8. Technical Presentation Qualification Test
Very tricky arithmetic! Note: This must be done in your head
only.
Do NOT use paper and pencil or a calculator. Try it.
Take 1000 and add 40 to it. Now add another 1000 . Now add
30.
Add another 1000. Now add 20. Now add another 1000
Now add 10 What is the total?
Did you get 5000?
9. Building a “Green” World
Takes Everyone Working as a Team
…and seems to be the focus of every city
11. But,
Commercial
Buildings
Must collect and treat
fats, oils, grease (FOG)
solids and chemicals
before they leave the
owner’s property.
Why do all major cities have a “FOG” program?
22. It’s really hard to keep up!
Green Building Code, EPA, TCEQ
Flood Water Control? Storm Water Quality?
Illicit Wash Down? Grease? Sand/Grit? Oil/Water? Solids? Lint?…
What should drain to Sanitary?
What should drain to Storm?
Who Designs Which BMP?
Let’s Test the group…
25. Grit/Oil Interceptors now required at Parking Garages
for power washing operations
If no Grit/Oil Interceptor is Grit/Oil
installed, Power Washers Interceptor
must vacuum up & transport
all water dispensed.
26.
27. OKC SWQ issues a permit and registration certificate after the applicant
pays all applicable fees. Good for 1 year
35. Park Interceptors are found in Elevator Shafts (unless in Houston)
Each Hydraulic Elevator
Shaft must have an
automatic sump pump rated
for 50 gpm that discharges
into an approved oil/water
separator.
39. New Subject!
Planning for Decontamination Wastewater
From Homeland Security – Post 9/11
Plan to Design for:
•Chemical Warfare Agents
•Biological Disease
•Radioactive Materials
•Compounds used in the
decontaminations process
40. OSHA Regulations
Decontamination shall be performed in
geographical areas that will minimize
the exposure of uncontaminated
employees or equipment to
contaminated employees or equipment.
Includes all operations involving
hazardous waste that are conducted at
treatment, storage, disposal (TSD)
facilities

Sewer Interceptor Design
We know for commercial design:
It shall be UNLAWFUL for any industrial user to discharge into the
public sewer:
Two Most Important!
1. Free or emulsified oil & grease over an average of 100-400 (mg/l)
2. Acids or Alkalis which attack or corrode sewers or sewage disposal
structures or have a pH value lower than 5.0 or higher than 11.0

Grease Interceptors Names IPC & UPC since 2000
Grease Trap
Mechanical Trap
Grease Interceptors
Automatic Grease Removal Device (GRDs)
Gravity Grease Interceptors
Hydromechanical Grease Interceptors
New! FOG Interceptors
A Confusing Mess!
67. The confusion is IPC can’t settle on name for grease interceptors
IPC/UPC 2000 & 2003 called them Grease Traps tested to PDI-101
IPC 2006 and 2009
2. Grease Interceptors
2012 IPC finally changes these to “Hydromechanical”
2. Automatic Grease Removal Device
(there is no name for the most popular “outdoor” Grease Interceptor)
UPC 2006 and 2009
9. Hydromechanical Grease Interceptors

IPC-Grease Interceptors
The mechanical grease trap is
often installed in a kitchen area by
the sink (but should be designed
away from any food handling)
Key! Flow control
devices (orifices)
Serviced by the kitchen employees
rather than professionals
Manufactures recommend daily
cleaning due to the small size
PDI – G101 Tested
76. Gravity Grease Interceptors (no flow control)
#1 Principle for separation:
Retention Time
Retention 12 – 30 mins.
Cool-down of grease in water

85. Restaurant Grease Interceptor Application
Kitchen sinks, dishwashers, soup
kettles, handwashing sinks, mop sinks
and floor drains should be piped to the
grease interceptor located at least 10’
away.
Water temperature must be less than
120 degrees
