Public Comment
Supply Oriented
Pasadena Water and Power
• “Non-Ag Human Water Use is Only 10% of CA
Total Water Use”
> Targeting urban use affects many businesses
> Penalizing someone for watering enough to keep their
property values from diminishing is out of line and wrong
> Must focus on macro-issues (securing supplies)
• Maximize Water Reuse:
> Promote onsite reuse: Graywater systems
> Accelerate PWP’s Recycled Water Pipeline Project
• Capture Rainfall & Stormwater
> Recharge aquifer: Bio-swales, rain gardens
> Onsite use: Rain barrels, cisterns

Emergency Regulations Digest
25% Statewide Conservation Goal
Pasadena Water and Power
…The State Water Board expects that
most of the savings would come from
reduction in or elimination of irrigation
of ornamental landscapes with potable
water conservation…The requirement
would, in some cases, entail restrictions
on use by other customer classes…
19
Emergency Regulations Digest
Watering Medians
Pasadena Water and Power
A prohibition on the irrigations with potable
water of ornamental turf on public street
medians is necessary to promote water
conservation, minimize the potential for
waste and unreasonable use...does not
provide for domestic use, sanitation, or fire
protection, which are the primary needs
that public water supply distributors must
meet during drought periods

Additional Water Conservation Ideas
for Discussion
Pasadena Water and Power
Require that all swimming pools, wading pools, or spas be covered when not in use
with acceptable protection designed to decrease water evaporation
Mandate landscape irrigation surveys for large residential customers
Mandatory retrofits of indoor plumbing fixtures on all multi-family properties
Mandatory retrofits of indoor plumbing fixtures upon resale of properties
Require all multi-family properties to have individual meters
Require all new properties to install dual piping to use recycled water
Require compostable toilets for new construction
Work with local Plumbers to provide 10%-20% coupons to go toward the cost of
repairing water leaks or adjust a customer’s irrigation controller
Develop on site storm water capture/bio swale program
Water Rates and Drought Penalties
Pasadena Water and Power
• Proposition 218 Limits Ability to Encourage
Conservation Through Rates and Penalties
• Legal Challenges to Tiered, Budget-Based,
and Drought Rates Escalating
• PWP Rates are Cost Based
