~99%~50%

Percentage of water supply which is imported

Our challenges…

1. Imported supplies are becoming less reliable

Colorado River System OversubscribedFish Protections Restricting SWP Flows

Climate Change Reducing Snowpack Population Increasing

2. Imported supplies are vulnerable to seismic activity

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.

Las Posas ASR Project Existing Facilities

Los Angeles Ave.

Grandsen Pump Station Phase 2 construction to begin in early 2016

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 Calleguas‐owned wells

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

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

Increases water reliability by allowing brackish groundwater to be put to useReduces salinity in the aquifers by removing salt from the watershed

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

• Large volume for outages of imported water• Drought proof

• Cons• Permitting challenges• Cost – plant, connection pipes, ocean construction

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
