Willow Creek Sewage Treatment Improvements
Replacing an Aging System the Right Way
Service: On-Site Water & Wastewater Systems
The Challenge
The Willow Creek Sewer District's original mechanical treatment plant had reached the end of its useful life and needed replacement. Rather than a straightforward swap, the right path forward required a formal facility plan study to evaluate all viable treatment options — each with different site requirements, cost profiles, and long-term implications for the community.
Our Solution
Gaston Engineering & Surveying completed the facility plan study and recommended a lagoon system as the most cost-effective solution. Multiple sites were evaluated and value-engineered before the optimal location was selected. We then designed the full system, including lined lagoon cells, a pumping station, flow meters, and UV disinfection. We submitted the design to MDEQ for review and approval. Construction included revision of the existing lift station and full decommissioning of the original package plant.
