JULY 2018

Water Supply Program: Quarry/Chattahoochee/Hemphill Update: The tunnel boring machine (TBM) has mined approximately 17,169 feet. On average, the TBM mines approximately 60 feet per day. Excavation and rebuilding of an existing pump station is still underway at the R.M. Clayton Water Reclamation Center, located at 2440 Bolton Road NW. Controlled blasting is necessary to complete the construction shaft and a short tunnel connecting the shaft to a proposed Chattahoochee River Intake pump station. During this phase, controlled blasting must take place to complete the shaft and the short tunnel for the pump station. Blasts are anticipated to begin in the month of July and will continue through January 2019.   In addition, crews are currently working on a power tie-in at the Hemphill Water Treatment Plant. Construction of two new pump stations continues and crews will continue to install the roof on the pump station located at the Quarry.  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: 9/2019 Project Location: Northwest Atlanta Council District(s): 3, 9 Neighborhood Planning Unit(s): C, D, G, J, K

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

Update : Contractors removed the last stock pile of dirt for the main remediation and pipe installation is set to begin.  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 street in the Vine City area and remediating and relocating sewers.  Expected Completion: 11/2018 Project Location: Northwest Atlanta Council District(s): 3 Neighborhood Planning Unit(s): C, D, E, G, H, I, J, K, L, M T

R.M. Clayton Sand Filter Media Installation and Refurbishment Project

Update:  A certificate of substantial completion was established May 18. A detailed punch list was generated for contractors on June 4 with all items to be addressed by July 27. All 22 filters are in active operation with final acceptance upon completion of the punch list is anticipated no later than August 5. The R.M. Clayton WRC treatment process removes biological and chemical impurities from the wastewater in three phases: primary treatment, secondary treatment and tertiary treatment. Primary sludge and biological solids that are removed during the wastewater treatment process are reduced in the digestion process before being dewatered and incinerated or hauled to a landfill. This project will restore the effectiveness of the filtration process, reduce the backwash frequency and duration, reduce the maintenance costs and improve overall plant reliability in meeting permit limits. The project is estimated to be completed in June 2018.   Expected Completion: 8/2018 Project Location: R. M. Clayton Water Reclamation Center Council District(s): 9 Neighborhood Planning Unit(s): D

Boone Boulevard Green Infrastructure & Capacity Relief Project

Update: Water mains are tentatively scheduled to be replaced in the third quarter of 2018 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. Now under the project, DWM will replace water mains on Joseph E. Boone Boulevard NW between Northside Drive NW and Mayson Turner Road NW.  Expected Completion: TBD Project Location: Northwest Atlanta Council District(s): 3 Neighborhood Planning Unit(s): K, L, M

Clear Creek West Sewer Improvements Project

Update : Contractors are working on the construction of the bypass channel’s foundation slab, wall and roof slab of the vault. In addition, contractors are preparing the bypass of a 10 feet x 8 feet egg-shaped brick sewer and 78 inch reinforced concrete pipe (RCP) sewer trunks to allow the construction of the remaining part of bypass channel to be completed. Construction is at 61% completion.  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 the Butler Street Trunk Combined Sewer 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: 7/2018 (Design Phase) Project Location: Northeast Atlanta Council District(s): 2 Neighborhood Planning Unit(s): M, E

Clear Creek Combined Sewage Control Facility Package 1, Chemical System Improvements and Flow Monitoring

Update : The Demo FE2801 West Area transit time flow meter and the FE2901-1 level meter has been installed.  An instrument bridge installed at Custer Ave. The water meter will allow DWM to measure the Intrenchment Creek Channel, improve the ability to measure the water flow will result in more accurate control decisions regarding water treatment, allow DWM to gain a more accurate control decisions regarding water treatment will result in better quality water for the neighborhood. A Video of the installation can be found here: https://youtu.be/SJyy2Bwiuso. A new manhole will be installed in front of the Grady High School entrance located off 10th Street, NE. This manhole is being installed to measure and monitor flow from the Butler Highland Trunk to Clear Creek Combined Sewage Control Facility (CSCF). A flow meter will be installed in the manhole which will measure and monitor the flow through the trunk sewer for better treatment. This work is a State of Georgia EPD requirement.   A flow signal antenna will be 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: 3/2019 Council District(s): 2, 3, 5, 6, 7, 8, 9 Neighborhood Planning Unit(s): A, B, D, E, F, G, H, K, M, O

Niskey Lake Environmental Restoration

Update : This project is on hold. This project is necessary to remove approximately 209 cubic yards of sediment from the upstream/ western embayment of Niskey Lake that was caused by the failure of the Niskey Lake Trail when the upstream beaver dam failed and when insufficient erosion control measures and good housekeeping practices during the reconstruction of Niskey Lake Trail allowed eroded soils and stockpiled construction materials to wash into Niskey Lake in 2014.  The implementation of this contract is necessary to achieve the following goals:  Eliminate the sedimentation that occurred when the upstream beaver dam failed, causing a wave of water to wash out the road.  Project Location: Niskey Lake - Southwest of I-285 & I-20 Interchange Council District(s): 11  Neighborhood Planning Unit(s): K
