Direct answer

In most Massachusetts communities, the property owner pays to repair the private sewer lateral from the house to the public sewer, and the city or town pays for the public main. In Lowell, confirm who is responsible for the section under the sidewalk and street with the Lowell Regional Wastewater Utility before work starts [VERIFY AGAINST OFFICIAL SOURCE].

What to confirm before a repair

  • Where your lateral connects and which section is damaged (a camera inspection shows this)
  • Who is responsible for any section under the sidewalk or street
  • Permit and street-opening requirements, and whether a licensed drain layer is needed
  • Whether the backup is coming from the public main (call the utility if the house line is clear)
  • Whether your insurance policy has a service line endorsement

What a repair costs

In the Lowell area, sewer line repairs typically cost $1,066–$5,160, or $50–$250 per foot, and trenchless repairs $60–$250 per foot (market estimates). The camera inspection decides which method is possible.
