MARCH 2019

Water Supply Program Quarry/Chattahoochee/Hemphill

Update: Post mining activities are underway . Crews will continue to clean and line the interior of the tunnel with concrete liner. Approximately 1,800 feet of the lining is complete.  Controlled blasting at the R.M. Clayton Water Reclamation Center will continue. In addition, the construction of the Quarry and Hemphill pump station are still in progress. 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

Hartsfield-Jackson Manifold Improvements Project

Update: Slab has been poured at our pump station at Hartsfield-Jackson Airport. Contractors will begin laying pipe in March.   This project reinforces the integrity of services for which the Hartsfield-Jackson Water Distribution Facility were constructed. Doing so will ensure availability of uninterrupted quantity and quality of water distribution to the airport. Expected Completion: June 2019 Project Location: South Loop Road, Hartsfield-Jackson Atlanta International Airport Council Districts: 11, 12 Neighborhood Planning Units: P, Q, R, Z

Clear Creek West Sewer Improvements Project Civic Center Vault

Update: Crews will continue to pour the walls and elevated decks. Crews will also tie- in rebar, strip the top deck, pour columns, slabs and forms. The City of Atlanta 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 former 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 two-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 which is responsible for the build-out of the adjacent park. In addition, The National Monuments Foundation will be construct and install statues of historic figures throughout the finished park.   Expected Completion: July 2019 Project Location: Vine Street NW Council District(s): 3 Neighborhood Planning Unit(s): L

Upper Proctor Creek - Boone Boulevard Green Infrastructure & Capacity Relief Project

Update: Contractors will continue with the replacement and installation of water main pipe and planter boxes down Boone Boulevard towards Northside Drive.   This project will provide capacity relief to the North Avenue Combined Sewer Area and water quality improvements using the green infrastructure practice called bioretention, which is a specially landscaped area that captures runoff from an impervious surface and allows water to enter the soil. Proposed bioretention areas will span approximately 1.2 miles along Boone Blvd from Mayson Turner Road to Northside Drive that will collect stormwater runoff from along the sides of the road. Expected Completion: June 2019 Project Location: Northwest Atlanta Council District(s): 3 Neighborhood Planning Unit(s): L

Energy Services Performance Initiatives - Noresco

Update: UV System replacement work will begin at RM Clayton. Also, contractors will be working on grade beams, pilasters and wall forms over the next few weeks and will begin under-slab utilities in March. Contractors are working with OLIO to install seven key pressure sensors to collect data for the Aquadvanced® Energy (AEE) Software. The AEE software will help the Department of Watershed Management optimize pump station operations to reduce energy consumption.   Three Energy Conservation Measures (ECM) for a software system to optimize the City's water distribution system are being implemented: a new Class A bio-solids system, office space at RMC WRC, and a replacement of ultraviolet disinfection system with new Trojan UV Signa System.

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
