Treatment of the District's Drinking
Water |
|
No Filtration |
BWD
has an exemption from filtration from the EPA due to its exceptionally
high water quality. Only 11 surface water supplies in Maine do not have to
filter their water. |
|
Ozone |
At
the Butler Ozone Treatment Plant, ozone is bubbled into the water. It is
our primary disinfectant used to destroy microorganisms. |
Fluoride
|
The
city of Bangor voted in 1967 to add fluoride to the water. Fluoride helps
prevent tooth decay. |
|
Chloramines |
Ammonia
and chlorine are combined at our treatment facility to make chloramines.
Chloramines provide a disinfectant residual in the distribution system. |
|
Soda Ash
 |
To
help prevent corrosion of pipes and household plumbing, the District adds
soda ash to minimize the water’s corrosiveness by reducing its acidity
and raising the pH. Soda ash also increases the alkalinity of the water
which helps stabilize the pH throughout the distribution system.

|
Because of Floods Pond's
high quality, these are the only treatment processes required to ensure
safe water at the tap. |
