Get a Chatham Sewer Hookup Estimate

Chatham has been sewering for over a decade under its Comprehensive Wastewater Management Plan, with completed phases across the Oyster Pond and Stage Harbor watersheds and more neighborhoods being added to cut nitrogen in the town’s coastal embayments.

As sewer service reaches your street and the town notifies you to connect, tying in is how you retire an aging septic system and help protect Chatham’s waters. Shore Things Environmental handles the whole connection — design, permitting, excavation, and restoration — start to finish.

The advantage of working with Shore Things Environmental is that we know Chatham and we handle everything start to finish, so you’re not coordinating multiple contractors. Neighbors on the same road can even team up for group pricing — let us know if others near you are interested.

Chatham FAQs

Do I have to connect to the sewer in Chatham?

Once sewer is available to your property, the town generally requires connection within a set timeframe. We can confirm your street’s status and deadline.

What happens to my old septic system?

It must be properly abandoned under Massachusetts Title 5. We handle the abandonment permit and the work.

Can neighbors share costs?

Yes — homes on the same road often coordinate a group hookup for better pricing. Let us know if others near you are interested.

How Much Does It Cost to Connect to the Sewer System in Chatham?

The short answer: it depends. Every property is a little different, so costs can vary quite a bit. Things like how far your Chatham home’s plumbing is from the street connection, how deep the pipes are, and what’s underground (rocks, ledge, utilities, or even high groundwater) can all affect the final price.

As a Chatham homeowner, you’re responsible for the full cost of connecting your home to the sewer. The contract you sign with your engineer or contractor is private, so prices can vary depending on who you hire and what your property needs.

When planning your budget, keep in mind you’ll have a few required permits and professional services to pay for, including:

• Sewer Connection Permit: $0.50 per gallon of average daily water use, or $250 — whichever is greater

• Board of Health Septic System Abandonment Permit: Approximately $75

• Engineering (plans, specs, and permit applications): usually between $2,000 and $8,000

• Construction (connecting your house to the sewer, removing your old septic system, and restoring your yard or driveway): usually between $5,000 and $25,000
