Subject: Water Quality Discussion - Hard Water, Taste & Odor Concerns
SUMMARY:
Taste and odor concerns along with water hardness are topics often raised by District customers.
Staff will present a verbal report on these issues and provide an update on recent changes in
system operations.
DISCUSSION:
Dealing with taste and odor resulting from the mixture of imported water and groundwater has
always been a challenge for the District. Typically, the District supplies half of its service area with
groundwater and the other half with imported water. However, because of the variability in supply
and demand, certain portions of the District are sometimes served with a mixture of both water
supplies. The disinfection process for each water source is different. Groundwater is disinfected
with free chlorine and imported water is disinfected with chloramine (a combination of chlorine and
ammonia). The mixing of the two can sometimes result in taste and odor complaints from District
customers.
Hard water is also a source of customer complaints, especially those being served primarily with
groundwater. Because of the nature of the aquifer, where water is stored between layers of rock
and sand, minerals such as calcium and magnesium get dissolved into the water and pumped out
of the ground. Much of the District's groundwater contains fairly high hardness levels. While
minerals are beneficial for drinking, high water hardness can lead to mineral deposits on glassware
and dishes, a source of complaints from customers.
Staff will present a verbal report on the topics of water hardness and taste and odor to the PEO
Committee.

Subject: 2011 MWD Shutdown
SUMMARY:
The Metropolitan Water District of Southern California (MWD) has scheduled a shutdown of the
Robert B. Diemer Treatment Plant and its influent and effluent transmission pipelines from 12:01
A.M. on Sunday, February 27, 2011 through midnight on Saturday, March 5, 2011. The purpose of
the shutdown is to construct treatment facility improvements and to perform critical pipeline
maintenance. During this period, the Yorba Linda Water District will not have access to imported
water supplies, which typically make up over 50% of its water supply resources overall. These
resources normally supply 100% of the water demands to the eastern sections of the District's
service areas (to the Hidden Hills area and eastward) and to elevations served above the 780
Pressure Zones. In preparation for the 2011 MWD System Shutdown, the Production Division has
developed an operating plan that strives to achieve uninterrupted water service to our customers
throughout the shutdown period. Attached is a staff report outlining this plan and the actions
initiated prior to the shutdown.

SUBJECT: Operating Plan for 2011 Seven Day Metropolitan Water District (MWD)
Shutdown. (12:01 A.M. February 27, 2011 through midnight March 5, 2011)
The Metropolitan Water District of Southern California (MWD) has scheduled a
shutdown of their Diemer Filtration Plant in Yorba Linda, along with major transmission
pipelines to and from this facility. This shutdown has been scheduled to construct
treatment facility improvements and to facilitate critical pipeline maintenance. In
preparation for this shutdown, the YLWD Production Division has evaluated our
groundwater delivery facilities and current water system demands. We have developed
a plan to achieve uninterrupted service to our customers during the seven day MWD
shutdown, which includes the following:
1. Evaluation of Current Demands. During the past two weeks our water demands
averaged approximately 15 million gallons per day (MGD), with 3.5 MGD of these
demands supplied from MWD connections. We will monitor the weather forecast for
the weeks leading up to the shutdown. We have identified areas of potential
shortfalls if demands increase or if the shutdown has to be extended beyond the
seven days.
2. YLWD System Preparation. In preparing for the MWD shut down, Production staff
has evaluated our system to determine operational conditions. The following is a list
of system conditions at the time of this report and the expected conditions during the
shutdown period.
• Well No. 1 is scheduled to be out of service and will not to be available during
this shutdown.
1
• The District's eight other wells, with a combined capacity of 11,000 gpm, are
operational and available.
• We will fill all reservoir storage to near full capacity immediately prior to the
shutdown.
• We have installed and tested a portable pump at the Fairmont Reservoir and
Booster Pump Station site. This pump is available to supply an additional
1,500 gallons per minute (gpm) from Pressure Zone 3 (675 feet above mean
sea level) to Pressure Zone 4 (780 feet above mean sea level).
The following notifications are planned:
3. Public Notification of the shutdown. Production staff will notify Black Gold Golf
Club of this shutdown with a letter sent as a follow up.
• The City of Yorba Linda will be notified of the shutdown by written
correspondence (i.e. a letter).
• Placentia Yorba Linda School District will be notified in writing.
• The District's two portable message boards will be serviced to ensure they
will be available if needed.
• A notification will be on the District's web site.
• It may be necessary to ask our customers for additional conservation efforts.
This effort will depend on water demands and weather conditions leading up
to the shutdown.
4. Temporary Water Service Interruptions (Irrigation and Construction Water
Services). If demands are exceeding planned estimates and water supplies from
storage reservoirs are showing signs of rapid depletion, non-essential irrigation and
water used for construction purposes may be temporarily halted for the duration of
the MWD shutdown. This interruption of non-essential water use will be
accomplished cooperatively through the City Public Works and Park and
Recreations Departments and/or by manually turning off service at the meters or
irrigation backflow devices if necessary.

SUBJECT: Groundwater Producers Meeting, January 12, 2011
1 attended the Groundwater Producers (GWP) Meeting on January 12 at OCWD. A
summary of each item discussed is as follows:
1. Water Quality Update. OCWD staff provided an update on water quality issues
including the following:
a. Revised Reporting Levels for 1-4 Dioxane. As OCWD reported at the
December GWP meeting, new advisory levels were issued by CDPH in
November for the chemical 1-4 Dioxane (1-4-D). The Notification Level
was reduced from 3 parts per billion (ppb) to 1 ppb, and the Response
Level from 300 to 35 ppb. In 2001, low levels were found in wells of
Newport Beach, Fountain Valley, Mesa Consolidated WD, and IRWD. No
1-4-D was found above the detection level for the wells of YLWD at that
time or since.
b. New Draft Public Health Goal (PHG) for Chromium-6 (CrVI). The State
issued a reduced PHG of 20 parts per trillion (ppt) on December 31, 2010.
A PHG is an advisory level, not an enforceable regulatory standard. The
Department of Public Health is now tasked with establishing the
appropriate MCL for CrVI which could take two to three years. Currently
YLWD wells have an average of 0.1 ppb CrVI. This concentration is below
the required detection limit of 1.0 ppb.
c. State is soliciting comments on a proposed revised PHG for
Perchlorate at 1.0 ppb. The existing PHG and MCL is 6.0 ppb. YLWD
has an average Perchlorate concentration of less than 2.5 ppb.
d. U.S. Dept of Health & Human Services is recommending that fluoride
in drinking water be no more than 0.7 parts per million (ppm).
YLWD's groundwater has an average of 0.50 ppm. The imported water
from MWD has a fluoride concentration of 0.7-0.9 ppm.

2. Final Review of "Transparency in Government" Letter. As reported by
OCWD in December, the OCWD Board is requesting support from all
Groundwater Producers for a letter they propose to send to Governor Brown,
stating that "OCWD and its local groundwater producers, representing 2.4 million
residents in north and central Orange County, support recent government reform
measures in response to the City of Bell salary scandal and encourage
immediate action to pass measures increasing government compensation
transparency during this legislative session." OCWD staff noted that this letter
and the support of the Groundwater Producers is requested to increase
accountability and restore public faith in state and local government (including
special districts). There were no further comments at the January 12 meeting;
therefore, the letter will be finalized and sent to the governor.
3. Update on Santa Ana River and Prado Dam Recharge Activities. OCWD
reported on the effect of the December 2010 storms, in which there were 8
inches of rain in six days, and a record total of 10.5 inches for the month
measured at OCWD Field Headquarters in Anaheim. In late December, there
was a record-volume of 100,000 acre feet behind Prado Dam. The Army Corps
limited discharge from the dam to 3,000 cfs (i.e., 6,000 AF/day) to minimize scour
of the river bed and protect the SARI sewer main buried below. Storage behind
Prado is currently in the range of 10,000 AF. Discharge from the dam will be
reduced to 300-500 cfs for diversion from the river to the District's recharge
basins. It was also noted that Irvine Lake topped out and is spilling to Santiago
Creek, which filled and topped out the District's Santiago Recharge Basins in
Orange with 11,000 AF. In closing they noted, that while December was record-
breaking there is no guarantee that the rains will continue. The current prediction
from the National Weather Service is for dryer than normal weather patterns over
the next three months.
4. Preparation of BPP and RA Projections for FY 2011-12. OCWD reported that
they project the BPP to be 62-65% and the RA to be $255-265 next FY. There
will be more detailed information and perhaps a better estimate on the District's
website on January 14.
5. FY 2011-12 Budget-Preparation Schedule. OCWD reported that the District's
draft budget for next FY will be presented to the Board on March 2 and to the
GWP on March 9. Major issues impacting the budget are 7.5% MWD rate
increase in January 2012 and the need for higher OCWD rates if the Board
approves proceeding with the 30 MGD expansion of GWRS Project.
6. MWD Discounted Replenishment Water Discussion. OCWD reported that
snow pack is about 200% of normal and many of the reservoirs in the state are
much higher than before. MWD may be looking for ways to sell more water and
get more into storage. In the past, MWD offered water for replenishment at
discounted rates during wet years. OCWD is pursuing this, but it is doubtful due
to political and other issues. Updates will follow in the months ahead.
7. Discussion of Annexation Request Issues. Information was provided and
discussed on the following issues:
a. Current and Future Sources of Water for GW Basin Recharge.
OCWD provided a handout showing recharge supplies of approximately
2
294,000 AF/yr in 2011 and 347,000 AF/yr in 2035. The latter figure
includes the first 30,000 AF expansion of GWRS but not the potential final
30,000 AF expansion.
b. Current and Future Recharge Capacity. OCWD noted that they will
continue to pursue cost-effective projects to expand recharge capacity but
did not elaborate due to time constraints.
c. Future Total Water Demands. OCWD provided a handout showing total
water demands (met by import and groundwater) of 455,000 AF/yr in
2012. For 2035, they showed additional demands of 68,000 AF/yr due to
infill, 15,100 AF/yr from current annexation request, and 27,000 AF/yr for
ultimate build-out in IRWD. The combined total of 565,100 AF/yr is
viewed as the projected ultimate demand by the groundwater producers, if
all annexation requests are approved.
d. Estimated Imported Water Connection Capacity. OCWD provided a
handout prepared by MWDOC showing the MWD connection capacity of
each groundwater producer in cfs and AF/yr and compared that to the
total water demand of each agency. In all cases, the MWD delivery
capacity exceeded the total water demand, indicating that each can meet
demand from MWD supply even if the BPP is significantly reduced.
However, it was noted that this could come at higher costs and with
potential penalties by MWD.
e. Other. OCWD noted that at the next Annexation Workshop, they will
provide an estimate of the BPP with and without annexation demands.

Subject: Amendment No. 3 to MWH Americas Professional Services Agreement -
Construction Support Services for the Highland Booster Pump Station
Replacement
SUMMARY:
Construction of the new Highland Booster Pump Station (BPS) commenced in December and is
proceeding on schedule. District staff and the project team determined that construction support
services are needed from MWH, which were not included in the original scope of work for the
Professional Services Agreement (PSA). At the District's request, MWH prepared a proposal for
additional construction support services, which staff has reviewed and recommends for approval.
STAFF RECOMMENDATION:
That the Committee recommend the Board of Directors approve Amendment No. 3 to the
Professional Services Agreement (PSA) with MWH Americas, in the amount of $219,791, for
additional construction support services for the Highland Booster Pump Station Replacement and
Expansion Project, Job No. 200814.
DISCUSSION:
When the Request for Proposals (RFP) was initially prepared by District staff for the new pump
station project, the Scope of Work included primarily the engineering design services and limited
Construction Phase Services. It was understood by District staff that this was a minimum level of
services and that a considerably greater effort would be required, due to the anticipated complexity
of the project. The full scope of Construction Phase Services required could not be accurately
determined until after the design criteria was approved by the project team and the design was
completed relative to mechanical equipment, electrical systems, control systems, and other project
elements.
The purpose of including a basic or minimum level of Construction Management (CM) services in
the RFP was to have the proposing firms provide information on their proposed CM staff, approach,
experience and staff hours per task. This information helped YLWD staff determine the
qualifications and capabilities of the proposing firms to perform all of the necessary tasks for the
project, from permitting through design and construction management. These efforts assisted in the
selection of MWH Americas as the District's preferred consultant for the project.
After the completion of design, award of the construction contract, and receipt of initial shop
drawings from the construction contractor, it was possible to more accurately project the extra work
hours and tasks required for CM beyond those listed in the original RFP. Following discussions
between District and MWH staff regarding necessary CM tasks and level of effort, MWH submitted
a letter proposal describing the additional tasks, hours and fee, a copy of which is attached.
In summary the additional tasks would include the following:
Submittals/Shop Drawings. The original PSA includes review of 30 submittals and shop drawings.
The amendment includes services for an additional 45 submittals.
Requests for Information (BFI's). The original PSA includes review of 12 RFI submittals. The
amendment includes services for an additional 48 submittals.
Change Order Preparation. The original PSA did not include these services. The amendment
budgets 100 hours to draft and process change order documents.
Review Change Requests. The original PSA did not include these services. The amendment adds
80 manhours to review change order requests from the contractor.
Meetings. The original PSA included 9 meetings. The amendment includes 8 additional meetings.
Southern California Edison Permit Coordination. MWH will subcontract with RBF Consulting
(the project electrical engineer) to continue their support of the SCE Generating Facility
Interconnection Application in accordance with SCE Rule 21. Added is $8,520 for this task.
Instrumentation and Programming Support. The original PSA did not include support relating to
the control systems, programming of the PLC and Wonderware software development. Added is a
subcontract under MWH with MSO Technologies for $20,000.
Specialty Inspections. The original PSA did not include support for special inspections, including
electrical and instrumentation. MWH will provide an electrical and instrumentation engineer to
observe and inspect installations as needed. Added is $22,840 for this task.
Final Inspection and Startup. MWH will assist the District in the final walk through with inspection
of the electrical, instrumentation and startup of the engines, motors and pumps. The amendment
adds $21,033 for this task.
If approved, Amendment No. 3 for $219,791 will increase the PSA total from $587,027 to $806,818.
Within that total, the tasks and fee for CM Services will increase from $60,000 to $279,791. That
total equates to approximately 6.2% of the $4,525,800 construction cost. This percentage compares
very favorably to other recent complex construction projects completed, including 6.5% for CM for
the Lakeview Booster Station, 6.4% CM for the Highland Reservoir, and 6.9% CM for the Hidden
Hills Reservoir construction.
District staff has reviewed the proposed change order and discussed it with staff of MWH. Staff
believes that the proposed scope and fee are necessary and appropriate for the additional services
and recommend approval of Amendment No. 3 for $219,791.
PRIOR RELEVANT BOARD ACTION(S):
On July 9, 2009, the Board of Directors approved the award of the Professional Services
Agreement for the Highland Booster Pump Station Replacement Project to MWH Americas, for a
fee not to exceed $469,593. On January 28, 2010 the Board of Directors approved Amendment No.
1 for a fee not to exceed $91,940. On February 11, 2010 the Board of Directors approved
Amendment No. 2 for a fee not to exceed $18,929.

EXHIBIT A
SCOPE OF WORK
The project construction for Highland Booster Station Replacement is expected to require
approximately thirteen (13) months of as-needed support. The estimate below is based
on overall completion of the contract for engineering services during construction.
Record drawing preparation is included in our original contract. If the construction
contract period extends beyond thirteen months from the notice to proceed, adjustments
for inflation for work performed after that date may be required for work aside from
preparation of record drawings.
MWH will review shop drawings for the project for conformance with the contract
documents. Our contract included some submittals. We are requesting a budget for an
additional 45 submittals. MWH will provide a written response to each of the shop
drawings with a recommendation for the contractor's next course of action. Quotation of
hours and cost is based on an estimated average of 4 hours of review and processing
time for original submittals. It is estimated that 10 submittals will be resubmitted to
incorporate comments from the review of the initial submittal. Each re-submittal will
require an estimated 1.5 hours of review and processing time.
MWH will respond to written requests for information/clarification from the contractor
during construction. Our contract included 12 RFI's. We are requesting budget for an
additional 48 RFI's. It is assumed that MWH will respond to 60 RFIs during the course of
the project. Quotation of hours and cost is based on an estimated average of 4 hours of
review and processing time.
MWH will issue Contract drawing Clarification, as requested by the District to support
construction activities. We will notify the District of any such requested deviations or
substitutions and when necessary provide the District with a recommendation concerning
the same. MWH will prepare change orders during the construction of the project. It is
estimated that 100 hours may be required to draft and process change order documents
during the course of the project. Our contract did not include a budget for change order
preparation or review.
MWH will review change order requests to support the District. Change order requests
will be reviewed for compliance with the contract documents and reasonableness of
cost/time estimates. MWH will respond to requests directly to the District. It is estimated
80 hours for review of contractor change orders.

YLWD -2- January 24, 2011
MWH will attend project meetings and site visit at the request of the District during the
construction. It is assumed that one kick-off meeting, fifteen (15) site visits/meetings and
a concrete conference will be held during the construction of the project. Two MWH staff
are budgeted for each meeting. Our contract included nine (9) meetings during
construction. MWH will attend these additional 8 meetings, as requested by the District.
MWH will subcontract with RBF to continue their support of the SCE Generating Facility
Interconnection Application in accordance with SCE Rule 21. The contractor will require
additional information during the submittal process to make the application. RBF will
assist the contractor by responding to questions from SCE. It is assumed one meeting
will be held at the project site with SCE.
MWH will subconsult with MSO Technologies Inc. to provide support to the District
relating to questions on the control systems, programming of the PLC and Wondware
development. MSO will support the District in the review of design questions,
instrumentation calibration questions and meetings.
The District will require assistance during construction in performing inspection of the
electrical and instrumentation systems. MWH will provide an electrical and
instrumentation engineer to observe and inspect the installation of the electrical and
instrumentation. It is assumed there will be no factory inspection of the motor control
center of electrical cabinets. MWH may also perform up to 80 hours of special inspection
of the mechanical equipment during construction. The equipment will be inspected in the
field prior to installation.
The District will require special inspection at the completion of construction for
development of a final punchlist. MWH will assist the District in the final walk through with
inspection of electrical and instrumentation. The mechanical engineer will also be
present during the startup of the engines, motors and pumps. It is assumed four
engineers will be present during the walk through. It is estimated the final inspection will
be one-day with a follow-up meeting at the District.
Pump station startup will require support by the electrical engineer and mechanical
engineer to witness startup and assist in adjustments to mechanical and electrical
equipment.
