<br />Trunk Sewer Main Replacement, City of Escondido, CA. Principal -
<br />in -Charge. The City of Escondido's Trunk Sewer Main is a key piece of
<br />the City's sewer infrastructure system. The trunk sewer collects sewage
<br />from approximately 30% of the City and conveys it to the Hale Avenue
<br />Resource Recovery Facility (HARRF). The trunk sewer was constructed
<br />in 1959 and originally served as the outfall from the City's treatment
<br />facility to a lift station. However, when the HARRF was constructed, the
<br />pipeline was repurposed to serve as a trunk sewer in the City's collection
<br />system. In recent years, sections of the pipeline have been failing,
<br />requiring emergency repairs to keep this key piece of infrastructure
<br />in service. The original pipeline was constructed of 24-and 27-inch-
<br />diameter RCP; however, as emergency repairs were made, 30- and
<br />36-inch-diameter PVC were installed. This project replaces 5 segments
<br />of trunk sewer remaining from the original construction, which totals
<br />6,900 linear feet of trunk sewer.
