Work included placement of several large butterfly valves: 4 EA 72″, 2 EA 66″, 1 EA 60″, 3 EA 42″, and 2 EA 24″; placed within several vaults and control buildings. Eight areas were installed by method of trenchless crossings (under major highways and major intersections), while open cut areas required right of way improvements plus hydroseeding and landscaping restoration.
