Ruidoso High School Sewer Line Repair and Replacement Project

The sewer line in need of replacement is currently four inch cast iron located underneath the hallway immediately inside the main entrance to the high school . The sewer line is estimated to be approximately 24 to 36 inches in depth below the building’s concrete slab. The District has camera video of issues in line with approximate locations. The issues on video appear to show deterioration and multiple “sags” in line causing it to hold effluent. The thickness of the slab was determined by 3 core holes along the line to be approximately 8 inches thick. There are as many as six tributary lines entering the four -inch sewer line. The tributary lines vary in size from two to four inches. The sewer line failures cover approximately 120 linear feet.
