GENERAL MANAGER'S RECOMMENDATION
Approve an increase in contingency for the Professional Consultant Services
Agreement with Butier Engineering for construction management services for Newport
Trunk Sewer and Force Mains, Bitter Point Pump Station to Coast Trunk Sewer,
Contract No. 5-58, for an additional $72,437 (4%) contingency, increasing the total
contingency to $181,093 (10%).
SUMMARY
This project will provide a new point of connection from the proposed new Bitter Point
Pump Station to convey the wastewater from the Cities of Newport Beach and Costa
Mesa into Plant No. 2. The existing force main system has failed, requiring emergency
repairs. In addition, the existing system is not suitable for the new operating pressure
from the proposed Bitter Point Pump Station.
Butier Engineering, Inc. is providing construction management services on this project
to support the specialty nature of the construction work. Due to an extension of the
project construction schedule for repairs due to ground settlement, and claims support,
staff has determined that the contingency budget of 6% is inadequate, and request
additional contingency of $72,437 (4%), for a total contingency of $181 ,093 (10%).
PRIOR COMMITTEE/BOARD ACTIONS

GENERAL MANAGER'S RECOMMENDATION
1. Approve a Professional Design Services Agreement with Brown and Caldwell for
Santa Ana Trunk Sewer Rehabilitation, Project No. 1-17, providing for engineering
design services for an amount not to exceed $801,850; and,
2. Approve a contingency of $80,185 (10%).
SUMMARY
The proposed Professional Design Services Agreement (PDSA) includes the condition
assessment of the existing trunk sewer and manholes. Other elements include
preparation of plan and profile drawings, flow monitoring, hydraulic modeling, odor
monitoring and mitigation, rehabilitation recommendations, and project delivery
analysis.
A Request for Proposal was sent to seven firms and seven proposals were received.
Based on the overall qualifications and expertise, staff recommends awarding a PDSA
to Brown and Caldwell for a total fee not to exceed $801,850.
PRIOR COMMITTEE/BOARD ACTIONS
None.
ADDITIONAL INFORMATION
The Santa Ana Trunk Sewer was constructed in 1952 and is located in the cities of
Costa Mesa, Santa Ana, and Fountain Valley. The upstream end of the Santa Ana
Trunk Sewer begins at the intersection of Alton Avenue and Bristol Street in Santa Ana
and the downstream end discharges into the Orange County Sanitation District
(Sanitation District) Plant No. 1 in Fountain Valley. The sewer is primarily within the
Alton Avenue right-of-way; however, there are segments within Ellis Avenue, Orange
County Flood Control (including the Santa Ana River), 405 freeway, railroad right-of-way
and Costa Mesa's Business District. The pipe consists of approximately 5,600 linear
feet of 42-inch and 11,700 linear feet of 48-inch diameter unlined reinforced concrete
pipe. The portion under the 405 freeway consists of 450 linear feet of 60-inch lined
reinforced concrete pipe.
Form No.DW-102 Revised: 01/11/10
Page 1
The reinforced concrete pipe is in various stages of deterioration. The Santa Ana Trunk
Sewer Inspection Report published in January 2002 identified several major defects
such as pipeline corrosion, ground water infiltration, exposed aggregate, intrusion of
roots and concrete erosion. The crown of the pipeline exhibited the most severe
corrosion with infiltration at various locations primarily due to joint separation
accompanied by root intrusion and/or mineral like deposits. The 60-inch lined pipeline
under the 405 freeway has bubbles or disbanding in the lining and needs thorough
inspection.
The intent of this project is to identify the sewer's condition and provide the most cost
effective rehabilitation.
Staff Evaluation of Proposals
A panel consisting of four members of the Sanitation District's staff reviewed and ranked
each of the proposals in accordance with Resolution No. OCSD 07-04, Section 5.07.
The proposals were evaluated in the following six equally weighted categories: project
approach and understanding of the scope of work, plan for managing and performing
the work, staff qualifications, related experience, team organization and use of sub-
consultants, and quality assurance/quality control plan. Staff also conducted interviews
with the top three short-listed firms to meet the key team members and further explore
the firm's proposal. Brown and Caldwell was the top ranked team.
All proposals were accompanied by a sealed fee proposal estimate. The fee proposal
estimates were not opened until the proposals were evaluated and a firm was selected,
in accordance with Resolution No. OCSD 07-04, Section 5.07. Staff recommends
awarding the design contract to Brown and Caldwell.

3) Approve a 15% annual unit price and program price contingency.
SUMMARY
Odor and corrosion control methods are continuously being developed and improved
upon. For this reason, O&M staff monitor industry best practices, evaluate the cost
effectiveness of new methods and technologies, and conduct site-specific field trials for
the odor and corrosion control program based upon changing flows in OCSD's trunk
sewer system. With the approval of this change order, staff will have flexibility to adjust
the program based on the market, trunk line system needs and any future changing
Form No.DW-102.2 Revised: 01/11/2010

regulations, environmental rules, costs or conditions all while maintaining our level of
service of controlling hydrogen sulfide odors to 25 parts per million in headspace and
0.5 part per million of dissolved sulfides in the liquid phase.
The chemical unit prices (in $/gal) include a portion for the product and a portion for
support services. These support services include providing for rental equipment, labor
for on-going corrective and preventative maintenance of the equipment, remote
monitoring of the chemical and feed rates, optimization, and field sampling. OCSD
currently purchases ferrous chloride of 34% weight, and the supplier and manufacturer
have made available the higher product strength of 36% weight. The increase of $0.090
per gallon reflects this higher concentration product, which will enable reduced volumes
for usage and fewer truck deliveries. This unit cost price increase does not reflect an
actual material price increase, just an adjustment for a higher concentration solution. By
increasing the strengths of these chemicals, this will allow OCSD to reduce the overall
program cost resulting in a savings over the contract period. While improving the
program's overall effectiveness, the additional chemical options of ferric chloride, 36%
weight ferrous chloride, and 65% weight calcium nitrate provide OCSD with new options
in the event of supply interruptions and new approaches that may provide an
improvement over existing chemical treatment methods.
An increase of $0.025 per gallon for the magnesium hydroxide product was submitted
through the contract renewal process from OCSD's supplier, Hill Brothers Chemical
Company. This increase is based upon a material product increase from the product
manufacturer. The Contracts and Purchasing Division staff have determined the
proposed cost increase is reasonable. The support services within the contract include
dose site development, system mobilization/demobilization, and equipment rental
services to provide the most expeditious and cost effective treatment approach. This will
allow staff to conduct field trials of alternative treatment methods and to deploy odor and
corrosion control treatment on short-term basis on an as-needed basis.
PRIOR COMMITTEE/BOARD ACTIONS
On May 20, 2009, the Board awarded a contract to U.S. Peroxide, LLC, and to Hill
Brothers Chemical Company for Regional Odor and Corrosion Control Services,
Specification No. C-2009-405BD, and approved a 10% annual unit price contingency.
On February 17, 2010, the General Manager released the 10% contingency for a unit
price increase for ferrous chloride provided by U.S. Peroxide, LLC.
ADDITIONAL INFORMATION
These contracts were formerly bid out as one contract however; the respondents could
not provide all chemicals that OCSD requested. For this reason, there will continue to
be two contracts with two separate companies.
Expanding OCSD's chemical and technology resources will benefit OCSD's ratepayers
by increasing efficiency, allowing flexibility with changing conditions, increasing
Form No.DW-102.2 Revised: 01/11/2010

operational reliability, and reducing cost through the use of new products and less
chemical.
Management of odor and corrosion is a significant part of the services that OCSD
provides to protect public health and the environment and manage its assets properly.
The regional trunk line odor and corrosion control program reduces sulfides associated
with odor generation and structural degradation within the regional trunk sewer lines. In
addition, treatment in the regional trunks provides a secondary benefit of controlling
hydrogen sulfide and odors entering the treatment plants. Newly designed capital
projects at the treatment plants have been designed based upon continuous chemical
treatment for odor control in the regional trunks. These upstream dosing activities are
easily and cost effectively outsourced to turnkey service providers. Staff maintains a
high degree of oversight for these providers with daily interaction at OCSD dosing
facilities as well as program planning and detailed review of all invoices prior to approval
for payment.

CIP Project Manager: Umesh Murthy
GENERAL MANAGER'S RECOMMENDATION
Adopt Resolution No. OCSD 10-XX, A Resolution of the Board of Directors of the
Orange County Sanitation District, Making Findings Pursuant to Public Contract Code
Section 3400 in Support of the Sole Source Specification of Thickening and Dewatering
Centrifuges (Sludge Thickening, Dewatering and Odor Control at Plant 1, Job
No. P1-101).
SUMMARY
Public Contract Code § 3400 allows local agencies to draft bid specifications for public
works that call for a designated product if the awarding authority, or its designee, finds
that the product is designated "in order to obtain a necessary item that is only available
from one source...." An item is available from only one source if there is not an "equal"
product, meaning a product that will "function as well, in all essential respects" as the
designated product. By necessary implication, if only two sources are available for a
product, those two products may be specified to the exclusion of others.
Sludge Thickening, Dewatering and Odor Control at Plant 1, Job No. P1-101, must be
designed around centrifuges selected by the Orange County Sanitation District
(Sanitation District). HDR Engineering, Inc. is preparing the plans and specifications for
the project, for which the construction contract is scheduled to be awarded in December
2011. Based on extensive investigation, Sanitation District staff have determined that
GEA Westfalia Separator, Inc. (Westfalia) manufactures the only centrifuge meeting the
Sanitation District's needs for co-thickening sludge, and Westfalia and Alfa Laval, Inc.
(Alfa Laval) are the only manufacturers of centrifuges meeting the Sanitation District's
needs for dewatering sludge. The estimated cost for the thickening centrifuges (total of
three) is in the range of$6-7.5 million. The estimated cost for the dewatering
centrifuges (total of three) is also in the range of $6-7.5 million.
PRIOR COMMITTEE/BOARD ACTIONS
None.

ADDITIONAL INFORMATION
Need for Centrifuges
Summary of Solids Processing Constraints
Currently, treatment of the influent wastewater generates primary sludge, which has
a solids content of 3% to 5%, and secondary sludge, which has a solids content of
0.15% to 0.6%. The secondary sludge is thickened using dissolved air flotation
thickeners (DAFTs) to about 4% solids. This thickened secondary sludge is blended
with the primary sludge and fed to digesters. Digested biosolids are dewatered
using belt presses to about 19% solids so that it can be trucked for reuse. As part of
its long-range biosolids planning, the Sanitation District considered the following
constraints:
The amount of solids entering Plant No. 1 for processing (the "Plant 1 Load") is
expected to increase from 245,000 pounds per day in 2012 to 306,000 pounds
per day in 2030.
Plant No. 1 will generate much more secondary sludge once new secondary
facilities become operational in 2012.
The Sanitation District's existing dewatering facilities (belt presses) were built in
1982 and 1988 and are reaching the end of their useful life.
As depicted in Attachment "A", the Sanitation District faces severe space-
constraints for new facilities at Plant No.1.
The Proposed Project
Accounting for these constraints, in 2003, the Sanitation District adopted a Long-
Range Biosolids Management Plan recommending centrifuge sludge thickening to
increase digester efficiency (instead of building more digesters for which there is not
space) and centrifuge dewatering to increase the solids content of the Sanitation
District's biosolids, resulting in fewer truck trips to off-site biosolids reuse facilities
(instead of replacing the expiring belt presses). Sludge thickening using centrifuges
will increase the percentage of solids in sludge going to the digesters from the
current 3%-5% to 6-7%. Sludge dewatering using centrifuges will increase the
percentage of solids in the biosolids from the current 19% to 27%-30%. This
increase in biosolids solids content (dryness) will reduce the tonnage of biosolids
generated at Reclamation Plant No. 1.
The Sanitation District Requires Automated Thickening Adjustment Technology
The Sanitation District will combine and co-thicken primary sludge and secondary
waste activated sludge in a centrifuge before digestion, as depicted in Attachment
"B". A centrifuge is roughly analogous to a residential clothes washing machine, in
which clothes are soaked in water and the water is subsequently removed by
spinning. In this case, a dilute influent sludge with relatively low solids content is
Form No.DW-102 Revised: 01/11/10
Page 2
spun in the centrifuge and some of the water in the wastewater stream is removed,
yielding higher solids content in the effluent product. Attachment "C" depicts a cut-
away view of a thickening centrifuge.
In co-thickening, the solids concentration and flow rates of both sludge streams will
vary day-to-day and hour-to-hour. Consequently, the characteristics of the
centrifuge feed sludge will change dynamically. Because of the Sanitation District's
operational needs as a large, "always-on", complex treatment plant, the Sanitation
District's thickening centrifuges must adjust automatically to changes in the sludge
feed rate and solids content, without the need to routinely stop the centrifuge for
manual adjustment. Likewise, because the thickening centrifuges are part of the
treatment process critical path, the Sanitation District must obtain the thickening
centrifuges from a manufacturer experienced in producing centrifuges of the size
required by the Sanitation District with the automated adjustment mechanism. The
Sanitation District's customers cannot risk a critical path failure of the sanitation
system, which would be more likely to result from selection of an inexperienced
manufacturer.
Centrifuge Space and Operational Constraints
As depicted in Attachments "A" and "D", the amount of space available for the
digesters is very constrained. The Sanitation District does not require unique
technology for its dewatering centrifuges for the project, as it does for the thickening
centrifuges. The Sanitation District does, however, require dewatering centrifuges
that can process up to 6,800 Ibs per hour of solids within the Sanitation District's
fundamental physical space constraints. Also, as with the thickening centrifuges, the
Sanitation District must obtain the dewatering centrifuges from a manufacturer
experienced in automated dewatering processes. The Sanitation District cannot risk
using an inexperienced manufacturer.
The Proposed Manufacturers are the Only Source for the Necessary Items
Investigation of Potential Manufacturers
To determine the list of potential manufacturers, the Sanitation District engaged
consultants as part of its design team with decades of experience in the wastewater
centrifuge market. To ensure that their information was current, the team visited the
International Trade Fair for Water, Sewage, Refuse and Recycling and the Water
Environment Federation Conference. These activities resulted in the evaluation of
thickening and dewatering centrifuges available in the market from six
manufacturers: Alfa Laval, Andritz, Centrysis, Flotweg, Siemens, and Westfalia.
Form No.DW-102 Revised: 01/11/10
Page 3
Evaluation Criteria for Thickening Centrifuges, Criteria Application, and Additional
Investigation
Job No. P1-101 has the following necessary characteristics:
1. Co-thickening of primary sludge and waste activated sludge
2. Processing of primary sludge
3. Processing of waste activated sludge
4. Automated dynamic pond control
5. The ability to fit within a relatively small space (which can only be done with
40-inch centrifuge bowls)
6. Documented reliability with automated dynamic pond control when co-thickening
The evaluation of thickening centrifuges centered on these criteria. The table below
shows how the evaluation criteria were applied.
Manufacturer Criteria 1 Criteria 2 Criteria 3 Criteria 4 Criteria 5 Criteria 6
Westfalia ✓ ✓ ✓ ✓ ✓ ✓
Andritz ✓ ✓ ✓ ✓ ✓
Alfa Laval ✓ ✓ ✓
Centrysis ✓ ✓ ✓
Flotweg ✓ ✓ ✓
Siemens ✓ ✓ ✓
In summary, Westfalia is the only manufacturer with a documented record of successful
operation of thickening centrifuges for co-thickening of primary and waste activated
sludge using automated variable pond depth control technology. Sanitation District
consultants contacted and visited manufacturers and operating plants to determine the
extent to which existing facilities were using thickening centrifuges in a manner
consistent with the Sanitation District's needs. The results are as follows:

Andritz
Form No.DW-102 Revised: 01/11/10
Page 4
Because Andritz cannot show any experience with automated controls on thickening
centrifuges used for co-thickening with the capacity required by the Sanitation
District, it cannot establish that its centrifuges perform "as well" as the Westfalia
centrifuges which are recommended to be specified. For reference, when the City of
Los Angeles issued a solicitation for thickening centrifuges for co-thickening using
automated variable pond depth control technology, it required a minimum of two
years of experience at three separate installations. Although Andritz was the low
bidder in response to that solicitation, the City of Los Angeles selected Westfalia
because Andritz could not meet the experience requirement.
Evaluation Criteria for Dewatering Centrifuges and Criteria Application
The evaluation of dewatering centrifuges centered on the following criteria:
1. Whether the combined footprint of the centrifuges needed for capacity could fit
within the limited space available for the centrifuges;
2. The quality of materials used to construct the centrifuges;
3. The manufacturer's experience with automated controls on dewatering
centrifuges with the capacity required by the Sanitation District; and
4. The manufacturer's overall experience in the U.S. market.
The table below shows how the evaluation criteria were applied.
Criteria 1 Criteria 2 Criteria 3 Criteria 4
Manufacturer
Westfalia ✓ ✓ ✓ ✓
Andritz ✓ ✓
Alfa Laval ✓ ✓ ✓ ✓

In summary, Westfalia and Alfa Laval are the only manufacturers with a documented
record of successful operation of automated dewatering centrifuges which fit within the
limited space available for the centrifuges.

CEQA FINDINGS
Pursuant to CEQA Guidelines section 15352, the recommended actions are not
approvals requiring environmental review under CEQA because the recommended
actions are only to make findings sufficient to allow the Sanitation District to designate
specified equipment in the construction contract for Job No. P1-101 . The
recommended actions do not commit the Sanitation District to a definite course of action
to let a contract for bidding, to award a contract, or to authorize any contractor to
proceed to construct Job No. P1-101.
Pursuant to CEQA Guidelines section 15168(c)(4), Project P1-101 will be examined in
the light of the following program Environmental Impact Report (EIR) to determine
whether an additional environmental document must be prepared: Sanitation District's
Strategic Plan Program EIR certified in October 1999, as supplemented by the
Subsequent Environmental Impact Report for the Secondary Treatment and Plan
Improvement Project, dated March 2005. Specifically, the Sanitation District will use a
written checklist or similar device to document the evaluation of the Project site and
Job No. P1-101 to determine whether the environmental effects of Job No. P1-101 were
covered in the program EIR.
BUDGET/DELEGATION OF AUTHORITY COMPLIANCE
This action complies with authority levels of the Sanitation District's Delegation of
Authority. No additional funds are requested with this action. This item has been
budgeted (FY 2010-11 Budget: Job P1-101 Line Item) and the budget is sufficient for
the recommended action.

GENERAL MANAGER'S RECOMMENDATION
Authorize staff to negotiate Amendment No. 2 to the Professional Design Services
Agreement with Malcolm Pirnie, Inc. for additional design services for the Newport
Force Main Condition Assessment, Project No. 5-60.
SUMMARY
The scope of Newport Force Main Condition Assessment, Project No. 5-60, is to
perform a condition assessment of the Orange County Sanitation District's (Sanitation
District) network of force main piping in the City of Newport Beach. The condition
assessment was to be done by constructing manholes along Pacific Coast Highway
(PCH) and televising the piping from the inside. The Design Consultant is Malcolm
Pirnie, Inc. (Malcolm Pirnie).
Prior to design and construction of the manholes, staff conducted preliminary
investigations of the piping. The findings revealed greater than anticipated deterioration
of the network piping. This condition is consistent with deteriorated piping observed
recently on the Bayside Drive Improvement Project at the same vicinity. Staff has
determined that the force main piping along PCH in Newport Beach is in need of
rehabilitation.
Staff is recommending that no further work be done on the condition assessment and to
move forward with the rehabilitation of the piping. Moving directly to design of the
rehabilitation will reduce risk of piping failure, reduce traffic closure impact on PCH, and
reduce redundant bypass pumping. The budget for this work was included in the
Capital Improvement Program (CIP) Budget for 2010-11.
Staff is requesting authorization to negotiate an amendment to the Professional Design
Services Agreement (PDSA) with Malcolm Pirnie to add the pipe rehabilitation design to
their existing scope of work. Malcolm Pirnie is qualified to perform the work and the
continuation of services by retaining Malcolm Pirnie will expedite the project design and
reduce project costs.
PRIOR COMMITTEE/BOARD ACTIONS
February, 2009 —Awarded a contract to Malcolm Pirnie Inc., for the professional design
services Newport Force Main Condition Assessment, Project No. 5-60, for an amount of
$1,120,418 and approved a contingency of $112,042 (10%).
Form No.DW-102 Revised: 01/11/10
Page 1
ADDITIONAL INFORMATION
Staff has determined that the force main piping along PCH in Newport Beach is in need
of rehabilitation. This is based on recent Closed Circuit Television (CCTV) inspections
of the force main piping, along with corrosion studies conducted over the past several
years. Rather than continuing with a lengthy and disruptive inspection along PCH, staff
is requesting authorization to negotiate an amendment with Malcolm Pirnie to design
the rehabilitation of the piping system.
The major advantage of moving directly to the design stage is that it reduces the project
to one construction period. This will significantly reduce costs, staffing, risks, schedule,
and impacts to the public. This approach is supported by the City of Newport Beach.
This project could proceed as originally planned, but would prolong the rehabilitation of
a piping system that is known to be in deteriorated conditions.
The request to negotiate an amendment with Malcolm Pirnie rather than issue a new
Request for Proposal (RFP) is based on cost and time savings. Malcolm Pirnie has an
existing contract with design work, and issuing an RFP for a new Consultant would
increase staff labor costs and add 6-9 months to the schedule. Malcolm Pirnie is very
experienced in pipe rehabilitation and is qualified to perform this work.
The original scope of work included design of 12 manholes and a condition assessment
of the Newport Force Main network piping system. The manholes not only gave the
project team access to perform the condition assessment, but also allowed
maintenance access in the future. The proposed scope eliminates the condition
assessment, but adds rehabilitation design for the piping system. The scope for the
manholes remains to allow for liner construction and future maintenance access to the
piping system.
The current PDSA for Malcolm Pirnie is $1,120,418. The estimated value of the
amendment is approximately $1,000,000. After negotiations, staff will request approval
of the amendment by the Board of Directors.

Orange County Sanitation District
FROM: James D. Ruth, General Manager
Originator: Ed Torres, Director of Technical Services
GENERAL MANAGER'S RECOMMENDATION
Authorize an agreement with OpenCEL, LLC, for installation of equipment and onsite
proprietary testing of Plant No. 1 waste activated sludge treatment (Project
No. SP-125-6), for a total amount not to exceed $1,700,000 upon successful installation
and testing as follows:
a) Authorize a turn-key installation of OpenCEL equipment and all necessary
auxiliary equipment and utilities for an amount not to exceed $300,000;
b) Approve a sole source lease purchase of OpenCEL equipment for onsite
proprietary testing for a maximum of 36 months at a cost of $32,000 per month,
and a down payment of $250,000; and,
c) Authorize purchase of the OpenCEL equipment for a total amount not to exceed
$1,400,000 upon successful testing.
SUMMARY
A proprietary process marketed by OpenCEL LLC treats sludge prior to anaerobic
digestion to increase its digestibility, resulting in cost savings from increased digester
gas production and reduced amounts of residual biosolids. Laboratory-scale tests using
OCSD-provided sludge have indicated that the OpenCEL treatment could be effective,
and payback periods of two to three years have been calculated for full installations at
either treatment plant.
A full-scale test of approximately nine months is expected to verify and document the
benefits to OCSD.
The manufacturer will provide and install equipment for OCSD to test under a lease
purchase agreement that can be cancelled at any time by OCSD. The purchase price is
$1,400,000; however, if the agreement is cancelled during the first 18 months of the
agreement, the initial $250,000 down payment and 40% of the monthly lease payments
previously paid will be returned to OCSD.
The net liability to OCSD for a nine-month test, if not purchased, would not exceed
$472,800, which consists of up-to $300,000 for equipment installation plus $172,800
Form No.DW-102.2 Agenda Report—Board
Revised: 09/01/2009
Page 1
(the number of months multiplied by 60% of the monthly lease payments ($32,000 x
60%) totaling $19,200 per month or $172,800 for a nine- month test).
If the equipment is purchased, all payments (monthly and down payment) will be
applied to the purchase price. Permanent installation would be planned and managed
under a separate CIP project.
PRIOR COMMITTEE/BOARD ACTIONS
December 2008 — Received and filed the five-year Research Strategic Plan, which
included the OpenCEL process evaluation as a planned project.
ADDITIONAL INFORMATION
OpenCEL has been used successfully in a full-scale commercial installation at the
wastewater treatment plant in Mesa, AZ, since 2007. Staff is recommending entering
into a lease purchase agreement because the OpenCEL equipment is built to order for
a customer, so no "demonstration" or "rental" units are available for full-scale tests. The
alternative of hiring installation subcontractors directly was considered, but a turn-key
