Design
Capabilities
InfoWater Designer provides very sophisticated
pipe network optimization capabilities for reliable,
cost-effective, and efficient design and rehabilitation
of water distribution piping systems. It treats
the design and rehabilitation conditions as an implicit
nonlinear mathematical optimization problem. All
aspects of the water distribution system can be
considered within the optimization, including pipes,
pumps, and storage tanks. The optimization problem
consists of determining the best
combination of pipe system improvements rehabilitation
(cleaning and lining), replacement, strengthening,
and expansion options as well as the construction
of new pumping and storage facilities
to meet desired hydraulic and water quality
performance criteria at minimal cost.
The user has considerable flexibility in specifying
improvement unit costs (i.e. cost per length, pump
cost, and/or cost per volume of storage) for each
type of candidate improvement (construction of a
new, parallel, or replacement pipe, rehabilitation
of a pipe through cleaning, lining, or other method;
additional storage; and increased pumping capacity)
alternatives. Any number of unit costs may be designated
for the same existing pipe characteristics and/or
new identical pipe sizes so that accurate estimated
costs based on urban versus rural areas, high traffic
versus low traffic areas, and other pipe installation
conditions can be accurately represented. This gives
you complete control over system improvement costs
and streamlines the development of your Capital
Improvement Program. The user can also specify the
portion of the system to be optimized. Any desired
section of the network model can be selected for
optimization including the entire system, any particular
sub-division, pressure zone, or any area selected
through a database query. A database query may be
applicable if the user is evaluating different rehabilitation
options for aged pipelines (typically with low roughness
values).
Pipes, pumps and storage tanks selected for an optimization
run can be lumped into distinct groups
based on the cost and specific characteristics.
Separate facility groups are then identified with
the appropriate cost code and allowable improvement
actions. Finally, target performance constraints
are specified such as minimum allowable junction
node pressures, maximum allowable pipe velocities,
and maximum permissible pipe hydraulic gradients.
Following the completion of an InfoWater
Designer run, the user is presented with the best
identified solution for the input parameters specified.
InfoWater Designer output results include
all recommended additional or increased storage,
additional pumping as well as new, parallel, and
replacement pipes and all recommendations for existing
pipe improvements through cleaning, lining, or other
identified methods for increasing the hydraulic
carrying capacity of existing pipes.

Optimization Methodology
InfoWater Designer provides a fully automated approach
to reliable and efficient pipe network optimization.
It utilizes a highly advanced variation of the Genetic
Algorithm optimization technology closely coupled
with the InfoWater for maximum efficiency and accuracy.
Because InfoWater Designer is able to retain the
reality of existing water distribution systems,
it readily provides you with an effective and practical
tool to optimize design and rehabilitation of these
piping systems and improve their reliability and
integrity at reduced costs.
Genetic Algorithms - InfoWater Designer uses
the latest advances in computational Genetic Algorithms
with superior elitist and global control strategies
to rapidly search in sub-quadratic times for superior
low-cost design/rehabilitation options that meet
all required performance criteria. It is structured
in an object-oriented framework allowing large network
models to be solved in expeditious times. Both English
and Metric units along with the Hazen-Williams,
Darcy-Weisbach (Colebrook-White), or Manning friction
loss equations are fully supported.
Multi-Objective Design - Network models can
be directly optimized considering any modeling condition
time frame (e.g. maximum day), multiple simultaneous
design scenarios (e.g., find the single optimum
solution that provides the standard of service under
peak day for normal operation + average day under
a failure scenario), multiple fire flow scenarios,
and complete EXTENDED PERIOD SIMULATION (dynamic)
designs (e.g. 24-hour operational design).
