Up to 180,000 gallons of partially treated waste water was released into the Puget Sound between 11 p.m. Sunday and 2 a.m. Monday because of an electrical problem at the Fort Lewis, Wash., waste water treatment plant, officials announced Monday in a press release.

Officials emphasized that no completely untreated water was released during the incident. All the water that escaped had received at least primary treatment, meaning it had been stripped of solid wastes. In addition, about 45 minutes after the problem was detected, workers restored the secondary treatment process, which involves more sophisticated filtration. Chlorination, the last step in water treatment at the facility, was restored about 2 a.m.

Officials estimate that the event released up to 60,000 gallons of water that had only received the primary treatment and up to 120,000 gallons of water that had been fully treated but had not been chlorinated.
