Proactive Sewer Rehab Program Gets Great Results

In 2014, SAWS crews and contractors cleaned more than 1,800 miles of pipe across the city, reducing the number of sewer spills by almost half since 2012.

imageAs part of the 2013 settlement with the U.S. Environmental Protection Agency, SAWS crews have accelerated their work televising, cleaning and repairing sewers across San Antonio.

Line cleaning crews use remote-controlled robots to pressure wash each section of sewer main. This ensures debris, grease and roots are proactively cleared on a regular basis, reducing the number of emergency responses.

Televising crews use robotic cameras to inspect pipes so problems can be corrected before a spill occurs. While grease continues to be a major source of back-ups, statistics show that wipes and structural failures are actually larger problems.

When an overflow is caused by a structural failure, a point repair crew is dispatched to fix the problem to avoid a repeat overflow. These crews sometimes replace an entire section of sewer main, manhole to manhole, such as when the crown of the pipe has caved in.

In addition, SmartCovers, remote alarm systems which are installed on select manholes, helped prevent 500 potential spills in 2014.
