Septic in Rehoboth is governed by Title 5 (310 CMR 15.00). The Rehoboth Board of Health issues the disposal works construction permit, and a witnessed deep-hole and percolation test must establish soil and groundwater conditions before design. A registered sanitarian or professional engineer stamps the plan, and a licensed installer builds it. Because nearly every lot has a private well, setback distances get close scrutiny, and parcels near streams or wetlands may need Conservation Commission review under the Wetlands Protection Act. A Title 5 inspection is required before most property transfers.

Septic costs in Rehoboth sit at southeastern-Massachusetts rates, below Cape and Boston-metro pricing but lifted by the town's heavy soils. A conventional gravity replacement typically runs roughly $20,000–$30,000, but slow-percolating clay often forces a larger, pressure-dosed, or mounded system at $30,000 or more. A Title 5 inspection runs a few hundred to about $1,000, perc and soil testing a few hundred to over a thousand, and tank pumping a few hundred. Slow-draining soil is the main cost driver here, since poor perc rates push designs toward the expensive end.

Massachusetts requires a written contract and a Home Improvement Contractor registration for most residential septic installation & service work; ask for the registration number and check it before paying a deposit.
