DECEMBER 2018

Water Supply Program Quarry/Chattahoochee/Hemphill

Update: Crews are cleaning and lining the interior of the tunnel with concrete liner. Construction of the Quarry and Hemphill Pump Station will continue and controlled blasting at the Hemphill Water Treatment Plant is scheduled to be complete by December 2018. The Water Supply Program will increase Atlanta’s reserve water supply from three to five days to 30 to 90 days. The $300 million investment includes the construction of a five-mile tunnel connecting the Chattahoochee River, the Hemphill Water Treatment Plant, and the former Bellwood Quarry, which will be transformed into a 2.4 billion gallon reservoir. The Water Supply Program is scheduled for completion by September 2019.   Expected Completion: September 2019 Project Location: Northwest Atlanta Council District(s): 3, 9 Neighborhood Planning Unit(s): C, D, G, J, K

Clear Creek West Sewer Improvements Project Civic Center Vault

Update: Crews continue to pour the walls and foundation of the vault. The City of Atlanta's Department of Watershed Management has identified the need for an underground storage vault to be installed to increase the storage capacity of the existing combined sewer system in the Clear Creek West basin. The vault associated with this project is located in the southeastern corner of the existing Civic Center parking lot adjacent to Ralph McGill Boulevard. The Butler Street trunk and relief combined sewers drain the upper section of the west Clear Creek basin. During certain rainfall events this system can become surcharged, which may result in flooding. The storage vault will store excess combined sewer flows from the Butler Street Relief Combined Sewer, which intercepts at the I-75/85 entrance ramp from Freedom Parkway and Highland Avenue. Stored combined sewer flow in the vault will reduce the peak flow in the downstream combined sewer helping to reduce flooding. This stormwater vault will help manage rainfall runoff from the adjacent federal highways and downtown portions of the basin. Additionally, implementation of green infrastructure projects are proposed to further manage combined sewer peak flows to the combined sewer system and to reduce the required capacities of the vaults.   Expected Completion:  March 2019   Project Location: Northeast Atlanta   Council District(s): 2   Neighborhood Planning Unit(s): M, E

Upper Proctor Creek Capacity Relief Project Rodney Cook Sr. Park In Historic Vine City

Update: The Upper Proctor Creek Capacity Relief project: Rodney Cook, Sr. Park in Historic Vine City is a multi-phase effort to reduce flooding and combined sewer flows in the Vine City neighborhood.  This project consists of a collection of innovative stormwater practices designed to redirect surface runoff away from the Beckwith Trunk and Mineral Springs combined sewer systems. The capacity relief facility is currently under construction led by the Astra/Rohadfox, Joint Venture.  The components of this project include a 2-acre pond (9+ MG capacity), green infrastructure (bioretention, stormwater planters, rainwater harvesting cisterns, and soil restoration), aerating water features, separated storm drain pipelines, new sidewalks and roadway improvements.  The Department of Watershed Management is working concurrently with The Trust for Public Land who is responsible for the build out of the adjacent park. In addition, The National Monuments Foundation will be constructing statues of historic figures throughout the finished park.   Expected Completion: March 2019 Project Location: Vine Street NW Council District(s): 3 Neighborhood Planning Unit(s): C, D, E, G, H, I, J, K, L, M T

Proctor Creek Sewer Basin Ashby-Jett Sewer Improvement Project

Update:  The Purpose of this project is to upsize the existing Ashby-Jett outfall from 18-inches to 30-inches. Upsizing the outfall will provide capacity relief and reduce the surcharge conditions in the existing trunk line. The project includes upsizing the existing line through open cut methodology west of the existing CSX railroad to where the sewer discharges into the 48” Proctor Creek Trunk.  Trees were planted in Fall 2018.     Expected Completion:  March 2019   Project Location(s):  Bankhead, Hills Park, Center Hill, Grove Park, Washington Park, Hunter Hills Knight Park   Council District(s):  3   Neighborhood Planning Unit(s):  L, K

Peachtree Creek Sewer Basin Peachtree Creek Trunk Stabilization

Update:  The City of Atlanta is continuing its implementation of a comprehensive program to upgrade its existing sanitary sewer system to eliminate wet weather sewer overflows. To accomplish this, the Peachtree Creek Trunk sewer, which traverses through Atlanta Memorial Park and neighboring Bobby Jones Golf Course will be cleaned then rehabilitated by installation of an interlocking grouted PVC profile structural liner as a permanent solution to ensure the long-term structural integrity and service life of the sewer, an existing 96-inch arch shape concrete pipe. The winding machine rotates and traverses within the pipe, interlocking the PVC profile together against the host pipe wall. The process requires only a manhole or existing access chambers for rehabilitation.  To date, the cleaning process has removed approximately 1,700 tons of debris. The lining process is underway utilizing the new Spiral Wound technology. Spiral Wound is an innovative technology for rehabilitating pipelines without digging, producing a tight-fitting line with no grout required.   Expected Completion:  September 2019   Project Location(s): Atlanta Memorial Park, Brandon, Cross Creek, DeFoors Ferry, Hanover West, Peachtree Battle, Ridgewood Heights, Wesley Battle, Westover Plantation, Wildwood, Woodfield   Council District(s):  8, 9   Neighborhood Planning Unit(s):  C, D

Clear Creek Combined Sewage Control Facility

Update:  Clear Creek Combined Sewage Control Facility (CSCF), one of the combined sewer control systems owned and operated by the City, is located in the West Service Area of the City of Atlanta. During large storm events, when the capacity of the tunnels and the West Area WQCF are exceeded, the combined flows enter the Clear Creek CSCF and the combined wastewater is treated through coarse bar screening and fine drum screening, disinfected with sodium hypochlorite (NaOCl) and dechlorinated with sodium bisulfite. Upgrades to the NaOCI storage tanks, pump and piping system will improve system reliability. Various improvements to other water quality control facilities (WQCF) are included in the project.   Expected Completion: TBD   Project Location(s):  Nancy Creek, Peachtree Creek, Proctor Creek, Sugar Creek, Cluster Basin   Council District(s):  2, 3, 5, 6, 7, 8, 9   Neighborhood Planning Unit(s):  A, B, D, E, F, G, H, K, M, O
