Water Quality Control Facilities Improvements Design

complete / design

The combined sewer system located in a 15-square-mile area of the City, which is centered in downtown Atlanta. The combined sewer area includes the North Avenue, Tanyard Creek, Clear Creek and Custer Avenue Combined Sewer Basins. During some storm events, combined sewer flows that exceed the downstream Water Reclamation Center (WRC) treatment capacity and the ability of the collection and transmission system storage facilities is directed to either Water Quality Control Facilities (WQCFs) or Combined Sewer Control Facilities (CSCFs) for treatment. The City owns and operates two WQCFs four CSCF’s, and one combined sewer Regulator facility. These facilities operate under two separate National Pollutant Elimination System (NPDES) permits. One permit covers the East Area Facilities which discharge into the South River basin; a separate permit covers the West Area Facilities which discharge into the Chattahoochee River basin. In 2014, a task order was awarded to an Architectural/Engineering Joint Venture to prepare designs for renewal and replacement of aging, outdated or nonfunctioning equipment at each WQCF. The scope of this project includes: Evaluating renewal and replacement requirements at WQCFs Preparing preliminary and detailed designs Preparing opinions of probable construction costs Grouping projects into short-term and long-term priorities Preparing bid documents for most critical equipment at WQCFs Justification: Replaces aging, outdated or nonfunctioning equipment at WQCFs Design improvements facilitate compliance with permit requirements Improves efficiency and reliability Improves safety at facilities
