Three in four US city markets with a listed grease trap provider have only one. Across 1,747 licensed providers in 1,016 US city markets, 760 markets (75%) have a single listed provider, and just 39 have six or more. Half of all listed providers sit in only ten states.
Published 19 July 2026 · GreaseTrapLocator editorial team · Data as of 19 July 2026
Grease trap servicing is a licensed, locally regulated trade, and there is no official national register of who performs it. To get a picture of how provider coverage is actually distributed, we analysed every licensed provider listed in the GreaseTrapLocator directory: 1,911 providers — 1,747 across the United States and 164 across Canada. The finding that stands out is not the national total, but how thinly it is spread.
What this measures: the number of licensed grease trap service providers listed in the GreaseTrapLocator directory, counted by state/province and by city market, as of 19 July 2026. A “city market” is a unique city-and-state pair (so Springfield, Illinois and Springfield, Missouri count separately).
What this does NOT measure: the total number of grease trap operators in existence. This is directory coverage, not a census. Providers who are not listed with us are not counted, so real provider counts in any given market may be higher. Counts should be read as a floor, not a total.
How providers qualify: listings cover companies performing grease trap and FOG services (cleaning, pumping, interceptor service, used cooking oil collection). Septic-only operators are excluded from the directory.
Reproducibility: figures are aggregated directly from the live directory on the date shown. We re-run this index periodically; cite the date with the figure.
Finding 1: Most markets have a single provider
Of the 1,016 US city markets where at least one licensed provider is listed, 760 (75%) have exactly one. Fewer than 4% of markets have six or more.
| Listed providers in market | US city markets | Share |
|---|---|---|
| 1 provider | 760 | 74.8% |
| 2 providers | 115 | 11.3% |
| 3–5 providers | 102 | 10.0% |
| 6+ providers | 39 | 3.8% |
Base: 1,016 US city markets with at least one listed provider, 19 July 2026.
Finding 2: Half the providers are in ten states
Provider coverage is heavily concentrated. California, Texas and Florida alone account for 527 providers — 30% of the US total. The top ten states account for 899 providers, just over half (51%).
| State | Listed providers | Cities covered |
|---|---|---|
| California | 214 | 90 |
| Texas | 169 | 90 |
| Florida | 144 | 64 |
| North Carolina | 73 | 46 |
| Massachusetts | 60 | 48 |
| New York | 59 | 33 |
| Arizona | 49 | 14 |
| Tennessee | 45 | 20 |
| South Carolina | 44 | 37 |
| Michigan | 42 | 30 |

Finding 3: Ten jurisdictions have fewer than ten providers
At the other end, 10 of the 51 US jurisdictions (50 states plus Washington DC) have fewer than ten listed providers each. In these markets an operator facing a failed interceptor may have very few licensed options within reach.
| Jurisdiction | Listed providers | Cities covered |
|---|---|---|
| District of Columbia | 2 | 1 |
| Alaska | 3 | 2 |
| Delaware | 4 | 4 |
| Wyoming | 5 | 4 |
| South Dakota | 5 | 3 |
| North Dakota | 6 | 4 |
| West Virginia | 6 | 6 |
| Montana | 9 | 8 |
| New Mexico | 9 | 4 |
| Vermont | 9 | 9 |
Canada: 164 providers across eight provinces
Canadian coverage follows the same pattern, concentrated in Ontario and British Columbia.
| Province | Listed providers | Cities covered |
|---|---|---|
| Ontario | 68 | 33 |
| British Columbia | 36 | 20 |
| Alberta | 21 | 7 |
| Quebec | 14 | 10 |
| Saskatchewan | 12 | 2 |
| Nova Scotia | 5 | 4 |
| Manitoba | 5 | 3 |
| New Brunswick | 3 | 3 |
Why this matters
Standard guidance for any grease trap service is to compare at least two quotes before signing a recurring agreement. In a market with one listed provider, that is difficult. Thin local coverage also matters during a failure: an overflowing interceptor is a same-day problem, and travel distance is one of the factors that pushes emergency pricing up. See the grease trap cleaning cost guide for how access and urgency affect pricing, and grease trap regulations by state for the compliance obligations that apply regardless of how many contractors operate locally.
For municipal FOG and pretreatment programs, provider density is a practical constraint on enforcement: a cleaning cadence is only realistic if licensed haulers are available to meet it.

Frequently Asked Questions
How many grease trap service providers are there in the US?
There is no official national register of grease trap service providers. This index covers 1,747 licensed providers listed in the GreaseTrapLocator directory across all 50 states and Washington DC as of 19 July 2026, plus 164 across eight Canadian provinces. It measures directory coverage, not the total size of the industry.
Which states have the most grease trap service providers?
California (214), Texas (169), and Florida (144) lead by a wide margin, together accounting for 30% of all listed US providers. The top ten states account for 899 providers, just over half the US total.
How many US markets have only one grease trap provider?
Of the 1,016 US city markets where at least one provider is listed, 760 (75%) have exactly one. Only 39 city markets have six or more listed providers, meaning most operators outside major metros have little or no local choice of contractor.
Why does single-provider coverage matter for restaurants?
Where only one licensed provider serves a market, operators have limited ability to compare quotes and fewer options during an emergency call-out. Comparing at least two quotes is standard advice, which is harder in a single-provider market.
