South Dakota Septic Contractor License Requirements (2026)
By Gabriel Giner, Editor · Source checked 2026-09-30
South Dakota’s current installer licensing route runs through the Plumbing Commission. DANR’s septic guidance directs installers to that program. The Commission identifies an Individual and Small On-Site Wastewater System Installer credential and publishes a February 2026 application. Do not substitute the different experience requirements for sewer-and-water contractors or rely on an older DANR-only application process.
Regulatory Body
South Dakota Plumbing Commission / DANR administers and enforces this credential. Use the cited agency guidance for the named installer pathway and the authority responsible for each project.
Eligibility Requirements
This guide does not establish a minimum applicant age; confirm any age requirement with the issuing authority. Applicants must provide a Social Security Number. 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
Submit the current onsite wastewater installer application and $50 application fee to the Plumbing Commission. Complete the identity, business, and disclosure fields. The application warns that it expires 45 days after receipt if the process is not completed as required.
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: South Dakota Plumbing Commission / DANR. 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 Unpublished format details do not remove an examination requirement:
- Individual and Small On-Site Wastewater System Installer examination — question count: confirm with the authority, timing: confirm with the authority, passing score: confirm in the current candidate bulletin
Examination fee: $100
The Commission administers installer examinations and lists a $100 installer examination/reexamination fee. Obtain application approval and pay the examination fee before scheduling.
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
Confirm the current insurance documentation and coverage required for the actual credential, employer, and locality. No unverified coverage minimum is quoted here.
Workers' compensation
Confirm employee coverage obligations separately; the septic program sources do not establish a workers’ compensation exemption.
Fee Schedule
$50 application plus the Commission’s $100 installer examination charge. Initial license issuance and renewal charges are not established here; confirm the amounts requested after approval.
| Fee | Amount |
|---|---|
| Application | $50 |

Renewal and Continuing Education
Use the renewal instructions for the onsite wastewater installer credential and the expiration on the license. The Commission’s 2026 specialty-renewal notice does not by itself establish one renewal charge for every listed occupation.
Continuing education: Confirm the education requirements for the actual credential or local authorization. No unverified number of continuing-education hours is quoted here.

Out-of-state credentials must be considered under the septic program’s own rules. The pathways documented below do not establish NASCLA examination credit.
| Reciprocal State | Accepted Exam | Conditions |

| No formal bilateral reciprocity agreements identified. | ||
Do not assume an outside installer credential transfers automatically. Ask the issuing authority to evaluate it under the named pathway; any credit or exemption must be confirmed before relying on it.

Step-by-Step Application Roadmap
- Identify the applicable installer pathway. The one-year and two-year experience statements under sewer-and-water licensing are for those named occupations, not automatically the septic installer application.
- Prepare the qualification records. Submit the current onsite wastewater installer application and $50 application fee to the Plumbing Commission. Complete the identity, business, and disclosure fields. The application warns that it expires 45 days after receipt if the process is not completed as required.
- Complete the applicable assessment and filing. The Commission administers installer examinations and lists a $100 installer examination/reexamination fee. Obtain application approval and pay the examination fee before scheduling.
- 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. Use the renewal instructions for the onsite wastewater installer credential and the expiration on the license. The Commission’s 2026 specialty-renewal notice does not by itself establish one renewal charge for every listed occupation.
