A 30-inch broken pipe caused flooding at the Post Point Wastewater Treatment Plant in Bellingham over the weekend.

The Bellingham Herald reports city crews were cleaning up after the flooding on Saturday. The city reported Sunday that the plant was still in emergency operations.

Eric Johnston, with the Public Works Department, said the failed pipe means the plant will only provide basic treatment to wastewater until it's fixed.

He says it shouldn't impact day-to-day water users in the city.

The broken pipe led to three feet of flooding in underground sections of the plant, and a shutdown of the secondary treatment process.

"At no point was human health at risk. The city does not anticipate any need for a closure of beach access or shellfish restrictions," Johnston said.

Johnson said lab analysis of the water quality showed extremely low fecal coliform counts in the primary treated water discharged to Bellingham Bay.

The city notified permitting agencies including the state ecology and health departments and the Whatcom County Health Department.
