Septic, Sewer and Excavation Services in East Greenwich

In East Greenwich, sewer or septic often comes down to which side of Route 2 your house sits on. The Rhode Island Department of Environmental Management (RIDEM) reports that the town sewer serves the area east of Route 2. That covers about two-thirds of the town's people, and the rest rely on onsite systems. West of Route 2, the ground is often stony glacial till with wet low spots.

South County Septic and Excavation Services handles septic system installation in East Greenwich, part of our service area. We start with septic system design for new homes and for replacements. RIDEM approves the plans, and then we install the system. Call or text (401) 474-8926, and we look at the job and put the quote in writing.

Which East Greenwich homes are on septic?

The town's Sewer Division runs 42 miles of sewer lines and the treatment plant on the harbor. The plant was first built in 1927, and today it removes nitrogen in two steps. The town's draft 2026 plan update says the plant needs a major upgrade to support more growth.

Land splits the other way: roughly two-thirds of the town lies west of Route 2. The plan calls that side rural, with limited water and sewer capacity. In its low density areas, the plan allows one home or less per two acres, with no public sewer. South Road and Tillinghast Road both run through this side of town.

Close to the sewer, the state rules point toward a connection. RIDEM will not approve a new septic system where the sewer is reasonably accessible and the town allows a connection. A new hookup falls under sewer line repair and installation, and so does a cracked or root-filled sewer lateral. We do that work in East Greenwich too.

Stony till and wet ground west of Route 2

USDA soil surveys map more than half the land west of Route 2 as stony soils over glacial till. Bridgehampton and Narragansett soils lead, and both drain well. About one acre in eight is wet, dense till, such as Ridgebury and Whitman soils. There the water table can reach the surface in the wet season.

The state's onsite wastewater treatment system (OWTS) Rules decide what fits on that ground. The stone under a leach field must sit at least 3 feet above the seasonal high water table. It must also sit at least 5 feet above a restrictive layer or bedrock. The rules describe lodgement till as dense and hard to dig, with a high chance of a restrictive lower layer.

If RIDEM and the soil evaluator agree the readings are unclear, the water table gets measured in the wet season. Those readings run from January 1 through April 1. When an older system in wet ground backs up, septic system repair begins with finding the cause.

Private wells and new homes on the west side

Most of East Greenwich gets public water from the Kent County Water Authority. Part of that supply comes from the Hunt River aquifer, which the draft plan aims to protect. The plan also says water service is harder to extend in the western parts of town. Where a lot or a neighbor uses a private well, the state rules add limits.

For a home system below 1,000 gallons a day, the leach field must stay 100 feet from a private well. The tank must stay 75 feet away, and the building sewer 50 feet. Near onsite wells, a new home needs about one sixth of an acre of lot per bedroom. A nitrogen-reducing system can allow more.

The draft plan proposes new zoning in the northwest quadrant to promote housing. On a new lot, the septic layout shapes where the house and the well can go. We clear and grade the lot around that plan as part of our site work.

Cesspools in East Greenwich and the sale deadline

Rhode Island's Cesspool Act starts a clock when a home with a cesspool is sold. Within 12 months of the sale, the cesspool must give way to an approved system or a sewer hookup. When a home may have a cesspool, the purchase contract gives the buyer 10 days to inspect the system. Both sides can agree on a different period.

RIDEM notes that most home systems installed after 1970 are not cesspools. Census estimates date about four in ten East Greenwich homes to before 1970. Cesspools within 200 feet of a tidal shoreline, such as Greenwich Cove, had a January 1, 2014 deadline. The town's draft 2026 plan update calls for abandoning all blackwater cesspools.

Replacing a cesspool means a new septic system, designed for the lot and approved by RIDEM. Our cesspool replacement work follows that path, from the test holes to RIDEM's Certificate of Conformance.

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!

East Greenwich FAQ

Questions We Hear Around East Greenwich

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

Call (401) 474-8926

How can I tell if my East Greenwich home is on sewer or septic?
If you pay a town sewer bill, your home is most likely on the town sewer. If not, it likely has a septic system or a cesspool. RIDEM keeps records of most septic systems from 1968 on, and you can search them online. The Sewer Division, part of the Department of Public Works, can answer the sewer side for your street.
Who approves a new septic system in East Greenwich?
RIDEM must approve the plans before a new septic system goes in, in East Greenwich or any Rhode Island town. The town's Building Department, part of Public Works, cannot issue the building permit until those state approvals are in hand. The town grants a certificate of occupancy only after RIDEM issues its Certificate of Conformance for the system.
What does septic system installation cost in East Greenwich?
In East Greenwich, cost turns on what the test holes find on your lot. West of Route 2, wet or dense till can change the system type and the leach field size. A private well nearby also shapes the layout under the setback rules. We look at the job and put the quote in writing.
Can I add a bedroom to a house on septic in East Greenwich?
The state rules weigh in first. A system approved for fewer bedrooms needs a new RIDEM application before the addition can go ahead. A cesspool, or a system installed before April 9, 1968, must be upgraded before most additions or a major renovation. The town Building Department handles the building permit for the addition itself.
Does East Greenwich have its own septic program?
A 2022 RIDEM summary says East Greenwich does not have an approved onsite wastewater management plan. The town's draft 2026 plan update proposes a wastewater management district ordinance. Under state law, a fund helps homeowners replace cesspools and inadequate septic systems in towns with such a district. The Planning Department can tell you where that proposal stands.
