Water Harvesting & Recycling Technology

Thank you for inviting me to speak today. This is a practical discussion about water harvesting and recycling technology. The framework is simple: protect what you already have, recover what is available at the site, and reuse what you capture. First, Protect. Before a city invests in new supply, it should stop preventable loss. That means identifying leaks, abnormal demand, and avoidable use of treated potable water. Second, Recover. Municipal facilities already receive or generate usable water streams: rainfall from roofs and hardscape, stormwater, HVAC condensate, cooling-tower opportunities, and reusable internal building-water streams. Third, Reuse. With treatment matched to the approved end use, onsite storage, monitoring, and controls, those sources can offset selected demands such as irrigation, flushing, cooling make-up, washdown, and other permitted uses. I will use cooling-intensive facilities and multifamily buildings as two concrete examples, then close with how a city can validate the source, end-use, and economics at one priority site before scaling.
