Sec. 45-20.2. Sanitary sewer service charge.
There is hereby imposed, upon all premises within the city connected to or using the
facilities of the city's sanitary sewer system, a monthly sanitary sewer service
charge. Such sanitary sewer service charge shall be in an amount equal to two
dollars and fourteen seventy-four cents per thousand gallons of water delivered to
the consumer as shown by the water bills rendered in accordance with this Chapter.
The sanitary sewer service charge shall be applied to all accounts based upon
billings rendered meterrerathrrgs on or after October 3, 1994 June 1. 1995. The
amount of such sanitary sewer service charge shall be shown as a separate item
on such water bills and shall be paid by the owner, tenant or occupant in
possession of such premises at the same time and in the same manner as is
provided in this chapter for the payment of water bills. The sanitary sewer service
charge imposed hereby shall become effective upon the expiration of thirty days'
written notice thereof to each and every owner affected thereby as provided herein.
Provided, however, that the customer may file (between October 1, and September
30, of each year) an affidavit on the form prescribed by the City, stating that water
was used regularly for sprinkling or for other purposes that did not enter the system
during the preceding fiscal year October 1, through September 30). Upon
verification by a representative of the City, the customer shall receive a credit equal
to six percent of the total amount of sanitary sewer service charges paid by the
customer during the preceding year. Further provided, that the provisions of this
section shall not be applicable to any water sold and delivered through separate
meters measuring water delivered and consumed solely for swimming pools, lawn
sprinkler systems or other purposes not requiring the use of sanitary sewer system
facilities of the City.

Subject: Water and Sewer Renovation Project and Rate Increase
Administrative Recommendation
The Administration recommends that the Mayor and City Commission hold a public hearing
and adopt this ordinance on second reading.
Description of the System
The City of Miami Beach owns, operates and maintains the potable water system which
serves the residents of the City. The water system in the City of Miami Beach consists of 157
miles of water mains ranging from 6 inches in diameter to 36 inches in diameter. Over 50%
of these lines have been in service for over 40 years. The system contains five water booster
pump stations with a sixth station planned for Terminal Island and four welded steel ground
storage tanks. The system contains 958 fire hydrants, 622 fire lines and has over 23,000
valves of various sizes. These are 11,415 service connections which are all metered.
Because the City is located on a barrier island surrounded by salt water, it was not
AGENDA
ITEM R' -D
DATE 5 -I '1 -95
practicable or economical for the City to develop its own water supply system. The least
costly and highest quality water in the area comes from the Biscayne Aquifer located on the
mainland from wells owned and operated by the Dade County Water and Sewer Department.
The water service to the City comes from four large diameter pipes located on each of the
causeways. Each of the pipes are metered and the City is billed for the water passing through
the four pipes at wholesale rates.
The City also owns, maintains and operates the sewer collection system in the City. The
system consists of 152 miles of lines, including gravity sewers and pressurized force mains.
In addition there are 23 wastewater pump stations. The sewer system is connected to the
Central District wastewater treatment plant located on Virginia Key by way of a subaqueous
54 inch force main under Government Cut. The flow from this line is metered and is the
basis for the charge to the City from Dade county for sewer treatment.
Description of the Project
The City's consultants, Camp Dresser & McKee, have examined the water system and
recommend five categories of improvements for the system. These five categories are: (1)
upgrading of the five existing water booster pump stations and the construction of a sixth
water booster pump station on the Terminal Island; (2) rehabilitation or replacement of the
four water ground storage tanks; (3)miscellaneous water mains replacements and extensions;
(4)replacement of approximately 82,600 feet of undersized galvanized iron water pipe; and
(5) cleaning and cement lining a conservatively estimated length of 335,000 of unlined 6 and
8 inch cast iron pipe.
(1) Two of the water booster pump stations are designed to transfer water from the four
ground storage facilities at 25th Street and 75th Street. The other three existing booster
stations on Belle Isle, 41st Street and Normandy Isle are designed to transfer water from the
supply lines on the Venetian Causeway, Julia Tuttle Causeway and the 79th Street Causeway
into the supply network. The addition of the sixth booster pump station (currently under
design) on Terminal Island will provide the 15 pumps in these stations with a theoretical
capacity which is well above the maximum high range day demand of 46 million gallons per
day even with the capacity reserve for fire suppression of 6,000 gallons per minute.
(2) Two of the ground storage water tanks are located at the 25th Street Public Works
Yard and the other two tanks are located at the 75th Street booster pump station. The two
tanks at the 75th Street location have a capacity of 4.6 million gallons each and are 40 and
45 years old. The two tanks at the 25th Street location have capacities of 3.2 and 4.6 million
gallons and were in existence prior to 1947, each with an estimated age of over 50 years. All
of these tanks with a total capacity of 17 million gallons are of welded steel and would
require approximately$700,000 each to sandblast and repaint due to the fact that the existing
paint is lead based and is now considered a hazardous waste.New prestressed concrete water
storage tanks which require lower maintenance costs can be built for slightly more than the
cost of repairing the existing the over 40 year old tanks currently in service. The proposed
project will replace all four of these tanks.
(3) The project will replace all of the undersized 6 inch water mains south of 5th Street,
extend the 8 inch water main to the Sunset Islands, replace the main at Normandy Drive and
Bay Drive, install new interconnects on the 24 inch main in Dickens and Bryon Avenues,
replace the main in Island Avenue on Belle Isle, extend the main in Bay Road, extend the
main in Drexel Avenue and extend the water mains in the Lincoln Road area. These projects
are necessary to insure water quality, pressure and fire flow.
(4) This portion of the project will replace the estimated 82,600 feet of galvanized iron
water mains that were installed in the 1950's and 1960's with ductile iron lined water pipe
which is the state of the art for Miami Beach conditions. This project will be spread over a
five year period in approximately equal amounts in order to minimize the amount of ditching
that will be required in any one area in any one year.
(5) The project will clean and cement line approximately 335,000 feet of unlined cast iron
and ductile iron pipe. This project can be accomplished without major excavation and will
be accomplished without any major disruption in traffic flow. In addition to restoring a free
flow through these pipes, this project will also repair any line breaks that are causing potable
water to leak from the system. The estimates of lost potable water due to leaks is 9 percent
of the total water purchased which is approximately$750,000 in lost revenue at current rates.
The improvements recommended for the sewer system are to improve the sewer pump
stations and to improve the gravity collection system to reduce infiltration (leakage from
ground water) into the system. The improvements to the pump stations are mainly to raise
the electrical equipment above the 100 year flood level in stainless steel cases. In a few of
the stations this will require the construction of new buildings to house the electrical
transformers or emergency generators. These buildings are being designed by Benard
Zyscovish in order to insure compatibility with the surrounding neighborhoods.
The improvements to the gravity sewers are being prioritized to the areas with the most
infiltration into the sewer system. As all of the ground water that enters the sewer system
costs the City and its residents for its treatment, those areas that have been identified as
having the greatest amount of infiltration will be repaired first. It is anticipated that after the
first two years of this program, the amount of infiltration will be reduced from 8 million
gallons per day to 3 million gallons per day. The estimates are that this first phase will
reduce the operational cost of the sewer system by $2 million annually by reducing the
amount sent to Dade County for treatment with the further elimination estimated to reduce
an additional $1 million annually when the repair program is completed.
The City of Miami Beach will issue water and sewer revenue bonds to undertake renovation
of this scale. The consulting engineers for the City has estimated that the entire project will
cost $95 million which will be accomplished over 5 years. This project will upgrade the
sewer pump stations, clean and reline the water supply pipe network citywide and repair the
sewer system to stop infiltration into the system. The repairs will have the effect of reducing
the operating costs of the system. The actual amount of these savings are difficult to
accurately project at this time; however, the cost savings may exceed $3 million annually
at the completion of the project. These savings will come in the form of reduced payments
to Miami-Dade Water and Sewer Department from whom we purchase water and pay to
treat our sewerage.
Project Costs Effect on Water and Sewer Rates
The rate adjustment that is proposed will have an overall effect of adjusting rates 15 percent
effective June 1, 1995.. Included in that adjustment is the projected 20%rate increase that
Dade County is anticipated to enact effective October 1, 1995. Approximately 60%of the
operational expenses of the Water and Sewer system is the payment to Miami-Dade WASD
which translates their 20%rate increase into a 12%passthrough adjustment to our customers
if implemented on October 1, 1995. By instituting this rate adjustment at this time, the
amount of this passthrough adjustment can be reduced to 9%. To properly fund the capital
projects enumerated above a 6% adjustment with an effective 9%rate adjustment coming
from Dade County is necessary. The Administration proposes that the City only adjust rates
annually and we do not intend to come back to the Commission in October, 1995 for an
additional rate increase unless Dade County imposes an additional surcharge for landfill
closure costs as has been discussed previously in relation to the Ojus settlement.
The City's consultants have also reviewed the metered water and sewer rates in the system
and recommended a rate adjustment to provide for the debt service costs for the first phase
of this project estimated to begin this summer. This rate adjustment also provides for the
anticipated rate adjustment that will be enacted by Dade County with an effective date of
October 1, 1995. By implementing this rate adjustment at this time, the City will be able to
mitigate the amount of the rate adjustment and not have to propose another adjustment until
1996.
Water and Sewer Impact Fees
Another aspect of this proposed rate ordinance is the imposition of water and sewer impact
fees on new development. The fees will help to mitigate the cost of the increased capacity
in the City's systems because of the new development. Funds received from these impact
fees can only be spent to improve the capacity of the systems and are anticipated to total
approximately $100,000 annually. The impact fee reflects an assessment of$155 for water
and $235 for sewer for a single family home and extends upward based on meter size to a
maximum of$12,400 for water and $18,800 for sewer for an 8 inch meter.
Water Conservation and Public Information
A key ingredient of this program is public awareness of the need to repair the water and
sewer systems and the potential for conservation reducing the financial impact. AdvoKatz
has been retained as a subconsultant to Camp Dresser & McKee to handle this important
element of the project.
Average Customer Bill
The average residential customer in the City consumes 15,000 gallons of water monthly. The
monthly bill that the customer currently receives and the monthly bill that will be rendered
at the new rates are presented below:
ti
Current Rate New Rate Percent Adjustment
Water Charge $19.65 $21.00 6.8%
Sewer Charge 33.45 41.10 22.8%
Sanitation Charge 27.11 27.11 -
Storm Water 2,50 2.50 -
Total Monthly Bill $ 82.71 $91.71 11.8%
As can be seen by this analysis,the average monthly customer bill will be adjusted by $8.00
per month. With the cost reductions anticipated from the project, the City will probably seek
to reduce the anticipated rate adjustments in the future as additional capital needs are meet.
The City's rate adjustments will be minimized as the improvements go on line but the
previously announced average 15%rate adjustments over the next five by Dade County will
have to be passed on to our customers.
Conclusion
The City of Miami Beach has allowed its water and sewer system to deteriorate for many
years. In order to provide adequate water service, continue providing adequate fire protection
and eliminate infiltration into the sewer system this project must be implemented. These
repairs are extensive but will only cost more if put off further. The City is making these
repairs with a cost/benefit analysis in mind. The projects and proposed financing have been
extensively studied by the City's consultants Camp Dresser & McKee, Kimley Horn and
Rachlin Cohen and Holtz as well as the Finance/Capital Improvements Committee. The City
will first correct those problems that save as much as possible so that the total project will
be done with the least financial impact to our customers. For these reasons we recommend
approval of the project and the rate adjustment required to fund the revenue bonds.

CITY OF MIAMI BEACH, FLORIDA
PROBLEMS FACING OUR 70+ YEAR OLD,
CLOGGED, ERODED WATER & SEWER SYSTEMS
Threat No water for weeks if pumps fail
during hurricane
Threat Inadequate fire-flowwater pressure
Threat Raw sewage backup in streets from
overburdened system
Threat Water storage tank failures causing
citywide rationing
Threat Fines for noncompliance with federal
mandates
PLUS WASTEFUL WASTE!!! Nearly $3 million a year
down the drain because clean rain and groundwater
leak into sewage system
ASSURING THE WATER SUPPLY:
OUR HIGHEST PRIORITY
WATER MAINS
• More than half the pipes in Miami Beach's fresh water delivery system are 40 years
or older -- and some are more than 70 years old!
• Certain areas of the city are served by the original 6-inch (undersized) mains
installed in the Fisher-Collins era.
• Because those water mains are too small for today's demands, it is difficult to
maintain water pressure in many areas. The 6-inch pipe will be replaced relieving
the water pressure problem and assuring adequate fire flow.
• Most of the city's 40 year old water mains are made of unlined cast iron pipe and
have developed heavy coatings of mineral deposits which:
• reduce the capacity of the pipe affecting fire flow
• can cause discoloration of the water
• may cause bacterial contamination
• have contributed to pipe wall corrosion leaving them vulnerable to rupture at
any time.
• Wherever feasible, mineral buildups will be purged and pipes will be re-lined with
cement.
• As much as possible of the pipe relining will be done without major trenching or
disruption to traffic.
• New mains will be installed where pipes are found to be too corroded to be cleaned
and re-lined.
STRENGTHENING WATER BOOSTER PUMPS
• All water pump motors and controls are presently below the ground and vulnerable
to flooding.
• New electrical systems, high efficiency motors and emergency generators will be
installed to assure the system continues to operate under virtually every
circumstance.
• The electrical equipment, pump controls and emergency generators will be located
in above ground buildings.
• A new pump station will be built to assure fire flow pressure in the South Pointe
area.
NEW WATER STORAGE TANKS
• The city's four 50-year-old water tanks are deteriorating and one is on the brink of
failure.
• Failure of one tank would create a citywide demand control problem, possibly
restricting water usage to hotels, businesses, homes.
• Each of the antiquated welded steel tanks will be replaced with a pre-stressed
concrete structure.
2
REDUCING WASTEFUL SEWAGE TREATMENT:
STOP POURING MONEY DOWN THE DRAIN
• Nearly 170 miles of sanitary sewer (wastewater) pipes transport sewage from all parts of Miami
Beach to the county wastewater treatment plant on Virginia Key.
• Most of Miami Beach's sewers are over 50 years old, and because of the high water table, most
are below water level.
• Our system is so old and fragile that sewers have deteriorated in many places, allowing rainfall
and groundwater to flood into the sewage system. This is known as inflow/infiltration. (See
diagram.)
• Those leaks add nearly 8 million gallons a day to our wastewater system increasing its volume by
almost one-third: WE ARE PAYING NEARLY $3 MILLION A YEAR TO TREAT ABOUT 8
MILLION GALLONS A DAY OF RAINWATER OR GROUNDWATER AS SEWAGE!
• When groundwater seeps into the sewer system, it carries dirt along with it which builds up in the
pipes. Enough buildup and we have blockage which can force raw sewage into our streets.
• Consultants have used two methods to identify the worst areas of infiltration/inflow.
• Smoke testing -- They set off smoke devices in various parts of the sanitary sewer system. If
smoke rises from storm drains, there is strong evidence of improper cross connections that need
to be closed.
• Visual examination -- They drive video cameras into the sanitary sewer system to observe water
leaking into the pipes from cracks or outworn joints.
• Only the most cost effective repairs will be done on the system to remedy about 75% of the
problem.
• Lots of repairs can be done by relining existing pipes without digging them up.
• Reducing infiltration/inflow will also put Miami Beach in compliance with federal guidelines and
help the city avoid EPA penalties.
• Repairs considered to be the highest priority and costing about$25 million will be funded by the
Series 1995 revenue bond issue. The bonds will be financed through modest increases in the
city's water and sewer rates.
SAFEGUARDING OUR SEWAGE SYSTEM:
FORTIFYING THE PUMPS
• At many of the city's wastewater pump stations, motors, electrical equipment and generators are
antiquated and need to be replaced.
• Many of the pump stations have electrical equipment including emergency generators below the
surface and unprotected from flooding in severe weather or hurricanes.
• New pumps, high efficiency motors, electrical systems and emergency generators need to be
installed at the city's major wastewater pump stations.
• At several pump stations, new electrical equipment will be installed above ground and housed in
stainless steel cabinets wherever possible. These stations will also have new landscaping.
• At the largest pumping stations, electrical equipment and generators will be housed in new
buildings to be designed by architect Bernard Zyscovich and his firm, known for work in Miami
Beach. These structures will conform with the city's design guidelines and complement their
neighborhoods.
• Telemetry systems will also be installed to monitor pumps and alert authorities in the event of an
emergency.
• The improvements to these major wastewater pump stations will cost about $12 million and will be
funded by the Series 1995 bond issue.

THE MOST FREQUENTLY ASKED QUESTIONS
ABOUT NEW WATER AND SEWER RATES
• What's wrong with Miami Beach's water & sewer systems?
Parts of our city's 70 year old water and sewer systems are severely clogged and eroded.
Your health isn't endangered at this moment, but electrical components, piping
segments and storage tanks could fail at any time leaving areas of the city without
service for weeks or longer.
Right now we are pouring nearly $3 million a year down the drain because relatively
clean rain and groundwater infiltrate our sewage system. This increases the volume we
send to Metro-Dade for treatment by close to a third. As a result, we are paying Dade
County to treat clean water!
Other serious deficiencies include the risk of inadequate fire flow water pressure, raw
sewage backups in our streets and water storage tank failures that would cause citywide
rationing. On top of that, we face the threat of fines for non-compliance with federal
mandates.
• What will be fixed?
There are three kinds of pipe systems under our streets and they're all in need of major
renovations or replacement • Sanitary sewer (wastewater) pipes will be replaced or
repaired, new pumps, motors, electrical systems and generators will be installed • Fresh
water mains will be enlarged where necessary for fire flow, pipes will be replaced or
repaired, water tanks will be replaced and pumps fortified with new motors and generators
• Stormwater system pipes are also in need of repairs, drainage basins need to be added
so the city is in compliance with federal standards for pollution control. Wastewater and
fresh water system improvements are the first priority. Stormwater system improvements
are slated for later phases.
• Can't we wait a little longer or do a little less
so our rates won't be increased so much?
The threats to our water and sewer systems are real and getting worse. With an out of
sight, out of mind attitude, neglect has put us in this predicament. Engineering experts
make it clear: fixing parts of the systems after failures will be much more expensive
than getting to them before they fail or burst!
Hurricane Andrew sounded a very clear wake up call to Miami Beach. Our city has taken
a hard look at what it will take to get Miami Beach in shape. In addition, priorities have
been set in order to spread the costs over several years rather than doing it all at once.
It's a no frills program that has to be done to keep essential services functioning.
4
MOST FREQUENTLY ASKED QUESTIONS ABOUT NEW WATER AND SEWER RATES, continued
• Will the street near my home or business be torn up. and will I be
without water for a time?
Technology makes it possible to do some repairs to water and sewer lines without tearing
up the street. Whenever possible water mains and sewer pipes will be cleaned and
relined but in many places pipes will have to be replaced.
Engineers estimate traffic disruptions at any given location will be over within a week.
Once in a while, a small area may be without water for only an hour or two. Every effort
will be made to give advance notice for traffic or water disruptions.
Project coordinators will work to avoid major disruptions during large events such as the
Boat Show. Every effort will be made to avoid scheduling major work near tourist
destinations during the height of the season. Undoubtedly, each of us will be
inconvenienced at one time or another but coordinators will work to keep that to a
minimum.
• Why aren't we having a referendum on this?
These improvements are being financed by revenue bonds backed by the water and
sewer user fees we pay the city. Only general obligation bonds backed by special
assessments require referendums. Raising user fees is not the sort of thing our city
commissioners take lightly. They've studied the consultants' reports from top to bottom
and discussed the major points at several committee meetings. They've mounted an
ongoing initiative to find outside funding sources to lower the impact on Miami Beach
property owners. In then end, they've done what we elected them to do... they've made
the tough decisions.
• How will we pay for all this?
The city will issue revenue bonds backed by increased water and sewer charges. The
total bill (including waste and stormwater charges) for a typical home that consumes
about 15,000 gallons of water a month will go from $82.71 to $91.71, an increase of $9
or about 11%.
• Can Metro-Dade County impose additional water and sewer rate
increases on Miami Beach property owners?
Historically, the rates our city pays Metro-Dade to buy water and process sewage have
gone up nearly every year for the past 10 years. Two-thirds of the rate just approved by
our city commission will cover pass throughs from Metro-Dade.
• When will the rate increase be reflected in our bills?
Probably by June, 1995.

City of Miami Beach, Florida
TECHNICAL SUMMARY
1995 WATER AND SEWER IMPROVEMENTS
DESCRIPTION OF THE SYSTEMS
The City of Miami Beach owns, operates and maintains the potable water system which serves
the residents of the City. The water system in the City of Miami Beach consists of 157 miles of
water mains ranging from 6 inches in diameter to 36 inches in diameter. Over 50% of these
lines have been in service for over 40 years. The system contains five water booster pump
stations with a sixth station planned for Terminal Island and four welded steel ground storage
tanks. The system contains 958 fire hydrants, 622 fire lines and has over 23,000 valves of
various sizes. There are 11,415 service connections which are all metered.
Because the City is located on a barrier island surrounded by salt water, it was not practicable
or economical for the City to develop its own water supply system. The least costly and highest
quality water in the area comes from the Biscayne Aquifer located on the mainland from wells
owned and operated by the Dade County Water and Sewer Department (WASAD). The water
service to the City comes from four large diameter pipes located on each of the causeways.
Each of the pipes is metered and the City is billed for the water passing through the four pipes
at wholesale rates.
The City also owns, maintains and operates the sewer collection system in the City. The system
consists of 152 miles of lines, including gravity sewers and pressurized force mains. In addition
there are 23 wastewater pump stations. The sewer system is connected to the Central District
wastewater treatment plan located on Virginia Key by way of a subaqueous 54 inch force main
under Government Cut. The flow from this line is metered and is the basis for the charge to the
City from Dade County for sewer treatment.
DESCRIPTION OF THE PROJECTS
Fresh Water System
The City's consultants, Camp Dresser & McKee, have examined the water system and
recommend five categories of improvements for the system. These five categories are:
1) Water booster pumps - upgrading of the five existing water booster pump stations
and the construction of a sixth water booster pump station on the Terminal Island
2) Water tanks - rehabilitation or replacement of the four water ground storage tanks
3) Water mains - miscellaneous replacements and extensions
4) Water pipe replacement - of approximately 15 miles of undersized galvanized iron
water pipe
5)Water pipe cleaning and cement lining- improvements to a conservatively estimated
length of 63 miles of unlined 6 and 8 inch cast iron pipe.
1
1) Water booster pumps
Two of the water booster pump stations are designed to transfer water from the four ground
storage facilities at 25th Street and 75th Street. The other three existing booster stations on
Belle Isle, 41st Street and Normandy Isle are designed to transfer water from the supply lines
on the Venetian Causeway, Julia Tuttle Causeway and the 79th Street Causeway into the supply
network. The addition of the sixth booster pump station (currently under design) on Terminal
Island will provide the 15 pumps in these stations with a theoretical capacity which is well above
the maximum high range day demand of 46 million gallons per day even with the capacity
reserve for fire suppression of 6,000 gallons per minute.
2) Water tanks
Two of the ground storage water tanks are located at the 25th Street Public Works Yard and the
other two tanks are located at the 75th Street booster pump station. The two tanks at the 75th
Street location have a capacity of 4.6 million gallons each and are 40 and 45 years old. The
two tanks at the 25th Street location have capacities of 3.2 and 4.6 million gallons and were in
existence prior to 1947, each with an estimated age of over 50 years. All of these tanks with
a total capacity of 17 million gallons are of welded steel and would require approximately
$700,000 each to sandblast and repaint due to the fact that the existing paint is lead based and
sandblast residue would be considered a hazardous waste. New prestressed concrete water
storage tanks which require lower maintenance costs can be built for slightly more than the cost
of repairing the existing over 40 year old tanks currently in service. The proposed project will
replace all four of these tanks.
3) Water mains
The project will replace all of the undersized 6 inch water mains south of 5th Street, extend the
8 inch water main to the Sunset Islands, replace the main at Normandy Drive and Bay Drive,
install new interconnects on the 24 inch main in Dickens and Byron Avenues, replace the main
in Island Avenue on Belle Isle, extend the main in Bay Road, extend the main in Drexel Avenue
and extend the water mains in the Lincoln Road area. These projects are necessary to insure
water quality, pressure and fire flow.
4) Water pipe cleaning and cement lining
This portion of the project will replace the estimated 15 miles of galvanized iron water mains that
were installed in the 1950s and 1960s with ductile iron lined water pipe which is the state of the
art for Miami Beach conditions. This project will be spread over a five year period in
approximately equal amounts in order to minimize the amount of ditching that will be required
in any one area in any one year.
5) Water pipe cleaning
The project will clean and cement line approximately 63 miles of unlined cast iron and ductile
iron pipe. This project can be accomplished without major excavation and will be accomplished
without any major disruption in traffic flow. In addition to restoring a free flow through these
pipes, this project will also repair any line breaks that are causing potable water to leak from the
system. The estimates of lost potable water due to leaks is 9 percent of the total water
purchased which is approximately $750,000 in lost revenue at current rates.
2
Sewer (Wastewater) System
The improvements recommended for the sewer system are to improve the sewer pump stations and
to improve the gravity collection system to reduce infiltration (leakage from groundwater) into the
system. The improvements to the pump stations are mainly to raise the electrical equipment above
the 100 year flood level in stainless steel cases. In a few of the stations this will require the
construction of new buildings to house the electrical transformers or emergency generators. These
buildings are being designed by Bernard Zyscovich in order to insure compatibility with the surrounding
neighborhoods.
The improvements to the gravity sewers are being prioritized to the areas with the most infiltration into
the sewer system. As all of the groundwater that enters the sewer system costs the City and its
residents for its treatment, those areas that have been identified as having the greatest amount of
infiltration will be repaired first. It is anticipated that after the first two years of this program, the
amount of infiltration will be reduced from 8 million gallons per day to 3 million gallons per day. The
estimates are that this first phase will reduce the operational cost of the sewer system by $2 million
annually by reducing the amount sent to Dade County for treatment with the further elimination
estimated to reduce an additional $1 million annually when the repair program is completed.
PAYING FOR THE PROJECTS
The City of Miami Beach is issuing water and sewer revenue bonds to undertake renovation of this
scale. The consulting engineers for the City have estimated that the entire project will cost$95 million
which will be accomplished over 5 years. The project will upgrade the sewer pump stations, clean and
reline the water supply network citywide and repair the sewer system to stop infiltration into the
system. The repairs will have the effect of reducing the operating costs of the system. The actual
amount of these savings is difficult to accurately project at this time; however, the cost savings may
exceed $3 million annually at the completion of the project. These savings will come in the form of
reduced payments to WASAD for purchasing water and treatment of our sewerage.
Project Costs Effect on Water and Sewer Rates
The rate adjustment that is proposed will have an overall effect of adjusting rates 16% effective June
1, 1995. Included in that adjustment is the projected 20% rate increase that Dade County is
anticipated to enact effective October 1, 1995. Approximately 62%of the operational expenses of the
water and sewer system is the payment to WASAD which translates their 20% rate increase into a
12% passthrough adjustment to our customers if implemented on October 1, 1995. By instituting this
rate adjustment at this time, the amount of this passthrough adjustment can be reduced to 9%. To
properly fund the capital projects enumerated above a 6% adjustment with an effective 9% rate
adjustment coming from Dade County is necessary. The Administration proposes that the City only
adjust rates annually and the City does not intend to come back to the Commission in October, 1995
for an additional rate increase unless Dade County imposes an additional surcharge for landfill closure
costs as has been discussed previously in relation to the Ojus settlement.
The City's consultants have also reviewed the metered water and sewer rates in the system and
recommended a rate adjustment to provide for the debt service costs for the first phase of this project
estimated to begin this summer. This rate adjustment also provides for the anticipated rate adjustment
that will be enacted by Dade County with an effective date of October 1, 1995. By implementing this
rate adjustment at this time the City will be able to mitigate the amount of the rate adjustment and not
have to propose another adjustment until 1996.
3
Water and Sewer Impact Fees
Another aspect of this proposed rate ordinance is the imposition of water and sewer impact fees
on new development. The fees will help to mitigate the cost of the increased capacity in the
City's systems because of the new development. Funds received from these impact fees can
only be spent to improve the capacity of the systems and are anticipated to total approximately
$100,000 annually. The impact fee reflects an assessment of $155 for water and $235 for sewer
for a single family home and extends upward based on meter size to a maximum of $12,400 for
water and $18,800 for sewer for an 8 inch meter.
Water Conservation and Public Information
A key ingredient of this program is public awareness of the need to repair the water and sewer
systems and the potential for conservation to reduce the financial impact. Advokatz, Inc. has
been retained as a subconsultant to Camp Dresser & McKee to handle this important element
of the project.
Average Customer Bill
The average residential customer in the City consumes 15,000 gallons of water monthly. The
monthly bill that the customer currently receives and the monthly bill that will be rendered at the
new rates are presented below:
AVERAGE MONTHLY WATER AND SEWER CHARGES
Current Rate New Rate Percent Adjustment
Water Charge $19.65 $21.00 6.8%
Sewer Charge 33.45 41.10 22.8%
Total W&S only 53.10 62.10 16.9%
TOTAL MONTHLY CHARGES ON AVERAGE MIAMI BEACH UTILITY BILL
Current Rate New Rate Percent Adjustment
Total W&S 53.10 62.10 16.9%
Waste 27.11 27.11 Unchanged
Storm water 2.50 2.50 Unchanged
TOTAL MONTHLY $82.71 $91.71 10.8%
Conclusion
The City of Miami Beach has allowed its water and sewer system to deteriorate for many years.
In order to provide adequate water service, continue providing adequate fire protection and
eliminate infiltration into the sewer system these projects must be implemented. These repairs
are extensive but will only cost more if put off further. The City is making these repairs with a
cost/benefit analysis in mind. The projects and proposed financing have been extensively
studied by the City's consultants Camp Dresser & McKee, Kimley-Horn and Rachlin Cohen &
Holtz, as well as the Finance/Capital Improvements Committee. The City will first correct those
problems that save as much as possible so that all the projects will be completed with the least
financial impact to our customers. For these reasons we recommend approval of the projects
and the rate adjustment required to fund the revenue bonds.
