Devens Drive Water Line Replacement Project (Knox Valley Dr. to Wikle Rd. East)
The Water Services Department's water line replacement program is focused on incremental replacement of aging water lines in order to maintain the highest level of distribution service, reduce maintenance costs and avoid significant future capital infrastructure costs. The next area of water lines slated for replacement includes those located along Devens Drive, between Knox Valley Dr. and Wikle Rd. East. The project includes side streets: Lynhurst Ct., Glover Ct. (not Glover Dr.), Brentview Ct., Foxview Ct., Sherwood Green Ct. and Wikle Rd. East (the cul-de-sac east of Devens).
The route of the new water line will be generally along the path of the existing water lines, or on the east side of Devens Drive in the right-of-way. For cul-de-sacs, the line varies. If you are located along the route of construction, you can expect your driveway apron and possibly landscaping that is located in the right-of-way to be impacted. Any removal of the driveway apron or other material will be replaced with like material. The Devens Drive Water Project Map will show the affected areas where the new lines will be installed.
Project Status: The City has awarded a construction contract with JSJ Construction. Construction has begun (early October) and is anticipated to take approximately 7 months to complete. The work will take place along Deven's Drive along the south and east side of the road, following the existing water line route. The route in each Cul-de-sacs will vary.
Crockett Rd. and Deerwood Water System Improvement ProjectsThe Crockett Rd. water line replacement project proposes to replace existing water lines, service to homes and system appurtenances along Crockett Rd. between Raintree Blvd. roundabout to Ohara Drive. There will be some service lines replaced west of the roundabout but the larger construction activity will be between Raintree Blvd. and Ohara. This project also includes system improvements in the Deerwood neighborhood. These improvements include connecting the water line that serves Deerwood to the Johnson Chapel Rd. water line installed in 2014 and abandon the supply feed from the north that comes from Harpeth River Drive.
Project Status (Updated 10/17/19): Construction activity begin in July, 2019 along Crockett Road and all the 12 in water pipe has been installed. Crews are working on connections to side streets and services to customers. Work in Deerwood has just begun and is anticipated to take 4-5 week to complete.
Moores Lane Area Sewer Pressure Pipe Replacement Project
This projects proposes to replace an aging sewer pressure pipe from the intersection of South Carothers Pkwy. and Moore's Lane to near the entrance of the Nashville Golf and Athletic Club. The route will impact residents along Suzanne Dr., Rue De Grande and eastbound traffic along Moore's Lane.
Project Status: The City has awarded a construction contract to W&O Construction. Work has begun along Moore's Lane south right-of-way. Crews will be installing new pipe between Rue De Grande and Crockett Spgs. Tr. this fall and then move into the Suzanne Drive area towards the end of the year. Work is anticipated to take approximately 7 months to complete.
Water Loss Management Program
The goal of the WLMP is to reduce overall water loss or non-revenue water loss through implementation of a series of programs proven to be effective in decreasing water loss these will include the following areas:
The Department is contracting with a water system leak detection firm for pipe leak detection services. Leaks can be located underground via ultrasonic listening devices which can detect water escaping from leaks in pipes, pipe joints and valves. Work in the Spring of 2017 included leak detection of all pipes in the City's north pressure zone (generally north of the Little Harpeth River and Concord Rd). Work in FY 2018 will include leak detection and district monitoring in the rest of the service area.
Water Service Line Replacement
The Department is currently replacing water service lines (the section of smaller pipe between the public water main and the water meter) that meet specific age and material conditions that have proven to accelerate deterioration of the material. Many services have been replaced via an outside contractor in the Spring of 2017. In-house crews will be completing work annually as time permits.
Water Meter Reading System Upgrades and Data Analytics
The Department is currently upgrading the City's existing "walk by" meter reading system with an advanced, Sensus Flexnet reading system. The Flexnet system includes installation of multiple tower sites that read meters remotely as opposed to the more labor intensive, "walk by" reading system. The base infrastructure has been installed which included three tower sites which have been reading a small sample of meters for several years now. The Flexnet system works to provide the customer and department staff enhanced reading data (greater accuracy measurement of water moving through the meter) to increase operational efficiency and decrease operational costs as well as provide the customer with greater usage information which aides the customer in reducing water waste and potentially avoid costly plumbing repairs. City staff uses the enhanced metering data in capital project planning and customer support. For more information on the Sensus Flexnet system, visit the manufacturers site. For technical specifications related to the Flexnet transmitter module, they can be found in the Transmitter Specification page of the manufacturers website.
Project Status: The City has contracted with Baird Company to upgrade each customer's meter site with a new meter and/or transmitter based on the existing equipment at each site. This work began in March, 2019 and will continue into early 2020. As part of the contractor's scope, they are to knock on the homeowner's door prior to starting work, to communicate to the homeowner the need to shut off water for a short period of time (5-15 min) to allow for the work to be completed. Once the work is completed, the contractor will turn the water back on and open a spigot on the side of the home to flush water briefly if necessary to eliminate any air or mineral deposits stirred up during the process. Project notification are being sent out via social media, with updates sent to the neighborhoods where work is being completed.
