interceptors & separators

OK plumbers, I’m on Chapter 10 in IPC which is Traps, Interceptors, & Separators. What I’m looking and asking for is a definition or difference between the three. I know the trap answer. Please explain it to me as if I’m a 6 year old. Thank you gentlemen.

Hi Dylan,

interceptors and separators are basically the same thing and have multiple types, for example grease traps in resturant kitchens, or gravel seperators as used in car wash drains.

They are basically there to seperate water that can safely flow back into the waste system from anything that requires further specialised treatment.



So a grease trap is technically a separator right? I’m surfing for some decent images with flow in diagrams.

That’s right a grease trap is a separator

Actually a septic tank is also a separator when you think about it


try this one Dylan

That one works Gerry, sweet. So most collection methods are going to be third party then? Obviously we can’t be allowing the chemicals to enter the municipal drain.

I’m reading about some of them having internal treatment. The question this brings up is after treatment, can it then go to the municipal drain or does it get privately collected?

Tonight’s class will put the pieces together, I’m just getting an idea before the lecture.

Thanks Gerry

Other than septic systems I can only think of some industrial processes which would include internal treatment and those would be very highly regulated, in most cases the seperated materials would be treated as Hazardous.



Dental clinics and hospitals often have separators in use.

Thank you gentlemen. I just got out of class and can honestly say I grasp this completely now. In fact, if there are any questions you guys have, ask me while its fresh.
