MANAGEMENT AND PLANNING SERVICES, INC. ("PUMPS, INC.") BASED ON
A NEWLY ESTABLISHED CCNA CONTRACT PURSUANT TO RFQ NO. 2024-005,
FOR HYDRAULIC MODELING OF THE CITY'S WATER DISTRIBUTION
SYSTEM IN THE AMOUNT OF SEVENTY THOUSAND DOLLARS ($70,000.00);
PROVIDING FOR CONFLICTS; FURTHER, PROVIDING FOR AN EFFECTIVE
DATE.
WHEREAS, the City of Dania Beach's hydraulic model for its water system has not
been updated in approximately fifteen (15) years, rendering it ineffective to address the City's
new and emerging demands for service; and
WHEREAS, the increase in demand from new and larger developments across the City,
in addition to its aging infrastructure, has further increased the need for an updated model of the
system; and
WHEREAS, the updated hydraulic model will define the City's water and pressure
sewer systems, quantify capacity, and provide other key information and data on the system; and
WHEREAS, the updated model, which will also include global information system
("GIS") mapping, will guide infrastructure improvements which will in turn facilitate new
developments to connect to the system without impacting existing customers;
NOW, THEREFORE, BE IT RESOLVED BY THE CITY COMMISSION OF THE
CITY OF DANIA BEACH, FLORIDA, AS FOLLOWS:
Section 1. That the above "Whereas" clauses are ratified and confirmed as being true
and correct, and they are made a part of and incorporated into this Resolution by this reference.
Section 2. That the proper City officials are authorized execute an agreement to
accept the proposal from PUMPS Inc. to complete the hydraulic model, attached as Exhibit "A"
and incorporated into this Resolution by this reference.
Section 3. That funding for this project is available and appropriated in the Water
Utility Distribution/Professional Engineering Account No. 401-33-02-533-31-30 in the amount
of Thirty Five Thousand Dollars ($35,000.00) and the Sewer Utility Collection/ Contractual
Services Account No. 402-35-02-535-34-10 in the amount of Thirty Five Thousand Dollars
($35,000.00).
Section 4. That all resolutions or parts of resolutions in conflict with this Resolution

HYDRAULIC MODELS
The City of Dania Beach desires to update the current water and wastewater hydraulic
models for the Utility Service Area. This work order is made in response to a request by
the City of Dania Beach {"City"} for services for developing hydraulic model of the water
and wastewater system for the City which includes.
* GIS based
a Use existing data and modeling information to the extent possible
• Utilize asset information previously gathered to the extent possible
• Update the water and pressure sewer atlas to current
+ Create a basic hydraulic model of both systems for use by the City to measure
impacts to the piping system from new development.
Note the City will expect that developers will use the model result to verify service
availability and for updating for future users.
Task 1— GIS Database S10,000.00
Public Utility Management and Planning Services, Inc. and its subconsultant will update
the GIS database for water and sewer piping systems throughout the City. The focus will
be on larger diameter lines for modeling purposes. Background data will be collected for
land use, road and parcels. Billing information will be geocoded and mapped to provide
locations of meters.
Task 2 — Steady State Hydraulic Models for Water and Force Maims-S50,000.00
Public Utility Management and Planning Services, Inc. will utilize the a subconsultant for
portions of this task. Innovyze Cris a GIS based model for hydraulic systems. The
consultant team will acquire rights to use the model for development. This City will need
to decide where the ultimate model will reside. The model will include all pipes 12 inches
and large and may include 4-8 inch pipes as necessary to calibrate the model successfully.
PUMPS and its subconsultants will perform the following tasks:
Z4 Water Model Development
Pumps will collect Water GIS Data
• Water Geodatabase
• Background Data (Land Use, Future Land Use, Roads, Parcels, etc)
• List of specific operational data
Pumps will Build Water Model
• Import data into model
• Import average billing demands
o Average week
o Max week
• Import Operational Data
o See List
Pumps will Verify Water Model
• EPS (Extended Period Simulation) 24 hour simulation
o Review Scada
o Establish Diurnal Curve
o Review Average Day
o Maximum Day Factor
• Verify model
• Make adjustments where necessary to depict actual system
Pumps will Calibrate the Water Model (Limited Calibration)
• Fine Tune Verification
o Adjust C-Factors
o Address Diurnal
• If Necessary, Limited Field Calibration
o Develop Calibration Plan
o Install Pressure gauges (4 gauges reading for 1 week)
o City must install pressure gauges
o City must provide Scada for testing period
Pumps will Run Water Model Scenarios
• Existing Conditions
Approved Developments
o Ave Day Diurnal
o Max Day Diurnal with Fire Flow
2B Pressure Sanitary Model Development
Pumps will Collect Sanitary GIS Data

• List of specific operational data
o Pump curves
o Private Lift Stations
o Wet well depth and float elevations
o Flow 1 Pressure data. from Hollywood Connection
Pumps will Build Sanitary Model
• Import data into model
• Import Operational Data
o Pump curves
o Wet Well

• Steady State
o Maximum Head Scenario (all pumps on)
o Minimum Head Scenario (master pump stations on)
o Verify model with scads
a Verify model against Hollywood Connection
• Make adjustments where necessary to depict actual system
o Analysis of run times
