Wastewater Infrastructure Project in Marathon, Texas

Status: Completed


Portions of the existing wastewater collection system were constructed nearly 50 years ago using 6- and 8-inch vitrified clay pipes that no longer have sufficient cover to protect the integrity of the pipe. The utility has been experiencing chronic issues with line breaks and sewage spills due to the age and deterioration of the pipes. In some cases, the raw sewage has backed up into homes and businesses, exposing the public to serious health risks. The most acute problems are occurring in the segment of the main trunk line that runs from the First Street alleyway to the Marathon Wastewater Treatment Plant (WWTP).

Project Scope

The project consists of replacing approximately 8,800 ft of the sewer main from the First Street alleyway to the Marathon WWTP, reconnecting 46 existing service connections to the new trunk line, installing approximately 3,700 ft of new laterals along southeast Sixth Street, Anderson Street and southwest Seventh Street to connect nine residences to the sewer system and decommissioning of nine septic systems and a lift station.


The project will prevent wastewater spills and sewage backups due to line breaks, thus helping reduce water pollution and the risks of waterborne diseases. It will also provide first-time access to wastewater services for nine households in unserved areas, which will collect an additional 2,000 gallons per day of wastewater for treatment.
