After the water
leaves the reservoir, it travels through a basin
where carbon dioxide is injected to lower the pH.
From there the water is sent to the filters
pictured below.
Filtration ensures that there is no suspended material left in the water prior to its distribution to town.
The filters are cleaned once a week. A large pump sends clean water back up through the filter media to wash away all of the debris that has accumulated since the last cleaning. |
The water
travels by gravity through the filters, a
combination of sand and gravel. After filtration,
the water is sent to the clearwell, a large
concrete, underground storage tank. On the way to
the clearwell, chlorine and fluoride are injected
into the water. The chlorine is a disinfectant
added to ensure bacteria removal and, the
fluoride is a compound used to prevent tooth
decay.
