1 Plans and Goals for 2016 Board Members Employees

2 Calleguas MWD Water wholesaler 630,000 people 19 member purveyors???? AF/year annual demand

3 Historical Deliveries on pace to sell 76,000 AF this year

4 Mission Statement Provide the service area with a reliable supplemental supply of regional and locally developed water in an environmentally and economically responsible manner.

5 State Water Project Lake Oroville Sacramento & Feather Rivers Northern Sierra Bay- Delta 5 Quail Lake San Luis Reservoir Pyramid Lake West Branch Castaic Lake 5

6 Castaic Lake Jensen Filtration Plant Santa Susana Tunnel

7 Calleguas Purveyors

8 Percentage of water supply which is imported Moorpark Oxnard Port Hueneme Camarillo ~50% ~99% Thousand Oaks Simi Valley

9 Our challenges

10 1. Imported supplies are becoming less reliable Fish Protections Restricting SWP Flows Colorado River System Oversubscribed Climate Change Reducing Snowpack Population Increasing

11 2. Imported supplies are vulnerable to seismic activity Calleguas Service Area So. Calif. Earthquake Center (SCEC) 0 1/ >5 Number of times per century the shaking from earthquakes will exceed 20% of the force of gravity. Significant damage to older buildings will begin at this level.

12 3. Calleguas local supplies (for use during outages) have constraints LIMITED LAKE VOLUME FOR LONG OUTAGES LIMITED PUMPING CAPACITY FOR LONG OUTAGES Lake Bard Las Posas Wellfield

13 Plans for 2016 Improve Water Supply Reliability Las Posas ASR Project Salinity Management Pipeline & Purveyor Desalters Interconnections Planning for the future

14 Las Posas Aquifer Storage and Recovery Project

15

16 Aquifer Storage and Recovery (ASR) Imported Water ASR Wells to customers

17 Las Posas ASR Project Existing Facilities Los Angeles Ave.

18 Grandsen Pump Station Phase 2 construction to begin in early 2016

19 East/South Las Posas Aquifer Water Level Monitoring Purpose: Quantify impact of Calleguas ASR on neighboring pumpers Provide field data to support basin modeling Probes monitor water levels continuously In 2016 easements will be acquired for additional Calleguasowned wells

20 East/South Las Posas Aquifer Modeling Purpose: improve understanding of effects of Calleguas ASR on neighboring wells long term storage & production capacity Conceptual model nearly complete Numerical model to be completed in 2016 Preliminary Draft

21 Las Posas Users Group Participation Calleguas Goal: achieve sustainable basin management without conflict 2016 Activities Work with pumpers to begin to implement an allocation proposal (subject to GMA approval) Participate in GMA s stakeholder process to develop a Sustainable Groundwater Management Plan Complete a supplemental water supply alternatives analysis

22 Salinity Management Pipeline (SMP) and Purveyor Desalters

23 By providing a means of transporting salts to the ocean, the SMP Increases water reliability by allowing brackish groundwater to be put to use Reduces salinity in the aquifers by removing salt from the watershed Somis Moorpark Simi Valley Camarillo Thousand Oaks Oxnard Port Hueneme

24 Who wants to build a desalter? Municipal Agencies Cheaper than imported water Diverse supplies improve reliability Agriculture More expensive than current sources, but Aquifers getting more saline Choices are limited

25 Status of SMP Construction Camarillo Somis Moorpark Simi Valley 2022 Oxnard Thousand Oaks Port Hueneme Complete

42 Interconnections

43 Interconnections for Supply Outages Crestview MWC Las Virgenes MWD

44 Interconnections to Facilitate Desalters Calleguas pipes Purveyor turnouts Proposed desalter Camarillo

45 Planning for future reliability

46 Seawater Desalination Feasibility Study (complete) Pros Large volume for outages of imported water Drought proof Cons Permitting challenges Cost plant, connection pipes, ocean construction

47 Task for 2016: Evaluate what supply option(s) could meet our service area s reliability needs in the most cost effective and environmentally responsible manner Storm water Capture Partnerships Storage in Another Agency s Lake
