Helping the Water Cycle

  • EPWU has been treating

wastewater and reusing it for irrigation, industrial, and construction uses since 1963.

  • It’s known as “purple pipe” or

reclaimed water.

Helping the Water Cycle

Since 1985, EPWU has been using reclaimed water treated to drinking water standards to recharge the aquifer

What is the Alternative?

  • Increased mining of aquifers
  • Increased desalination $$
  • Drastic conservation
  • Build massive pipelines = $$$$

Only purified water is sustainable

slide-12
SLIDE 12

Water used for irrigation will be treated AGAIN in a rigorous four step process to create high quality, purified water.

Advanced Purified Treatment Process

Filters

Storage Source: Treated Water

Ultraviolet Light Membrane Filtration STEP 1 STEP 2 STEP 3 STEP 4 Disinfect

slide-14
SLIDE 14

How It Works

STEP 1

  • First, the water goes through

membrane filtration, the same technology that is used at our desalination plant.

slide-15
SLIDE 15

STEP 2

  • Water is treated with

ultraviolet light, the same technology that is used at some of our plants that treat river water.

How It Works

slide-16
SLIDE 16

STEP 3

  • Then, the water goes

through a filtration process, used at all of our treatment plants

How It Works

slide-17
SLIDE 17

STEP 4

  • Then, the water is

disinfected again.

The Result

  • This is a proven technology that works.
  • Purified water is safe to drink.
  • Purified water is some of the highest

quality drinking water produced.
