Night Work Begins for the 16” Water Transmission Main and Pump Station Project

Date added: 23-Sep-2016 08:46 AM

Night Work Begins for the 16” Water Transmission Main and Pump Station ProjectOn Monday, March 2, 2015, Metro Water Services began the construction of a water main and water pumping station project with portions of work being adjacent to the Cleanwater Nashville OAP project, Lakewood Rehabilitation.

Starting May 31, 2015, night work will begin taking place for the construction of the water main portion of this project along Old Hickory Boulevard from 22nd to Hadley within the TDOT right of way. Due to traffic along Old Hickory Boulevard, TDOT restrictions require work to be completed from 7PM to 6AM. The work is expected to take approximately 2 months to complete.

2015 highlights include completion of major projects

Clean Water Nashville completed numerous projects in 2015 that upgraded Metro Nashville wastewater infrastructure.

DODSON CHAPEL PIPE IMPROVEMENTS PROJECT, located in Metro Council Districts 11 and 14, was completed in December 2015.

This project to upgrade system capacity included installation of approximately 3,280 linear feet of 48-inch and 30-inch diameter gravity sewer and 240 feet of 72-inch diameter casing that was placed under Old Hickory Boulevard.

The project reflects the careful planning required to update the system within a vibrant urban environment. In this case, replacing sewer underneath Old Hickory Boulevard meant conducting the work while maintaining traffic flow through the busy corridor. Project teams used jackhammers and other hand-held tools to dig a tunnel underneath Old Hickory. As digging out occurred, steel plate rings were installed to form a tunnel for the 48- inch diameter sewer pipe.
The Dodson Chapel Pipe Improvements Project is the second major Clean Water Nashville project completed in Hermitage. The Dodson Chapel Equalization Tank and Wastewater Pumping Station Expansion was completed in April 2014.

MILL CREEK/OPRYLAND EQUALIZATION FACILITY, PHASE II, increased storage capacity with the addition of a 19-million gallon, pre-stressed concrete wastewater storage tank adjacent to an existing 15-million gallon tank. The project was completed in April 2015.

Located in Metro Council District 19, the storage tanks are utilized when sewage flows exceed the capacity of the existing sewer system. The peak flows are stored until the flows in the system recede, and the stored volume can be conveyed through the system to treatment.

Expanding capacity of this facility will reduce sanitary sewer overflows.

COWAN RIVERSIDE REHABILITATION AREA 1—JONES AVENUE was conducted to renew aging infrastructure and to address downstream overflows by reducing the amount of rainfall that can enter the system through defects.

This project, located in an expansive area that includes Metro Council Districts 5 and 8, consisted of the evaluation of approximately 50,000 linear feet of gravity sewer, associated manholes and services laterals within Metro right-of-way and easements. The resulting construction project included the rehabilitation of approximately 40,000 linear feet of 8- to 15-inch diameter gravity sewer, 230 manholes and 630 service connections.
