AGENDA ITEM SUMMARY
Meeting Date: June 10, 2015
Bulk Item: Yes No X
Division: Engineering & Public Works
Department: Wastewater
Staff Contact Person/Phone #:Wilson (453-8797)_
AGENDA ITEM WORDING: Approval expansion of Cudjoe Regional Wastewater system to
include 42 properties on No Name Key and 57 properties on Middle and Big Torch Keys plus 35
additional properties whose cost of service is comparable. Additional funds coming from infrastructure
Sales tax and property assessments.
ITEM BACKGROUND: FKAA recommends inclusion of an additional 99 properties located on No
Name Key, Middle Torch Key and Big Torch Key. They have developed a plan that brings the
average cost per connection for these properties to under $30,000 on No Name Key and under $25,000
for Big & Middle Torch. FKAA has reviewed the remaining properties not included in the CRWS to
identify which can be included for costs similar to NNK & Torches. In the past, the cost breakpoint
used for central service vs. on -site systems has been $22,500. Inclusion of these properties will reduce
the number of on -site systems to approximately 70. Centralized treatment also offers better treatment
than can be achieved in on -site systems. The net additional cost for these expansions will be $2.2
million if only the NNK & Torch Keys are included. The added net cost to include 35 properties on
USL, Summerland, and BPK North is $0.6 million for a total is all expansions are approved of $2.8
million. The highest average unit cost is for NNK at $30k/property. This is the continuation of agenda
item C-33 from the May 2015 BOCC meeting with the addition of 35 properties.

PUBLIC WORKS & ENGINEERING DIVISION
DATE: 25 May 2015
TO: BOCC CC: Administrator
FROM: Kevin G. Wilson
SUBJECT: Expansion of CRWS to NNK, Big & Middle Torch Keys and
35 Properties on BPK North, Upper Sugarloaf, and Summerland (Nile Rd.)
Recommended Action:
Approval of FKAA proposed expansions.
Basis for Recommendation:
1. The costs of inclusion of these properties are all under $30,000/EDU
2. The cost of on -site systems is higher than originally estimated
3. On site systems are proving impractical on small lots
4. The additional properties on USL & BPK North were originally rejected based on
the old breakpoint of $22,500.
Background
In Early May 2015, FKAA proposed to include 99 additional properties on No Name Key
(42 EDUs) and Big Torch & Middle Torch Keys (57 EDUs). The proposal was based on
the fact that these properties were planned to be served with on -site systems which are
proving more expensive and less technically feasible. In many cases the on -site
systems were not feasible because they require more ground space than is available on
many individual lots.
At County request, FKAA reviewed the remaining properties for which on -site systems
were planned to identify any for which the costs of inclusion in CRWS central system
were comparable with the NNK & Big/Middle Torch properties. FKAA identified two
"additive/outreach" areas on Big Pine Key encompassing 23 EDUs that had previously
been rejected for inclusion. The costs for these two areas were above the previous
cutoff but below $25,000/EDU. Three additional outreach areas on Upper Sugarloaf
were identified with per EDU costs below $28,000 were identified. FKAA also identified
8 additional properties on Summerland Keys' Niles Road that it estimates can be
included for under $24,000/EDU. FKAA recommends including these additional 35
properties because the estimated EDU costs are below the costs for NNK.
Approval of the original proposed expansion to NNK, and Big & Middle Torch Keys will
cost $2.69 million of which $0.45 million will come from individual property assessments
and $2.24 million will come from infrastructure sales tax revenues. If the additional 35
properties on BPK North, USL, and Summerland are included the additional required
funding from infrastructure sales tax is $0.6 million. These costs are detailed in the
below table.

AGENDA ITEM #
Date: May 5, 2015
To: Kevin Wilson, Monroe County
From: Tom Walker, FKAA
Subject: Extension of Cudjoe Wastewater Service Area No Name, Middle Torch and Big Torch Keys
The original consideration for providing service to outlying areas required an estimated construction
cost of less than or equal to $22,500 per connection. This cost threshold was based solely on cost
considerations which assumed an on -site treatment system coot:„be built for approximately $22,500
and that central sewers were less than this cost per connection
Since these initial rules of engagement with handling outlying areas weroat in place, many properties
have been brought into the regional service area, based on competitive priei'g;.and locations of these
properties which led to a reduction of more than 100 on -site systems to be bu�.nd maintained. Also,
during this time, FKAA:
• Evaluated remaining properties outside the central=ever area to determine potential
engineering and construction considerations to tie into the central area
• Have conducted the design and permitting of several on -site systems for properties outside the
central sewer area Thi: effort has exposed several challenges to installing compliant on -site
treatment properties with limited spe

Name Key (NNK), Middle Tover Big brt- Keys becaU a of estimated costs to be considerably higher

FKAA recommends that Monroe County add these three islands (42 EDUs on NNK & 57 EDUs on Big &
Middle Torch) into the CRWS. Our recommendation is based on several considerations:
1. CRWS provides a much higher level of wastewater treatment and system reliability than any on -
site system.
2. The DOH -approved on -site systems take a considerably large space (on the order of 400-600
square feet) considering installation on many small, existing properties.
3. With the conversion of many LPS areas to gravity areas, the price point for central sewers has
increased well above the $22,500 per connection in the conversion areas.
4. Property owners would much rather have central sewer services than an on -site system.
Given the approval to proceed, FKAA can have these properties available for central service by October,
2016.

June 10, 2015
Board of County Commissioners,
'Monroe County, FL
Re: June 10, 2015 BOCC Agenda item J1
Greetings:
This is written as a concerned resident of the Cudjoe Regional Wastewater System (CRWS) service area.
The June 10t' BOCC meeting Agenda item "J1" proposes to extend an already overextended sewer
system to collect wastewater from homes that in some cases have no commercial electricity and no
FKAA water. That is Irresponsible at best and here is why:
A. The treatment plant on Cudjoe Key does not have sufficient capacity to treat the total of
expected daily flows from existpermits. To add additional properties Is a violation of 62-
600.405 F.A.C. and increases the near certainty that the plant will be unable to adequately treat
the Incoming wastewater. The DEP expressed in writing that they doubted that the plant was
capable of adequately treating more than 0.84 mgd (million gallons per day) based on their
experience and the sizing of the treatment tanks in Cudjoe. Current collection system permits
total 1,301,537 average gallons per day or 1.3 mgd. Correcting for what appears to be an
obvious engineer's blunder on the Summerland permit, the average daily flow currently.
expected and permitted reduces to 1.07 mgd. See notes 1 and 2 for additional concerns about
inadequate capacity- not only. of the plant but of the entire collection system.
B. If a property does not have commercial power connected, it is highly unlikely that their
alternative power system will be able to handle the very high starting current of an E-One
grinder pump, or any grinder pump for that matter. Published misinformation, reportedly from
FKAA, has supposedly addressed this concern by saying that a 120 volt pump will be used
instead of the 240 volt pump typically used. What they did not say was that the power
consumption and horsepower Is the same for both pumps. So a 120 volt pump must draw twice
the current of a 240 volt pump to produce the same one horsepower (in a perfect world where
losses are identical). That represents an intolerable load for most alternative energy sources.
See (dote 4 for additional concerns.
C. When one is getting all their water from a cistern, conservation is normally imperative.
Consequently, wastewater generation is lower than might be expected elsewhere, and likewise
the potential for nutrient loading is also reduced. FKAA uses an unreasonably high (punitive?)
flat sewer rate for cistern properties (5,300 gals/mo or 174 gpd per FKAA Rules 48-107.007)
since the water is not metered. In other words, they bill for water that Is not likely used and not
likely treated. Hence, their eagerness to connect these properties to central sewer treatment. Is
FKAA about public service and environmental protection or about maximizing profitJike Dow or
Monsanto? The current edition of the Florida Water Resources Journal includes an engineering
report from Hazen and Sawyer Engineering in Tampa where they accomplished AWT by simply
adding a bio-filter to a conventional septic tank. There Is no need for expensive, energy
intensive solutions.
So far as the power situation is concerned, the solution is simple: put the grinder pump in the public
right of way or in the preexisting road and utility easement where they should be. Let FKAA power them
just as they power pumping equipment for every house on conventional gravity or vacuum sewer
collection. If there Is no commercial power in the vicinity, their solution will be interesting. Let's see
how many solar cells and batteries it takes to maintain sewer service through stormy weather.
There are better ways to accomplish nutrient reduction. Notably, none of them require increasing the
sales of E-One grinder pumps.
I strongly recommend that you do not approve further over extension of the CRWS.
Sincerely,
John Prosser
Notes:
1. The plant -was permitted at 0.84 mgd average daily flow based on a draft technical report. Two
days after the permit application was submitted, the final technical report was issued by the
consulting engineers that said to expect 1.06 mgd, but the DEP was riot informed by FKAA of the
final numbers. This was before the addition of numerous "warm and cold spots" to the already
overloaded plant and design changes that are likely to increase infiltration.
2. The permits assumed daily water use for most residences at much lower than the 167 gpd for
one EDU. In northern Little torch, the permit assumed only92 gpd for mobile homes. If the
system is designed to handle less than 1 EDU per home, then why is every dwelling unit paying
for a full EDU? If the character of a neighborhood changes to one of higher use and the system is
designed around an unreasonably low use assumption, then where does the extra sewage go
that was not accommodated in the original design? Also, the permits assumed that all of the
inner islands use 40% of metered water for outside use such as irrigation and car washing, which
Is ridiculous, and that overall about 30% of all CRWS water goes to irrigation which is equally
ridiculous.
3. The technical -memorandum that calculated expected flow from each Island used commercial
EDU values that are in some cases obviously incorrect. For example, one does not need to live
here to know that 1 EDU for a bar and grill is unreasonable. That is especially true for a very
busy bar and grill such as this particular one.
4. A capacitor start motor such as E-One's may be expected to draw 4 to 5 times normal running
current at start-up. It may draw more If it was in the middle of chopping something up when it
last stopped. (The locked -rotor" current draw of a 240 volt E-one grinder is 30.4 amps.)
Pumping clean water against light resistance, the E-One draws about b amps running on 240

that might be providing normal household current from a solar or wind charged battery bank. At
120 volts, the current draw and power surge. Is roughly doubled. Unlike with a conventional
centrifugal -grinder pump where power consumption drops when unable to pump, the positive
displacement E-One just tries harder- increasing both pressure and current draw. If resistance to
pumping is excessive, the motor overheats and trips an internal thermal overload switch. The
switch automatically resets. At 175 psi, the thermal overload switches off and on about every 30
seconds, and the repeated power surges may be expected to destroy a solid state power
inverter. A grinder pump is simply not suitable for a typical alternative power supply. Where the

Board of County Commissioners Meeting
Marathon, Florida
June 10, 2015
Agenda Item J1
Last Stand applauds the BOCC and FKAA for considering the expansion of the Cudjoe Regional
Wastewater system to include 42 properties on No Name Key and 57 properties on Middle and Big
Torch Keys plus additional properties whose cost of service is comparable.
Replacing the use of onsite systems with connections to a well designed centralized wastewater
treatment plant will result in public health and environmental benefits and will certainly move us
forward in achieving our goal of improving nearshore water quality in the Keys.
Over the years, Last Stand has directed special attention to No Name Key. While some homes on No
Name have hooked up to the conventional power grid recently, there are many others that have not.
The water collection and power generation systems of these off -grid homes have been individually
constructed, using a variety of designs and electrical components to provide water and electricity onsite.
A committed group of homeowners on No Name Key fought many years to retain their right to power
their homes using off -the -grid, environmentally -sound solar systems and to maintain the solar
community character that had charmed them in the first place.
We have learned that many of those homeowners, for whom maintenance of this off -the -grid lifestyle is
a matter of great importance, have concerns that their off -the -grid power generating systems would not
be compatible with the E/One grinder installations that are being used throughout the Cudjoe Regional
system.
We believe it's important that their special circumstances be taken into account early in the Cudjoe
system expansion process.
