ATTACHMENT - ITEM 4.3 Alternate Water Sources: Infrastructure Improvement Projects:  Recycle Water- Recycle Water Treatment Plants and Distribution Systems.  Storm surface water collection, treatment and distribution.

ATTACHMENT - ITEM 4.3 Conservation  Rainwater Catchment.  Grey Water Recycle.  Black Water Recycle.  Septic Tank Effluent Pump, S.T.E.P., systems.  Drought resistant or native landscaping.  Water saving appliances.

ATTACHMENT - ITEM 4.3 Governing Criteria: Alternate plans which provide the most benefit to:  Environment.  Economy  Recreational Opportunities.

ATTACHMENT - ITEM 4.3 Indirect Potable Reuse: • Build an Advanced Recycle Water Treatment Plant. • Inject water into groundwater basin for quaternary treatment.

ATTACHMENT - ITEM 4.3 Existing Facilities used as Models: • Santa Clara Valley Water District/City of San Jose Advanced Recycle Plant. Cost 57 Million. Capacity 10 MGD. • Orange County ’ s Indirect Potable Reuse System. Upgrading to 100 MGD. In my opinion, likely to prove to be one of the best systems in the world.

ATTACHMENT - ITEM 4.3 Time to Clean Up Our Act  Turbidity can be reduced by erosion control.  Pollution can be reduced by improved septic recycle water use and increased awareness of household product use.  Both our better for the environment and provide water less expensive to treat.

ATTACHMENT - ITEM 4.3 Fish Habitat  Streamside property owner awareness to protect creation of deep, shady, pools along river.  High groundwater is a critical factor- as river dries up too quickly.  End silt and septic pollution and recycle water- both help water supply and fish habitat.

ATTACHMENT - ITEM 4.3 Conclusion  Recycling water not only provides water source, but helps environment by eliminating pollution.  Infrastructure improvements combined with developing recreational areas lowers cost.  Increased flexibility of water distribution and amount of water storage allows greater security.
