LaBelle Utilities System
Use Permit and Well Services
LaBelle Utilities System (PLUS) seeks a SFWMD consumptive water use permit (CUP)
for 1.2 mgd from the Sandstone Aquifer to supply a water treatment plant (WTP)
currently under constructions and scheduled for completion in April 2007.
PLUS is currently supplied by two Sandstone Aquifer wells located on the
site of the WTP, approximately 200 feet apart. PLUS seeks consulting services to
assist in securing the water use permit by April 2007.
Four separate tasks are envisioned: an Aquifer Performance Test (APT),
development of a drawdown impact model, preparation and submittal of a
modification to CUP #26-00096-W, and design and construction of a new proposed
production well at or near the WTP.
will provide access to both wells (PW1 and PW2) so that either a pressure
transducer or a water level indicator can get into the production casing to
measure water levels. It is proposed to pump PW2 and monitor PW1 and any other
wells that can be found in the area.
In-situ data logger will be installed in both production wells (if possible) and
any other wells that can be used. It is proposed to pump well PW2 at a constant
rate of at least 500 gpm (0.72 mgd) for three full days or until a steady state
is achieved. The data loggers will be installed and background water level data
will be collected from all wells for at least 3 days prior to test start. For
the drawdown and recovery tests, the data logger will be programmed to take
water level readings every 0.005 minute logarithmically until 10 minutes is
reached, and then readings will be recorded every 10 minutes until test
water quality data will be taken from well PW2 at the beginning of the test,
after 24 hours and just before the termination of the test. The water will be
tested for chlorides, temperature, specific conductance, and pH.
will be discharged into the storage tank and/or an adjacent lake or the WTP
surface water drainage system.
termination of the pump test, recovery water level data will be collected for 4
data will be analyzed using a programming system acceptable to SFWMD permitting
staff. A report will be written
that will include the following:
Geologic and hydrogeologic conditions at the site,
Description of all wells used as observation wells,
Description of the procedures used to run the constant rate discharge
Description of the data analysis, and appropriate figures.
2: Impact Model
the aquifer parameter data from the APT (or previously determine aquifer
parameter data), an analytical model will be used to run 90-day no recharge
model can reflect current existing users of the Sandstone Aquifer and any other
aquifers potentially impacted by the PLUS extractions.
The modeling task will be used to help determine:
Effects of proposed withdrawals on the Sandstone Aquifer.
The best location for the third production well (PW3).
Effects on other regional users of the Sandstone Aquifer
Effects on other local aquifers, if applicable.
on District rules, an individual model with the proposed withdrawals by PLUS
will first be modeled. A second
model must be run to include all legal existing users of the Sandstone Aquifer
within the projected one-foot drawdown contour line of the individual model run. An impact analysis report will be written to include a
discussion of the model used and the results.
3: SFWMD Permitting
this task, the above information will be used as support for a request for the
1.2 mgd CUP and to add a third production well for PLUS. The initial services
for this task should include:
Attend one meeting with owner, project manager, and/or project engineer
to discuss project objectives, if needed.
Acquire project CAD drawings from the project engineer that shows the
PLUS will provide the necessary population projection to substantiate the
Prepare all necessary graphics.
submit an application and supplemental forms for a SFWMD water use permit, CUP.
Respond to one
letter from SFWMD Staff requesting additional information.
project with PLUS and SFWMD.
4: Well Design and Construction
third well (PW3) will be designed and constructed using all the available data.
The task will include the following services:
Assist PLUS in the preparation and submission of any required permits and
applications to DEP
Prepare well specifications and contract well driller.
Oversee construction of the well and pump system.
Assist and verify that the construction process meets all terms of
Coordinate with well driller, pump installer, and PLUS.
Prepare report on well construction and pump installation.
task will be invoiced on a lump sum basis. Tasks 1, 2, and 4 will be invoiced
upon completion of the task, with Task 3 being invoice upon submittal of the
water use application. The cost of
each task are as outlined below:
1: Aquifer Performance Test
2: Impact Model
3: SFWMD Permitting
Task 4: Well Design and Construction ______________________
