Providing safe and reliable tap water is our highest priority. That is why we test our water every day. Sometimes we detect contamination, such as E. coli or enterococci. Bacteria cannot enter our tap water on their own. They always come from an external source, for example, as a result of maintenance work or a burst water main. When this happens, we can no longer guarantee the quality of the tap water, and we issue a boil-water advisory.

Unfortunately, tap water is sometimes not clean enough for direct use. This may be the result of a malfunction, leakage or maintenance work. For example, when we are working on a water main, there is a small chance that a contamination could enter the pipe. If this happens, we will issue a boil-water advisory. Sometimes, we issue a boil-water advisory as a precaution. This happens when we cannot be certain that the tap water is completely safe.
