Commercial Grease Interceptor Requirements in Cleveland

Commercial kitchens in Cleveland send fats, oils and grease (FOG) down drains every service. When that FOG hits the sewer above local limits — or when a plans examiner and the sewer authority require pretreatment — the building needs a grease interceptor sized and installed under the plumbing code, not a shop-sink "trap" chosen from a catalog at the last minute. This post explains what Cleveland's sewer-use code and the Ohio Plumbing Code actually say, so owners and tenants know what to prepare before a kitchen build-out or a correction letter arrives.

This is informational. It is not a substitute for the city's review of your plans, and it is not a quote. ACC coordinates commercial plumbing after a walkthrough; call (216) 480-8899.

The Short Answer

• Cleveland caps FOG at 100 mg/l at the point of discharge into the sewer system (Codified Ordinances § 541.11).
• The Commissioner can require a grease, oil or sand interceptor where applicable, and can require pretreatment plans to be approved before installation (§ 541.12).
• Ohio Plumbing Code Chapter 10 (OAC 4101:3-10-01) says interceptors are required where the local sewer purveyor requires them, or as otherwise required in that section; Ohio EPA rules may also apply to pretreatment devices.
• The owner maintains required pretreatment in good working order at the owner's expense and must notify the Commissioner if the facility cannot comply.
• Quote after a walkthrough. ACC does not invent a grease-trap price on this page.

What Cleveland's Sewer Code Bans

Cleveland Division of Water Pollution Control administers Chapter 541 (Sewer Connections and Sewer Use Code). Section 541.11 lists discharges that are unacceptable and prohibited. For kitchens, the line that matters most is § 541.11(b)(4):

• Water or waste containing fats, wax, grease or oils, whether emulsified or not, in excess of 100 mg/l; or
• Substances that may solidify or become viscous at temperatures between 1°C and 65°C at the point of discharge into the system.

That limit is measured at discharge into the system — not at the fryer. A kitchen that "has always poured grease down the three-compartment sink" can still violate the ordinance even if no interceptor has ever been written up before. Cleveland Water Pollution Control is a division of the Cleveland Department of Public Utilities and is separate from the Northeast Ohio Regional Sewer District (NEORSD); both can matter for sewer use, but Chapter 541 is the city's own code.

When the City Can Require a Grease Interceptor

Section 541.12 gives the Commissioner tools when unacceptable discharges are occurring or proposed:

1. Prohibit the continued or proposed discharge.
2. Require on-site modifications to reduce or eliminate the discharge.
3. Require pretreatment or storage for flow equalization.
4. Where applicable, require the installation of grease, oil or sand interceptors.
5. Take other remedial action the Commissioner deems necessary.

If pretreatment is required, § 541.12(c) adds process rules that owners miss:

• Plans first. Plans, specifications and related data for pretreatment or flow-equalization facilities must be submitted for review and approval before implementation. Later alterations also need prior notice and approval.
• Approval is not a free pass. Even after Commissioner approval, discharges must still comply with all governmental authorities that have jurisdiction over unacceptable discharges.
• Owner-paid maintenance. Facilities must be kept in good working order and operated efficiently by the owner at the owner's expense.
• Immediate notice on failure. If a facility does not or cannot comply, the owner or person responsible must immediately notify the Commissioner so action can be taken to protect people, property and the sewer system.

How the Ohio Plumbing Code Fits

Ohio Administrative Code rule 4101:3-10-01 adopts Chapter 10 of the International Plumbing Code, 2021 edition, with Ohio modifications. Two modifications matter for kitchens:

• Scope. The chapter governs traps, interceptors and separators installed inside a building (not on the building sewer). The rule states that Ohio EPA rules may also govern the design and installation of pretreatment devices such as traps, interceptors and separators.
• When interceptors are required. Section 1003.1 is modified so that interceptors are required where required by the local sewer purveyor or as otherwise required in that section — not as a blanket "every restaurant automatically" rule written into a marketing page.
• Food-processing plants. A new section 1003.1.1 sends wastes from industrial processes, meat packing and food processing facilities to Ohio EPA rules or the authority in charge of the sewage system (citing R.C. 6111.44 and 6111.45).

Practical takeaway: sizing, type (hydromechanical vs gravity), location and venting belong in drawings that both the plumbing plans examiner and, when required, Water Pollution Control can accept. Do not treat a supplier's "typical restaurant size" as the legal answer for your address.

A Practical Sequence Before You Buy Equipment

1. Confirm the use. New food service, change of use, or an existing kitchen under a correction letter? The paperwork path differs.
2. Read the discharge rules. Start with Cleveland §§ 541.11 and 541.12 if the building is in the City of Cleveland, and ask whether NEORSD or another sewer authority also has conditions for the site.
3. Get plumbing drawings. Fixture schedule, drain lines that will carry grease-laden waste, interceptor location, access for cleaning, and venting.
4. Submit pretreatment data when required. If the Commissioner requires pretreatment, § 541.12 says plans go in for approval before installation — not after the concrete is poured around an undersized unit.
5. Pull the plumbing permit. Cleveland Codified Ordinances Chapter 3133 requires a permit from the Commissioner for plumbing work (with limited exceptions for minor repairs). Interceptor work is not a "fixture swap" you hide behind a cabinet.
6. Plan maintenance access. An interceptor that cannot be opened, pumped or inspected will not stay in compliance even if the original install passed.

If you are unsure whether existing piping can support a kitchen change, start with a commercial plumbing walkthrough rather than ordering equipment first.

Mistakes That Turn Into Stop-Work or Costly Rework

• Installing first, submitting plans later. § 541.12 requires approval before pretreatment facilities are implemented.
• Assuming "we have a trap under the sink" equals compliance. The ordinance cares about discharge concentration and, when required, an approved interceptor — not the presence of any under-sink box.
• Closing access panels. Maintenance is the owner's duty. Blocking cleanouts or burying a unit without access invites the next failure notice.
• Ignoring a lease clause. Many commercial leases assign FOG compliance, pumping and repairs to the tenant. Settle who pays before the walkthrough, using the lease — not a verbal assumption. See our commercial lease plumbing repairs post.
• Skipping the plumbing permit. Chapter 3133 still applies to drainage and plumbing alterations inside the building.

How ACC Helps

ACC Solutions coordinates commercial plumbing for Cleveland kitchens and other grease-producing spaces. We partner with plumbing companies, walk the building, and quote the plumbing scope after we see the existing drains, proposed fixtures and any city letters. We do not publish grease-interceptor package prices here because sizing and site conditions drive the work.

Frequently Asked Questions

Does Cleveland limit grease in sewer discharges?

Yes. Cleveland Codified Ordinances § 541.11 prohibits discharging water or waste containing fats, wax, grease or oils (whether emulsified or not) in excess of 100 mg/l, or substances that may solidify or become viscous between 1°C and 65°C, at the point of discharge into the system.

Who can require a grease interceptor in Cleveland?

Under Cleveland Codified Ordinances § 541.12, if unacceptable discharges (including excess grease) are discharged or proposed, the Commissioner of Water Pollution Control may, where applicable, require the installation of grease, oil or sand interceptors, require pretreatment, prohibit the discharge, or order other remedial action. Plans for required pretreatment facilities must be submitted for review and approval before they are installed.

Does the Ohio Plumbing Code always require a grease interceptor?

Ohio Administrative Code 4101:3-10-01 modifies Ohio Plumbing Code section 1003.1 so that interceptors are required where the local sewer purveyor requires them, or as otherwise required in that section. The same rule notes that Ohio EPA rules may also govern pretreatment devices such as traps, interceptors and separators. Confirm what Cleveland Water Pollution Control and your plans examiner require for the specific kitchen.

Who maintains a required grease interceptor?

Cleveland Codified Ordinances § 541.12(c)(2) says pretreatment and flow-equalization facilities must be maintained in good working order and operated efficiently by the owner at the owner's expense, and must comply with the chapter and other applicable rules. If a facility cannot comply, the owner or person responsible must immediately notify the Commissioner.
