AGENDA TITLE: Receive Update on Emergency Condition at White Slough Water Pollution Control
Facility Digesters No. 1 and No. 2
MEETING DATE: April 15, 2015
PREPARED BY: Public Works Director
RECOMMENDED ACTION: Receive update on emergency condition at White Slough Water
Pollution Control Facility Digesters No. 1 and No. 2.
BACKGROUND INFORMATION: White Slough Water Pollution Control Facility (WSWPCF) has four
covered anaerobic digesters that serve the purpose of breaking
down sewage sludge that enters the plant. On July 16, 2014,
Council declared an emergency condition in response to concurrent roof failures on Digesters No. 1 and
No. 2. Public contract code requires Council to review the emergency action at its next regularly -scheduled
meeting and each regularly -scheduled meeting thereafter until the emergency is terminated.
The completed Digester No. 2 roof structure is installed, and work to begin start up procedures continues.
Digester No. 2 may be in service at the time of this Council meeting.
As noted in the April 1St Council update, the new roof for Digester No. 1 has been fabricated, coated and set
aside until it is time for installation. The task of removing the contents of Digester No. 1 will begin once
Digester No. 2 is in service.
The procurement and construction schedule reflecting project milestones is provided below. The work is
progressing on the original schedule, and there is no substantial change from last report.
