Precautionary Boil Water Advisory

Issued when the water system experiences a loss in positive water pressure (below 20 psi), typically due to a serious main break or low storage tank levels. a loss of positive water pressure indicates the existence of conditions that could allow contamination to enter the distribution system. This is the most common type of advisory, which is issued as a precaution until water samples are collected and analyzed to confirm that water quality has not been affected.

Mandatory Boil Water Order

Issued when contamination is confirmed in the water system. Customers are instructed to boil the water to kill bacteria and other organisms in the water until the issue is resolved and the notice can be lifted. Contamination from organisms, such as bacteria, viruses and parasites, can cause symptoms, including nausea, cramps, diarrhea and associated headaches.
