Local License Index

Clerk file of septic licenses. No ads. No maps. No quotes.

How we verify

Each listing is a record we can point at. A maintainer opened a government page or PDF, quoted the name and (when printed) the license number from that page, and wrote the date. Directory sites, LILWA membership, Angi, and ads are not a license source.

If a roster does not print a number, the license field is the phrase that is true — for example “not printed on published town roster” — not a guessed ID.

Suffolk County, New York

Primary live lookup: Suffolk County Department of Labor, Licensing and Consumer Affairs Liquid Waste License search, ca.suffolkcountyny.gov/dcasearch. Accela Citizen Access Consumer Affairs module is cited as a second door to the same county records.

Supporting county artifact: Suffolk County Septic Improvement Program Approved List of SIP Installers, ranking PDF revised 11/06/2025. County FAQ states SIP vendors hold a Liquid Waste License. SCDHS Office of Wastewater Management will not inspect an install without a valid liquid waste license.

NYS DEC Part 364 numbers that appear only on a company site are labeled company-published, not DART-verified. The DART search is a JavaScript wall.

Nassau County, New York

Primary live lookup: Nassau County Department of Consumer Affairs Search Businesses With Valid Licenses (Home Improvement), apex5.nassaucountyny.gov/ords/f?p=288:500:::NO. The number on the page is a Home Improvement ID, not a Suffolk-style LW. Installers in the county I/A grant program must hold that license.

Supporting county artifact: Nassau County Soil & Water Conservation District S.E.P.T.I.C. participating designers/installers PDF updated 7/29/2024. That PDF prints name, street, and phone. It does not print the Home Improvement number. Program page: nassauswcd.org/SEPTIC (approximately 40,000 residential North Shore cesspool/septic properties). South and central Nassau is mostly sewered; this file does not pad with sewer-only towns.

Barnstable County, Massachusetts

MassDEP does not license septage pumpers. Town Boards of Health do. Primary pumping source for this seed: Town of Harwich Health Department Licensed Septic Haulers roster updated 01.30.2026 (Harwich CivicPlus asset). Town of Harwich Licensed Septic Installers (updated 10.02.2025) is used only to add install when the same firm is on that list. Town of Dennis 2023 hauler/installer PDFs are used for ZIP and city corroboration, not as the live license date.

Those town rosters print name, street or PO Box, and phone. They do not print a permit number. We do not invent one.

Plymouth County, Massachusetts

Same MassDEP rule as Barnstable. Quote from the consumer-protection guide (opened 2026-09-02): “To find a licensed septage pumper/hauler, contact your local Board of Health. MassDEP does not license or certify septic-system pumpers or recommend any company.”

Town lists opened this pass:

Plymouth and Kingston rosters print name, street or PO Box, phone, and (Kingston) ZIP. They do not print a permit number. Duxbury prints a permit number; that number is quoted only for firms on the Duxbury list. Streets outside Plymouth County, PO Box-only rows, Cape HQ firms already in Barnstable, and generic installer-only excavators are omitted. Brockton is not padded as sewer-only.

Bristol County, Massachusetts

Same MassDEP rule as Barnstable and Plymouth. Quote from the consumer-protection guide (opened 2026-09-02): “To find a licensed septage pumper/hauler, contact your local Board of Health. MassDEP does not license or certify septic-system pumpers or recommend any company.” No county-wide tank count was opened this pass. Urban mill cities (Fall River, New Bedford, Taunton) are sewered; Westport / Dartmouth / Rehoboth / Freetown-style towns are not. A firm is listed only when a fetchable 2024–2026 town hauler list names it and a printed street is in Bristol County.

Town lists opened this pass:

Westport and Dartmouth/North Attleborough hauler rosters do not print a permit number. Streets outside Bristol County, PO Box-only rows, Cape/Plymouth HQ already listed, portable-toilet-only rows, and towns that publish only an application PDF are omitted. Fall River / New Bedford / Taunton sewer cores are not padded.

Ocean County, New Jersey

Septic waste is solid waste in New Jersey. NJDEP pages advertise a live DataMiner report, Solid Waste Transporters (A-901 Approved): Transporters - A-901 Licensed - Solid Waste. Landing pages opened this pass: dep.nj.gov/wastecompliance/transportation-of-waste/ and dep.nj.gov/dshw/forms-and-info/ (item 28). The DataMiner report itself did not open this pass (timeout / empty body / 403). A-901 numbers are not invented.

Fallback government PDF actually opened: NJDEP residual-waste haulers phone list (names, streets or PO Boxes, cities, phones; PDF created 2012-11-15): waste-haulers-phone-numbers.pdf. That list does not print an A-901 number. A firm is listed only when that PDF names it with an Ocean County street (not PO Box-only). ZIP is from a U.S. Census Bureau geocoder match of the printed street; the haulers list does not print ZIP.

Tank count (official property inventory, not a pumper roster): Ocean County Wastewater Management Plan components PDF, filename 20200326 (Acrobat 2020-04-16): Ocean County Health Department + Planning inventory of approximately 30,000 individual subsurface disposal systems. Quote: installation of new ISSDSs is “increasingly uncommon”; remaining systems in rural pockets including Eagleswood, Jackson, Lakewood, Little Egg Harbor, Manchester, and all of Plumsted outside Joint Base McGuire-Dix-Lakehurst / Pinelands. PDF: 20200326-ocean-county-wmp-components.pdf.

Gwinnett County, Georgia

Georgia Department of Public Health, Environmental Health Section, certified septic-tank company rosters dated 8/28/2026:

DPH FAQ: company certifications expire 2/28 of even years. The public list does not print certificate numbers. One Gwinnett firm publishes a number on its own site; that number is labeled company-published. Streets are not on the DPH PDF; they come from an opened company page or an FMCSA SAFER snapshot that matched the DPH name and phone. Royal Flush Plumbing — Snellville is on the installer PDF only, so pumping is not claimed.

Marion County, Florida

Primary live lookup: Florida DEP Operator Certification Individual Septic Certification Search (License Number field), prodapps.dep.state.fl.us/ocp/reports/accesspublic/OSP/Search_form.

Dukes County, Massachusetts

Same MassDEP rule as Barnstable, Plymouth, and Bristol. Quote from the consumer-protection guide (opened 2026-09-02): “To find a licensed septage pumper/hauler, contact your local Board of Health. MassDEP does not license or certify septic-system pumpers or recommend any company.”

Tank / unsewered share (Martha’s Vineyard Commission, Stormwater and Wastewater Management): wastewater from about 1,800 properties is treated at one of the Island’s five wastewater treatment plants (Edgartown, Oak Bluffs, Tisbury, Airport, and Wampanoag Tribal Housing); over 14,000 Vineyard properties (more than 90%) treat wastewater on site — cesspools, older septic systems, or newer Title 5 systems. Magazine-range “6,000–10,000 tanks” is not used. Nantucket was not separately inventoried. Landing: mvcommission.org/stormwater-and-wastewater-management.

No county-wide hauler PDF was found. Licensing is town-by-town (Tisbury, Oak Bluffs, Edgartown, West Tisbury, Chilmark, Aquinnah, plus Gosnold). This pass opened town Board of Health pages, fee schedules, application forms, one Oak Bluffs wastewater-department installer PDF (sewer, names/phones only), and Oak Bluffs 2024–2026 minutes that name licensed haulers without streets.
