TASK SCHEDULE
General Description
WATER SYSTEM HYDRAULIC MODEL
Investigative Phase
Review present and future service areas and local
service zones based upon existing system mapping
information and planning data provided by the City.
Review customer water billing reports to determine water
demands based upon established service areas and
local service zone for system modeling purposes.
Prepare a technical memorandum describing the results
of the investigation.
Field Phase
Review existing City operating records to determine the
current performance of distribution system elements
(high service pumps, trunk main flows, storage tank
levels, etc.) to assist in the determination of overall
system performance and the identification of key areas
for specific field tests.
Hazen and Sawyer shall coordinate field study by City
staff of the distribution system to determine performance
of the existing system and to provide base data for
distribution system modeling to supplement existing
operating data, as appropriate.
The City will provide information on pipe material and
approximate age which will be used determine initial
Hazen -Williams "C" values.
Hazen -Williams "C" value flow tests and hydrant flow
tests will be conducted by City staff on key mains and on
a representative number of small mains. In addition to
providing information for the computer model, the tests
will help determine the presence of closed or throttled
valves on the larger mains and missing sections in
smaller mains. Up to six tests would be conducted by
City staff on mains 12 inches and larger, and ten tests
on mains 10 inches and smaller.
City will provide and install a field gauging connections
(typically on fire hydrants or hose bibbs), flowmeters,
pressure recorders and labor as required.

1.3 Analysis Phase
s
Develop mathematical model of the water distribution
system water main skeleton network based upon the
City's existing water distribution CADD base map, taking
into account the results of tasks for model calibration
and verification. A separate model will be developed for
Tamarac Utilities East (TUE). Models shall be based
upon the Cybernet software package. Utilize the model
to identify required facilities to maintain adequate water
supply and pressure for consumption and fire flow
demands based upon planned and projected growth. No
pipelines less than 8-inches in diameter shall be
considered in the skeleton system, except in TUE.
City will provide minimum pressure to be supplied by the
City of Fort Lauderdale, the source of the water for the
system.
After review of the modeling results, Hazen and Sawyer
shall recommend areas for the City to field verify results
and/or add to the skeleton model in the future.
Evaluate model results. Prepare a technical
memorandum identifying problem area and listing
feasible options for rehabilitations, improvements and
expansion of the existing distribution system. The
purpose of the technical memorandum shall not be
construed as to being a "Master Plan".
Completed model of the skeleton system shall be
furnished to the City for future analyses. Training of City
personnel in the use of Cybernet is not included in this
project.

2.2 Field Phase
Review pump station report information to determine the
current performance of transmission system elements to
assist in the determination of overall system performance
and the identification of key areas for specific field tests.
Hazen and Sawyer shall coordinate a field study by City
staff of the system to determine the routing of current
flows and performance of the existing wastewater
transmission and pump station system.
The City will provide information on pipe material and
approximate age which will be used by Hazen and
Sawyer to determine initial Hazen -Williams "C values.
City staff will provide and install all field gauging taps,
flowmeters, pressure recorders and labor as required to
gather the necessary data.
2.3 Analysis Phase
Develop mathematical model of the pump station and
. force main system taking into account current and
projected wastewater flows within individual collection
zones. A separate model will be developed for TUE.
Analysis does not include the gravity system and
lift/repump stations upstream of gravity sewers.
Determine the adequacy of pumping stations connected
to the force main system to meet future pressure flow
conditions under various operational scenarios. Hazen
and Sawyer shall review current flow routing schemes
and recommend modifications to minimize repumping
where feasible. The City shall furnish basic pump
station data from maintenance/inventory records
compiled for each station. Data shall include pump
performance curves, station configurations (two pumps,
three pumps variable speed, etc.) and related data for
implementation. The study area includes up to 50 lift
stations.
After review of the modeling results, Hazen and Sawyer
will recommend areas for the City to field verify results.
