Venice Pumping Plant Dual Force Main
Sewer |
|
|
PROJECT DESCRIPTION
Construct a new 54-inch diameter
force main sewer that will cross Grand Canal from
the Venice Pumping Plant (VPP) at 140 Hurricane Street
easterly to Marquesas Way, then southerly along Via
Marina crossing the Marina Del Rey and Ballona Creek
Channels to an existing Coastal Interceptor Sewer
junction structure on Vista Del Mar near Waterview
Street. The new force main will operate as a parallel
system in conjunction with the existing 48-inch force
main, which runs along the beach, to meet current
peak wet weather flows, and to add operational flexibility & reliability.
Construction is tentatively set for August 2010.

PROPOSED
CONSTRUCTION METHOD
The
primary construction method will be microtunneling. The
southern-most 1300 feet will require trenching. Microtunneling
between pits spaced 800 to 1000 feet apart reduces the
extent of impact. Through traffic will be maintained
at all times, with minimal detours.

PROPOSE
A New Force Main Is Needed Because:
- During severe wet weather, peak flows to
VPP have exceeded the capacity of the only
existing force main that carries wastewater
away from the plant. Without more capacity
to carry wastewater away from the plant there
is a risk of spilling onto city streets and
surface waters.
- Currently, all of the wastewater from VPP
is carried in one 50-year-old sewer. Since
it is in constant use, that sewer cannot
be shut down for inspection or maintenance.
- Redundancy is needed to protect against
spillage in the event that one of the sewers
fails.
PROJECT
STATUS
The
City Council certified the EIR on January 12, 2010, thereby
approving the recommended alignment route on Via Marina-north
of the Marina entrance Channel-and on Pacific Ave and
Vista del Mar- south of Ballona Creek. Los Angeles County
subsequently filed a lawsuit against the City, challenging
the EIR and the selection of the proposed route for this
pipe. On 7/27/2011, the LA County Superior Court issued
a ruling on the case, upholding the certification of
the EIR. However, on two other causes of action; namely
violation of the Public Utilities Code and Declaratory
Relief, the court ruled against the City, effectively
preventing the City from proceeding with the construction
of the project at this time. The City has appealed the
court ruling and the case will go before the Appellate
Court in October 2012.
A critical part of the Venice
Dual Force Main project includes the replacement
of the aging pump discharge manifold for the Venice
Pumping Plant, located outside of the Plant beneath
Hurricane Street. Due to the urgency for completing
this part of the project, the City has created a
separate project to address the manifold replacement.
This project will start construction in April 2012
and will take 18 months to complete.
