Gravel Ridge WWTP

TOLM Group partnered with Gravel Ridge Sewer Improvement District (SID) #213 to complete improvements to its wastewater treatment facility in Pulaski County, Arkansas. Serving approximately 1,500 customers in the Gravel Ridge and Jacksonville area, the utility sought to enhance treatment capabilities, improve operational reliability, and support continued quality service to the surrounding community. 

The project included construction of a new 91-foot-diameter clarifier/aerator tank, associated piping, and supporting treatment infrastructure. With the existing plant required to remain operational throughout construction, TOLM carefully coordinated activities with plant operators and scheduled critical work around limited shutdown windows to minimize service disruptions. 

Despite pandemic-related supply chain challenges and extended material delivery times, TOLM worked proactively with vendors and adjusted construction sequencing to keep the project moving forward. By identifying opportunities to accelerate portions of the work, the team successfully completed the project on time and within budget. 

The confined project site also required additional planning to ensure safe operations and minimize impacts on neighboring properties. TOLM implemented site-specific safety measures, coordinated material deliveries, and maintained dust control throughout construction. Quality assurance remained a priority, with third-party testing, soil compaction verification, hydrostatic pipe testing, and multiple inspections during construction of the clarifier/aerator tank. 

Through proactive planning, quality workmanship, and strong collaboration with the owner and engineering team, TOLM delivered an improved wastewater treatment facility that strengthens operational reliability and supports dependable wastewater service for approximately 1,500 customers in the Gravel Ridge community.
