38th Avenue Water Storage Tank Design

Connico provided cost estimating for the project that consisted of the replacement of an existing 3-million-gallon (MG) water storage tank with a new 2.5 MG cylindrical precast concrete water storage tank. The original tank was constructed in 1945 out of reinforced concrete and was partially buried between 37th and 38th Avenue North in Nashville, Tennessee due to age, condition, and turnover issues. This project was for the Metro Water Services for the Government of Nashville and Davidson County.

The existing tank cuts across a hillside where the lower portion (38th Avenue side) is exposed. The north, south and east sides of the tank were completely below ground. The top of the tank was covered with approximately one foot of earth backfill and sod. The exposed side of the tank has a stone façade that Metro Water Service requested to be preserved and incorporated in the tank replacement project.

The project included elements such as: removal of the existing water tank roof, columns, walls, water line, drain line, and tank; 24-foot-tall retaining wall onsite improvements; installation of 2.5 MG prestressed concrete tank; water tank exterior architectural artwork finishes; tank ventilators; pressure sensors/switches; general electrical work; pavement; and excavation and backfill.
