Intake
Using the best available technology to limit the impact on the river and its wildlife, the intake will draw water from the river and a pipeline will transport it to the treatment plant inland.

Storage
Raw water is analyzed and confirmed for quality and then stored until it is needed in the system.

Coagulation
Chemicals are added to small particles in the water, so they can form into larger particles and be removed more easily.

Clarification
Large particles, some organic and inorganic compounds, and PCB’s and radionuclides (if present), are removed from the water by settling at the bottom of a large basin.

Filtration
Small particles not removed through clarification are filtered.

Reverse Osmosis (Desalination)
Filtered water is pumped through a membrane that lets water pass through but blocks dissolved substances such as salt, organic compounds, and if present, radionuclides and viruses.

Post-Treatment
Reverse osmosis creates virtually pure (and relatively tasteless) water by removing almost all the dissolved salts and minerals, so chemicals such as lime and carbon dioxide are added to reduce the water’s corrosiveness and improve its taste.

Disinfection
In the final treatment step, the water is disinfected using a very small amount of chlorine to kill any remaining viruses.

Distribution
Following disinfection, purified water that meets or surpasses all drinking water standards is pumped to our customers for use in their homes and businesses.
