Exactly. The City of Vancouver is currently conducting a pilot test on a device called a “multiceptor” that is supposed to be able to treat high-FOG black water from multi-family housing with a minimum of plumbing retro-fit. We have one installed in the main lateral coming from a high-density multi-family housing development.  The study is in process so the jury is still out on whether this does the job in a cost effective manner.  And yes, the project is being handled by our pretreatment group. I’m sure the manufacturer would love to talk to anyone else who might be having similar problems. 

 

To date we have found that targeted outreach rather than additional regulation is the most effective tool for addressing FOG.  A few full-color photos of clogged interceptors and sanitary sewer overflows along with some “Can the Grease” kits (flyer and a tin can to collect grease) can be very effective. The Grease Goblin program in NC was the basis for our initial program materials.  Los Angeles also has a strong FOG program.

I’m not sure how that would work in the real world since, in a commercial (restaurant) setting, the plumbing is designed so that all “domestic” wastewater enters the sewer service lateral downstream of the grease trap. There would be a significant additional expense due to the need for parallel wastewater piping systems throughout each building. The only other alternative I can think of would be an under-sink grease trap in each kitchen, but the odds of such an arrangement being properly maintained would be pretty slim. Besides, this arrangement would be extremely impractical for both the apartment manager and the local regulators.

 

Which brings to mind another issue: would those apartment buildings with grease traps fall under the federal industrial pretreatment regulations with all associated requirements for reporting and record keeping? I would wear body armor if I had to present this idea at an advertised public meeting.

Hello everyone,

I am trying to find code language requiring grease interceptors for multi-family apartment buildings. Does anyone have an example of a city or county that has approved such a requirement and/or example code language?

Thank you for your time,
