Septic, Sewer and Excavation Services in South Kingstown

About 60 percent of South Kingstown residents rely on a septic system, by the town's own count. Public sewers reach only about a tenth of the land, and private wells serve about 80 percent of it. Near the coast, that ground drains to the salt ponds, where the state's septic rules are stricter. The town also runs its own septic inspection program, with deadlines for failed systems and cesspools.

South County Septic and Excavation Services designs and installs septic systems, and South Kingstown is part of our service area. We handle septic system installation in South Kingstown for new homes and for replacement systems. Each septic system design goes to the Rhode Island Department of Environmental Management (RIDEM) for approval before the dig starts. Call or text (401) 474-8926 to talk through a South Kingstown lot.

Is your South Kingstown home on sewer or septic?

The town sewer serves Wakefield, Peace Dale, Kingston and Middlebridge. The University of Rhode Island runs its own system for university property. Both feed a regional treatment plant in Narragansett. Together they cover about 40 percent of the town's homes, the town's community plan says.

The same plan says outlying villages should not be considered for sewer service, except Middlebridge. That leaves Matunuck, Snug Harbor, East Matunuck and Green Hill on septic, along with West Kingston and Perryville. In the rural zones, the plan discourages public sewers. One zone allows about one home per five acres, to protect groundwater and coastal pond watersheds.

For a typical house, RIDEM's rules start with 100 feet between the leach field and a private drinking water well. A home that ties into town sewer starts with an approval letter from the town's Wastewater Division. We also do sewer line installation for homes that tie in. The town wants its sewer inspection booked at least 48 hours before digging.

Nitrogen-reducing systems around the salt ponds and the Narrow River

RIDEM's rules set a Salt Pond Critical Resource Area over the land that drains to the salt ponds. All five South Kingstown coastal ponds are on its list: Point Judith, Potter, Cards, Trustom and Green Hill. A matching Narrow River Critical Resource Area covers land that drains to the Narrow River near Middlebridge. The Coastal Resources Management Council (CRMC) maps both, and a septic plan shows the line if it crosses the lot.

Inside both areas, RIDEM requires nitrogen-reducing technology for every new home. The same rule covers alterations and repairs, with a narrow waiver for some tank-only repairs. The system must cut total nitrogen at least in half and discharge no more than 19 milligrams per liter. The town requires more frequent maintenance for innovative and alternative systems like these.

The same rules limit where a leach field can go. It cannot sit where the seasonal high water table comes within five feet of the surface. At two to five feet down, the rules allow an approved alternative technology or a shallow trench layout. In the faster-draining soils, the stone under the field must sit at least four feet above that water table.

South Kingstown's septic inspections and cesspool deadlines

The town's onsite wastewater ordinance requires septic inspections in prioritized districts. Inspections generally come every two to five years, based on the system's condition. After a town notice, the owner has 45 days to get the inspection done. A licensed inspector from the town's list does it and files the report with the town.

Census estimates put about four in ten South Kingstown homes before 1970, with a median year built of 1978. The year 1970 also matters under the town program. For a cesspool or a system installed before 1970, the town requires a pump-out at the inspection. For a newer system, the town recommends one.

When an inspection finds a failed system, the town issues a Notice of Violation. The owner then has 18 months to repair it or replace it with a new system the state approves. A broken pipe or a failed leach field may be a job for septic system repair. Cesspools must be replaced by the earlier of 12 months after a sale or five years after the first inspection.

How do soils and wetlands shape a South Kingstown septic system?

Federal soil maps from the Natural Resources Conservation Service (NRCS) show Bridgehampton as the most common soil in town. It is silty, and NRCS says its lower part is often saturated in winter and spring. Hinckley sand and gravel, also common here, drains fast. The town's community plan finds septic limits on almost half of its unsewered residential land zoned under two acres.

Wetlands cover about 29 percent of the town's land, including the Great Swamp. The town's plan flags parts of Card's Pond Road and Worden's Pond Road for flooding from saturated ground. A septic system within 150 feet of a fresh or salt water wetland needs a town special use permit. That rule comes from the town's checklist for a new house, and the Zoning Board of Review hears the request.

The town's Building and Zoning Department issues the building permit for a new house. The application needs RIDEM's septic permit in the owner's name and a Class 1 survey that marks the septic system. Digging for a new house may also need a soil erosion permit from the Public Services Department. Erosion controls are part of our site work, and the town inspects them before it issues the building permit.

South County Septic did an excellent job replacing our old septic system and leach-field. Michael surveyed the property, designed a new system, installed and worked with the RI DEM with no issues. I highly recommend this business.

Conner Marleya year ago · Google review

Michael was great! Picked up right away and was able to come within the hour to evaluate. Immediately got into motion additional resources we might need to come that day and solved the problem. Very informative and great to work with. Highly recommend.

Andrea McGregora year ago · Google review

Was referred out to Michael after an emergency waterline break that flooded our basement. He was there every step of the way and answered all the questions we had. Michael let us know what was happening during the process and could not have been happier with the outcome. Great price and great customer service! Highly recommend if anyone is in need of their services

Samantha Bomzera year ago · Google review

Michael was excellent. He replaced a main water mine to my rental property. Prompt, on time and does great work. I am someone who is extremely picky when hiring contractors for anything. He checked a lot of boxes when we first met answering questions and demonstrating his knowledge. Highly recommend!

South Kingstown FAQ

Questions We Hear Around South Kingstown

A few of the questions we hear most around South Kingstown. If yours is not here, call or text and ask.

Call (401) 474-8926

What happens after a South Kingstown septic inspection?
The inspector gives you the report, and the town sends a reminder before the next one is due. If the tank needs pumping, the pumping receipt goes to the town within 30 days of notice. A system that needs repair draws a Notice of Violation, with 18 months to repair or replace it.
What happens to a cesspool when a South Kingstown house is sold?
The town requires the cesspool to be replaced within 12 months of the sale. State law sets the same 12-month window after a sale or transfer. RIDEM notes that the law does not say whether the buyer or the seller is responsible. When the work is done, the town wants a copy of RIDEM's Certificate of Conformance.
What does septic system installation in South Kingstown cost?
Inside the salt pond area, the price covers a required nitrogen-reducing system, which also needs regular service. Test holes show the soil and the water table, and a wet site may need fill or an alternative design. The town's Community Septic System Loan Program can help with a repair or a cesspool replacement. We look at the job and put the quote in writing.
Where can I find the records for my South Kingstown septic system?
The town points owners to RIDEM's online septic permit search, which holds records from 1968 to the present. For a house built after 2016, the Building and Zoning office may also have the records on file. If the town program has inspected the system, the inspector's report is another source.
Who approves a septic system in South Kingstown?
RIDEM reviews and approves the septic design before any work starts. The town's Building and Zoning Department issues the building permit once the state approval is in hand. Building within 200 feet of a coastal feature also needs a CRMC assent. Before move-in, the town asks for RIDEM's Certificate of Conformance.
