Graphical
Model Creation
Based on AutoCAD graphics, H2ONET Analyzer
optimizes on-line data integration and bi-directional
information exchange for complete network model
creation and maintenance, eliminating time-consuming
translations and ensuring data integrity and reliability.
Model Drawing - Network models can be generated
at any scale or to precisely match actual system
layout based on user-definable drawing scales. Pipes
can be of any shape (curvilinear pipes) and their
lengths are automatically computed to the scaled
drawing length. Street and parcel maps of your system
can be displayed as background images to create
a true living network model. Text and specialized
symbols can be added to any map element.

Unidirectional Flow Identification Path -
H2ONET Analyzer’s unique unidirectional
flow identification path module lets you automatically
determine the sequence of water routing from any
node to help you strategically manipulate hydrants
and valves to consistently flush your system with
clean water. This ensures that the water used in
the flush sequences remains clean. Very useful for
planning unidirectional flushing sequences for removing
non-solidified deposits using internal water velocity
in the pipes.
CAD Drawing Conversion - A highly efficient
Polyline conversion module lets you automatically
convert your CAD (e.g. AutoCAD, MicroStation) drawing
with curvilinear line representations to an H2ONET
Analyzer working network map. Graphical "arc"
representations (pipe jumps) are automatically placed
at the locations of pipe crossings for visual interference
detection. The size and orientation of all arcs
can be adjusted by the user.
Inheritance-Tree Type Scenario Manager -
An indispensable master planning tool, H2ONET
Analyzer offers a fully automated and extremely
comprehensive tree-type scenario manager. You can
now maintain a single model of your water system
and quickly construct and evaluate a virtually unlimited
number of network conditions to support your capital
improvement decisions. Change a pipe diameter or
status, pump power, control or schedule, valve setting,
nodal demand, tank level or size, chlorine dosage
and any of these combinations in an easy-to-use
tree-like structure and compare modeling results
instantly. You can even directly extract (cut) one
or more individual pressure (or boundary) zones
from the main simulation model as well as merge
(paste) together any number of models for detailed
analyses. You also have the ability to automatically
generate specialized skeletal models (automated
skeletonization) of your water system based on any
specified set of parameters (e.g., all pipes with
diameter greater than 12 inches). Our revolutionary
scenario management incorporates visual facility
sets to let you see how your system will react to
different conditions and planning horizons.

Cost Analysis - H2ONET Analyzer’s
facility costing module lets you fully utilize ENR
Construction Cost Index (CCI) to automatically calculate
the costs of recommended physical improvements to
your water system.
SCADA Interface - H2ONET Analyzer
provides the capability to extract real-time modeling
data directly from your SCADA system in ASCII format.
The data consist of tank water levels, pipe status,
pump status and settings, valve status and settings,
and various demand scaling options. Recorded pressure
and flow readings can also be imported for model
calibration/verification purpose. Alarm settings
for tank level, junction pressure, and pipe/pump/valve
velocity are fully supported. Such on-line modeling
and monitoring capability is essential for operator
training (emergency response), confirmation of normal
system performance, projection of operating scenarios,
system trouble-shooting, and improvement of overall
operations.

Network
Analysis
H2ONET Analyzer provides unsurpassed
network analysis and simulation capabilities. With
H2ONET Analyzer, your entire water distribution
system or any selected portions can be analyzed
under steady-state and extended period simulations.
The program tracks the flow and velocity of water
in each pipe, the pressure and grade and each node,
the height of water in each tank, the discharge
flow and pressure for each pump, and the movement
and fate (growth or decay) of water quality constituents
as they travel through the distribution system during
a dynamic simulation period. Water age and source
tracing can also be effectively simulated.
Analysis Engines - H2ONET
Analyzer is based on the rigorous Modified Hybrid
Method (MHB), which is the most powerful and computationally
efficient method of network analysis. Both English
and Metric units are fully supported. Pipe friction
loss computations can be carried out using the Hazen-Williams,
Darcy-Weisbach (Colebrook-White), or Manning equations.
The dynamic water quality model accurately simulates
both conservative (e.g., fluoride) and reactive
(e.g., chlorine, THM) species and is equipped to
model such phenomena as reactions within the bulk
flow, reactions at the pipe wall, and mass transport
between the bulk flow and pipe wall. The pipe wall
reaction rate constant can be expressed as a function
of pipe roughness for improved calibration. H2ONET
also allows for time-varying concentration of mass
inputs at any location in the distribution system,
and models storage tanks as being either complete
mix, plug-flow, or two-compartment reactors.
Node Demands - System demands can be allocated
to junction nodes in terms of their constituent
components (e.g., residential, industrial, commercial,
recreational, unaccounted for water, etc.) or directly
from billing records (customer meters). Separate
base demands as well as multiple diurnal curves
(demand patterns) can be assigned to any node. Demand
curves can be described in a stepwise or continuous
(linear) fashion over the simulation period. Pressure-dependent
demands can also be effectively simulated.
Dynamic Fire Flow Modeling - Using an exact
analytical solution of the basic pressure-flow equilibrium
relationships, H2ONET Analyzer provides
highly efficient and accurate calculations of fire
flows (residual pressures, available flows, design
flows) based on various types of structure (e.g.,
single family, multifamily, commercial, etc.) and
other fire characteristics. Single or multiple simultaneous
fire flows along with their expected duration are
fully supported in a dynamic environment to more
effectively model real world conditions. You can
now rapidly assess the adequacy of your water system
to meet target fire flow requirements and plan for
necessary system strengthening and improvements.
Fire Hydrant Analysis - Fire hydrant rating
curves can be automatically generated by the program
for any user-selected time period and for any or
all hydrant locations. Complete residual pressure
vs. available flow calculations are directly performed
ranging from the imposed static demand to the maximum
available flow at atmospheric pressure, at any user-specified
flow increments.
Energy Management - H2ONET Analyzer
offers comprehensive energy management capabilities
to assist you in identifying the most energy-efficient
and cost-effective pump scheduling and operational
policies. You can also evaluate storage/pumping
trade-offs and rate schedules, and consistently
monitor cost of operations. This module handles
time-varying energy rates and demand charges, as
well as constant efficiency and variable pump efficiency
(efficiency vs. flow data) curves for any pump in
the system. It calculates all essential costs for
pumping stations. You are now able to accurately
assess the operational efficiency of your water
distribution system and provide for maximum energy
efficiency and energy cost savings. This simulation
capability is especially useful for systems where
energy related charges are significant.

Logical Rule-Based Controls - H2ONET
Analyzer uses a highly sophisticated rule-based
logical control language (If, Elseif, Else, And,
Or, Not) for defining decision rules (PLC emulation)
to precisely simulate the hydraulic behavior of
your water system. You can automatically control
the status of your pipes, pumps, and valves based
on time (time switch), tank water levels (grade
switch), node pressures (pressure switch), pipe
flow rates (flow switch), and any of their combinations.
System Head Curves - System head curves for
pumps can be automatically generated by the program
for any flow condition specified (e.g. low head,
design head, and high head) for use in the effective
design of pumping stations.
Reservoir Characteristics - H2ONET
Analyzer provides you with considerable flexibility
in modeling distribution storage facilities. The
program accommodates all types of storage node characteristics
including common and multiple inlet/outlet tanks,
cylindrical and variable-area tanks (e.g., ellipsoidal
tanks), hydropneumatic tanks, and constant and variable
head reservoirs. The latter is extremely useful
in modeling system partitioning of multiple pressure
zones.
Valve/Meter Types - H2ONET Analyzer
accommodates the complete library of hydraulic network
components including check valves, pressure regulating
valves, pressure sustaining valves, pressure relief
valves, pressure breaker valves, vacuum breaker
valves, throttle control valves, motorized throttled
valves, flow control valves, bi-directional flow
totalizers (flow meters), float valves, and user
defined (customizable) valves. The latter can be
effectively used to model any type of valves based
on user-specified pairs of head loss-flow data points.
Minor (local) losses are calculated from input loss
coefficients.
Pump Types - Pumps can be included in any
line of the pipe system. The characteristics of
pumps can be described in two ways: the useful power
the pump puts into the system can be specified or
by points of operating data. You can enter an unlimited
number of data points to approximate your pump curves.
Net Positive Suction Head requirements (available
NPSH, required NPSH, and cavitation index) are calculated
to ensure cavitation free operation. Turbines can
also be effectively simulated.

Color Mapping - The entire network, or user-specified
portions of the network, can be color-coded according
to any network variable: pipe size, flow rate, velocity,
head loss, hydraulic slope, node pressure, grade,
demand, elevation, water age, percent source contribution,
water quality concentration, and any other database
attribute. Use this feature to visually differentiate
among pipes of different material, diameter, and
date of installation, and among numerous pressure
zones by specifying a different color for all pipes
in each of the separate zones.
Map Labeling/Annotation - H2ONET
Analyzer provides "what you see is what you
get" annotation. You can annotate and view
simultaneously modeling data and results for network
attributes and for any hydraulic conditions directly
on the network map (AutoCAD drawing). These dynamic
labels automatically update as you switch between
hydraulic time steps and scenarios. Annotation of
the various element attributes can be directly customized
with user-defined symbology, color, size, and style.
Flow directional arrows are automatically calculated
and can be displayed along with text information.
Dynamic Browser - The H2ONET Analyzer
browser windows allows you to instantly locate network
elements and view modeling results in a "point
and click" mode for any time period of a dynamic
simulation.
Contour Maps - For any given simulation run,
H2ONET Analyzer allows you to efficiently
generate accurate smooth contours for any numerical
database attributes including elevation, pressure,
hydraulic grade line, demand, chemical concentration,
water age, percent source contribution, fire flow,
customer complaint, and other pertinent modeling
parameters. Beautiful T.I.N. based contours can
be generated directly on the AutoCAD map for the
entire network or for any user-selected portions
of the network. Each contour map can be assigned
to any specific AutoCAD layer thereby allowing multiple
parameter contours to be overlaid and displayed
on a single drawing. Color grading and coding and
numerical interval ranges as well as various useful
graphical presentation options are user-specified.
Time-Series Graphs - Multiple time-series
graphs can be generated for a wide variety of variables
such as pipe flow rate, velocity, head loss, nodal
demand, pressure, grade, water quality, pump operating
curves, efficiency, useful and required power, energy
cost, tank water level, total and net system demand,
and others. You can customize your graphs in various
fashions (2D/3D bar, 2D/3D line, 3D strip, area)
and overlay several graphs on a single display.
Observed field data can also be directly linked
to any graph. This feature is especially useful
for model calibration. You can even compare results
from several scenarios on the same graph.
HGL Profile - H2ONET Analyzer
calculates residual heads and allows you to display
the ground elevation and hydraulic grade line profile
for any connected series of routes and for any time
period to better optimize your designs. You can
completely customize the format and layout of the
profile plots for professional presentation.
Visual Animation - H2ONET Analyzer
offers a very useful VCR-style animation feature
that helps you step through an EPS and instantly
visualize and comprehend the dynamic performance
of your system such as temporal variations in HGL
profile, pump operation, and water quality propagation
for the length of the simulation period.
Database Queries - Sophisticated query tools
let you build complex intelligent queries on any
database and modeling attribute (both input and
output data) to meet a single criterion or multiple
criteria simultaneously. Such capabilities can greatly
assist you in the decision making process for network
asset inventory, rehabilitation requirements, and
financial planning. Query results can be displayed
graphically, in tabular format, printed, or exported
to a standard spreadsheet or word processor.
Customizable Reports - Comprehensive report
generation tools are provided for simultaneous display
of input and output variables. Report tables can
be completely customized by selecting the variables
to display, the order in which they appear along
with the desired units, display precision, column
width, and format, and the corresponding hydraulic
time period. You can include the entire network,
any portions or selected elements. Each table can
be sorted according to any variable and filtered
based on any search criteria. Maximum, minimum and
average values for all variables are automatically
calculated and reported for EPS runs.
