At recent rates (2011), when will cast iron pipe be completely replaced?

At the current rate of replacement, we are losing the battle

Age Distribution of Infrastructure

More Strategic, and Cost Effective Tactics

• Better tools to prioritize replacement are being

used and developed

– Equipment to better assess and monitor pipes and the environment (e.g., smart pigs); – Better tools to locate and quantify leaks (e.g., EDF/CSU/Google).

• Predictive tools that facilitate greater proactivity,

leak avoidance and replacement planning

– Determining rate of degradation of pipe segments (especially after an initial repair), and the expected rate of increase in emissions

• Result – Better planning and cost effective

response; Share the data

Local Distribution Methane Mapping

From its early results, EDF is finding leaks that the local utilities had not. A few have been significant enough that they were immediately repaired.

Replacement and Leaks Performance Standards

• Service quality reporting should entail leaks

per mile (for type of pipe), and gage cost effectiveness

• Incentive based ratemaking – considering

predictive data with replacement targets

• LUAF – performance standards for LUAF

considering replacement targets

– Refine the correlation between leaks and LUAF
