On-call Wastewater Engineering Services

Since 2019, Grayling Engineers has supported Clark Regional Wastewater District under an ongoing on-call contract, providing planning, hydraulic analysis, and design services focused primarily on pump station assessments, rehabilitation, and replacement projects, as well as targeted sewer main upgrades.

Our work includes system-wide hydraulic evaluations, transient analysis, pump upsizing and selection, air/vacuum valve improvements, wetwell rehabilitation, and small-diameter pipeline replacements. Representative projects include multi-station hydraulic studies along Hillhurst Road, pump station redirection and force main reconfiguration, sewer main replacement along South 7th Avenue, and multiple pump station rehabilitation and capacity improvement efforts throughout the District.

Through responsive, task-based support, we help the District improve system performance, address operational challenges, and plan for long-term growth.
