The Westside Well provides water service for the west half of Poulsbo. Similar to other wells in the area, the water from the well has moderately high levels of manganese.
Manganese is a naturally occurring mineral that causes staining and brown water or sediment in the system. It is not harmful, however it has negative aesthetic qualities and the City is required to flush water mains at an increased frequency.
The construction of the manganese treatment system at the Westside well will filter manganese out of the water at the source. In 2017 the City installed a very similar system at the Lincoln Well which services the east half of the City.
