AND MAINTENANCE OF THE ELLIS CREEK WATER RECYCLING FACILITY AND
MAINTAIN REGULATORY COMPLIANCE
1. RECOMMENDATION:
The proposed collaboration of City personnel and Carollo Engineers will result in a well written,
thoroughly documented, and cost-effective manual for operation and maintenance of the Ellis
Creek Water Recycling Facility. This approach ensures the personnel responsible for operating
the facility benefit from the expertise, knowledge and insight of the people who designed the
facility. City Staff recommends the City Council approve the resolution authorizing the City
Manager to execute a professional design services agreement with Carollo Engineers to prepare
Volume 1 — Operations and Maintenance Manual and Complete Volume 2 — Standard Operating
Procedures in support of operation and maintenance of the Ellis Creel: Water Recycling Facility
and maintain regulatory compliance.
2. BACKGROUND:
Written documentation is required to describe how the Ellis Creek Water Recycling Facility is to
be operated and maintained. This documentation is critical for plant start-up and testing,
educating, guiding and informing current and future operations and maintenance staff, and to
providing a historical archive of the design and operation of the facility. It is also required by the
City's National Pollutant Discharge Elimination System (NPDES) permit for operation of the
facility (Section F Provisions, 47). The permit states specifically, "For any significant changes
in treatment facility equipment or operation practices, applicable revisions shall be completed
within 90 days of completion of such changes." The documentation will comprise detailed
narrative descriptions, schematics, and drawings, and will address every aspect of the facility,

The documentation will comprise a suite of operations and maintenance related manuals divided
into the following volumes:
• Volume 1 — Operations and Maintenance Manual (O&M). The O&M Manual addresses
how the individual processes and equipment are designed to achieve treatment of the
community's wastewater.
N
• Volume 2 — Standard Operating Procedures (SOPS). SOPS are prescriptive, detailed and
specific instructions on how to operate the facility.
• Volume 3 — Maintenance Management System. This section will describe the computer-
based maintenance management system and vendor supplied equipment information.
• Volume 4 — Control Descriptions/Supervisory Control and Data Acquisition System
(SCADA). This section describes alarms, troubleshooting and computerized control and
monitoring of the facility.
Volume 3 — Maintenance Management System, and Volume 4 — Control
Descriptions/Supervisory Control and Data Acquisition System (SCADA) are being prepared by
the City and ArcSine Engineering, and are being used now to support startup of the facility. This
agenda report addresses preparation of Volume I — Operations and Maintenance Manual, and
Volume 2 — Standard Operating Procedures.
The cost to prepare Volume 2 — Standard Operating Procedures was originally estimated at
$596,010. This estimate assumed all of the work would be completed by a consultant. The City
decided to take a more collaborative approach to save costs and ensure a higher level of
involvement by City staff. The collaborative effort includes using City staff where possible and
available, to supplement the expertise of the design consultant.
With the addition of the Operations Supervisor and a Lead Water Recycling Plant Operator this
summer, the City now has two new staff people, along with the Engineering Manager, available
to support the consultant in preparation of the SOPS and O&M manual, which helps reduce costs.
It also provides a rare opportunity for these individuals to play an important role in the
docimientation of the plant. The expertise, detail and insight depicted in Volume 1 - Operations
and Maintenance Manual requires the design engineer to translate the intention of the design into
an English language document that can be used by operating personnel. Drawings and computer
simulations of the design are best translated by the original design team. This role cannot be
provided by City staff. Additionally, City staff has been preparing the record drawings for the
Ellis Creek Water Recycling Facility with some oversight from the design engineer and
constriction manager since construction began in October 2005. The same personnel will
supplement the O&M/SOP team and help prepare the schematics and drawings for the manuals
that can easily be read and interpreted by the operating team. This too will save costs.
In August the City initiated a pilot effort for development of Volume 2 — Standard Operating
Procedures to test the collaborative approach for preparation of this document. The strategic use
of available City operations staff resources to supplement the expertise of the design engineer,
Carollo Engineers, has proven successful. As an example for City Council review, a copy of the
draft SOP for the Urban Recycled Water System is provided in Attachment A. We are now
ready to proceed with completion of this document and Volume I — O&M Manual using City
staff resources to supplement the expertise of Carollo Engineers.
Volume 1— O&M Manual
The O&M Manual will consist of approximately 52 sections ranging from the Headworks
Section, which will discuss operation and maintenance of the headworks, where wastewater first
enters the facility, to the Screw Press Section, which will discuss the equipment used to remove
water from the biosolids before it is trucked offsite for beneficial uses. The information provided
in each of the 52 sections will include:
• General Operations Description — a basic description of the process operations goal.
• Design Criteria — a listing of the design criteria tables.
• Component Equipment Listing — tables of important equipment for a given process.
This usually includes electrically powered equipment, instruments, and important
mechanical components.
• Process Control Strategy — description of how to control the process; perform required
calculations, and normal settings for plant specific processes.
Carollo Engineers' proposal for Volume I — O&M Manual is provided in Attachment B. Carollo
Engineers' team includes individuals that originally designed the facility, including Doug Wing,
Christine Gharagozian, Courtney Eaton, Becky Daugherty and Paul Kwong. This approach
boosts efficiency since these individuals are already familiar with the facility and don't need to
waste time learning about how the facility is operated. The estimated cost to complete Volume 1
is $163,479, and assumes the City will perform all the drafting. Drafting for O&M Manuals is
typically performed by the consultant. Using City staff to perform the drafting will save an
estimated $15,000.
Volume 2 — Standard Operating Procedures
The SOPS will also comprise approximately 52 sections. The SOPS are very prescriptive, and
will address startup and normal operation of the equipment and/or process, power outage, and
shutdown and/or cleaning. Carollo Engineers' proposal for Volume 2 — SOPs is provided in
Attachment C. The estimated cost to complete the SOP effort is $143,706, and is based on City -
staff performing the drafting, reviewing procedures, finalizing procedures, training subordinate
team members and testing the operating team. Using City staff for various components of this
work will provide substantial savings for the City.
3. DISCUSSION:
The proposed collaboration of City personnel and Carollo Engineers will result in a well written.
thoroughly documented, and cost-effective manual for operation and maintenance of the Ellis
Creek Water Recycling Facility. This approach ensures the personnel responsible for operating
the facility benefit from the expertise, knowledge and insight of the people who designed the
facility. The document will meet regulatory requirements as stipulated in the NPDES permit.
4. FINANCIAL IMPACTS:
Volume 1— Operations and Maintenance Manual
The cost to prepare Volume 1 of the O&M Manual is $163,479 plus a requested contingency of
$10,000 for a total of $173,479. The budget for this work is $200,000 in cost center 6600-
66100-54140.
b
Volume 2 Standard Operating Procedures
This past spring the City commissioned the new outfall system at the ponds. At that time the
Standard Operating Procedures for the ponds and the new outfall system were developed, tested,
and training provided to the contract operating staff by Carollo Engineers. The total cost to
commission the facility, develop the SOPS and train the contract operating team for operation of
the new outfall system was $140,500.
In preparation for startup and commissioning of the Ellis Creel: Water Recycling Facility, the
City received a proposal from Carollo Engineers to prepare the Standard Operating Procedures
for the remainder of the facility, provide plant commissioning services, and operator training.
The cost of this June 2008 proposal was $596,010. To utilize the talent the City has hired, the
City piloted a team approach to begin development of Volume 2 - Standard Operating
Procedures for the headworks, secondary system, tertiary system, urban recycled water, and
preliminary work on the utilities. The engineering cost to develop these procedures along with
the required regulatory startup plan and initial plant commissioning activities was $141,500. To
finish Volume 2 - Standard Operating Procedures and continue with the team approach piloted in
late summer and early fall, the cost for Carollo Engineers will be $143,706. Hence, the total
expenditure by the City to complete Volume 2 - Standard Operating Procedures, plant facility
commissioning work and training by Carollo is anticipated to be $285,206, with a requested
contingency of $10,000, for a total amount of $295,206. Compared to the proposed amount of
$596,010, the City's collaborative approach yields a savings of $300,804. As illustrated in
Table 1, the total expenditure anticipated for this fiscal year of $295,206 is below the budget of
$300,000. The amount requested in this staff report to Complete Volume 2 — Standard Operating
Procedures is $143,706 plus $10,000 for a total of $153,706.

Urban Recycled Water Chapter
Overview
Introduction The Urban Recycled Water (URW) system is designed to store and pump
reclaimed water for on site use as 3W and off site to customers mostly for
irrigation. The design capacity of the 3W pump station is 3600 gpm at 350 ft
TDH, which is adequate flow and pressure to supply on site demands and
average irrigation demands. Peak irrigation flow will be supplemented by a
future reclaimed water storage reservoir in the distribution system that will
drain during peak irrigation times and refill during low flow periods of the day.
Figure 1 shows the layout of the URW system.

Section
General The safety guidelines for each process and major pieces of equipment are
safety not intended to supersede or supplement existing City safety policies and
procedures. When emergency, abnormal, or alarmed operating conditions
occur, only fix the problem or shutdown if it can be accomplished safely. If it
is not possible to correct a problem safely with available equipment, and
immediate action is required to prevent an illegal discharge or to protect
equipment, the operator should notify the Supervisor and obtain the
necessary assistance and equipment to safely correct the problem. The
established facility safety procedures should be observed during all
operations, including operation under abnormal or emergency conditions.
Electrical The electrical switchgear should be off limits to all but qualified personnel to
safety prevent anyone from making accidental contact. While work is being
performed on any mechanical equipment, its power source should be locked
out and all safety procedures should be followed. All power tools should be
adequately grounded to prevent shock. All electrically driven equipment
having either remote or automatic controls should have signs attached
stating that the equipment may start at any time. Only qualified personnel
should perform electrical maintenance and repairs.

Onsite Storage Section
Overview
Introduction On site open top Reclaimed Water Storage Basin (RWSB) located next to
the Operations Building provides a reservoir to pump reclaimed water to the
distribution system and on site 3W system for use as irrigation or industrial
water supply. The reservoir is normally filled with the reclaimed water from
the tertiary filters and UV system. If the tertiary treatment process is
shutdown there is a backup potable water supply through the 12 inch
motorized 1W valve. Figure 2 shows the URW site layout and pipe
connections to the Reclaimed Water Storage Basin (RWSB).

Recycled Water Storage Basin Normal Operation SOP
Introduction The reservoir has a top to bottom volume of 1.8 MG. Normally the recycled
water storage basin level is allowed to fluctuate based on the time of day
according to normal system demands. Tertiary treatment flow setpoint should
be adjusted as needed or weekly so that the basin will fluctuate between a
low level of 7.2 it (1.0 MG) when daily irrigation is mostly complete at 6 am to
a high level of 9.5 ft (1.5 MG) in the late afternoon before evening irrigation
starts. Overflow is at level 10.5 ft (1.7 MG) (17.0 it elevation) and the top of
levee wall is 1.2 ft higher than the overflow. Required fire water storage
reserves 0.5 MG of that useable capacity.

1W valve The following procedure describes the manual operation of the 1W fill valve
operation used to supply water during emergencies, or when the tertiary process is
shutdown. The water distribution department may also use the valve to flush
aged potable water out of the distribution system to improve water quality in
this section of the City. If distribution flushing is scheduled, the "flush air gap
tank" procedure in the Water Utilities chapter should be completed as soon
as this is completed to improve the water quality on site. In automatic, the
1W valve opens and closes to maintain minimum water level in the reservoir.

URW Pump Station Normal Operation SOP
Introduction The urban reclaimed water (URW) system pumps are designed to pump
reclaimed water from the on site reservoir out to distribution users or the off-
site storage reservoir. Each pump discharges through an automatic strainer
to remove particles in the water that could affect down stream irrigation.

URW service normally operates in Level Control mode in which the
reclaimed water pumps are started and stopped based on the off site URW
distribution system reservoir. When the off site reservoir is at a low level a
URW pump starts to supply water to the tank. URW service in Pressure
Control mode is used when the off site reservoir is not available for
operation, or when the reservoir is full. In this mode of control the URW pump
No. 2, which has a VFD, is started and stopped based on header pressure.

Hydro -pneumatic Tank SOP
Introduction The surge tank or hydro -pneumatic provides a compressible air pad that acts
as a shock absorber when one of the URW pumps starts or stops, which
eliminates the pressure spike on the URW header. When a pump starts the
sudden flow of water will cause higher pressure in the header and fill the
hydro -pneumatic tank causing the air pad to compress. The compressed air
dampens the pressure shock wave, which prevents a water hammer. When a
pump shutdown down the opposite happens, the loss of flow and pressure is
made up by the hydro -pneumatic tank when the compressed air forces water
out of the tank.

Pressure Regulating Valves SOP
Introduction The pressure regulating valves provides a method for the same pump station
to deliver water to multiple locations at different pressure. The URW pumps
are capable of delivering water at a pressure that is too high for all three
possible uses of reclaimed water. There are no electrical controls on the
PRVs, the valves operate by hydraulic pilots from the pipelines they regulate.
The valves should be adjusted annually or when the water systems are not
functioning well.

Urban Recycled Water Distribution System Operations
Section
Overview
Introduction Urban Recycled Water Distribution System carries reclaimed water from the
Ellis Creek pump station to uses throughout the City of Petaluma. Operating
the system requires management of water level in the on-site and distribution

Introduction The distribution system reservoir provides storage of reclaimed water
between 280 and 310 ft of elevation. This provides x.x MG of reclaimed
water from the tank to customers at between 120 and 130 psi. The reservoir
has no controls or mechanical equipment, so setpoints are adjusted
seasonally to manage the volume of stored water and water quality.
Normal The following procedure describes the operating set points to use during low
operation flow season for reclaimed water in winter.
