Clean Water System

The purpose of the Clean Water System is to produce drinkable water for:

Drinkable Water Subsystem

  • Goal: Produce over 500,000 gallons of drinkable water per day.
  • Source: Wells on reservation lands.

Extraction by pumping from wells rather than directly from the South Umpqua River has two distinct advantages:

  • Better quality of the source water.
  • Environmental benefits to the river itself.

The Drinkable Water Flowchart depicts the main components in the Drinkable Water Subsystem.

    • 360 acre feet.
    • 85 feet deep.
    • 80 mil liner with subliner.
    • Fenced to exclude wildlife.
  • Sediment Basin:
    • The purpose of the sediment basin is to clarify the drinking water by removing the turbidity.
    • Input pumped from Reservoir.
    • Output gravity fed into Treatment Facility.
  • Treatment Facility:
    • The purpose of the Treatment Facility is to kill bacteria by treating the water with ultra-violet light.
    • Input gravity fed from Sediment Basin.
    • Output after slight chlorination pumped into Storage Tank.
  • Clean Water Storage Tank:
    • Input pumped from Treatment Facility.
    • Over 1,000,000 gallon capacity.
