Grey Water Plant – (TRUF)
The TRUF Grey Water Treatment Plant is a plug-and-play system that transforms wastewater from sinks, showers, and laundries into reusable water for irrigation, toilet flushing, and car washing. Unlike conventional systems, it combines three advanced stages—ultra filtration, multi-media filters, and activated carbon polishing—to remove 99% of contaminants while meeting DEWA (UAE) and SASO (KSA) standards. Ideal for hotels, malls, and industrial sites, this compact solution cuts water costs by up to 50% and requires minimal maintenance. Plus, optional IoT monitoring lets you track performance remotely.

Description
TRUF Grey Water Treatment Plant – Sustainable Water Reuse for UAE & KSA
Complete Plug-and-Play Solution
Unlike conventional systems, Triwa’s TRUF Grey Water Treatment Plant doesn’t just filter wastewater—instead, it transforms water from sinks, showers, and laundries into reusable water for irrigation, toilet flushing, and car washing. What’s more, our all-in-one system combines ultra-filtration, multi-media filters, and activated carbon polishing to meet DEWA (UAE) and SASO (KSA)standards. As a result, you get compliant, odor-free, and non-potable water with minimal maintenance.
How the TRUF System Works
-
Pre-Treatment
-
First, automatic screens remove hair, lint, and large particles.
-
-
Ultra-Filtration (UF)
-
Next, hollow-fiber membranes filter contaminants down to 0.01 microns, which means 99% removal of bacteria and turbidity.
-
-
Activated Carbon Polishing
-
Finally, carbon filters eliminate detergents, oils, and odors for crystal-clear output.
-
✅ Key Benefit: Not only is the system fully automated, but it also offers IoT monitoring options to track flow rates, filter life, and water quality remotely.
Applications & Cost Savings
| Use Case | Water Quality | Savings |
|---|---|---|
| Landscape Irrigation | Thanks to ultra-filtration, water achieves turbidity <5 NTU and BOD <10 mg/L | Consequently, freshwater use drops by 50% |
| Toilet Flushing | Because of thorough polishing, water is odor-free and pathogen-free | Therefore, sewer discharge fees fall 30% |
| Car Washing | After treatment, water is oil-free with low TDS | Ultimately, you’ll use 100% recycled water |
Why Choose TRUF?
-
Fast Deployment: Unlike custom-built systems, our pre-assembled skids become operational in 24 hours.
-
Compact Design: Despite its high capacity, the system fits tight spaces (from 2.5 m²).
-
Certified Compliance: In addition to meeting DEWA standards, TRUF is SWCC-approved for Saudi Arabia.
-
Low Energy: Compared to traditional plants, it runs on <1 kW per 1,000 liters.

Where TRUF Grey Water Plants Are Used
TRUF units are sized for buildings and sites that produce a steady flow of grey water from showers, wash basins, ablution areas and laundries. Typical projects in Saudi Arabia and the UAE include:
- Hotels, resorts and serviced apartments – reuse shower and basin water for landscape irrigation and toilet flushing.
- Residential compounds and towers – cut potable water demand and municipal water bills.
- Labour accommodation and construction camps – treat grey water on site where sewer connections are limited.
- Mosques and ablution facilities – recover clean ablution water for irrigation.
- Schools, malls, offices and car wash facilities – meet green building and water reuse targets.
Grey Water vs. Sewage Treatment: Which Plant Do You Need?
Grey water excludes toilet and kitchen waste, so it can be treated with a compact filtration train such as TRUF instead of a full biological plant. If your site needs to treat combined sewage (black water), choose a packaged MBBR sewage treatment plant instead. Our engineers can also combine both: a TRUF unit for grey water reuse and an MBBR plant for sewage.

Grey Water Treatment Plant – FAQs
What can treated grey water be used for?
Treated grey water from a TRUF plant is non-potable water suitable for landscape irrigation, toilet and urinal flushing, car washing and cooling or cleaning uses, subject to local authority requirements.
Does the TRUF system meet UAE and Saudi standards?
TRUF is designed to meet DEWA requirements in the UAE and SASO requirements in Saudi Arabia for non-potable reuse. The final design is confirmed against your project’s water quality and authority approvals.
How much space does a grey water plant need?
Because TRUF is a compact skid, it fits in plant rooms, basements or a small outdoor area. Footprint depends on capacity; share your daily flow and we will send a layout.
