This design-build project was for the repair and replacement of failing sewer main in San Diego, CA. Orion immediately engaged with the City and determined that 1,900 LF of sewer main were suitable for trenchless (CIPP) replacement. This reduced construction impact on the area residents and businesses. Where CIPP methods were not suitable, Orion repaired by replacement of over 3,300 LF of sewer main. Finally, Orion installed by open-cut methods over 1,600 LF of sewer main.
