Level Of Service_presented atTennessee Association of Utility Districts Nov09

  1. 3. LOS DEFINITION <ul><li>Level of service (LOS) : LOS represents a service vs cost assessment. So establishing an LOS is equivalent to establishing an understanding of service vs cost for one or more levels of service. </li></ul>
  2. 4. WORKSHOP ASSIGNMENT <ul><li>Break into groups of 8-10 </li></ul><ul><li>Decide if group wants Water or Sewer focus </li></ul><ul><li>Determine 3 Categories for LOS (e.g. water quality, redundancy, pressure) </li></ul><ul><li>For each Category, determine 3 different levels of service, and the key cost factors </li></ul><ul><li>Identify how you could get customer input </li></ul>
  3. 5. LOS Tool Example <ul><li>Some of the tools used in establishing LOS based on water quality are a taste/odor chart, for example, such as the following slide </li></ul>
  4. 6. Example Water LOS Categories <ul><li>Quality </li></ul><ul><ul><li>Taste </li></ul></ul><ul><ul><li>Smell </li></ul></ul><ul><ul><li>Hardness </li></ul></ul><ul><ul><li>Color </li></ul></ul><ul><li>Availability/Redundancy (generators, looping/backfeeds, #customers out of service, etc) </li></ul><ul><li>Criticality/Reliability </li></ul><ul><ul><li>SDWA Compliance </li></ul></ul><ul><ul><li>Critical assets in service: hospitals,schools, transmission </li></ul></ul><ul><li>Pressure (too much, not enough, irregular?) </li></ul><ul><li>% losses (assume this is paid by customers) </li></ul><ul><li>Capacity and/or Fire Flow </li></ul>
  5. 7. Determining LOS <ul><li>Example LOS Criteria for Taste Quality </li></ul>
  6. 9. Example LOS Criteria <ul><li>Reliability </li></ul><ul><ul><li>SDWA compliance - % of users impacted annually </li></ul></ul><ul><ul><li>Impact to critical assets </li></ul></ul><ul><ul><li>Maximum/Avg # users impacted per break </li></ul></ul><ul><ul><li>May include redundancy – generators, etc </li></ul></ul>
  7. 10. Example Variations in LOS <ul><li>Reliability Goal: </li></ul><ul><li>Max 25 customers out of service for any one break </li></ul><ul><li>Cost Implication: </li></ul><ul><li>Need more valves? </li></ul><ul><li>Need “parallel” transmission main(s)? Or storage at opposite end from supply? </li></ul>
  8. 11. Example Sewer LOS Categories <ul><li>Quality (Effluent compliance with EPA standards, or any community desire for cleaner) </li></ul><ul><li>Redundancy (generators for plant, pump/lift stations, internal plant redundancy during repairs, etc) </li></ul><ul><li>Odor (at pump stations, plants, or other problem locations) </li></ul><ul><li>Reliability/Maintenance (frequency of back-ups, overflows, etc) </li></ul><ul><li>Improvements to reduce O/M costs passed on to users (energy, I/I treatment costs, etc) </li></ul><ul><li>Capacity </li></ul>
  9. 12. WORKSHOP ASSIGNMENT <ul><li>Break into groups of 8-10 </li></ul><ul><li>Decide if group wants Water or Sewer focus </li></ul><ul><li>Determine 3 Categories for LOS (e.g. water quality, redundancy, pressure) </li></ul><ul><li>For each Category, determine 3 different levels of service, and the key cost factors </li></ul><ul><li>Identify how you could get customer input </li></ul>
