AGENDA TITLE: Adopt Resolution Authorizing City Manager to Execute Contract Change Order
with 111116stern Water Constructors, Inc,, of Santa Rosa, for Payment of Services
for Work Associated with Emergency Repair of 48 -Inch Domestic Sewer Outfall
Pipe at White Slough Water Pollution Control Facility and Appropriating $88,000
MEETING DATE: May 3, 2006
PREPARED BY: Public Works Director
RECOMMENDED ACTION: That the City Council adopt a resolution authorizing the City Manager to
execute a contract change order with Western Water Constructors, Inc., of
Santa Rosa, for the payment of services for work associated with the
emergency repair of the 48 -inch domestic sewer outfall pipe at the
White Slough Water Pollution Control Facility (WSWPCF) and appropriating $88,000.
BACKGROUND INFORMATION: On March 29, 2006, during work being performed on the WSWPCF
headworks gate replacement project, the contractor, Western Water, Inc.,
discovered the crown of the 48 -inch diameter domestic outfall pipeline
(Outfall) to be completely corroded adjacent to a manhole structure.
Upon further investigation of the manhole, a large section of collapsed pipe was discovered. The manhole
was being prepared for a planned bypass procedure to divert wastewater flows from the domestic outfall to the
plant headworks. That evening after inspecting the site, City staff verbally authorized the contractor to
mobilize equipment the following morning in preparation to make the repair of the collapsed pipe.
The repair involved relocating the planned bypass structure, portable power supply and standby pump in order
to prevent any potential non -permitted discharge.
Once the bypass was established, the contractor was able to cautiously excavate the area near the collapse
until a stable section of Outfall pipe was found. A section of new pipe was installed and mortared into place
on April 5, 2006. Flow was re-established in the Outfall pipeline shortly thereafter.
Included in the appropriation is $15,000 for repair or replacement of nine motors within the plant that were
damaged by the high plant flows created by this work and $385 for security services to watch the equipment
during the overnight hours.
FISCAL IMPACT: Not applicable. This work was undertaken under the terms of the City's
contract with Western Water Constructors for the installation of tertiary filters
and UV disinfection ($7,484,600) and subsequent change orders for standby
generator installation ($280,000) and headworks modifications ($260,670).
FUNDING AVAILABLE: 2004 Certificates of Participation proceeds
