Halff’s Gravel Ridge SID Work Earns ACEC Arkansas Honor Award
LITTLE ROCK, Ark. — Halff earned an American Council of Engineering Companies (ACEC) Arkansas Honor Award for its Gravel Ridge Sewer Improvement District work in the water and wastewater category.
Gravel Ridge’s wastewater facility, SID 213, opened in 1975 and included facultative lagoons that treated wastewater for 1,500 customers in northern Pulaski County, including residents in Gravel Ridge and portions of Jacksonville and Sherwood.
The Arkansas Department of Environmental Quality (ADEQ) recently increased water quality standards to a level SID 213 could no longer achieve.
Halff designed a new treatment facility using the existing facultative lagoons. A new influent pump station was utilized for wet weather flow and sludge storage, allowing the facility to achieve maximum efficiency. An innovative sludge process designed by Halff enables the treatment plant to provide quality effluent and a clean environment with opportunities for future capacity growth.
The Gravel Ridge honor is Halff’s second ACEC Arkansas accolade in the water and wastewater category in last three years. Halff’s Bull Shoals Wastewater Treatment Plant garnered recognition in 2021.
