24-inch Water Transmission Main Across the Tennessee River

Problem

In order to provide emergency water service for several vital industries in Loudon, Tennessee, a 24-inch waterline needed to be installed across the Tennessee River to complete the connection. The riverbed was primarily bedrock which would require blasting, several railroad and highways needed to be crossed using bores, and many existing utilities would need to be avoided during the installation.

Solution

CTI revised an existing design for the project and obtained updated permits from numerous regulatory agencies for the project. The river crossing required large concrete anchors on the pipe every 20 feet and needed to be installed at a specific elevation for the entire length of the crossing to meet the US Army Corps of Engineers navigational requirements.
