Mississippi Septic Contractor License Requirements (2026)
By Gabriel Giner, Editor · Source checked 2026-09-30
Mississippi certifies onsite wastewater installers through the State Department of Health. Its installer rules address training, examination, insurance, and annual certification. Certification as a professional evaluator or pumper is a different role and should not be substituted for installer authority. Use the installer-specific application and the approved site documents for the system to be constructed.

Eligibility Requirements
This guide does not establish a minimum applicant age; confirm any age requirement with the issuing authority. Check the current application for identification and tax-number requirements. Use the current application for identification and address requirements; out-of-state work history does not itself authorize work here.
Good moral character
Complete the disclosures required by the applicable application. No additional character standard is inferred from a permit or program summary.
Background investigation
Confirm any applicant screening with the issuing authority. The cited sources are not used to infer an unlisted fingerprint requirement.
Experience and Education
Complete the installer training, application, and examination process. Rule 2.1.28 requires liability coverage and payment of the annual certification fee. Supply the required insurance and fee documentation within the post-examination period specified by MSDH.
Accepted proof of experience or eligibility
- Current application for the credential or local authorization described above.
- Supporting qualification records required by that application; retain approvals for the actual work scope.
Exam Requirements
Testing provider or authority: Mississippi State Department of Health. The following examination requirements cover the pathways described in this guide; follow each part's classification, waiver, and local-scope conditions. Unpublished format details do not remove an examination requirement:
- Certified onsite wastewater installer examination — question count: confirm with the authority, timing: confirm with the authority, passing score: confirm in the current candidate bulletin
Examination fee: No complete current examination charge is established here; confirm the applicable assessment and provider.
MSDH’s installer certification process includes an examination. Obtain the current course schedule and testing instructions; this guide does not establish an examination question count or testing price.
Insurance and Bonds
No single applicable bond amount is established in this guide. Confirm the business, credential, and project requirements; an unspecified amount is not a bond exemption.
General liability
Installer rules require at least $50,000 liability coverage per occurrence and $100,000 aggregate.
Workers' compensation
Confirm employee coverage obligations separately; the septic program sources do not establish a workers’ compensation exemption.
Fee Schedule
The reviewed sources do not establish a complete current fee schedule for this pathway. Obtain the current application and renewal amounts from the issuing authority. Local project charges, training, insurance, and business costs are separate; unspecified amounts are not zero-cost exemptions.

Step-by-Step Application Roadmap
- Identify the applicable installer pathway. Installer, professional evaluator, and pumper rules appear in the same regulations but authorize different work.

- Complete the applicable assessment and filing. MSDH’s installer certification process includes an examination. Obtain the current course schedule and testing instructions; this guide does not establish an examination question count or testing price.
- Obtain the project approvals. Identify the permitting authority for the property, secure the required approved plans and construction authorization, and arrange inspections before covering the work. Keep the occupational credential separate from the site approval.
- Track the applicable renewal requirements. Renew installer certification annually with the required application, insurance, fee, and applicable education documentation. Confirm the current continuing-education schedule with MSDH rather than borrowing requirements from the evaluator or pumper program.
