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 1000Now add 10 What is the total?
Did you get 5000?
Building a “Green” WorldTakes Everyone Working as a Team
…and seems to be the focus of every city
Park Environmental Equipment
Household wastes drain directly into
Sanitary Sewer with no additional
treatment.
Public Awareness is the onlySolution!
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?
Who is paying for the program?
SSOs New Issue Past 3 years
EPA Inspectors are looking close-typically find grease problems(Tulsa was fined $250k by EPA for SSO’s?)

Grit/Oil Interceptors now required at Parking Garagesfor power washing operations
Grit/Oil Interceptor
If no Grit/Oil Interceptor is installed, Power Washers must vacuum up & transport all water dispensed.
OKC SWQ issues a permit and registration certificate after the applicant pays all applicable fees. Good for 1 year

Elevator Separators – now in IPC-2006, 09’
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.

Planning for Decontamination Wastewater
From Homeland Security – Post 9/11Plan to Design for:
•Chemical Warfare Agents•Biological Disease•Radioactive Materials•Compounds used in the decontaminations process
Where does this Wastewater Drain?
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
OSHA Regulations

Basics of All Sanitary 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
Acid Neutralizing Devices
IPC, UPC 2006, 09, 2012 have updated straight forward language on Acid Neutralization
Found under Indirect Wastes in Chapter 8 of the plumbing codes

“We’ve heard the codes are all alike now”
Nearly all Tx, Ok, Ak, La Cities are
IPC, 2000, 2003, 2006 or 2009
San Antonio - Adopted IPC January 2010
(Watch Amendments though - UPC)
Austin - Still UPC
Houston - Still UPC
(Watch Amendments though - IPC)
So, what’s the confusion?
1. Grease Trap2. Mechanical Trap3. Grease Interceptors4. Automatic Grease Removal Device (GRDs)5. Gravity Grease Interceptors6. Hydromechanical Grease Interceptors7. New! FOG Interceptors
A Confusing Mess!
Confusion over Names of Grease Traps
Grease Interceptors Names IPC & UPC since 2000
IPC 2006 and 20091. 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
1. Hydromechanical Grease Interceptors2. Gravity Grease Interceptors
IPC 20151. FOG (Fats, Oils, and Greases) System
The confusion is IPC can’t settle on name for grease interceptors IPC/UPC 2000 & 2003 called them Grease Traps tested to PDI-101
What happen to the ole Concrete Grease Trap by
???
“They picked everyone but us?”
IPC 2006 & 2009
Cities have to amend the Codes
The “Fallout” when this happens…
Hydromechanical 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

#1 Principle for separation:Retention Time

Cross Connection Control When and why do Civil Engineers specify
Backflow Assemblies?
Why and Who? It’s the law
Water PurveyorHealth DepartmentPlumbing Official (approves engineered designs)Manufacturer (provides tested and right type assembly)Consumer (continued testing by certified backflow tester)
Two Types of Backflow
2. Back Siphonage - Loss of pressure below Atmospheric Pressure (water hose left in soapy water bucket)3. Back Pressure – any elevation of pressure in the downstream piping (by pump, elevation of piping, or stream and/or air pressures
Types of Backflow Preventers
Air Gap Vacuum Breaker Double Check Detector Check Reduced Pressure Principle
Air GapBackflow Preventer Types
Vacuum Breakers
Two Types: Atmospheric & Pressure Type (testable)
Used on on Non-Potable Water Applications Where it is Not Subject to Backpressure
Backflow Preventer Types
Double Check Backflow Preventer Used on closed loop systems
typically on fire service lines
Where no other access to water for pubic use may be accessed (valves, hose closets, etc)
Backflow Preventer Types
Detector Check Backflow Preventer Similar to the Double
Check Backflow except with Detector Meter to Detect Unauthorized water use and leakage.
Detector meters detect usage of 5 gpm or less.
Fire hydrants, hose cabinets, break tanks, construction sights.
Backflow Preventer Types
Reduced Pressure Zone Backflow Preventer(RPZ)
When contaminants could be a Toxic or Hazardous
Chemical Plants Funeral Homes Schools (labs) Cities are requiring in
more and more applicationsRelief Valve
