Graywater Recycling
Premium German Engineering Meets Next-Gen Water Recycling
Leverage nearly 30 years of pioneering European expertise and precision German engineering with Dehoust gray water systems.
Gray water is available every day — even when it hasn’t rained. Unlike rainwater harvesting, gray water provides a predictable, weather-independent resource to help your projects achieve Net-Zero Water goals. Gray water includes wastewater from bathtubs, showers, bathroom sinks, and washing machines. Utilizing advanced biological-mechanical treatment, the Dehoust GWM and Gwtec® series safely transform this discharge into hygienically pure, non-potable water.
This reclaimed water is perfect for meeting commercial non-potable demands, including toilet flushing, laundry facilities, landscape irrigation, and cooling tower make-up water.
Unlock Florida Density Bonuses & Maximize Land Value
For developments in Florida, integrating Dehoust's European-engineered technology provides an unprecedented regulatory and financial advantage. Under Florida Statute § 403.892, residential and multi-family projects (with at least 25 units) qualify for significant density and intensity bonuses:
- 35% Density Bonus: Granted to developers who install gray water systems serving 100% of the development.
- 25% Density Bonus: Granted to developers who install gray water systems serving at least 75% of the development.
By deploying a certified, centralized Graywater system, you can build up to 35% more units on the same footprint, drastically increasing your project's Gross Revenue and ROI.
Accelerate Your LEED® Certification & Green Building Goals
The Dehoust GWM and Gwtec product lines combine decades of German innovation to maximize your property's sustainability scorecards. They fully comply with stringent US green building standards:
- LEED Water Efficiency (WE) Credits: Reduce indoor potable water use and outdoor water consumption by up to 60%, unlocking maximum points in municipal water use reduction.
- LEED Energy & Atmosphere (EA) Credits: Capitalize on waste-water heat recovery to lower building energy intensity.
- Versatile Applications: Designed for seamless, scalable integration into multi-family residential complexes, high-rise developments, hotels, student housing, and commercial fitness centers.
With nearly three decades of global engineering experience, Dehoust is a pioneer in decentralized water recycling. We empower architects, MEP engineers, and developers to deploy the most efficient, reliable, and compliant green tech on the market. (Note: Always review local plumbing codes and operating guidelines).

High-Performance ROI: Water & Sewer Cost Reductions
Reusing gray water cuts municipal potable water consumption and subsequent sewer fees by up to 60%. This dual-benefit approach slashes your property’s operational expenses (OpEx), mitigates rising utility risks, and significantly boosts your asset's ESG performance and overall market value.
Smart Energy Management: Advanced Heat Recovery
Maximize your green building efficiency by capturing thermal energy right from the source. The Gwtec platform seamlessly integrate with wastewater heat recovery systems. By utilizing a specialized heat pump, thermal energy from the warm drain water is reclaimed and fed back into your domestic hot water loop.
This eco-friendly process slashes both your water footprint and your building’s carbon emissions simultaneously.
