On Thursday, Feb. 8, Golden State Water lifted the precautionary Boil Water Notice that was issued on Feb. 6 to approximately 2,000 customers impacted by the recent service interruption and loss of pressure in the northern portion of the Claremont system. The temporary Boil Water Notice was issued out of an abundance of caution while crews flushed the lines and tested for water quality.

Golden State Water, in conjunction with the State Water Resources Control Board’s Division of Drinking Water, has determined that the water is safe to drink and use for cooking purposes. It is no longer necessary to boil tap water or consume bottled water.

As a precaution, customers are advised to dispose of any ice or beverages made while the precautionary Boil Water Notice was active. Some customers may notice the temporary presence of air in their water lines; this is normal and can be corrected by flushing the pipes in their home. If customers notice a drop or change in pressure, they should call 1-800-999-4033 immediately so crews can be dispatched to investigate.

Approximately 2,000 customers in Golden State Water Company’s (Golden State Water) Claremont service area experienced a temporary water service interruption on Tuesday, Feb. 6, because of higher-than-anticipated system demand during a planned maintenance shutdown at a treatment plant operated by our local wholesale provider.

Water service has been restored to the system, and the precautionary Boil Water Notice that was issued for impacted customers has been lifted (effective Feb. 8 at 2 pm).

Based on data from our water supply facilities, the service interruptions were located in two areas:

  1. Primarily north of Miramar Avenue, to the northern City limits of Claremont
    and East of Indian Hill to the City limits of Claremont
  2. South of the 210 Freeway, North of Foothill, East of Stowe, West of Monte
    Vista & West of Corporate Center
