- Order the unit and deliver it to site
- Add any power circuits the unit requires
- Rough in the supply and drain points
- Mark out the mounting and anchor points
- Arrange building-owner approvals if needed
Your Role:
- Keep the install area free for the crew
- Liaise with building management on access
- Otherwise carry on with production
Disruption: Light — prep largely runs off-peak
Week 3: System Installation (Days 1-5)
Day 1-2: Physical Installation
- Manoeuvre the main unit into place (Blue Ocean, AquaMiser, or AquaBatch 3)
- Set up the filtration and buffer tanks
- Mount the control panels and sensors
- Fasten the gear to the floor
Day 2-3: Plumbing Integration
- Connect into the washers' discharge lines
- Run the rinse-water capture pipes
- Pipe recycled water back to the inlets
- Connect to existing hot water (if using Blue Ocean HEX)
- Fit AquaDrain backflush filtering (where specified)
- Pressure-test the lines and keep the potable supply separate
Day 3-4: Electrical & Controls
- Bring power to the unit
- Wire the pumps, valves and sensors
- Load and check the PLC controls
- Tie into the washer controllers
- Fit the operator displays
- Turn on data logging for WEMP reporting
Day 4-5: Testing & Commissioning
- Fill, prime and clear air from the circuit
- Run all pumps and valves through their cycle
- Calibrate the sensors and thresholds
- Process live loads on recycled water
- Confirm water quality holds within spec
- Tune the reuse rate for the best saving
- Log the baseline numbers for handover
Flexible Scheduling: The disruptive work fits into nights, weekends or off-peak hours, so a Singapore hotel or hospital laundry keeps washing through almost all of the build.
Week 4: Training & Go-Live
Activities:
- Deliver a 2-3 hour operator session
- Walk the team through daily running
- Outline the maintenance the unit needs
- Cover everyday fault-finding
- Set up monitoring and WEMP reporting
- Hand across the documentation
What You'll Learn:
- Powering the system on and off
- Interpreting the control display
- Cleaning the filters
- Recognising when to call support
- Tracking water quality
- Keeping to the service intervals
Support Included: A 30-day on-site window with weekly check-ins

How Integration Works
The loop sits between your machines, the PUB supply and the drain. Five steps put each batch of water back to work:
- 01 Intercept: rinse water is taken to the recycler instead of running to trade effluent
- 02 Filter: disc filtration removes lint, fibre and fine solids
- 03 Store: the treated water sits in buffer tanks until needed
- 04 Recycle: it returns to pre-wash and main-wash stages, with final rinses kept on fresh PUB mains
- 05 Control: sensors and automated valves hold quality steady and run it without intervention

FAQs
Common Installation Questions
Everything you need to know before starting your installation journey.
Will installation disrupt my operations?
Very little — we shape the schedule around how your laundry runs:
- Overnight work: the crew comes in during the 10pm-6am lull
- Weekend slots: the major tasks go in while you're closed
- Group by group: machines are switched over in batches so others stay live
- Mains on hand: any washer can fall back to fresh supply instantly
Most Singapore laundries hold 80-100% of normal output right across the install.
How long does installation actually take?
The chosen unit drives the timeline:
- AquaMiser: 3-4 days to commissioning
- Blue Ocean: 5-7 days, testing included
- AquaBatch 3: 7-10 days on the more demanding sites
That covers the build, integration, testing and training. The upfront design and assessment runs a week or two separately and never disrupts production.
What if I don't have enough space?
Tight high-rise plant rooms are the norm here, and there's usually a fit:
- Go compact: the AquaMiser asks for just 3m² (2m × 1.5m)
- Stack vertically: components mount upward to save floor area
- Site it outside: the unit can go in an external bay when indoor room is gone
- Shape to suit: the skid layout adapts to the room you have
- Place apart: tanks can sit away from the wash floor on a pipe run
The site assessment is where we pin down which of these works for your building.
Can you work with my existing washing machines?
Yes — the loop connects behind any commercial washer-extractor or tunnel washer, so your existing machines stay in service.
What's included in the installation cost?
The one turnkey price takes in:
- Equipment: pumps, tanks, filters and controls
- Labour: the licensed install team for the whole build
- Materials: pipe, valves, cabling and fittings
- Integration: hooking up to your machines and services
- Commissioning: testing, calibration and tuning
- Training: a 2-3 hour operator session
- Documentation: O&M manuals, as-builts, warranty and the SS 636 completion certificate
Billed separately: any building-owner or authority fees (we handle the process), mains supply upgrades, and structural work — rarely needed.
What happens if something goes wrong during installation?
Safeguards are built in at each stage:
- Fall back to mains: washers can switch to fresh PUB supply immediately
- Daily contact: progress reports each day, and an immediate flag if anything arises
- Practised crew: hundreds of retrofits already behind the installers
Your laundry ends each day operational, and the 12-month warranty covers any defect in the install.
How much training do my staff need?
Little — the system is largely self-running:
- Operators: a single 2-3 hour hands-on session
- Maintenance staff: a further hour on the advanced functions
Within a week or two the crew runs it without thinking; the controls handle the routine on their own.
