Now add another 1000 . Now add30.Add another 1000. Now add 20. Now add another 1000Now add 10 What is the total?Did you get 5000?
Building a “Green” World Takes Everyone Working as a Team…and seems to be the focus of every city
Park Environmental EquipmentHousehold wastesdrain directly into Sanitary Sewerwith no additional treatment.Public Awareness is the only Solution!
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?
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…

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

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 10.Gravity Grease Interceptors IPC 2015 1. FOG (Fats, Oils, and Greases) System

The “Fallout” when this happens… Cities have to amend the Codes
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

Cross Connection ControlWhen and why do Civil Engineers specify Backflow Assemblies?
Why and Who? It’s the lawWater 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
Backflow Preventer TypesVacuum Breakers Two Types: Atmospheric & Pressure Type (testable) Used on on Non-Potable Water Applications Where it is Not Subject to Backpressure
Backflow Preventer TypesDouble 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 TypesDetector 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.
