Original Press Release
May 23, 2017 - Construction work today caused localized low pressure in the City's water supply system affecting approximately 100 homes, southwest of Island Crest Park. See map here. (Note: The original map was updated at 7:15pm to reflect approx 30 additional locations that were part of a separate planned water outage area today [hydrant work] and were also door-tagged this evening).
In an abundance of caution, the City recommends those homes to boil their water for the next 24-48 hours. To treat the affected area, water service is currently shut off, but will be restored by early evening.
The City is testing the supply and inform residents when that testing is complete. This precautionary notice is being issued because the low pressure may have allowed contaminants to enter the system. Door tags are being placed at affected homes.
When water service is turned back on, PLEASE BOIL YOUR WATER for 1 minute before using. Boiled or bottled water should be used for drinking, making ice, washing dishes, brushing teeth, and preparing food until further notice.
