Water Filtration Process

Even with a high-quality drinking water source we still have to filter and disinfect the river water to deliver safe drinking water to your tap.  At the Hayden Bridge Water Filtration Plant we use a three step process to turn water from the McKenzie River into safe drinking water.

1) Before filtration

• Sometimes we add carbon to improve taste and odor.

• Raw water from the river can be cloudy due to soil particles floating in the water. We add alum to bind the soil particles into clumps. The clumps then fall to the bottom of the settling basin, and the water flows into the filters.

2) Filtration

• Following settling, the water travels through a multi-layered filtration process that removes any remaining clumps and small particles.

3) After filtration

• We add chlorine to maintain the purity of the water throughout our distribution system.

• We adjust pH with sodium hydroxide to reduce corrosion in our distribution system and in your home or business's plumbing system.
