In its simplest form, the concept of
stormwater management is to provide a
means of flow reduction and treatment
prior to discharge from a developed
site. Retention of peak flows under
extreme rainfall conditions is imperative
in maintaining and/or improving our
surface water quality. Highland Tank
Stormwater Detention Tanks (SDT)
play a critical role in many stormwater
management plans.
In some instances, stormwater requires
vigorous onsite storage to avoid hydraulic
overload of the sewer infrastructure.
The intent is to reduce flooding and/or
the potential for overflow at the
wastewater treatment plant.
Protected steel tanks provide the
proper stormwater storage to meet the
treatment volume objective as well as
providing additional capacity for channel
and/or flood protection requirements.
Once the treatment objective is met the
water can be control pumped to the
treatment plant under normal operating
conditions.
Highland Tank SDT are constructed
of carbon steel with choices of tough
high-solids epoxies, polyurethane
and other linings or external coatings.
These “tight
tanks are available for
aboveground and underground
installation based on your needs.
Contact your local Highland Tank
representative to discuss which
coatings best suit your project.
Custom sizes and options are available
including stainless steel fabrication.
Highland Tank will design and
manufacture SDT to relevant AWWA,
NFPA, UL or API Standards. A variety
of manways and nozzle connections
are available including flanged, threaded
and Victaulic
®
. Our team of professionals
will work closely with you to build a
SDT to meet your specific needs.
