Connecticut has no county government, so septic permits come from town health districts and departments. Connecticut DPH says systems are regulated under Sections 19-13-B100a and 19-13-B103 of the Public Health Code, and sites with design flows of 10,000 gallons per day and less are permitted by the Local Director of Health.
Larger systems move up the chain: DPH says plans for buildings with design flows between 2,000 and 10,000 gallons per day must also be approved by the state. For a house, the district sanitarian is the person who approves soil tests, repairs and additions.
Fees vary by district. Two examples from current schedules: Chatham Health District lists a $185 septic permit for new systems and repairs, while the Quinnipiack Valley Health District lists $430 for a replacement permit with plan review.
Housing age explains a lot of the repair work. Census ACS 2017-2021 5-year data (Table B25034) count 76,287 housing units in Middlesex County, 62.8% of them built before 1980, and 368,720 in New Haven County, where 71.7% were built before 1980. Tanks and fields installed under older codes are reaching the end of their service life in both counties.
A few towns run their own health department instead of joining a district, but the process is the same either way: the sanitarian reviews soil test results, approves a repair design and inspects the open work.

Permits & Local Rules
- Step 1: Call the town health district or department; the Local Director of Health permits septic work under Section 19-13-B103.
- Step 2: Hire a licensed cleaner for pumping; Connecticut licenses cleaners and installers under General Statutes Chapter 393a.
- Step 3: For repairs, schedule soil testing and file the repair application; Chatham Health District's schedule lists $160 for one lot and QVHD's lists $255 for a replacement test.
- Step 4: The installer builds to the approved plan and the district inspects before backfill; additions on septic lots go through Section 19-13-B100a review first.
Soil & Site Conditions
- Ledge: much of Connecticut has bedrock close under glacial till, especially in the eastern and western uplands, so trench depth is often the limit.
- Sand and gravel: river valleys such as the Connecticut River valley near Portland have outwash sand that drains fast.
- Water table: shoreline lots near Long Island Sound often have groundwater near the surface, and spring rainfall raises it further.
- Older homes: a large share of housing was built before 1960, so older tanks and fields are common in town centers and inner suburbs.
- Frost: winter freezing makes late fall the easier time to pump.

Connecticut FAQs
Who issues septic permits in Connecticut?
The Local Director of Health in your town or health district, under Section 19-13-B103 of the Public Health Code, for systems up to 10,000 gallons per day.
How often should a Connecticut tank be pumped?
Connecticut DPH says on average every 3 to 5 years, by a licensed cleaner or installer.
Why do fees differ from town to town?
Each health district sets its own schedule. Chatham Health District lists a $185 septic permit and QVHD lists $430 for a replacement permit with plan review.
Is a county office involved?
No. Connecticut abolished county government, so health districts and town health departments handle septic permits.
What happens at a repair soil test?
The district sanitarian watches deep test pits and percolation tests, then uses the results to approve a repair design that fits the lot under Section 19-13-B103.
Can I add a bedroom without a new septic system?
Maybe. Section 19-13-B100a review checks whether the existing system and the reserve area can handle the addition; Chatham Health District's schedule lists $75 for that review.
