The BRE score is a product <br />of the PoF times the CoF scores. This score is an informative indicator of facilities that will likely require <br />higher levels of attention; in the form of proactive replacement and /or targeted inspection monitoring. <br />It is typically based on a 1 to 100 scale metric. Figure B - 32 provides a distribution of Water Pipeline BRE <br />Scores. <br />Figure B- 32: Distribution of Water Pipeline BRE Scores <br />Figure B - 33 provides a "heat map' graph showing the resulting distribution of PoF vs. CoF scores by <br />miles of main. Combined, these represent the BRE score. Higher probability of failure assets are plotted <br />near the right. Higher consequences of failure assets are plotted near to the top. Figure B - 34 provides a <br />map of water mains color coded by total BRE score. A partial table of water main pipeline segments <br />ranked by BRE score is included in the Replacement Prioritization section below. <br />65B -132 <br />NOVEMBER 2014 <br />
