It wasn’t long ago that the average toilet used 3.5 gallons of water per flush. In homes, hotels, and multifamily properties across the country, millions of gallons were literally being flushed away every single day.
Fast forward to today — we’re seeing ultra-high-efficiency toilets that use as little as 0.8 gallons per flush without sacrificing performance. That’s nearly an 80% reduction in water use per flush, thanks to decades of innovation, smarter engineering, and a growing commitment to sustainability.
The Evolution of Efficiency
The journey from 3.5 to 0.8 gallons per flush began in the 1990s, driven by rising water costs and an EPA mandate to reduce water usage to 1.6 GPF. That shift sparked a new era of engineering focused on maximizing performance with half the water. Now, in 2025, water prices continue to rise, the public is more conscious of waste, and performance expectations remain as high as ever. We all want it all—cost savings, environmental sustainability, and top-tier performance at an affordable price. With Niagara’s Stealth Technology®, it’s not just possible—it’s proven.
Engineering Smarter Systems
Modern high-efficiency toilets use advanced designs that optimize water flow, pressure, and bowl hydraulics. Niagara’s Stealth Technology®, for example, uses a unique vacuum-assist system that delivers a powerful, quiet flush — all while using just 0.8 GPF.
The result? A toilet that’s not only more sustainable but also reduces maintenance costs, improves property efficiency, and enhances long-term value for owners.
Why It Matters
With water rates continuing to rise and drought conditions becoming more common, conservation is no longer optional — it’s essential. Every drop saved makes a difference, and when multiplied across hundreds or thousands of fixtures, the impact is huge.
Upgrading from older 3.5 or even 1.6 GPF models to ultra-high-efficiency options can save millions of gallons of water and thousands of dollars in utility costs each year.
