Oak Harbor, WA — Restaurant CBSM Campaign
Oak Harbor’s wastewater team had been seeing chronic grease loading from a cluster of commercial kitchens. Enforcement letters weren’t moving the needle. We built a brochure-led CBSM intervention instead.
What we did
- One-on-one operator brochure with a 5-step grease-trap routine.
- Multilingual (English + Spanish + Korean — matched the operator demographics).
- Distributed by health inspectors during their routine visits (not mailed cold).
- Follow-up postcard at 90 days.
Result
Reportable grease loading dropped meaningfully across the cluster within two quarters. The campaign has since been adapted for two neighboring utilities.
