This April Fools’ Day, here’s one thing that isn’t a joke: “Flushable” wipes don’t break down like toilet paper. They build up in sewer systems, damage equipment, and create costly challenges for utilities. Protect your pipes and your local system: only flush toilet paper.

Progress in the water industry doesn’t happen all at once; it happens through conversations, shared experiences, and lessons learned over time. For Women’s History Month, WaterWorld Magazine brought together voices from across the sector to reflect on career growth and leadership. In the article, Carollo Executive Vice President Anne Prudhel highlights an important reminder: if you don’t communicate your career goals, even the best mentors may miss the chance to support them.

Wastewater-based surveillance has become an important tool for tracking public health trends, but making sense of the data depends on the biomarkers we use. A recent peer-reviewed study co-authored by Carollo’s Aiswarya Rani Pappu, PhD and Scott Montgomery, published in American Chemical Society ES&T Water, examined why pepper mild mottle virus (PMMoV) levels vary so widely in wastewater across the U.S. Their findings offer valuable insights for improving pathogen normalization and strengthening data-driven public health models.

Tampa is moving forward with a historic upgrade to its drinking water system. The Tampa City Council has approved funding for the design of Suspended Ion Exchange (SIX®) technology at the David L. Tippin Water Treatment Facility, set to become the largest installation of this technology in the world and the first full-scale implementation in the United States. The system is being designed to treat up to 140 million gallons per day, improving water quality, reducing chemical use, and helping the City of Tampa prepare for future regulatory requirements. Carollo Engineers is serving as the lead designer on a collaborative design-build team with Garney and Wharton-Smith, Inc.

Design-build projects bring together engineers, contractors, operators, and specialty partners, each with distinct perspectives on risk, responsibility, and project delivery. In a recent article published by the Water Collaborative Delivery Association, Carollo’s Chitra Foster, P.E., DBIA, ENV SP discusses how successful primes act as “bilingual leaders,” translating between disciplines to clarify risk, align teams, and strengthen collaboration. Her insights highlight why communication and thoughtful risk allocation are essential to keeping complex design-build projects on track and delivering value to owners.

Corrosion control is entering a new chapter under the Lead and Copper Rule Improvements (LCRI), and many utilities are asking where to begin. To help answer that question, the American Water Works Association has released the Corrosion Control Implementation Framework. Prepared by Carollo’s Caroline Russell and Jerry (Chenxu) Yan, PhD, PE in partnership with Cornwell Engineering Group, Inc., this new guidebook offers a clear, step-by-step roadmap to help utilities implement, optimize, or reoptimize corrosion control treatment using system-specific data and practical decision points. Designed to support both utilities and regulators, the Framework aligns with LCRI requirements while remaining flexible enough to apply beyond compliance alone. Learn more: https://lnkd.in/ggg5RVa5
