SUBJECT: RESOLUTION APPROVING AND AUTHORIZING EXECUTION OF AN _
AMENDMENT TO THE AGREEMENT BETWEEN THE CITY OF MIAMI
BEACH AND CAMP DRESSER & MCKEE INC. FOR PROFESSIONAL
SERVICES FOR THE UPGRADE OF SEWER AND WATER PUMPING
STATIONS AND DESIGN OF A NEW WATER PUMPING STATION ON
MACARTHUR CAUSEWAY
ADMINISTRATION RECOMMENDATION:
It is recommended that the City Commission approve a resolution authorizing the Mayor
and the City Clerk to execute the amendment to the agreement between the City of Miami
Beach and Camp Dresser& McKee Inc. for professional services for the upgrade of sewer
and water pumping stations and design of a new water pumping station on MacArthur
Causeway and to approve a resolution to reimburse these funds from a future bond fund.
BACKGROUND
On July 8, 1992, the City Commission passed resolution 92-20540 authorizing the Mayor
and City Clerk to execute an agreement between the City of Miami Beach and Camp
Dresser& McKee Inc..to provide engineering services for upgrading sewer and water pump
stations and design of a new water pump station on the MacArthur Causeway.
The contract documents provide for three phases of work to be accepted and approved
incrementally.
The Phase I preliminary design is completed and in accordance with the contract
documents and the findings of the Phase I report we are in position to start Phase II, the
final design and construction documents.
Staff has reviewed the CDM proposal for Phase II and reduced hours on some proposed
tasks and in some cases added to the scope of work. The overall objective is to develop
a comprehensive set of construction documents which will upgrade the sewer and water
pump stations to a state-of-the-art. In addition to the mechanical upgrades the scope of
• work includes a comprehensive review of structural and aesthetical conditions of the pump
stations and the surrounding sites, a review of safety conditions especially as it may apply
to employees working in the stations at all times of the day and night and most importantly
the state-of-the-art instrumentation which will provide central control of all facilities with
capabilities to develop and provide information which is becoming more and more
important as environmental regulations escalate.

Commission Memorandum Page 2 September 22, 1993
In addition to the project related scope of work, critical issues covered in the contract
include:
• A completion schedule of 180 days from authorization to proceed
from the City.
• Site upgrading and landscaping and safety considerations within the
pump stations were negotiated into the contract at no additional
engineering cost.
• City approval and acceptance of contract documents does not relieve
consultant from any liabilities relative to competency of drawing and
errors or omissions.
• The consultant indemnifies the city harmless with respect to costs,
damages, and liabilities from any negligence or wrongful act or
omission and shall pay all costs including judgement and attorney's
fees which may issue thereon.
• If the lowest bid exceeds the established construction estimate by ten
percent(10%),the City at its sole discretion has the following options:
1) Approve the increased cost;
2) Reject all bids and authorize rebiding;
3) Abandon or terminate contract;
4) Select deductive alternatives to bring award within the
construction budget; or,
5) Reduce size of project to reduce construction cost.
In the event the City chooses to reduce project scope or quality of
project as listed above,the consultant shall provide necessary revisions
to construction documents as may be necessary and provide rebiding
services as many times as requested by the City at no additional cost
to the City until base bid meets the requirements of the contract.
The proposal is the result of extensive negotiations with CDM, and consists of six major
tasks. Staff has reviewed this in depth and find the man hour count very reasonable
especially considering the complexity of the work and considering that the design must
include provision to keep the stations operable at all times during construction. This
almost doubles the requirements as compared to a totally new project. Because of this a
general percent of construction approach is not directly applicable even though the number
is comparable to other engineering projects currently underway.

EXECUTIVE SUMMARY
BACKGROUND AND INTRODUCTION
Project Scope
On July 8, 1992, the City of Miami Beach Commission executed a contract with Camp
Dresser & McKee Inc. (CDM) for engineering services on two projects. The scope of the
first project centers around replacement of the outdated instrumentation and control
equipment in the City's existing water and wastewater pumping stations. The second project
involves a proposed water booster pumping station on MacArthur Causeway. This report
covers the first of these two important endeavors.
As a part of the work effort for this project, CDM met with the City's water and wastewater
system personnel and visited the facilities. The power supply, instrumentation and control
equipment at the stations listed in Table ES-1 was evaluated and recommendations were
made. CDM also reviewed the existing Supervisory Control and Data Acquisition (SCADA)
system to determine how much of the existing system could be incorporated into a new
system. In addition, the existing communications (telephone circuits) system was evaluated
in consideration of the requirements of the new SCADA system.
Existing Situation
The City initiated this project primarily to correct frequent failures in the control system and
to increase the system's overall efficiency. Although many of these stations were updated in
the mid-1970s, the equipment in use is generally not of the most current design and
replacement parts are difficult to obtain for many of the units. In some cases, the original
manufacturers have gone out of business thereby exacerbating the parts availability situation.
Furthermore, the water and wastewater pumping systems have evolved over the years while
not necessarily following a well-defined master plan. Some areas of the system may have
changed in character and land use, thus causing deviations from the original design
assumptions. Flow rates may be much less than planned or in excess of the original design
values. Because of the evolutionary nature of the system and the age of the control
equipment, the pumping stations may not work well with each other, resulting in further
degradation of system efficiency.
The basic design of most of the pumping stations further complicates the situation in that the
stations are primarily constructed below grade with most of the electrical controls located
below ground surface. Hurricane Andrew highlighted the tenuous nature of this system's
operation: if the peak storm surge had occurred at Miami Beach, rather than further south,

many of the pumping stations would have been out of commission for weeks, at great cost
and disruption to daily life in the City. Thus, contingency planning has been incorporated
into the upgrade of this pumping system.
PUMP STATION FACILITY REQUIREMENTS
Pump Flow Rate Control
Pumping system design should incorporate a method of varying flows through the facility
because flows in a water distribution system or a wastewater collection system vary
throughout the day. For instance, sewage flows at night might only be 30 percent'of the
average flow rate, while during the peak hour, flows can be three times the average. Water
systems experience a similar flow variation, resulting in lower pressures at peak flow rates.
To adjust to this phenomenon, designers of pumping stations typically use variable speed
motors or drives to match the speed of the pumping equipment to the instantaneous flow rate,
allowing for smoother, more efficient operation.
Variable Speed Drives
There are many different kinds of variable speed drives available for use with water and
wastewater pumps. Some of these devices incorporate less than current technology, as is the
case with most of the City's current pumping stations. For example, the design of wound
rotor motors incorporates two separate windings. The primary winding or stator is quite
similar to that found in the more familiar, squirrel cage-type motor, but instead of a simple
rotor of metal, this device incorporates a rotor wound with insulated copper wire, also
known as the secondary winding. As the resistance is varied in the secondary winding, the
rotor speed is varied. To vary the rotor resistance, connecting wires must be brought outside
of the motor. To accomplish this requirement and still allow rotation of the rotor, devices
such as slip rings and carbon brushes are utilized. These power transmission devices can be
highly maintenance intensive and inherently rob efficiency.
The motors operated by the City currently use two methods to vary the resistance of the
motor "secondary" windings. The first method is currently used at the water booster
pumping stations and consists of a fixed resistor grid, providing the selection of perhaps two
or three motor speeds. The other method, used at the wastewater pumping stations, involves
a variable liquid rheostat using electrodes suspended in an electrolyte (a solution of sodium
carbonate in distilled water). The electrical resistance of the rheostat varies in relation to the
separation of electrical plates in the device. As the resistance is increased, motor speed is
decreased. Disadvantages of liquid rheostats include messy, leak-prone, electrolyte piping;
failing circulation pumps; poor efficiency; and poor power factor.
As a replacement technology, variable frequency-type, variable speed drives operate
standard squirrel cage induction motors (and in some cases, wound rotor motors). The
principle of operation is based upon varying the input voltage and frequency to an electric
motor by a compact, solid-state electrical component-type device. Major advantages of
•

f A
( i
•
variable frequency drives (VFDs) include operation with standard motors, high reliability,
high efficiency, and high power factor, resulting in reduced operating costs. These drives
are more complex than the less efficient drive types, but the increased efficiency more than
makes up for this drawback.
Pumping System Control
The design of each pumping system includes specialized equipment to control the pump
motors which can be categorized into two broad areas. The first includes all devices
controlling the flow of electrical power to the pump motors, such as transformers, switches,
and motor control centers (MCCs). The second includes all devices that allow operation
personnel to supervise the functioning of the pumping equipment, start and stop pumps, and
change the system control points such as pressure, flow, and wetwell levels.
Motor Control
MCCs usually include one or more motor starters, which are devices that apply electrical
current to the motor in a controlled manner causing,the motor to start and stop. Motor
starters usually consist of a heavy motor- or solenoid-operated switch actuated by "control
power". Control power is usually 120 volts AC, but can be 24 volts DC. The starter can be
relatively simple (just an electrically operated switch) or can include more sophisticated
devices to shut off the motor in the case of a short circuit, loss of power on one or more
phases, or an overload.
When not installed in a controlled environment, MCCs are subject to degradation by
corrosion. MCCs in the City's wastewater pumping stations have shown the effect of
corrosion caused by the "salt air", high humidity, and presence of hydrogen sulfide gas in
the unconditioned air in the stations. Parts for some of the MCCs are no longer available or
are not available from the original manufacturer because, again, many of the original
manufacturers are no longer in the power control business or have ceased doing business,
making replacement and maintenance difficult.
Power Supply Considerations
The water booster pumping stations were originally furnished with a power supply of a
relatively high voltage. Although now commonly referred to as "medium" voltage, the
City's present use of 4,160 volts as a power supply is now normally used only for motors
above 350 horsepower (hp). Due to the age of these power systems and the fact that the
designs do not comply with current codes, the electrical systems must be totally replaced,
and thus a 480-volt power supply is recommended. A power supply using 480 volts will not
only be less expensive from a capital cost perspective, but will allow the use of less
expensive VFDs. When compared at equal horsepower ratings, a 4,160-volt VFD may be
more than twice as expensive as its 480 volt equivalent.
9381-02-RT ES-4
Standby Capability
Wastewater pumping,stations are required by the Florida Department of Environmental
Regulation (FDER) to have standby power capability. This standby capability can be
provided by an emergency connection and portable pumps or portable or permanent standby
generators. Larger pumping stations (stations with discharge force mains sized at 8 inches
and above) are required to have suitable design features to provide reasonable assurances of
uninterrupted flow.
In South Florida, "reasonable assurances" are usually provided by installing dedicated
standby generators. Hurricane Andrew emphasized this need for standby power generation
equipment. Because of the City's proximity to the Atlantic Ocean and vulnerability to storm-
related damages, serious consideration must be given to the selection of dedicated standby
generators for all critical wastewater pumping stations, regardless of discharge force-main
size.
Instrumentation Systems
Instrumentation systems allow operators to control the functioning of water and wastewater
pumping equipment within predetermined ranges. A properly designed, modern control
system should allow for control of pressure and flow rate while maximizing system electrical
efficiency. Furthermore, modern instrumentation systems will provide for complete control
of pumping systems under the most difficult conditions with the least number of operators.
A typical wastewater instrumentation pumping system will include sensors that transmit the
pump station wetwell level to a local control panel at the individual pumping station. The
control panel may be of a hardwired-type using relay logic or it may of`the programmable
logic controller (PLC) design. In either case, the controller starts, varies the speed, and
stops pumps based upon the level in the wetwell.
The controls of a typical water booster pumping station must monitor both downstream and
upstream conditions to ensure that the service area is kept within a prescribed pressure range
while not lowering water pressures in the area from which the station takes its supply.
Similar to the wastewater pumping station, the water booster pump system controller can
again be either of the hardwired or PLC type, with the PLC type being more prevalent in
recent times. The PLC offers the end userr the ability to program the pump station to react to
a number of different conditions without intervention or continuous control by operations
personnel. A PLC type control system can also be programmed to optimize pump station
operation for maximum energy efficiency.
When tied into a Supervisory Control and Data Acqusition (SCADA) system, the operator
can be kept informed of all critical operating conditions in the system such as number of
pumps on line, wetwell levels, or pressures and flows at each station. The operator (or in
some cases, a pre-programmed central processing unit) can remotely adjust system set points
9381-02-RT ES-5
•
so as to maximize efficiency or even indrectly help to control some of the odors generated at
a wastewater pumping station. A typical SCADA system consists of a remote telemetry unit
(RTU), a radio or telephone based transmitter and receiver system, a central processing unit
(CPU), and monitoring and control software. The CPU is normally installed in a central
control facility that is manned on a continuous basis so that error or alarm conditions can be
detected and corrected soon after they occur. A typical control room consists of the CPU,
video monitors, visible or audible alarm annunciators, and report/alarm printers.
ADDITIONAL ISSUES
Not a part of the scope of this project, but discovered during the work effort, were several
additional items that the City should consider to provide a more dependable water and
wastewater pumping system. The scope of this project requires that new variable frequency
drives be designed to replace the existing wound rotor motor secondary controllers at the
wastewater pumping stations listed on Table ES-1. Our investigation has found that the
existing motors may not work properly or may experience failures when operated on a
variable frequency/variable voltage power supply, because those motors were specifically
designed for operation with a variable secondary resistance. To function with a variable
frequency drive, the secondary wound rotor motors will have to be shorted out. The original
motor manufacturers have stated concerns with that mode of operation. If funding is
available, a better approach would be to replace the motors involved with new, high-
efficiency squirrel cage induction type units.
As noted above, our investigation of existing pump station equipment found that the MCCs
in several of the existing wastewater pumping stations are heavily corroded due to inherent
"salt air", high humidities, and the presence of hydrogen sulfide gas. Consideration should
be given to replacing the MCCs at these stations during the installation of the new variable
frequency drives. These MCC units will eventually have to be replaced anyway, and a cost
advantage could be realized with the electrical contractor already mobilized.
The electrical equipment at several of the pumping stations inspected during the course of
our investigations was found to be below the 100-year flood level indicated on the flood
insurance maps published by the Federal Emergency Management Agency (FEMA), and thus
susceptible to costly water damage. As discussed above, current FDER regulations require
that large pumping stations (stations with discharge force mains sized at 8 inches and above)
have suitable design features to provide reasonable assurances of uninterrupted flow. If a
station cannot be "flood-proofed" because of its location or existing design, provisions must
be made to be able to provide reasonable assurances. Since it is not cost-effective nor
possible to truly flood-proof existing facilities, this mandate may result in the City having to
purchase portable engine-driven pumping equipment or install dedicated backup pumping
systems for use during emergencies, thus adding a dimension of "flood-protection".
Our investigations further found that several of the pumping units themselves may require
replacement in the near future. Serious consideration should be given to replacing the pumps
in stations where new VFDs are to be installed. New pumping units can be sized to meet
9381-02-RT ES-6
•
actual and projected flow conditions with maximum efficiency. The internal parts of existing
units are probably worn to a point that pump efficiency is significantly less than that of new
units. In several underground stations, it may be best to install new submersible pumps with
an electrical connection above grade to connect to portable generators and controls, thus
addressing the flood-protection issue and the new pump and new motor recommendation at
the same time.
A hydraulic and cost-effectiveness analysis should be performed for each pumping station to
determine if the provision of new pumping equipment is justified. In combination with an
analysis of required pump station flows, the lowest present worth cost of the total water and
wastewater pumping system could then be achieved.
RECOMMENDATIONS
Based on our investigations, CDM recommends the following:
Instrumentation and Controls
• All existing controls including relays and panelboards on all pumping systems should
be replaced with PLCs in environmentally conditioned cabinets.
• All telemetry communication systems should be replaced with current state-of-the-art
telemetry communication systems.
• New control strategies should be initiated in the PLCs of the water and wastewater
pumping stations. This will enable the pumping systems to smoothly meet and match
the range of demands in the system.
• A new central control room SCADA computer system should be installed and
connected to all pump stations via a new telemetry system. The central computer will
enable operations personnel to more fully manage the water and wastewater pumping
systems.
• New pressure, flow, and level transmitters that are compatible with the new SCADA
and telemetry system should be purchased and installed.
Electrical Recommendations
• All of the liquid rheostat speed controls on the wastewater pumping system should be
replaced with more efficient VFDs and reconnected to the existing motors and MCCs
for operation with the new VFDs. This will enable the control system changes to
succeed.
9381-02-RT ES-7
f
• For wastewater pump stations, existing motors and MCCs should be replaced for
operation with the new VFDs (see above). Enclosure and environmental conditioning
considerations vary among the stations.
• At five of the six water pump stations (the exception being the Shop (Marina) Booster
Station which is to be replaced by a new water booster station at another location),
existing 4,160-volt electrical systems should be replaced with 480-volt services. The
new electrical systems will require standby power capability to meet current state
regulations. Location and elevation considerations vary among the stations.
Additional Work
Beyond the items covered in the project scope of work, there are other additional
improvements that the City should carry out:
• The addition of variable frequency drives at submersible Pump Stations PS2 and PS31
to reduce excessive peak flows and resulting odor complaints.
• Replacement of wound rotor motors at several of the wastewater pump stations.
• Replacement of MCCs at all wastewater pump stations.
• Replacement of all seal water systems at the existing dry pit pumping stations.
• Replacement of the older wastewater pumps at the same time as the wound rotor
motors due to cost saving considerations.
• "Flood-protection" of all stations to some practical degree including the incorporation
of submersible pumps with above grade portable generators and controls.
COSTS AND SCHEDULING
The proposed schedule and the current estimated costs for the basic program in the scope of
work is depicted in Table ES-2. Normally, the payback period for conversion to VFD
controls is on the order of five years, however, considering the operational state of the
existing equipment and current system, the payback period should be less. The schedule and
estimated cost for the additional recommended program is shown in Table ES-3. To best
carry out these additional improvements, the City should first conduct hydraulic analyses of
the water and wastewater systems to verify pump and power requirements. The latter should
include an assessment of the amount of extraneous, rainfall-induced flow (known as
infiltration/inflow, or "I/I") into the wastewater system. The cost of I/I work and hydraulic
analysis, including remedial action to the wastewater pipes, cannot be properly estimated at
this time, and is not included. All costs are estimated in 1993 dollars.

FINANCIAL IMPACT
At a meeting on February 8, 1993, the City Manager requested a "fast track" evaluation of
the impact of the recommended improvements ("base" program plus "additional" program)
on the water and wastewater bills. The results are presented in a letter report dated February
18, 1993, which is included as Appendix F. The simplified analysis, based on an "across the
board" increase concept and on cost figures available at the time, indicated rate increases of
approximately 4 percent and 6 percent for water and wastewater, respectively. The cost
figures have increased slightly since that date, as the City has asked us to refine the
"additional" program with several "new" options, but the resulting rate increases should still
be relatively modest.
CDM recommends that a detailed rate study be conducted later this year to more equitably
allocate both existing and future costs to the City's users (rather than an "across the board"
increase). At that time, opportunities for any federal government assistance to mitigate these
costs should be better known. In any case, design of the improvements should begin soon,
to put the City in a "ready to build" status.
