To Become an Asset Management Based Organization You Need To Address 1. Customer and environmental service levels 2. Risk assessment and quantification 3. Life Cycle costs analysis using triple bottom line 4. Long Range Planning 5. Asset and data systems 6. Rational Rates and Affordability 7. Clarity of Organizational Roles and Responsibilities 8. Formal Capital Decision Making Processes 9. Track and Measure Results 10. Benchmarking Customer Service Levels and Performance Indicators l Find out from customers what services are most important to them l Set service levels and make investments needed to meet them-now and into the future l Establish and measure performance indicators Wastewater Service Levels Category Category Service Level Service Level Performance Indicators Performance Indicators Effective Effective Conveyance Conveyance (SSO sewer (SSO sewer backups) backups) By 2020, no more than one By 2020, no more than one sewer backup in 5 years, on sewer backup in 5 years, on average, at any location, average, at any location, caused by a problem with the caused by a problem with the SPU sewer system.

No performance measure. Awareness Campaign Messaging; no incentives. Less intense than 1% program. Customer survey to assess effectiveness. Results estimated <.3 MGD annual savings. Program to Shave Peak Investment Variable Less intense than 1% program. Set performance goal for peak season. Results could range from <.3 5 MGD peak season savings. Low Intensity Program / Investment Less intense than 1% program. Set performance goal on per capita demand. Results could be in range of .7 MGD annual savings. Medium Intensity Program / Investment Similar intensity to 1% program. Set performance goal to keep demand flat. Results could range from 1-1.5 MGD annual savings. High Intensity Program / Investment Intensity estimated to be greater than 1% program. Set performance goal to reduce total demand. Results could be above 1.5 MGD annual savings.
