When will the water mains be flushed in my neighborhood?
ACWWA flushes the water mains approximately once per year, in the spring. Look for signs that flushing will occur at the entrances to your neighborhood. The schedule will be updated frequently.

Occasionally, weather may delay / hinder the flushing process and emergencies may arise where ACWWA’s staff is called away from flushing for a day or two. Please call the office at 303-790-4830 or check ACWWA’s web page for updates.
