For the past several years, R2T has completed several projects (listed below) for Cobb County-Marietta Water Authority (CCMWA) under general services and demand services contract.
James E. Quarles WTP Reliability Improvements. R2T served with CCMWA staff and provided daily and overall project management with coordination and input from the CCMWA staff to complete a $20M+ rehabilitation of existing facilities including flocculation basins, sedimentation basins, filters and appurtenances, sludge handling, yard piping, and clarification equipment.
Filter Press Sludge Feed Pumps. R2T developed a design that allowed the installation of two proposed DISCFLO type sludge/slurry pumps and variable speed drive at the Quarles WTP sludge handling facilities without impacting capacity of the existing sludge facilities.
Quarles and Wyckoff WTP Liquid Lime Feed System. R2T provided design and construction management services for a liquid lime system at the Quarles Water Treatment Plant to replace existing lime feed systems. At Wyckoff WTP, our team designed a new containment liquid lime system to replace the current hydrated lime system used for sludge conditioning. The design included structural, piping, process equipment design, electrical, and controls.
Raw Water Intake and Pump Station. Existing raw water pump station was equipped with four traveling screens and two rake screens that were installed as part of a recent expansion. Over two phases, R2T provided preliminary, detailed design, permitting, bidding and construction phase inspection and technical support services to remove and replace the existing traveling screens. Significant permitting and coordination with GDOT were required due to proximity to major DOT river overpass.
Factory Shoals Pump Station Electric Improvements. R2T prepared contract documents and design to upgrade electrical controls and routing locations at the Factory Shoals Pump Station in Austell, GA.
CCMWA Strategic Planning. R2T completed a department-wide strategic plan for CCMWA by completing a review and assessment of daily functions and interdepartmental coordination of all departments within CCMWA. R2T developed a series of recommendations to improve and optimize several departments.
Demand Forecasting. R2T is currently engaged in projecting future water system demands at a local resolution for incorporation into a hydraulic model and capital improvement plan.
Wyckoff WTP Raw Water Replacement. R2T provided engineering services for the replacement of Pump RW-5 at the Raw Water Pump Station, including hydraulic analysis of the raw water piping system and a VFD study.
Wyckoff WTP SSEQ Decant System. R2T designed a new wet well and pump station outside of the existing SSEQ basin to provide a permanent solution to process decant water. The design included structural, piping, electrical, and controls to the new pump station.
