In the Spring of 2009, Innerline Engineering was contracted to inspect all of the sewer lines at the MWD desert pump plants. These pump plants were constructed in the 1930’s in order to convey water from the Colorado River to Southern California.
Inspecting aging sewer infrastructures at Whitsett Intake Pump Plant, Gene Pump Plant, Iron Mountain Pump Plant, Eagle Mountain Pump Plant and Julian Hines Pump Plant proved to be a challenge. With a large percentage of sewer pipe of only 4 inch in diameter, push rod systems were required in order to complete the inspection process.
