Start with the facility and project
Philadelphia's plumbing provisions require a grease interceptor or automatic grease-removal device where covered food-preparation fixtures and equipment discharge grease-laden waste. PWD's Industrial Waste Unit says exact installation and sizing requirements are issued project by project while a plumbing permit is obtained through Licenses and Inspections.
Confirm new, replaced, or altered interceptor work with L&I and PWD before construction. Do not select a device or schedule from a generic national table.
Set maintenance from the actual equipment
The City materials reviewed call for accessible equipment, periodic checks, and regular full pump-out, but they do not publish one universal quarterly, monthly, or 25%-capacity rule for every Philadelphia food establishment. Set the interval from the approved equipment, operation, observed accumulation, service history, and any site-specific City direction.
Keep signed service records and any compliance or best-management-practice records required for the facility. Users subject to applicable PWD pretreatment requirements must retain related records for at least three years; confirm the exact site-specific records with PWD.
Document a lawful disposal route
Ask the contractor to document the work and the lawful handling and disposal route for removed material. Philadelphia's current hauled-wastewater rules say grease-trap waste may not be discharged through the City's septage route. Do not rely on a claim that a provider uses a PWD-approved grease-waste facility unless PWD confirms that specific arrangement in writing.
Compare written service quotes
The City does not publish contractor market prices. Compare the written scope, actual device and access, work included, schedule, emergency availability, documentation, handling route, exclusions, insurance, applicable job credentials, and total price.
Backups, persistent odors, slow drainage, visible discharge problems, or pest activity should prompt assessment, but they do not prove a particular threshold or legal violation. Avoid providers that promise a City approval, price discount, response time, or fine outcome without written support.
A practical facility checklist
- Confirm installation, replacement, or altered plumbing work with L&I and PWD before construction.
- Use the approved equipment, actual accumulation, and service history to set maintenance.
- Keep signed service records and any site-specific pretreatment or BMP records PWD requires.
- Ask the contractor to document a lawful handling and disposal route.
- Compare itemized quotes without treating a provider as City-approved unless that status is verified.
