Company invested a record $791 million in water and wastewater infrastructure in 2025, achieved 99.91% regulatory compliance, and is accelerating a $450 million PFAS capital plan to protect drinking water quality across eight states

Essential Utilities, Inc. (NYSE:WTRG) joins communities across North America in celebrating Drinking Water Week (May 3–9, 2026), the annual observance led by the American Water Works Association (AWWA) that recognizes the critical role safe, clean drinking water plays in public health and quality of life.

As the company marks this year's celebration, Essential Utilities reflects on a year of record performance through its water utility, Aqua – delivering safe, reliable water service to more than 1.1 million customers across eight states while investing nearly $791 million in water and wastewater infrastructure, the largest annual capital investment in the company's history.

"Drinking Water Week is a chance to recognize what our teams deliver every day: safe, clean, reliable water to millions of families, businesses and communities who depend on us," said Christopher Franklin, chairman and CEO of Essential Utilities. "In 2025, we set a new record for infrastructure investment, advanced our comprehensive PFAS remediation program, and maintained industry-leading compliance rates. We operate every day in the pursuit of excellence, and this is what it looks like."

Aqua's water operations achieved a 99.91% compliance rate in 2025, consistently outperforming national benchmarks for water quality and reflecting the company's rigorous approach to monitoring, treatment and distribution. That commitment is backed by a state-of-the-art Environmental Laboratory in Bryn Mawr, Pennsylvania, and more than 1,500 Aqua employees, including water quality scientists, engineers and field operators, who work 24/7 to ensure customers receive water that meets or exceeds federal and state standards.

The company is also a national leader in addressing PFAS contamination, executing a $450 million multi-year capital plan to ensure finished water does not exceed federal maximum contaminant levels for the six EPA-regulated PFAS chemicals.

Investing in the Future

Essential Utilities invested a record $1.4 billion across its regulated water and natural gas systems in 2025 and has committed to $1.7 billion in infrastructure investment in 2026. These investments modernize aging pipelines, fund treatment plant upgrades, and improve monitoring technology to ensure safe, reliable service for future generations.

Beyond the pipes, Essential is a dedicated steward of the natural lands and watersheds that make safe drinking water possible. The company protects thousands of acres of forests and sensitive habitats throughout its footprint.
