Welcome to the Design
Software page of Water Management
This page is dedicated to the Water Management Specialists
Irrigation Design Software which we commonly refer to as "IDA" or
Assistant. This design software was
developed by an irrigation designer for other irrigation designers.
As the name implies, it is an "assistant to the designer. The software
will follow the convention of the of the design process from the beginning to
The software can be customized for a specific state.
The state of Texas has the most aggressive laws in the nation. The
software program complies with all of the TCEQ (The state of Texas governing
body for irrigation).
Design Assistant software will ....
Reduce your design time by up 60% regardless if
you are using a CAD type of software or using a drafting table. The
IDA (Irrigation Design Assistant) walks you through the entire irrigation design
process from establishment of the flow capacity of your water source to the
irrigation schedule and hydraulic statement. If you are in the State of
Texas, you are regulated by the state agency called the Texas Commission on
Environmental Quality. This agency, via the State of Texas, has a complete list
of mandatory design requirements. This irrigation design software will
comply with all phases of the TCEQ requirements. If you are doing
irrigation design work outside of the State of Texas then this software will
assist you in designing one of the most water and cost efficient irrigation
The IDA software will utilize several key items
that the user will select via "Pull Down Menus" in the design process.
As each additional piece of data is selected by the user, the software provides
more and more answers and guidance in the design process. Listed below are some
of the key items the user will select or input, and the software will then use
this information to calculate values used in the design process automatically.
The IDA will determine the most optimum GPM flow rates
utilizing water meters based on AWWA flow values for High or Low water
pressures. (Commonly called the 75% rule or 10% rule). In addition
the software will offers the user the options of pump flows GPM, water wells,
or the average velocity rule through designated pipe.
The flow rates are calculated based on multiple factors
including static water pressure, elevation, meter size, city main size, HP of
pump, holding capacity of storage tanks, usage of "Cycle-Stop Valves"(tm)
The static pressure value will determine the optimum
method to utilize in determining the available GPM of the water meter.
In addition, the user will input known elevations on the project and the
software will automatically determine the impact on the design process, the
hydraulics, and the water meter capacity. This information will also
assist the user in pre-calculating the potential "ADJUSTED DYNAMIC
PRESSURE" so that a product can be selected from the manufactures catalogs
The IDA offers seven (7) pre-determined
micro-climates and seven (7) fully customizable user defined micro-climates
The IDA has fully modifiable "Watering
Window" function which will allow the user to establish a complete schedule
Purveyor allowed Days, Hours, or Gallons
Client allowed Days, Hours, or Gallons
Exemptions such as "Drip", Non-Potable, or second source
The IDA offers two options for determining
ET or Evapo-Transpiration. There is a Texas published historical data
base that provides 55 cities with a "30" year historical
data base or there is a user defined data base.
The end user will select their preferred
product from "pull down menus" . This information will allow the
software to match application with micro-climates, code requirements, ET Rates
to Precip Rates, or any other user or client required input
Once this and much more
information is selected or determined, the software can then begin to perform
The software will follow a convention of
steps that all irrigators will follow in the design process. These steps
also use a building block format, in that the information obtained or
calculated in one step is then used in solving or addressing the next step in
the irrigation design process.
This section will allow the irrigation
designer to break the project into different logical areas. The user
will then input the length and width of the area they are attempting to
irrigate and then select the Micro-Climate they are designing to. The
software will then determine the most efficient actual head placement for the
Head and Row spacing down to the nearest 10th of an inch. It will
provide the user with multiple options of product at their disposal that will
fit in the areas and micro-climates that were previously selected. If an
application will not work, it will be reflected as N/A for that application.
The end user can either use the manual mode or allow the software to make the
decision of the head selection automatically. This process is utilized
for spray, rotor, rotator, and drip applications.
The software will automatically
determine the total number of zones required, how many and which micro
climates are needed, as well as the optimum GPM for each zone.
(The user has the option to do a "What - If" function to look at the
forecasted results of utilizing a second meter or alternative water source.)
The user will then build each specific zone with the software providing
guidance with information such as maximum GPM per zone, GPM of heads available
for each specific micro-climates, actual head spacing for each product in the
micro-climate (Calculated from the HEAD SPACING function). The valve
sizing for the zone will be determined here, again it will be either an
automatic or user selected function.
The software has two options here as
well. One is automatic and the other is a user input. In the
automatic mode the software will select the largest zone in GPM flow and will
assist in the majority of all the hydraulic calculations. It will assist
the user in the progressive pipe sizing for the worst case scenario. The
user will simply select the type of pipe from a "pull down" menu and then
input the actual GPM and length of each section of pipe and the software will
automatically size the pipe based on 5LFS and will determine the actual
friction loss utilizing the "Williams-Hazen" formula for friction loss.
The software will automatically size the main line and calculate the friction
loss for this. The user can select to use a "Looped Main", and the
software will size and perform all the hydraulic calculations on this as well.
The backflow device will be automatically selected. The software will
automatically calculate the friction loss for the water meter, elevations
(Gained or Lost) valves, and any other miscellaneous items the user has.
The software will calculate the DESIGN pressure, ACTUAL HEAD pressure, and
automatically generate a "HYDRAULIC STATEMENT" that will comply with any local
or state regulatory agency. If the hydraulic calculation determines the
system has failed, it will indicate by how much. It also has automated
information data sets the user can select to address excessive pressures that
may put the system out of compliance to some state codes, such as TCEQ in
ET BASED IRRIGATION SCHEDULE
The software will automatically generate
an Annual ET-Based Irrigation Schedule for all the zones. The software
automatically calculated the actual Precipitation Rate in the Zoning section
and applied the Watering Window data, ET Data, and Micro-climate data.
In the event the schedule violates the defined Watering Window, the software
will adjust the schedule to accommodate the Watering Window. In the
event this is done, the software will define which areas where adjusted, and
by how much. This allows the user to approve or modify the changes.
The software provides the schedule in minutes per day, frequency, and per
cycle as well as providing a percentage of monthly adjustment.
The software provides the user with four
different methods of determining the actual water cost per gallon from their
purveyor. These processes include water, water and sewer, and irrigation
water. In addition it will provide for per gallon, per cubic foot,
average monthly, flow combined water and sewage tier rates, water tier rates,
or user define values.
The software will automatically
calculate the Daily and Monthly water cost and GPM flow rates for each zone
based on the Highest ET rate for the year and the water cost determined in the
previous sections. This gives the user and the end client a working
knowledge of the worst case operational cost of the system both in dollars and
BIDDING AND ESTIMATING
The bidding and estimating section is
comprised of two sections. The first section the user will input up to
five (5) vendors of parts. There is a complete section with "Pull Down
Menus" for product selection, as well as user defined sections. The end
user will input their specific costs for each of these items. In
addition, they have the option of inputting "time and motion" rates into the
software as well as other key costs. The software will then do a
material take-off all the key components except for pipe and wire. The
software will prompt the user in key areas for specific data input and will
then provide a complete material take off and costing for the system.
The user can select pricing from a single vendor or for the best price from
all the vendors. This is a very robust section that will provide the
user with a very powerful financial bidding package. (This section will
be interactive with Auto-Cad(tm) in the 2012 update
version. This update version will also allow all of the data from this
software package to be imported into Microsoft Access(tm)
for relational analysis.)
The software has multiple other
functions that are independent of the automatic process listed above. These
A complete digital Velocity chart which
will calculate velocity in any type of pipe at any pipe flow
A complete digital Friction Loss chart
which will calculate friction loss of any type of pipe at any GPM flow
A complete "Reference Formula" page that
has 18 different calculators that range from SLOPE calculations to ACRE FOOT
Calculations. In addition, it has a automatic Head Placement calculator
A "Stand-Alone" drip calculator that
will determine optimum spacing for in line tubing and single source emitters.
This will also determine actual linear foot of drip tubing needed, including
the number of rows needed
A LQDU (Lower Quarter Distribution
Uniformity) calculator that will calculate the DU of an area based on catch
The software is truly a Irrigation Design
Assistant that will assist all irrigators from the "Rookie" irrigator to
the most seasoned designer. It is built around 2010 Microsoft Excel(tm)
platform so there is not a compatibility problem. This allows
you to create client files and store them as well as merge data into other
Microsoft applications. You will need to have a current licensed version
of 2010 Microsoft Excel(tm) or later. If you have an
older version, let us know and we can provide software for earlier versions of
Excel. Please note that if you are using 2003, there will be some
functions that will not work.
