Capabilities
H2OMAP 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 H2OMAP Designer run, the
user is presented with the best identified solution for
the input parameters specified. H2OMAP 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
H2OMAP Water 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 H2OMAP Water
for maximum efficiency and accuracy. Because H2OMAP Water
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 - H2OMAP Water 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).
Users Manual
A very comprehensive users manual and a detailed
step-by-step tutorial guide you through all the powerful
and rich features and capabilities of the H2OMAP Water Designer.
An extremely user friendly and intuitive context sensitive
on-line help facility is also available to you at all
times through a menu selection or by simply pressing the
F1 key.
