Overview of Water Issues

Other Imported Water IssuesSource Water QualityMWD Water Costs

• In 2009, full service water rates increased 15% (3 times the previousyear’s increase)

• Over next five years, MWD expects annual double-digit rate increases

• Bay-Delta solution is expected to costbillions for MWD alone

Climate Change

• California DWR estimates that future climate change could reduce SWP supplies statewide by as much as 15% by 2030

IRP Definition“Comprehensive approach to evaluating supply-side & demand-side resource alternatives with respect to explicitly defined & often conflicting objectives.” AWWA, 1994

Main features: Open and participatory decision process Planning scenarios that consider changing

conditions Consideration of institutional context

IRP’s in relation to other plans

Strategic Planning (IRP’s; conceptual

analysis; policy-level planning;

examining trade-off among resource

alternatives)

Master Planning

(Capital Improvement Plans, detailed facility studies,

operational analysis)

PrelimDesign

(Environmental Impact Review,

Project Implementation

)

UWMP(Urban Water

Management Plan required by State

every 5 years; compares demand and supply only)

Mission StatementThe Pasadena Water Integrated Resources Plan will provide an achievable, long-term strategy to meet current and future water needs. The goals of the WIRP are to sustainably and cost-effectively address local and regional water supply and demand issues, reflect community values, and adapt to changing conditions.

Ideas from 1st Public Meeting Reduce percentage or portion of water used for landscaping – currently 50-70 overall Incentivize water conservation with energy nexus Real time notification to customers on water usage Have landlords provide water efficient fixtures, motivate/implement tenant conservation Educate people about irrigation and runoff – soil types/swales, etc. Encourage more efficient irrigation, e.g. drip Convert turf areas Partner with large educational institutions, landscape changes/public education

opportunity – new paradigm Landscaping contests, free landscaping to winners, etc. Explore integration of reclaimed water into City’s supply Capture what we throw away – sinks, showers, etc. Look at greywater systems Evaluate water catchments for rainwater, e.g. natural depressions Identify areas that are more suitable for groundwater recharge – consider zoning tools to

protect and maximize recharge Incentivize/rebates for redesign of sites to capture more runoff Reduce imperviousness, reasonable but meaningful X % per year Encourage new

development to store runoff on site Partner with other resource agencies to develop options that might otherwise be too

expensive, e.g. solar for desal
