Yesterday, Rich Oller and Wendy Ruiz represented OEI at RuralWaterCon 2026, hosted by the Texas Rural Water Association

The event brings together leaders from across the state to exchange insights, strengthen partnerships, and advance water infrastructure across Texas. As communities continue to navigate growth, funding, and regulatory demands, these conversations play a critical role in shaping practical, forward-looking solutions.

At OEI, we’re proud to support this work through thoughtful planning, design, and infrastructure strategies that help communities build resilient, sustainable systems.

Thank you to the Texas Rural Water Association for an impactful event. We look forward to continuing the conversation.
