Planning, Replacing, Rehabilitating, and Tunneling Aging Sanitary Sewers in Temple, Texas

The Bird Creek Interceptor is one of the primary wastewater gravity pipelines serving the City of Temple (City). Built over 60 years ago, this 5.3-mi portion of the interceptor constructed of vitrified clay and brick manholes has experienced numerous overflows in recent years due to excessive infiltration/inflow (I/I), lack of capacity, and aging conditions. The interceptor passes through private property, public parks and golf courses, crosses TXDOT infrastructure and BASF rail lines, and is lain within easements and right-of-way. Carter Burgess, contracted in 2007 to assist the City of Temple to identify sanitary sewer overflows (SSOs), underwent an effort to evaluate the system, flow monitor, and prepare a hydraulic model to identify the exact problems that exist within the interceptor and recommend improvements necessary to properly convey the peak wastewater flows to the Brazos River Authority (BRA) Temple-Belton Regional Sanitary Sewer (TBRSS) Lift Station.
