Data centers make this post possible, and Jack Malace, PE and Emma Feldman at Carollo Engineers, presenting at UltraFacility 2025, are showing how they're making data centers sustainable and possible with water stewardship. The global water crisis is here, and their work, one data center at a time, is critical to the success of the digital economy.

The ABC's of Water Reuse? We all enjoy scrolling LinkedIn for the latest #waterindustry news, whitepapers and data analyses to offer invaluable insights to our community of #waterprofessionals, right? However, sometimes the deeper we get into the depths of the water industry, we are reminded that foundational, entry-level terminology learned in our earlier years of #watertreatment remains crucial. Whether discussing measurement and control technology or #waterreuse processes, our field frequently utilizes complex jargon that can benefit from being broken down into simple, accessible definitions for new professionals or seasoned veterans. Carollo Engineers has done a great job addressing this need by publishing "The ABCs of Water Reuse". The guide reflects an understanding of water reuse and the common terminology we hear every day in a simple, easy-to-understand manner.

💧 Big news out of North Texas The $202.5M Phase 2 expansion of the Tom Harpool Regional Water Treatment Plant is officially moving forward, and it’s a standout example of what collaboration in our industry should look like. This project will double capacity to 60 MGD by 2028, supporting one of the fastest-growing regions in the country. And it’s being delivered with a level of planning, partnership, and technical ambition that deserves recognition. Upper Trinity Regional Water District leading long-range planning for 29 cities and utilities as population projections climb toward 1M+. McCarthy Building Companies, Inc. serving as CMAR and navigating the complexity of 30+ major tie-ins while keeping the existing plant fully operational. Their phased approach, self-perform capabilities, early procurement strategy, and coordination across GMP packages set the tone for execution. Carollo Engineers, the design engine behind the expansion. From membrane treatment integration to gravity-fed loops and energy-efficient flash mix systems, Carollo continues to lead with technical depth and future-ready thinking. As North Texas continues its rapid growth, investments like Harpool Phase 2 aren’t just capital projects...they’re lifelines. And this team is setting a benchmark for what’s possible when design, construction, and public agencies move in lockstep. A huge congratulations to every partner involved. https://lnkd.in/ems47p9f
