Responsible Reclamation – City of Abilene, Texas

The City of Abilene, Texas, faced a critical challenge in securing long-term water resilience after prolonged drought conditions began depleting its surface water supplies. To secure its future, the city engineered a major water reuse initiative, reclaiming up to 9 MGD and recharging a primary reservoir.

This project required an advanced treatment approach to handle complex organics and meet strict regulatory standards for reuse. After pilot studies, the city chose a dual-train system, combining Reverse Osmosis (RO) with Ozone (O₃​) + Biologically Activated Carbon (BAC). The O_3​ + BAC train, responsible for 40% of the flow, was selected for its proven efficacy in removing trace organics and endocrine-disrupting compounds (EDCs) at a lower cost than UV or peroxide-based advanced oxidation processes (AOPs). The successful integration of the ozone system, which included modular generators and a high-efficiency side-stream injection process, ensured high performance, low maintenance, and built-in redundancy.

Discover how this flexible, high-performance solution helped Abilene become a regional leader in sustainable water reclamation and reservoir recharge.
