Every year water providers are mandated to mail out an Annual Water Quality Report to all of their customers. Each year, CCWD, Diablo Water District, and the cities of Antioch, Martinez, and Pittsburg prepare a joint report that lists data for each water agency. You can obtain a copy of the report on line or call and request a report from these agencies at:
  • Antioch: 925-779-7009
