Review of Water Mains Serviceability Indicators and Condition Grading: Volume II - Mains Condition Grading
This report presents the results of a review of existing and potential approaches to condition grading of water mains. The work carried out involved a review of current practice by Water Companies and other utility industries, consultation with UK water industry regulators and trials and subsequent analysis of a proposed revised approach.
A number of recommendations are made including the adoption of observed burst rate as the single basis for mains condition grade. An approach to calculating burst rate based on the formulation of mains cohorts is proposed. Examples of the application of the proposed approach are provided.
