10. Pure Water Supports Permit Renewal
•
Commitment to Pure Water would divert flow from Pt. Loma
•
Reduces treated water flow to the ocean
•
Supports legislative changes to the Clean Water Act to allow for “secondary equivalency”
10

11. Secondary Equivalency
•
Secondary treatment achieves certain levels of water quality in the flow to the ocean
•
We can achieve the same outcome and avoid expensive upgrades by reducing flow to the plant
•
In the process we create Pure Water, while protecting ocean water quality 11
