FEE PROPOSAL AND SCOPE OF SERVICES
CITY OF BOYNTON BEACH
SERVICES AT THE WEST WELLFIELD
Backeround
The City of Boynton Beach (City) owns and operates the West Wellfield to provide raw
supply water for the West Water Treatment Plant (WTP). The wellfield consists of both
active and inactive production wells designed to supply the WTP with water from the
surficial aquifer.
The WTP has recently experienced an increase in the amount of sand reaching the
cartridge filters. The increase in sand has resulted in a decrease in cartridge filter working-
Fife and could ultimately damage the treatment membranes.
The City has asked that a study be performed to identify the source of the increase in sand
reaching the WTP. The study will involve an evaluation of instrumentation, raw water
lines, and the supply wells. Sand production at Wells 10W and 12W has been noted and
may be the source of the increase in sand reaching the WTPo Upon identification of the
source of the increased sand, the appropriate modifications to the raw water supply system
will be designed and implemented to reduce sand production.
The City would like to place inactive Wells 4W, 5W, 6W and 13W into service in order to
increase the raw water supply available to the WTP. Wells 4W, 5W, and 6W are
connected to the raw water line; however, 13W will need to be connected to the raw
water line. Modifications to the wellhead may be necessary at Wells 1W and 12W and
may include the installation of a check valve at each well.
The scope of services presented herein represents Metcalf& Eddy's efforts in supporting
the City for the project.
Scope of Services
1.0 Project Management
1.1 Management
Project Management activities comprise contract administration, coordination of
project staff, monitoring of progress and project costs throughout the project
duration.
1
1.2 Project Meetings
M&E will attend meetings with representatives of the City as part of this project,
as follows:
2.0
a. Two community meetings
b. Project kickoff and predesign meeting
c. One design review meeting each at the 60% and 90% completion levels
d. Pre-bid meeting
e. A preconstruction meeting
f. Two monthly construction progress meetings (not including RPR weekly
meetings)
g. Project closeout
M&E will prepare all presentation material necessary for the community
participation meetings. It is assumed that the City will prepare and distribute the
meeting notices.
Sand Source Study
2.1 Wells 10W and 12W
An investigative study will be performed to identify the source of sand that appears
to be plugging the cartridge filters. A portion of the study will be focused
primarily on Well 12W since this well is a known sand-producer. Findings from
the Sand Source Study will be utilized for developing a plan for sand reduction at
Well 12W. The following services will be provided to conduct a sand-source
study:
Evaluate cartridge filter monitoring instrumentation to ensure that such
equipment is operating properly and not falsely indicating that the cartridge
filters need replacement.
· Collect samples of sand from the cartridge filters for comparison with sand
being produced from the supply wells. Sand production at Well 12W will be
evaluated first since sand production from this well appears to be significant.
· Conduct sand content testing on each of the active supply wells to determine
the extent of sand production from each well (a total of seven wells).
· Perform television surveys (through a subcontractor) of Wells 10W and 12W
under pumping conditions. Well casing will be inspected for holes and the
open hole formation will be observed while pumping the well to help identify
intervals from which sand is being produced.
2
Full time resident observation services would be provided with this sub-task.
It is assumed that the television surveys would take one full day.
Use the results of the television surveys to assist in the evaluation of available
options for reducing sand production at Wells 10W and 12W. Options to
evaluate may include development of the wells and installation of a sand-
separator at each well or at the WTP raw water intake.
2.2 Raw Water Line
If the Sand Source Evaluation does not identify the source of sand as being
wells specific, conduct a television survey (through a subcontractor) of each of
the raw water lines to determine if a breach in the line is resulting in the
introduction of sand into the line. This Task assumes that a total of 6,000
linear feet of raw water line will undergo inspection via television survey and
the lines are 12- to 24-inch.
Full time resident observation services would be provided with this sub-task.
It is assumed that the television surveys would take a maximum of four full
days.
A written Technical Memorandum summarizing the findings of the sand-source
evaluation will be prepared.
3.0
Sand Reduction Plan
A sand reduction plan to reduce the amount of sand reaching the cartridge filters
will consist of the following:
Consider individual well development, installation of sand separators at each
supply well and/or at the WTP raw water intake will be considered for this
portion of the study. If the television survey of the raw water line reveals that
a breach in the raw water line is a source of sand, the Sand Reduction Plan will
include a plan for repairing the raw water line.
Prepare technical specifications to allow the execution of the sand reduction
plan. Technical specifications shall be provided to the City for attachment to
appropriate front-end contract documents.
The technical specifications will be part of the overall project bid package.

4.0
Well Development/Raw Water Line Pigging
4.1 Development of Wells 10W and 12W
Upon completion of the Sand Source Evaluation, it may be determined that
aggressive development of Wells 1 OW and 12W is the most appropriate method of
reducing sand production from these wells. If aggressive development of Wells
10W and 12W is determined to be necessary, this Task will consist of the
following:
· Provide subcontracting services for the performance of aggressive
development of Wells 10W and 12W. The services consist of one
mobilization, pulling pumps from each well, and a maximum of 120 hours of
development time per well (budgeted at $225 per hour).
Provide resident observation services during well development. For budget
purposes it is assumed that resident observation services during well
development will average 4 hours per day and is assumed to require 4 days of
development per well.
4.2 Development of Wells 4W, 5W, 6W and 13W
Wells 4W, 5W, 6W and 13W have been constructed and developed; however, the
wells have been idle since their original construction. The open-hole interval of
well 13W is known to have collapsed during testing, however, the extent of hole-
collapse is unknown. Extensive development may or may not be required at each
of the wells. Sand production during development will be monitored closely to
determine the necessity for further development. The development of Wells 4W,
5W, 6W and 13W will consist of the following:
· Prepare well development plan for submittal to the City and the City-selected
Contractor (a~er bid phase). The plan will include over-pumping the wells at a
rate of 3,000 to 5,000 gallons per minute (gpm).
· Provide resident observation services during well development. Resident
observation services are estimated at 8 hours during the first day of
development at each well and 2 hours per day following the first day of well
development if additional development is deemed necessary. For budget
purposes, an average of 24 hours of development time per well for wells 4W,
5W, and 6W is estimated. Well 13W is estimated to require approximately 60
hours of development time.
If, during development, it is determined that any of the wells are sand
producers, an additional 24 hours per well of development time and/or the
design of sand separators will be considered.

4.3 Raw Water Line Pigging and Disinfection
The water lines for Wells 4W, 5W, and 6W shall be pigged to remove any sand
that may be present in the line. Each of the lines and wells 4W, 5W, 6W, and 13W
shall then be disinfected. The following services will be provided under this task:
Provide subcontracting services for disinfecting Wells 4W, 5W, 6W, and 13W
and their associated raw water lines and pigging of the raw water lines at Wells
4W, 5W, and 6W. Pigging shall be completed prior to disinfecting the lines. It
is assumed that the City will provide sampling and laboratory services for well
disinfection, a total of 6,000 linear feet of raw water line will undergo
inspection via television survey, the City has all pigging stations needed for this
task, and the lines are 12- to 24-inch.
