BOARD OF COUNTY COMMISSIONERS
AGENDA ITEM SUMMARY
Meeting Date: June 18. 2003
Division:
BOCC
Bulk Item: Yes
No~
Department: DISTRICT 5
AGENDA ITEM WORDING:
Discussion and approval of a standardized method of bidding, method of process, method of collection,
and type of materials used for wastewater plants under one million gallons per day in unincorporated
Monroe County.
ITEM BACKGROUND:
Recent studies have shown that design bid projects (7.6.4) receive the best engineering and
construction costs by using industry's expertise to design them. The latest technology in wastewater is
the up flow sludge blanket filtration (or equal) with low operating cost, minimal sludge hauling and low
initial capital costs. The BOCC has adopted by agenda item to use pre-engineered field erected steel
units as recommended by the Wastewater Master Plan (3.7.1). The Wastewater Master Plan
recommends using a vacuum collection system as the most cost effective (3.8.1). A standard for the
bid process, wastewater process, collection system and materials used for wastewater plants should be
adopted by resolution to create a standard throughout the county.

3.8.1 Collection System Construction
Cost Estimates
Total annual collection system costs per
EDU within the study areas ranged from
$154 on Windley Key (Study Area 18) to
$1,595 for Ocean Reef Club (Study Area
27), where houses are relatively far apart.
Densely populated areas typi~ally cost less
per EDU to sewer than less densely popu-
lated areas, but costs were highly site-
specific. As shown in Exhibits 3-37 and
3-38, vacuum collection was typically the
most cost-effective collection alternative
when the number of EDUs being collected
was more than about 350. In 22 of the 27
study areas, vacuum collection was the
lowest cost alternative for serving the
entire study area. Technical Memorandum
No.6 in Volume 4, Supporting Documents,
of this Master Plan, provides a detailed
discussion, evaluation, and cost estimates
for the collection system alternatives.
Besides being the most cost-effective
collection system alternative, vacuum
sewer systems offer the following addi-
tional benefits:
. No electrical power is required at each
home or vacuum valve
. Wastewater collection service is main-
tained during short-term or long-
term utility power outages. A
standby generator tl:1at will auto-
matically generate power if there is
a loss of utility power will be pro-
vided at each vacuum station.
. Air drawn into the vacuum system
with the sewage will help to keep the
sewage fresh, and thus will help to
eliminate odors.

RE: Conch Key, FL
AIRV ACEstimate #20.0.2-110.
Jeff:
Encl9sed is an AIRVAC budget estimate and layout for COnchKey. Also
enclosed is a Technical Report that giv~s.supporting information as well as
technica.l data relating to this estimate.
We obviously are pleased that you are looking .at using vacuum sewe:rs for this
area. However, we do want to give you the benefIt of our experience with
regard to small projects. It has been our experience that vacuf4m is T!i1rely. Gost-
effective for fewer than 1 DO. connections. There are two reaSOJilS forthis. First,
it is difficult to overcome the cost of the vacuum station for very smaUpr{)Je~ts.
Second, the smaller projects typically do not invoJve very much pipe footage.
This'minimizes one of the largest cost savings of using vacuum. ObViously,
none of the jobs in the Keys are "typical", so there may be other f~ctors at work
that will result in vacuum being cost-effective.
A summary of the costs is shown below:

The cost issue aside, this appears to be a goodapplic~tibn for vacuum sewers
for the following reasons:
.. A new vacuum sewer system would provide a superior collection system
to a gravity sewer system. First, the inherent tight nature of vacuum
wouldeltminate the 1/1 problems associat$d with gravity systems.
Second, the shallow installation would make future connections and
repairs much easier than with the deep g~avity sewers. . Finally, odors
wbuld be significantly reduced .since no 'manholes or.ott1er.op~nings
exjs~ within the collecti<?n ,system. . .
· Vacuum would also provide a superior system when compared to low-
pressl,Jre s.ewers utilizing grinder pumps. Power is. only required only at
the vacuum station instead of at every service connection. Standby
power at the vacuum station insures uninterrupted.powerduring power
outages whereas standby power is not practical for every single grinder
pump. Long term O&M should be significantly less especially wh6ln
replacement of grinder pumps at is C?onsidered @ year 10.
If you have any questions or require additional information, please do not
hesitate to call.
