In this edition of The Oller Edge, we're highlighting the people, projects, and partnerships shaping stronger infrastructure across Texas. From engineering insights on wastewater design and a featured project moving into construction, to welcoming new talent and connecting with municipal leaders, OEI remains committed to delivering practical solutions that help communities solve today's challenges while planning for tomorrow's opportunities.

Engineering Insights with Dr. Clifford Fedler

Featured Webinar: Could Your Water Balance Be Costing You More Than It Should?

Water balance drives some of the most important decisions in wastewater land application design, impacting irrigation requirements, storage capacity, land needs, and overall project costs. In this educational webinar, Dr. Clifford Fedler explains the principles behind water balance calculations, compares leading design methodologies, and shares practical insights to help municipalities and engineers design more efficient, cost-effective wastewater systems.

Projects That Move Communities Forward

From Design to Construction: Pancake Plant Renovations Begin

The Coryell City Water Supply District's Pancake Plant Renovations have officially entered the construction phase. OEI partnered with the District to develop a scalable, TCEQ-compliant design that expands capacity, modernizes critical infrastructure, and supports reliable operations for years to come. It's another example of how thoughtful engineering helps communities invest confidently in their future.

Growing Our Team. Strengthening Our Impact.

Say Hello to the Newest Faces at OEI

We're excited to welcome two new members to the OEI team! Mechanical Engineer Jeremy Serpa brings a strong foundation in mechanical design, 3D CAD modeling, and technical problem-solving, while Engineering Intern Angie Lemus is pursuing a degree in Civil Engineering and gaining hands-on experience in infrastructure design and engineering analysis. Together, they represent the next generation of engineering talent, strengthening our team and helping us better serve our clients and communities.

Leading Conversations That Shape Texas Communities

OEI at TML 2026: Connecting Across Texas (November 11-13 in San Antonio, TX)

The OEI team will be attending—and proudly sponsoring—the Texas Municipal League Annual Conference & Exhibition November 11-13 in San Antonio. As communities across Texas continue to navigate growth, aging infrastructure, and evolving funding opportunities, we look forward to engaging with municipal leaders on the strategies and partnerships needed to support long-term success.

Whether reconnecting with existing partners or building new relationships, we're excited to continue the conversations that help strengthen communities across Texas. If you'll be attending, we'd welcome the opportunity to connect.
