Reducing the amount of solids and grease |

Grease traps/grease interceptors are typically reservoirs, which
vary in size, built into a discharge piping system a short
distance from the grease producing area. Baffles in the traps
slow the wastewater flow and reduce turbulence allowing the
grease and water to separate. Grease naturally rises to the
surface, and the trap retains the grease while allowing
grease-free wastewater to flow into the sewer system. Grease
must be removed from the trap periodically.

Grease Trap is basically a device that captures grease entering
a system before it reaches the sewer lines. Usually used in
commercial applications such as restaurants or cafeterias.
Grease traps capture the oil and grease from the flow of
wastewater by slowing down the flow of hot greasy water through
the grease trap (actually a tank) and allowing it to cool. As it
cools, the grease and oil separate out of the water and float to
the top of the trap. The cooler water continues to flow down the
drain pipe to the sewer while baffles prevent the accumulated
grease and oil from flowing out of the grease trap. The size of
the grease trap depends largely on how much waste your business
produces and how often you perform trap maintenance.
Grease traps may be located inside or outside of the building.
Traps that are located inside the building tend to be smaller
and require more frequent maintenance. Traps that are located
outside the building tend to be larger and may be less
disruptive to maintain. Outside grease traps will operate
differently in winter versus summer and are more prone to
clogging during cold weather. As a business owner/manager, you
should know where the grease trap, drain lines, and clean-outs
are located at your restaurant.
Proper cleaning and maintenance of the grease trap and drain
line reduces the amount of solids and grease going into the
public sewer system and minimizes the likelihood of back-ups or
blockages. Some sanitation districts and/or municipalities
require grease traps and periodic maintenance and inspections
for specified businesses. This is because untrapped oil and
grease in the wastewater decreases pipe capacity over time and
eventually will cause the pipe to clog. Piping systems without
grease traps need to be cleaned more often and some piping may
have to be replaced sooner than otherwise expected. Excessive
grease sent to the wastewater treatment plant can also overload
their system and cause the facility to exceed its allowable
discharge limits. Running extremely hot water down the drain
only moves the problem down stream, and may only make it worse.
Fixing a sewer line blockage can be expensive, both in terms of
potentially lost customers and repair cost. If the pipe clog is
within your building sewer line, you will be responsible for
fixing the problem and paying all costs. If the clog is in the
public sewer line, but can be traced to your restaurant, you
will be liable for paying all or a portion of the repair costs.
Accumulating the oil and grease close to the source in a
properly maintained grease trap is the most cost-effective way.
