SEPTEMBER 2018

Water Supply Program Quarry/Chattahoochee/Hemphill

Update: Mining approximately 21,120 feet underground, the 400-foot-long tunnel boring machine (TBM) known as “Driller Mike” has reached a significant four-mile milestone.  DWM will continue with the excavation and lining of a 2000-foot long tunnel that will connect the Chattahoochee construction shaft to a proposed River Intake Pump Station shaft near the R.M. Clayton Water Reclamation Center, located at 2440 Bolton Road NW. During this phase, controlled blasting must take place to excavate the connecting tunnel to the proposed River Intake pump station. Construction of two new pump stations continues at the Bellwood Quarry and the Hemphill Water Treatment Plant sites.  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(s): 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: The project is currently ongoing, and the construction phase has resumed. 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(s): 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: Replacement of the sewer line from Walnut to Thurmond Street is 57 percent complete. The project is designed to help alleviate flooding while providing increased greenspace in Vine City. The project consists of installing a new capacity relief storage facility in the area, installing 2,200 linear feet of 60-inch capacity relief trunk line, re-routing 1,100 LF of 96-inch combined trunk sewer by installing pipeline in the right-of-way along streets in the Vine City area and re-mediating and relocating sewers.  Expected Completion: November 2018 Project Location(s): Vine Street NW, Atlanta Council District(s): 3 Neighborhood Planning Unit(s): C, D, E, G, H, I, J, K, L, M T

Boone Boulevard Green Infrastructure & Capacity Relief Project

Update:  Water main replacement work is scheduled to resume in September on Joseph E. Boone Boulevard NW between Northside Drive NW and Mayson Turner Road NW. Stormwater planter boxes, sidewalks, driveway aprons and tree installations have been completed along the southern side of Joseph E. Boone Boulevard NW between Joseph E. Lowery Boulevard NW and Sunset Avenue NW.  Expected Completion: June 2019 Project Location: Northwest Atlanta Council District(s): 3 Neighborhood Planning Unit(s): K, L, M

Clear Creek Combined Sewage Control Facility

Update: Refurbishment of three storage tanks at Clear Creek Combined Sewage Control Facility (CSCF) are complete and the fourth is expected. Phase one which is the installation of a new chemical feed piping at the CSCF, is complete and operational. The installation of the manhole and a flow meter at the Tanyard (CSCF) has been completed and the drum screen at Custer Avenue CSCF has also been rebuilt. This project is approximately 82 percent complete. Installation of the new manhole and flow meter in front of the Grady High School entrance located off 10th Street, NE. is complete. This manhole will measure and monitor flow from the Butler Highland Trunk to Clear Creek Combined Sewage Control Facility (CSCF). This work is a State of Georgia EPD requirement. A flow signal antenna was installed in Piedmont Park between the Dog Park and the Meadow. This antenna will help the City of Atlanta get an accurate understanding of discharge volume to the Clear Creek Combined Sewage Control Facility (CSCF) and allow for better treatment.   Expected Completion:  September 2018   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

Energy Services Performance Initiatives Noresco/Schneider

Update: Majority of lighting work has been completed at both Hemphill Water Treatment Plant and Chattahoochee Water Treatment Plant. Contractors are completing leak repairs at Utoy Creek Administration Building. Contractors have begun mobilizing for lighting upgrades at the 14th Street Administration Building Complex. Facilities infrastructure improvements for RM Clayton Water Reclamation Center (WRC), Hemphill water distribution system, South River WRC, Utoy Creek WRC, Chattahoochee Water Treatment and 14th Street Administration Complex. Expected Completion: December 2020 Project Location(s): R.M. Clayton WRC, Hemphill WTP (Settled Solids only), South River WRC, Utoy Creek WRC, Chattahoochee Water Treatment, and 14th St Admin Complex Council District(s): 1, 3, 8, 9, 10 Neighborhood Planning Unit(s): C,D,E,G,H,Z

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. The City of Atlanta modeling group proposed upsizing the outfall to provide capacity relief and reduce the surcharge in the existing trunk line. The project includes upsizing the existing line by excavating down to, and exposing the existing pipe in an open cut trench so that the pipe can be repaired or replaced. The trench is then backfilled to close it. The existing line is west of the CSX railroad where the fallout discharges into the Proctor Creek Trunk. Expected Completion: November 2018 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 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. Expected Completion: September 2019 Project Locations(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

Neighborhood Planning Unit (NPU) The City of Atlanta is divided into 25 Neighborhood Planning Units (NPU), which serve as citizen advisory councils that make recommendations to the Mayor and City Council on zoning, land use, and other planning issues. NPUs also allow citizens to receive information about all functions of city government.
