CHEN-MOORE PROJECT NO.: 508.001
PROJECT TITLE: Water Treatment Plant Process Efficiency and Control Improvements
This Work Authorization, when executed, shall be incorporated in and shall become an integral
part of the Agreement for Professional Services dated September 10, 2021, between the Village of
Tequesta ("VILLAGE"), Chen -Moore & Associates ("CONSULTANT"), and Wright -Pierce, Inc.
(SUBCONSULTANT) hereafter referred to as the Agreement.

VILLAGE owns and operates Public Water System (PWS) No. 4501438, which provides potable
water to the customers within the VILLAGE's water service area through approximately 5,045
connections. The PWS generally consists of fourteen groundwater wells, a water treatment plant
(WTP) with two separate treatment trains, and over seventy-two miles of water distribution mains
ranging in size from 4-inch to 16-inch in diameter.
The PWS has a Florida Department of Environmental Protection (FDEP) permitted maximum day
operating capacity of 6.33 million gallon per day (MGD). VILLAGE's South Florida Water
Management (SFWMD) Water Use Permit (WUP No. 50-00046-W), which expires on October 31,
2031, allows the VILLAGE to withdraw up to 1,594 million gallons (MG) annually with a maximum
monthly withdraw limit of 230.11 MG.
The WTP generally consists of a 2.7 MGD sand filter treatment process, a 3.6 MGD reverse osmosis
(RO) treatment process, one 0.75 MG water ground storage tank (GST) and one 2.0 MG GST for
finished water storage, and a high -service pump station (HSPS). The HSPS pumps finished water
from the GSTs into the water distribution system. High -Service Pumps 1 through 4 are vertical turbine
pumps located outside, near the 0.75 MG GST, and are each equipped with 40 HP motors. Pump 4
has an adjustable speed drive. Pumps 5 through 7 are horizontal split -case pumps located in a pump
room next to the RO Process area. Pumps 5 and 6 are equipped with 125 HP motors, and Pump 7 is
equipped with a 75 HP motor. Pumps 5 and 7 have adjustable speed drives.
WORK AUTHORIZATION NO. CM UTL21.01 1 of 7
The Sand Filter treatment system was originally installed in 1977 as a GreensandTm filter for iron
removal. In 1982, the filter media was converted to sand/anthracite. In 2000, the VILLAGE
constructed the first phase of the reverse osmosis (RO) treatment train. The treated water from both
treatment trains is combined in a clearwell, prior to being pumped into the GSTs before distribution.
Evaluations of the existing treatment systems, SCADA systems, and distribution systems were
completed by the CONSULTANT and SUBCONSULTANT in 2021 as a separate project. As a part
of the evaluations, opportunities for energy savings and better operational control were identified.
These opportunities were translated into specific proposed improvements to the treatment, SCADA,
and pumping systems.
The VILLAGE has requested the CONSULTANT and SUBCONSULTANT to perform the
professional services required to implement these proposed improvements. SUBCONSULTANT will
provide the below services to assist CONSULTANT with this project.
H. SCOPE OF SERVICES

TASK 2 — Support Services
A. Survey
Through the use of a subconsultant, a Professional Surveyor, registered in the state of Florida,
will perform a boundary and topographic survey of the Project area (as shown in Exhibits A
and B). The survey activities of the selected site will include:
I. A Boundary Survey as defined in Chapter 5J-17, F.A.C. of the overall subject
property (Exhibit B) per the title report or last deed of record, as provided by the
VILLAGE.
a. Any existing access on, across, or over the parcel will also be shown.
2. Review available as -built survey of utilities.
3. Contact Sunshine 811 for the project area.
4. The Surveyor will perform a topographic survey for the project area including:
a. Set horizontal and vertical control (temporary benchmarks) throughout the
project area
b. Conduct 1-foot contour topographic survey based on NAVD 88 Datum and
horizontally to Florida State Plane Coordinates based in NAD83/201 l and
prepare digital terrain model of surface.
c. Locate buildings, structures, building floor elevations, fencing, roadways,
trees (8-inch in diameter or greater), curbs, water surfaces, sidewalks, catch
basins, manholes, fencing, and utility poles for the proposed project.
d. Locate painted surface markings/locates of underground utilities;
e. Locate inlets, storm manholes, culverts, outfalls and control structures;
£ Determine existing elevations of manhole rims, structure invert and pipe
invert elevations on accessible sanitary and storm manholes, inlets, culverts
and lift stations.
g. Property boundaries, easements (if information is readily available).
The V I LLAGE will perform field investigations including ground oenetratine radar (GPR) and
test holes using vacuum extraction to verify the locations and depths of specific utilities.
Subsurface utility information will be used to assist in the_Wout of the new improvements and
pipeline connections. Once the utility has been exposed, depth, diameter and material type will be
obtained and provided to the CONSULTANT and SUBCONSULTANT to verify designation and/or
potential utility conflicts with the proposed design. The SUBCONSULTANT will help direct
VILLAGE staff on areas to perform GPR and specific areas for test holes.
