Pasadena Water and Power 13 Water IRP and UWMP Integrated Resource Plan (IRP)  Update water demand forecast  Identify potential water supply and conservation alternatives to meet demand  Establish portfolio objectives  Determine ideal mix supply and conservation Urban Water Management Plan (UWMP)  State-required form of documentation (report)  Includes IRP elements  Specifically addresses BMP implementation

14. Pasadena Water and Power 14 Impacted Supply & Demand Restricted Imports and Local Supply

15. Pasadena Water and Power 15 Water Conservation Goals Highlighted Goals: Urban Accords – 10% by 2015 Urban Accords – 10% by 2015 California – 20% by 2020 California – 20% by 2020

16. Pasadena Water and Power 16 Supply Uncertainties Remain Import Constraints  Delta imports in flux  Future of drought?  MWD curtailments beyond FY 2010  Additional imports available at “penalty rate” Demand Reduction from Recycled Water and Conservation Programs (?) Regardless of Recent Rain, Supply Issues Will Persist

17. Pasadena Water and Power 17 Water Conservation Plan Update Nancy Long

18. Pasadena Water and Power 18 Comprehensive Water Conservation Plan Approved by Council April 13, 2009 New Conservation Emphasis:  Using price signals in rate design to encourage conservation  Increased outdoor water efficiency  Maximizing new construction efficiencies

19. Pasadena Water and Power 19 Six Conservation Approaches 1. Conservation Rate Design 2. Sustainable Water Supply Ordinances 3. Incentives for Water Efficient Technology and Practices 4. Direct Installation and Distribution 5. Audits 6. Information, Education and Outreach “PWP Water Conservation Effort is Not Business As Usual”

20. Pasadena Water and Power 20 Conservation Approach 1: Conservation Rate Design Step 1 (to be completed by July 1, 2009)  Propose revenue increase to maintain fund health  Propose modifications to existing block rate structure  Propose drought surcharge and allocation scheme  Complete classification of water customers  Improve water usage data on bills Step 2 (complete within 18 months)  Propose additional revenue increase  Evaluate effectiveness of Step 1 initiatives  Develop budget-based rate proposal (by Dec. 2009)  Propose water Public Benefits Charge  If allowable under Proposition 218  Implement budget-based rate and PBC (by July 1, 2010)

21. Pasadena Water and Power 21 Conservation Approach 1: Proposed Rate Design Tiered Rates Sized According To Usage within Each Meter Size Class  Block 1: 0 to 35% of average use  Block 2: 35% - 80%  Block 3: 80% - 90%  Block 4: 90% - 95%  Block 5: >95%

22. Pasadena Water and Power 22 Conservation Approach 2: Water Supply Ordinances Adopt Ordinances:  Permanent Water Waste Prohibition: June 1  Modified Water Shortage Plan: June 1  State Model Landscape Ordinance: Nov. 2009 Review/Update City Codes/Requirements:  Graywater & rainwater review: June 2009  Fixture replacement on resale: Summer 2009  New development requirements  Construction standards/building codes

23. Pasadena Water and Power 23 New Permanent Water Waste Prohibitions No Watering Between 9 a.m. and 6 p.m. (hand watering and system repairs allowed) No Watering During Periods of Rain No Excessive Water Flow, Runoff, or Washing of Hard Surfaces Obligation to Fix Leaks Restaurants Required to Use Water Conserving Dish Wash Spray Valves Recirculation Systems Required for Fountains, Car Washes, Commercial Laundry

24. Pasadena Water and Power 24 Water Waste Prohibitions: Key Exemptions Water to Protect Public Health and Safety Recycled Water, Gray Water, and Rainwater Use by Commercial Nurseries and Growers Hand Watering of Trees, Shrubs and Vegetation Intended for Consumption Landscape for Fire Protection and Erosion Control Rare Vegetation or Essential to Protected Species Public Parks, Playing Fields, School Grounds, Golf Course Green And Day Care Centers – Allowed to Water at Least Two Days Per Week

25. Pasadena Water and Power 25 Water Shortage Plan Reduce Consumption During Supply Shortages ( Drought or Supply Limitations ) Council Public Hearing to Determine:  Water Shortage Exits  Water Conservation Target ( 10%, 20%, etc. )  Shortage Plan Level 1, 2, 3, or 4 Determination Takes Effect Immediately

26. Pasadena Water and Power 26 Water Shortage Plan Levels Level1234 Watering Days Per Week 3 Summer 1 Winter 2 Summer 1 Winter 1 Summer 1 Winter No Irrigation Obligation to Fix Leaks, Breaks or Malfunctions 72 hours after notification 48 hours after notification 36 hours after notification 24 hours after notification Additional Limitations/ Prohibitions N/A Filling ornamental lakes or ponds; washing vehicles Filling residential pools/spas; no new potable water service

27. Pasadena Water and Power 27 Conservation Approaches 3-6 Approach 3 & 4) Incentives & Direct Install  Target high consumption, low efficiency uses  Target outdoor: Initiate turf replacement incentive when funding becomes available from State  Distribution of water efficient devices  Provide incentives in partnership with MWD Approach 5) Large User Audits  56 of 150 commercial sites as of May 31 2009  Target multi-family & large residential in Phase II (thru June 2010) Approach 6) Education & Outreach  Publications, workshops, demonstration sites, online tools  Recognition

28. Pasadena Water and Power 28 20% Conservation “Targets” “Growth Mitigation” includes building standards, new development offsets, ordinances (e.g., ROR) Indoor/Outdoor Use reductions from combination of cash incentives, landscape ordinance, audits, education, etc.
