The result provides a more practical solution for pipeline networks that comprise the distribution systems within a utility’s service area. The use of V-Bio® enhanced polyethylene encasement in conjunction with metallized zinc provides water operators with an effective alternative to controlling corrosion in distribution systems. 3” to 24” 0 30” to 36” 8 42” to 48” 12 54” to 64” 22 Routine (Fair to good access, minimal traffic/other utility 0 consideration, etc.) Moderate (Typical business/ residential areas, some right 8 of way limitations, etc.) Difficult (Subaqueous crossings, downtown metropolitan business areas, 20 multiple utilities congestion, swamps, etc.) 0 to 10 feet depth 0 > 10 to 20 feet depth 3 > 20 feet depth 5 Alternate supply available - no 3 Alternate supply available - yes 0 TOTAL POSSIBLE POINTS PIPE SERVICE LOCATION: Construction-Repair Considerations DEPTH OF COVER CONSIDERATIONS ALTERNATE WATER SUPPLY POINTS 22 20 5 3 50 Consequence Score Sheet TABLE 3 The revised DDM® recognizes the practical differences in corrosion control needs between transmission mains and distribution systems.
