SUBJECT: WATER MASTER PLAN —EXECUTIVE SUMMARY AND UPDATED
RECOMMENDED CAPITAL IMPROVEMENT PROGRAM
Recommendation:
Receive and File Update to Water Master Plan and provide any comments or direction
to staff related to implementation of the recommended improvements as presented.
History:
In November 1996, the City entered into a contract with Boyle Engineering Corporation for
the development of a comprehensive Water Master Plan (WMP). A Master Plan updates
• water demand projections, analyzes supply and storage capacities, models water
transmission, distribution and fire flow needs and identifies water system improvements
and /or replacement of the aging facilities. Though the City has a moderate sized system,
it includes the operation of five pump stations, 15 major pressure reducing stations, seven
connections to the Metropolitan Water District regional system, four wells, and three
reservoirs, one of which has a floating cover. The initial Water Master Plan effort was
completed in 1999 and identified over $50 million of improvements that were planned to be
constructed over the next 20 years (by 2020). An Executive Summary from this 1999
Master Plan is attached.
In combination with this 1999 Water Master Plan effort, the City was also actively working
on major water improvements associated with the Groundwater Development Project
(GDP) during that same time period with expenditures close to $25 million. Because of
the large expenditures, including a $15 million bond issue for portions of the GDP, the
recommended Master Plan did not contemplate completing all the recommended pipeline
replacement improvements within the 20 year period. These additional pipeline
replacements would have to be completed after 2020 and beyond the initial $50 million
program (1998 dollars).
Since the Water Master Plan was completed in 1999, approximately $3.3 million per year
have been approved to complete water projects identified in that plan. In order to
coordinate WMP projects and funding with other street improvements or utility assessment
is district projects, staff has been forced to deviate from the Master Plan's proposed
schedule since around 2001. In addition, cost estimates prepared in the Master Plan

proved to be approximately 20% lower than the actual cost realized to build the projects, •
mainly as a result of the strong economy and corresponding escalation in labor and
material prices. In addition, surface restoration costs were higher than anticipated.
Discussion:
Staff contracted with Civiltec Engineering in March 2008 to update the City's Water Master
Plan. This effort included updating the hydraulic system model to include improvements
completed since 1999, running the model to verify remaining or new facility improvements
to ensure fire flow requirements are met; and reprioritizing projects to align with
replacement needs as well as other Capital Improvement Programs such as street
rehabilitations and proposed utility assessment districts. Project cost estimates were
reviewed and updated and a new funding schedule was developed. The update was
completed and submitted to the City in December 2008. Staff has since been working with
Red Oak Consulting to incorporate master plan project cost needs into the pending water
rate study, which included a review of all anticipated improvements required for the water
system that were not funded in the 1999 WMP. The updated 30 year Master Plan
identifies $88 million in improvements (2008 dollars), including replacement of older
pipelines that are beyond their useful life. Several major City water pipelines that are still
in service today date back to the 1920's.
The updated Master Plan indicates a continued need of approximately $3.5 million in
funding per year over the next ten years. The remaining 20 years may require funding •
over $6 million per year to complete the identified projects. Some of the major projects in
the next five years are centered on proposed assessment districts. In addition, old water
mains on Balboa Island are slated for replacement to improve reliability and fire protection.
In the latter 20 years of the revised plan, more projects focus on water system reliability by
replacement of larger and older pipelines throughout the system. For example, the three
main supply lines to the peninsula are at least 50 years old with one dating back to 1936.
Funding Availability:
Two subsidiary Water Funds are being maintained to segregate the resources available to
fund master improvement plan activities separate and apart from water operations. This
accounting measure helps segregate those resources that are dedicated solely for the
purpose of maintaining critical water distribution systems from those that are available to
fund water operations.
Previous water financial plans considered a minimum annual capital funding of 10% of
annual budgeted operating expenditures. The proposed master improvement plan would
require funding closer to a 20% level. In order to accommodate the master plan as
recommended, the water rates adjustments, currently being considered, contemplates a
$3.5 million dollar annual contribution (escalated at 3.5% per year) to the water capital
fund dedicated specifically for Water Master Plan improvement projects. This funding plan
represents approximately 20% of overall operating expenditures as budgeted in fiscal year
2009 -10. Debt funding of this program may need to be periodically considered to provide •
the cash flow necessary during peak construction periods.

• Staff is recommending that the WMP be updated every ten years to review
accomplishments, expenditures and projected needs and make any necessary
adjustments to the program, which could include deferral of projects, bond issuance or
increased contributions to maintain the program.

Executive Summary
Introduction
In 1997, the City of Newport Beach Public Works Department Utilities
Division contracted with Boyle Engineering Corporation for
preparation of a Water System Master Plan and Water /Sewer Financial
Plan. The study was undertaken to enable the City to plan, fund and
prioritize future capital improvements by:
0
• Updating and calibrating the City's water system model using the
EPANET model and data handling techniques compatible with the
City's GIS system. Note that the City has recently added HZONET
graphical interface to the EPANET model.. •
• Evaluating the ability to serve present and future water demands
under peak hour and various fire flow conditions using either City
wellfield or imported water sources.
• Identifying and integrating water system improvements for
hydraulic capacity, system reliability, operations enhancement, and
replacement of aging facilities such as piping.
An appurtenant effort is development of a financial plan to enable the
City to establish appropriate rates /fee structures to fund the necessary
water and sewer system improvements. The financial plan is a
separate document.
Transmission and Distribution System Analysis
Piping
The City's water distribution system provides service for an
approximate 13.5 square mile area including the future potential
annexation of the Banning Tract. A total of approximately 600 acres
•
OCN03fiDU-0O gWNB MP EXSCZ f d= Es -t 93OWLE
• of the City is served by the bordering agencies of Irvine Ranch Water
District and Mesa Consolidated Water District (see Figure 1 -1).
The water distribution system is divided into five major pressure
zones, which are further divided into 17 minor pressure zones, serving
elevations from sea level up to elevation 725 feet. The system is
comprised of about 150 miles of water lines.
Model Analysis: The updated water system model includes over 1,000
pipes, totaling about 150 miles in length, as well as 3 reservoirs, 4
pump stations and 36 pressure reducing valves. System piping size
ranges from 4 inches to 48 inches in diameter, with the majority of the
piping in the 8- to 12 -inch diameter range. Variations of the interior
smoothness for unlined steel and cast -iron piping were accounted for
based upon the age of the piping. The hydraulic network model was
developed to analyze the system's ability to meet demands under
specific conditions. The model was calibrated to simulate conditions
measured in the field during May and June 1997, and was successful
within less than 10% variation at all test points (see Section 5).
Deficiencies in the system were determined based upon peak hour and
maximum day plus fire flow conditions with projected ultimate
demands. Based on a study of the City's land use plan and current and
future large water users, the current average daily demand rate of
11,100 gpm is expected to show a modest increase to just over
12,200 gpm at ultimate development within the next 10 to 15 years.
City staff identified 25 points and flows deemed critical for fire flow
service, which were simulated via eight fire flow scenarios.
Transmission and Distribution System Deficiencies: Based on the
analysis, several hydraulic deficiencies were noted and improvements
identified to remedy those requiring attention.
Figure 7 -1 shows the location for each hydraulic system improvement
recommendation with an accompanying numbered tag that
corresponds to the items in Table 7 -1 and Table 7 -2, Part A and Part B
(Distribution) projects. Table 7 -1 gives descriptions, justifications,
modeling comments and estimated construction and capital project
costs for each improvement in 1998 dollars. Table 7 -2 summarizes
capital costs projected to the time of construction.
These improvements remedy only those deficiencies of the peak hour,
summer maximum day plus fire flow, and ultimate demand conditions
GCS 03e00mia WBMP EaecSu .A c ES -2 13OWLE
for the backbone water system identified for modeling by the City. •
During the modeling process, areas in the water system that were
deficient in meeting fire flow demands were noted.
Transmission System Reliability Projects: The Part A projects mainly
improve reliability in the distribution system, while the Part B projects
address specific distribution system deficiencies. Project Al improves
the transmission of Big Canyon Reservoir water to the Corona Del
Mar area. Instead of routing water through distant transmission mains
in San Joaquin Hills, Jamboree, and East Coast Highway, Big Canyon
water is served directly to the southern tip of the city through a
proposed 24 -inch main in Marguerite. As a result, this improvement
will help to boost system pressure in the Corona Del Mar area during
peak hour.
Based upon an internal review of system reliability, the City has also
determined that the Irvine Avenue improvement should be extended
south from Santiago Road to Dover Drive in 24 -inch diameter as well
as along Dover Drive to Westcliff Drive. Should the pipe bridges
along PCH fail during a seismic event, water from the 16i° Street Pump
Station will still be able to reach the eastern end of the system by
rerouting water around Newport Bay along Irvine Avenue. This •
review also resulted in the recommendation for a further extension of
12 -inch piping along Irvine Avenue from Dover Drive to Sherington.
These improvements will improve the reliability of the backbone
system linking the coastal portion of Zone 2 with the portion north of
Dover Drive. Another Part A project related to water supply and
delivery is the recommended construction of two new wells and
appurtenant facilities. This project is estimated to be implemented in
years 2012 and 2013.
Part A and B projects have an estimated capital cost of $10,044,000 in
1998 dollars, which includes two future wells and connecting pipeline
for about $2.8 million.
Pipeline Replacement Program: City staff has developed a 50 -year
pipeline replacement program for cast iron and steel piping built in the
1920s, `30s and `40s, and plans to replace approximately 88,000 linear
feet of these aging mains through 2020. New piping diameters will
match that of the old pipe, except where the old pipe was less than 8-
inches in diameter, in which case 8 -inch piping is to be provided.
Table 7 -2, Part C "Programmed Pipeline Replacements ". summarizes
project locations, costs and proposed year of construction for these
•
oc.No3400.ovq-rN8WMPE sS,Aw ES -3 130VLE
• facilities through 2020. The Appendix provides tables summarizing the
exact street location of each project and lengths of construction
therein. Part C projects total $23,191,000 (1998 dollars) through 2020.
(See Exhibit B in jacket insert of this report.)
Corrosion Assessment of Water Supply Sources
As part of this Water Master Plan effort, an assessment was made by
McGuire Environmental Consultants, Inc., of the implications of
introducing a new source of water into the system. This was done in
advance of startup of the City's new wellfield. A corrosion indices
model was employed to compute indices for the imported water,
groundwater, and blended water sources. All water problems and
degradation of cement -based materials were also analyzed. The study
concludes that the differences in water quality between the primary
supply and blended groundwater are not expected to accelerate
degradation of cement -based materials or ferrous in the City's system.
The final report is contained in the Appendix.
Reservoir Storage
• The City is in a unique position in terms of storage, having within its
service area a large open storage reservoir, Big Canyon Reservoir, at
nearly 600 acre feet capacity or approximately 196 million gallons.
For water quality protection, the City intends to install a floating
(hypalon) cover early in its capital improvement program.
•
Total storage capacity (assuming Big Canyon Reservoir is at its
average operating level and that San Juaoquin Reservoir is not
available) is 102.3 MG. Of this storage, the City reserves a regulatory
storage volume equivalent to about 25 percent of the maximum day
demand (8 MG), plus 3.7 million gallons fire storage for a total of
11.7 MG. The City thus has approximately 90 MG of storage which
can be considered emergency storage. Under the ultimate average day
demand of 17.7 mgd, this represents 5.2 days of storage, which is more
than the 1 to 3 days' volume typically found in Southern California
water agencies. Note that the available volume could nearly be
doubled if the Big Canyon Reservoir operating water surface elevation
were raised by 14 feet. The City normally operates the reservoir at no
greater than 286 feet elevation, but once a cover is installed, the
emergency reserve will be increased. This indicates that the City has
adequate storage, due to Big Canyon Reservoir. However, the ability
oc.rrossaomrq.MHe P E..Sum_dX ES-4 00VLE
to pump water from Big Canyon Reservoir to higher zones must be •
maintained at all times, which is the subject of upgrade
recommendations in the following sections.
The City intends to implement nearly $5 million in upgrades for the
Big Canyon Reservoir including a floating cover and disinfection
system modifications, to be constructed over the next 4 years. The
City has also identified the need for $1,470,000 in miscellaneous
reservoir improvements. through 2020. Refer to Table 7 -2, Part F for
the schedule and costs of these items.
Pump Stations/Zone Transfer Capacity
The analysis in (Chapter 6) of the City's ability to reliably transfer
water to the higher pressure Zones 3, 4 and 5, concludes that the
Zone 3 booster pumping station requires replacement of one existing
150 horsepower pump (2,700 gpm) and motor with a 300 horsepower
pump (5,600 gpm) and motor, along with an additional
300 horsepower pump and motor. This would also require an upgrade
of the electrical service for that pumping station.
The analysis also concludes that the City's plan to install emergency •
power generation capability for the Zone 3 Booster Pumping Station
should be pursued, along with purchase of a portable engine generator
set for emergency use at the Zone 5 booster pumping station. Zone 4
has an existing 1,500 gpm gas driven pump.
It is fiuther concluded that energy savings warrant installation of
VFDs at the Booster Pump Station to Zone 3, and at the Zone 5
Booster Pump Station.
The above improvements are estimated to cost approximately
$769,000 and all but the Zone 5 VFD are recommended for
implementation within the next two years. The City has further
identified $1,950,000 in overall maintenance upgrades for its pumping
facilities through 2020 (in 1998 dollars). Refer to Table 7 -2, Part D,
for the individual schedule and costs for these items.
Variable Speed Pumping
Currently, the City's booster pumping stations maintain constant
discharge pressures by utilizing the pump control valves in a pressure
reducing mode, thereby wasting pump head and electrical energy. An
oc-NOS 600-WgWINB nr EKecs=.dm ES -5 BOYLE
• analysis of installing variable frequency drive equipment to reduce
energy use indicates that approximately $45,000, could be saved
annually at Booster Pumping Station 3, for a capital cost of $85,000.
The investment would pay back in 2 years.
For Booster Pumping Station 5, the comparable annual savings is
estimated at $5,500, for a capital expenditure of $25,000. The payback
timeframe for this station would be 5 years.
Reservoir Fill
A volumetric analysis of the system under ultimate maximum month
demand conditions indicates that imported water deliveries will be
required to supplement the 16th Street/Wellfreld supply in order to
replenish storage in Big Canyon Reservoir. This situation could also
be remedied by additional wells and groundwater delivery capacity, as
discussed in Section 6.
Pressure Reducing Station Upgrades
The City has identified a variety of vault, piping and electrical
• upgrades required at 1 I of its pressure reducing stations, phased over
the next 10 years, to be followed by general non - specific upgrades
which will need to be performed in the subsequent 11 year period. The
most substantial of these projects are the rebuilding of the Bayside
Drive and Bayside/Marina PRS within the next two years. Table 7 -2,
Part E presents a summary of these projects. Part E projects total
$2,270,000 in 1998 dollars.
