Waste Water Treatment Plant

Here's a step-by-step guide describing what happens at

each stage of the treatment process and how pollutants

are removed to help keep our waterways clean.


Primary treatment of wastewater

The Primary Treatment Process

1. Screening:

5. Removing scum:

2. Pumping:

6. Killing bacteria:

3. Aerating:

R. Wastewater Residuals:

4. Removing sludge


Primary Treatment


Preliminary Treatment


Grit Tanks


Primary Clarifiers


Secondary Treatment - Aeration Tanks


Carbon Cycle - Metabolism ReactionBacterial Decomposition of Organic Waster


Sludge/Solids Treatment


Sludge Dewatering and Drying


Secondary/Final Clarifier Tanks


Chlorination Tanks


Final Water Stats


Example : WHITTIER NARROWS

WHITTIER NARROWSWATER RECLAMATION PLANT(WRP)


Example : WHITTIER NARROWS (2)

  • DIRECTIONS:The Whittier Narrows WRP is located at 301 N. Rosemead Blvd., El Monte. The plant occupies 27 acres south of the Pomona (60) Freeway.OPERATION:The Whittier Narrows WRP was the first reclamation plant built by the Districts in 1962. It provides primary, secondary and tertiary treatment for 15 million gallons of wastewater per day (see flow diagram below). The plant serves a population of approximately 150,000 people. Virtually all of the purified water is reused as groundwater recharge into the Rio Hondo and San Gabriel Coastal Spreading Grounds or for irrigation at an adjacent nursery.
