Managing the Risks Presented by Pipeburst, Redundant and Live Asbestos Cement Pipe Water Distribution Mains: Estimation of the Costs Associated with Different Rehabilitation Techniques
The objective of this study was to estimate the relative costs of each rehabilitation option in order that all acceptable options (with respect to risk) can be compared financially.
Standard Ofwat costs (benchmark and mid point) were used to determine the relative costs of five rehabilitation techniques. These costs were for all materials, consequently, additional costs specific to asbestos cement pipes were identified and listed.
The costs given are the lowest value due to the nature of the Ofwat costs, and are likely to underestimate the true costs. Conclusions and recommendations are also made.
