An MSD-approved hauler comes to your property, pumps the trap or interceptor to 100% capacity, inspects for damage, and verifies that grease levels are within MSD limits. Every service includes a waste manifest documenting proper disposal at an approved facility.
MSD Ordinance No. 8472 requires all food service establishments in St. Louis City and County to install grease control devices, register with the FOG program, and keep traps cleaned to within MSD capacity limits. The standard minimum is every 90 days — high-volume kitchens may need monthly service.
St. Louis has dual enforcement that catches many restaurant owners off guard. MSD handles sewer compliance, but the health department also reviews grease trap maintenance during their bi-annual food safety inspections. A violation with either authority means separate penalties.
MSD explicitly prohibits degreasers, enzymes, and similar substances that temporarily emulsify grease. These products do not eliminate grease — they push it downstream into the sewer system where it causes blockages and environmental violations. Using hot water to flush grease lines is also prohibited. Only mechanical cleaning by a licensed hauler counts.
MSD requires 3 years of records on-site and available for inspection: service dates, cleaning descriptions, waste manifests from licensed haulers, repair records, and all correspondence with MSD. We provide every piece of documentation you need with each visit.
All food service operations must register with MSD's FOG program by submitting a Sewer Use Customer Application and Food Service Operation Form. Grease trap design must be submitted to MSD for approval before installation. We can guide new establishments through the full registration process.
| Establishment Type | Required Frequency |
|---|---|
| High-volume restaurants (fast food, fried food) | Monthly |
| Standard restaurants and commercial kitchens | Every 90 days (quarterly) |
| Lower-volume food service (cafes, delis) | Quarterly minimum |
| All establishments regardless of schedule | When 25% grease depth OR 60% capacity reached |
| First FOG violation | Starting at $1,000 |
| Repeated violations | Escalating fines (substantially higher) |
| Failure to maintain grease trap | Emergency shutdown orders |
| Causing sewer system damage | Full financial liability for repairs |
| Significant non-compliance | Published publicly (40 CFR 403) |
| Health department violation | Separate fines + potential closure |
Pricing depends on trap type, size, and accessibility. Under-counter traps start at $150. In-ground interceptors run higher based on gallon capacity. Quarterly service contracts reduce per-visit costs significantly and include automatic scheduling so you never miss a 90-day window.
Emergency and same-day service is available throughout the metro for situations where grease levels have exceeded MSD limits and you need service before an inspection.
They set us up on quarterly service and we haven't thought about MSD compliance since. Manifests filed automatically every time.
Our in-ground interceptor hadn't been cleaned in 6 months. They got us back under the 25% depth threshold in one visit and filed our manifest the same day.
We just opened and had no idea about the FOG program. They walked us through MSD registration, sized our trap, and got us on a cleaning schedule.
