The rules

What a pumper in Oklahoma should know.

A guide, not legal advice. Counties and local health departments can add their own rules on top of the state's, so check with the county where the system is.

Who regulates septic systemsRun by the state

Oklahoma Department of Environmental Quality, Environmental Complaints and Local Services (ECLS) Division, On-Site Sewage Programs. DEQ's ECLS Division runs the on-site sewage programs and brings DEQ programs to the local level through its local environmental specialists; DEQ also licenses septage pumpers and transporters.

The state program
Pumper and hauler licensingState license

Any business that pumps, transports or disposes of septage must hold an annual DEQ license (OAC 252:645-1-3). Initial applicants complete two hours of DEQ training and pass an exam with at least 70 percent, and drivers employed or contracted by a licensee need driver certification. Each vehicle must be inspected by and registered with DEQ every year (252:645-1-4), and the application includes an inspection report signed by the local DEQ representative and proof of an approvable disposal option. Licenses expire January 31 and renewal requires two hours of approved renewal training.

Licensing details
Where septage can go

Septage from holding tanks, portable toilets and marine sanitation devices must go to a permitted wastewater treatment facility or a city-permitted pretreatment facility; other septage may go only to a publicly owned treatment works, a permitted land application site, a permitted municipal solid waste landfill, a permitted septage treatment facility, or a city-permitted pretreatment facility (OAC 252:645-1-7).

Disposal rules
Records and reports

Licensees must keep a daily log for each registered vehicle (manifests or invoices may be used) showing septage pumped and where it was taken, the pump location, the storage or disposal site, and the driver (OAC 252:645-1-6). Records must be kept three years, and licensees with a land application permit include their land application records with the annual renewal.

Questions

Do I need a license to pump septic tanks in Oklahoma?

Oklahoma requires a state license or permit to pump or haul septage. Any business that pumps, transports or disposes of septage must hold an annual DEQ license (OAC 252:645-1-3). Initial applicants complete two hours of DEQ training and pass an exam with at least 70 percent, and drivers employed or contracted by a licensee need driver certification.

Licenses expire January 31 and renewal requires two hours of approved renewal training.

Where do I get Oklahoma septic forms?

From the state's own pages, linked on this page. Many counties and local health departments use their own forms on top of the state's, so check with the county where the system is too.

Does PortaPro come with Oklahoma forms built in?

No. Forms change, and counties use their own, so PortaPro doesn't ship copies. You upload the current PDF from your county or state once, place the fields on it, and PortaPro fills it from each job: customer, site, tank, gallons pumped and technician. When the agency updates its form, you upload the new one.

How current is this page?

We read the official sources listed at the bottom on October 8, 2026. Rules and forms change, so treat this as a starting point and confirm with the agency before you rely on it. This is not legal advice.
