Septic work in Hanson runs through the Hanson Board of Health under Title 5 (310 CMR 15.00). A licensed installer, an engineer- or sanitarian-stamped design, and a Board of Health disposal works permit are all required. A perc and soil evaluation drives the design, and the town's high seasonal water table in former bog and pond-side areas often forces a mounded or raised system. Work near the ponds, wetlands, or the Indian Head River also triggers Conservation Commission review under the Wetlands Protection Act.

Hanson septic costs sit near the statewide norm, with the water table the main driver of the spread. A full conventional system replacement commonly runs roughly $20,000–$35,000, while a mounded system in wet bog-area ground pushes higher, and a nitrogen-reducing I/A system runs $30,000 or more. A Title 5 inspection at sale typically runs a few hundred dollars up to about $1,000, and tank pumping is usually a few hundred. A seasonal high water table, not lot size, is the most common reason a Hanson job runs high.

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.
