2. Highland Tank AFamily Business
Since 1946, Highland Tank has been on the leading
edge of tank technology. Initially, Highland primarily
fabricated fuel storage tanks. In 1986, we entered a
new era of fabrication with the development of the
Highland Tank Oil/Water Separator to meet more
stringent environmental regulations to prevent oil
spills and water pollution. As our core business of
oil/water separator fabrication grew, we expanded
our wastewater treatment systems product line to in-
clude Oil/Sand Interceptors, Advanced Filtration Sys-
tems, and Collection Catch Basins.
We put over 20 years of experience into every High-
land Oil/Water Separator we build. Our separators are
unparalleled in performance, ease of maintenance,
structural strength, product compatibility, and corro-
sion resistance. With over 12,000 units in commercial
operation worldwide, our patented oil/water separa-
tors have a proven record of reliability.
Highland engineers have designed a functional means
of primary separation that meets and surpasses fed-
eral, state, and local oil and grease discharge limita-
tion requirements. Our separators handle a wide
range of oily discharges from oil storage and vehicle
maintenance, fueling, and washing areas at petro-
leum, transportation, industrial, military, commercial,
and municipal facilities.
Specifically, our high performance HTC UL-SU2215 ap-
proved separators greatly reduce the level of free oil,
grease, and oily coated solids down to 10 ppm and re-
move free oil droplets down to 20 microns. Highland’s
cylindrical or rectangular separators are available in sin-
gle and double-walled construction for aboveground,
underground, or belowground vaulted installation.

6. Saving Our
Environment
for Future
Generations
The public's increasing interest in the conservation
of the nation's water resources has directly
affected industries worldwide. Pressure to control
harmful oil spills and discharges from industrial
facilities has resulted in increasingly more stringent
regulations. Industries are now facing costly
penalties for noncompliance.
Industrial facilities with oil storage and handling
activities commonly produce wastewater containing
oil, grease, floating debris, and settleable solids.
Highland’s extensive line of wastewater treatment
systems helps these facilities comply with the EPA’s
NPDES regulations for the proper treatment and
discharge of contaminated storm water runoff,
and satisfy SPCC requirements for spill control
and secondary containment.
The method of treatment depends on the concen-
tration, the type of contaminants in question,
and the location of the discharge. The key to
success for collecting, separating, and treating oily
wastewater on-site is properly configuring the best
available technologies to optimize performance
and limit operational costs of the system.
A well designed drainage system equipped with
a Highland Corella® Oil/Water Separator or Oil/Sand
Interceptor as the primary step, frequently com-
bined with an Advanced Filtration Systems (AFS)
as a secondary step, can economically treat most
wastewater flows to achieve nearly all discharge
limitations and water quality standards for
petroleum compounds.

municipal storm or sanitary sewer systems.
Our rectangular separators can serve as
a stand-alone oil/water separator or can

38. Collection Catch Basins
Collection Catch Basins (CB) are designed
to capture sand, grit, debris, and asso-
ciated pollutants discharged from vehicle
maintenance and fueling facilities and
to prevent their entry into the drainage
system. When installed in conjunction
with an oil/water separator, the catch
basin acts as a simple pretreatment device,
to collect this trash and help prevent it
from clogging the drain lines. The result
is also less waste material entering
into the separator!
Catch basins are easy to install, operate,
and maintain. The catch basin’s remov-
able drop-in wastebasket collects trash,
which may be deposited at the service
bay drains or fuel islands. A second
screen welded inside the catch basin,
adds further protection against waste
entering the separator.
Unlike older style concrete units,
our catch basins are constructed
of heavy duty steel that won't crack
or leak.
They’re also available in double-
walled construction to meet
strict environmental regulations
Features:
• Coated mild carbon or stainless
steel construction
• Pre-formed attached grating frame
with heavy duty grate
• Easy access removable basket for trash
collection and removal
• Screened discharge pipe
• Large sediment retention
