Old fashioned water softeners have been identified as a major problem for waste water authorities across the Southwestern US. Because the re-use of discharged waste water is now being viewed as a sustainable water supply, water reclamation authorities have been mandated by Regional Water Board(s) to reclaim and reuse as much waste water as possible. Therefore, the salt that is discharged from self-regenerating water softeners has come to be viewed as a significant source of pollution. Our challenge, the problem we have undertaken -- how to soften water without relying on salt. The Puroserve HT Series Whole House Water System achieves the goal of providing clean, softened water for home or commercial use through the use of low energy, high-production Reverse Osmosis membrane technology. With the HT Series, you can enjoy both gentle soft water and highly-purified water for drinking and cooking. Moreover, with our innovative wastewater diversion techniques, over 95% of all salt sources never reach the waste water (sewer), system. This technology has the potential to reduce ALL sources of salt, including tap water salts, benefitting waste water authorities challenged with managing salt sensitive watersheds. Choose the Puroserve model that's perfect for you!
