ABSTRACT
The Lester J. Berglund Water Treatment Plant treats and delivers potable water to the City of Poway: Ifan
interruption of operation at the Water Treatment Plant occurred due to an emergency or disaster situation, Poway
has no alternate source of treated water to supply its customers beyond the maximum 23.5 million gallons of
storage in treated water reservoirs. This report suggests that the City of Poway pursue a two-way flow
connection to the San Diego County Water Authority treated water pipeline for use in the event catastrophe
prevents operation of the Berglund Plant.

SDCW A for Treated Water Deliveries During Emergency Conditions.
BACKGROUND
The City of Po way's Lester J. Berglund Water Treatment Plant (WTP) treats and delivers potable
water for the City. The Ramona Municipal Water District, on an as-needed mutual aid basis,
occasionally requests deliveries of water treated at Poway's plant. Currently, this connection is a
one-way flow from Poway to Ramona MWD. Ramona's primary source of treated water is the San
Diego County Water Authority's treated water pipeline connection from the Second Aqueduct.
In the event of a longer-term, catastrophic interruption of operation at the Poway water treatment
facility, we have no alternate source of treated water to supply Poway customers. Staff has been
evaluating alternatives to ensure a reliable supply of treated water to Poway customers under all
'scenarios.
FINDINGS
At present, the Lester J. Berglund Water Treatment Plant is the sole source of potable water to the
City of Po way. Should a long-term, catastrophic interruption of treatment operations at the Plant
occur during an emergency or disaster situation, the City of Poway has no alternate potable water
source from which to supply its citizens. Our 23.5 million gallons of treated water storage capacity

will carry the City through approximately ten days of service - albeit severely constrained service.
Lake Poway provides up to three months of raw water supply that could pass through the treatment
plant. Should a catastrophe shut down the Berglund treatment plant for longer than ten days, we
would be unable to serve our citizens. It would therefore be advisable to arrange for treated water
deliveries - purely on an emergency need basis - through another source of supply.
The metering connection through which Poway delivers treated water to the Ramona MWD is a one.
way flow assembly. Water delivered through this meter then enters the SDCW A "Ramona Pipeline"
to convey the water eastward through the Blue Sky Reserve to Ramona's pumping station.
Preliminary discussions with the San Diego County Water Authority (SDCW A) have confirmed that
it would be possible and desirable for Poway to receive water through a reconstructed connection~
The new assembly would include two-way flow meters. In addition to an emergency supply source,
a new structure would also allow the delivery and sale of treated water westward through the
"Ramona Pipeline" to other agencies.
A letter from Mr. Ergun Bakall, Chief Engineer/Assistant General Manager of the San Diego County
Water Authority, confirms the feasibility and importance of this proposed connection; a copy is
provided as Attachment A. Specifics of the design and cost implications are insufficient to bring
before the Council at this time. However, a total project cost, shared among the beneficiaries, has
been estimated at $225,000. Concurrence from the Council that we should pursue an alternate
treated water supply source to safeguard against catastrophe at the Berglund Treatment Plant will
demonstrate the support needed for SDCW A engineering staff to definitize project objectives,
scope, design and cost.

Re: Request for Treated Water Connection
Dear Mr. Williams:
The San Diego County Water Authority has conducted an in-house evaluation of a
new treated water connection providing emergency service to the City of Poway. Based on
this evaluation, it may be feasible to provide the City with a new service connection
delivering treated water, via the Ramona Pipeline, at a rate equal to approximately 8 cfs.
To continue our work, we will need from the City of Poway a written request to proceed with
the design and construction of this new service connection.
Upon receipt of this written request from the City, the Authority will contact your
office and schedule a meeting to discuss the following pertinent issues: location of a new
metering station; possible use of the existing Ramona No_ 2 metering station; connection to
Poway's distribution system; terms of an agreement to design, operate and maintain the
metering station; available capacity in the Ramona Pipeline; budgets amounts and
reimbursable costs. Pending resolution of these issues and approval from our Board of
Directors, Authority staff will proceed with the design and construction of this new service
. connection.
The Authority looks forward to working with the City on this important project.
Should you have any questions, please do not hesitate to call me at 682-4165, or Mr. David
Chamberlain at 682-4170.
