H2OMAP SWMM Designer makes
it possible to automatically, reliably and expeditiously
analyze very large and complex urban drainage
systems and determine the optimal solution to
eliminate sewer overflows. It uses the latest
advances in Genetic Algorithms optimization technology
for superior, cost-effective designs. The optimal
solution considers the best combination of sewer
size and slope, pump capacity, and storage volume
that produce the minimum cost while satisfying
user-specified system design/hydraulic performance
criteria such as depth to diameter ratio, maximum
velocity, minimum velocity, and maximum head loss.
Improvement unit costs (i.e. cost per length,
pump cost, and/or cost per volume of storage)
can be specified for each type of candidate improvement
(construction of a new sewer, additional storage,
and increased pumping capacity) alternatives.
Any number of unit costs may be designated for
each sewer size so that estimated costs based
on urban versus rural areas, high traffic versus
low traffic areas, and other pipe installation
conditions can be accurately represented. The
portion of the system to be optimized may also
be specified. Any desired section of the collection
system model can be selected for optimization
including the entire system, any particular sub-division,
a geographical area, or any area selected through
a database query. A database query may be applicable
when evaluating different improvement options
for sanitary sewer verses storm sewer in a combined
system.
Following the completion of a Designer run, the
best identified solution for the input parameters
specified is presented. Designer output results
include all recommended replacement sewers, additional
or increased storage, and modified pumping capacity
for increasing the hydraulic capacity of existing
system. Designer allows for the automatic update
of the H2OMAP SWMM database tables with the recommended
conduit diameters and new roughness values, the
alternative storage volume, and modified pumping
capacity that reflect the computed improvement
solutions. In addition, all recommendations can
be automatically entered into a new user-defined
database field in the existing pipe information
table.
Both Kinematic Wave and Dynamic Wave flow routing
schemes are fully supported.
In summary, H2OMAP SWMM Designer allows wastewater
engineers to generate credible and reliable sewer
systems to reliably convey sewer flows without
surcharging, overflows, flooding, and backups,
while saving a tremendous amount of time and money,
and without sacrificing accuracy or ease of use.
