Plant/Process Description:
Drinking water comes from Evergreen Lake. Water
flows into Evergreen Lake via Upper Bear Creek
from the Mount Evans drainage basin.
The Water Department is responsible for the
operation and maintenance of the water treatment
plant and the distribution system (pump stations
and reservoirs). Operations of the water
treatment plant consist of sampling and testing,
evaluating, monitoring the system using computer
technologies, and making equipment and process
adjustments. Operations of the distribution
system include adjusting pumps and reservoir
levels to meet the needs of the community.
Summary of Water Treatment Process
1. Chemical injection to raw water.
-Chlorine Dioxide: Used to remove iron,
manganese, and taste and odor causing
contaminants.
-Aluminum Sulfate: Used to attract particles
together.
-Polymer: Used to attract particles together.
-Soda Ash: Used to adjust pH for chemical
treatment.
2. Flocculation
-This process is a slow mix of the water and
chemicals. As the chemicals and small particles
come into contact with each other, the small
particles begin combining together to form bigger
particles.
3. Sedimentation
-The particles that are formed in the
flocculation process settle to the bottom of the
tank. Clear water or settled water is drawn off
of the top and flows to the sand filters.
4. Filtration
-Even though the water has been chemically
treated and settled, really small partcles are
still present. Filtering the water through sand
filters removes these small particles that will
not settle.
5. Chemical Injection to treated water
-Chlorine: Used to disinfect the water.
-Fluoride: Used to prevent tooth decay.
-Soda Ash: Used to adjust pH for corrosion
control.
6. Membrane Filtration Treatment
-Chemical injection to raw water.
-Chlorine Dioxide: Used to remove iron,
manganese, and taste and odor causing
contaminants.
-Aluminum Sulfate: Used to attract particles
together.
-Soda Ash: Used to adjust pH for chemical
treatment.
7. Flocculation
-This process is a slow mix of the water and
chemicals. As the chemicals and small particles
come into contact with each other, the small
particles begin combining together to form bigger
particles.
8. Membrane Filtration
-This process filters all particles bigger than
0.1 micron in size. Membrane filtration filters
particles so small that a person needs a
microscope to see them.
9. Chemical Injection to treated water
-Chlorine: Used to disinfect the water.
-Fluoride: Used to prevent tooth decay.
-Soda Ash: Used to adjust pH for corrosion
control.
