The Trinity River Job

An 18 inch city sewer main line running directly beneath the Trinity River was breached, allowing sewer waste to discharge into the Trinity River. Under strict scrutiny from the Trinity River Authority, Accurate Leak & Line successfully lined the broken pipe beneath the river with an 18 inch cast-in-place epoxy pipeliner (CIPP). The trenchless sewer repair saved millions in costs in damning the river to make traditional repairs.

Pump trucks were utilized to bypass the section of line beneath the river from manhole to manhole, allowing Accurate to install liner during peak use hours. Gas generators and compressors provided power and air to the remote work site. A robot video camera line pipe inspection was performed following the removal of the bladder. The inspection concluded a successful rehabilitation of the inaccessible, breached sewer main.
