Sewer Connection

If you have been advised that your property is included in an upcoming sewer expansion project, the following steps apply to you.

Sewer Connection Form

1. Complete Sewer Connection Form

Prior to construction beginning in the roadway, the Department of Public Works will contact you and ask you to fill out a Sewer Connection Form. This form allows you to provide details about your property, which will inform where your sewer service stub is located.

Connection costs will vary based on property characteristics. We recommend obtaining quotes from at least three qualified sewer installers.

Sewer Service Fee

The current typical residential sewer usage bill averages around $435 annually and may vary based on water usage.

Your Role in Septic to Sewer Conversion

The Town of Barnstable is responsible for the design, construction and operation of sewer mains, sewer pump stations, and sewer service stub pipes installed in front of each property, within the Town right-of-way. Property owners also have responsibilities in this process.

As a property owner you will be responsible for completing a pre-construction Sewer Connection Form. Upon project completion, property owners will then be responsible for hiring a licensed sewer installer to complete the connection from the stub left at their property line, within the public right-of-way, to building on their property.

Connection Timeline

The Town’s sewer construction will include installation of sewer force mains, gravity sewer, and sewer service laterals within the roadway. A sewer service stub will be installed within the Town right-of-way at your property line, which ultimately will serve your property.

As a property owner, your responsibility begins here. Once the Town has completed construction of sewers in front of your home or business, you will receive notification from the Board of Health, indicating that your property is now eligible to hook-up. The letter will specify the date by which you will need to connect the building on your property to the sewer service stub. On December 19, 2023, the Board of Health voted to ammend their Sewer Connection Policy, which now requires “the owner of a building on a parcel of land which abuts a public or private way in which there is a public sewer shall connect the building to the public sewer within six months of the Board’s letter notification.” Download the Board of Health Sewer Connection Policy, here.

At this point in time, property owners can also anticipate receiving communication from the Town Treasurer’s Office, regarding your Sewer Assessment charge.

How will implementation of the sewer expansion plan be paid for?

The estimated cost of the 30-year plan is approximately $1.4 billion, including construction, borrowing costs and inflation. The Town has already made significant progress in meeting this funding need. Through legislative action at both the state and local levels the town has created over 50% of the estimated funding sources needed for this program. For the remaining resources needed, the Town has developed an equitable and affordable financing plan to fully implement the CWMP.

The Town has created an existing dedicated revenue stream that will provide an estimated $600 million over the 30-year implementation timeline. This revenue stream consists primarily of proceeds from the hotel/motel room occupancy tax, short- term rental occupancy tax, local meals tax and a new excise tax of 2.75% that applies to all types of lodging on Cape Cod.

As new customers come on-line to the public sewer system, revenue generated from user rate revenue is estimated to contribute over $200 million to the plan.

How do the new Watershed Permit Regulations and revised Title 5 septic system regulations impact me?

The Town of Barnstable received the final Watershed Permit Regulations (314 CMR 21.00), and Title 5 Natural Resource Nitrogen Sensitive Area Regulations (“NSA”) (310 CMR 15.214 and 15.215), on Thursday, June 22, 2023. After completing a comprehensive review, our initial understanding is that the Town’s state-approved Comprehensive Wastewater Management Plan (CWMP) will comply with the requirements of a Watershed Management Plan (WMP) and can be used as the basis for a Watershed Permit.

Furthermore, as of September 1, 2023, the Town of Barnstable submitted its application for a WP95 Watershed Permit. Our application included the request for a Watershed Permit covering the entire Town of Barnstable, regardless of when, or if, a village was receiving sewer as part of our Comprehensive Wastewater Management Plan. Our application remains under review with MassDEP; we will be sure to keep our community updated throughout the review process.

Is my property located on a sewer expansion route?

If you are unsure if your property is located along a planned sewer expansion route, use the Property Look-Up Tool on the Town Assessor’s searchable database to find out if your property is located on a sewer expansion route proposed under Phase 1 of the CWMP.

Will I be contacted by the Town prior to sewer construction?

Yes, prior to construction beginning in the roadway, the Department of Public Works will perform a series of outreach efforts such as public information meetings, mailers and in-person door-to-door canvasing. Once your property has been identified as part of an active construction project, you will be asked you to fill out a Sewer Connection Form. The purpose of this form is to provide DPW with relevant information about how your current plumbing works. You will be asked to provide a sketch plan identifying your building’s layout in relation to the street as well as the preferred location of a sewer service stub connection on your property. Detailed instruction will be provided.

What costs am I responsible for when connecting to municipal sewer?

A property owner is responsible for essentially three primary costs. The first being a one-time Sewer Assessment, which is a charge that will be applied to the owners of properties that have one or more residential or commercial sewer units that are eligible to be newly connected to sewer service under the sewer expansion plan. Additionally, a property owner is responsible for the cost to connect their property to the municipal sewer system located in the street and to decommission the current on-site septic system, if needed. Connection costs will vary based on property characteristics. Lastly, once sewer service is connected, property owners will be charged a sewer service user fee based on their water usage. The current typical residential sewer usage bill averages around $435 annually and may vary based on water usage. If the property has irrigation, a property owner can install a deduct meter which will enable the property owner to realize a savings for water that does not enter the sanitary sewage system.

How do I find a qualified contractor to connect my property to sewer service?

You can find a qualified contractor from the Town of Barnstable’s list of licensed sewer installers, which is updated regularly and posted to the the Town’s website. Your licensed sewer installer will do the actual construction at your home on your property and will be responsible for applying for the necessary permits.

In most cases, a qualified sewer installer is sufficient for both design and implementation; however, in a limited number of cases it is necessary to also secure the services of a licensed engineer with civil engineering experience to direct your sewer connection. The connection must comply with the Town of Barnstable’s sewer connection design specifications. Your contractor will assist you in determining the most cost-effective way to arrange pipes on your property.

Do I have a choice whether or not to connect to new sewer service?

The Board of Health has the authority to require property owners to connect to the public system when it becomes live. The Board of Health also has the authority to allow property owners to delay connecting depending upon their unique circumstances. If you have a question or circumstance that you believe may necessitate a delay in connecting to sewer service, please call the Town of Barnstable Health Division at 508-862-4644 or email health@town.barnstable.ma.us.

Is there any payment assistance or abatement of either the Sewer Assessment or connection costs?

A property owner can opt to pay the Sewer Assessment all at once when due, or may opt to finance the Sewer Assessment and pay quarterly installments on their property tax bill over thirty years. In accordance with current policy, the Sewer Assessment under the thirty-year payback option would be amortized at an interest rate equivalent to 2% above the rate of borrowing, unless otherwise determined by the Town Council. If the sewer assessment is added to future tax bills, a lien will be recorded on the property at the Registry of Deeds.

The Town is also exploring the possibility of allowing qualifying homeowners the option to defer their sewer assessment if they meet certain income and asset limits. This would carry an interest charge and the sewer assessment would be paid at the time of a transfer in ownership or refinancing of the property.

Additional financial support includes zero and low-interest betterment loans through Barnstable County’s Cape Cod AquiFund and Cape Cod 5’s Sewer or Water Connection Loan Program. We will continue to update and share additional financial resources as they become available.

My septic failed and I am not yet connected to sewer, what do I do?

Like the decomissioning of your system, the Board of Health is the governing authority on all things septic. If you are currently living at a property with a failed septic system or in the process of buying or selling a property with a failed septic, the best first step is to determine where your property falls within the adapative sewer expansion plan. You can obtain this information by contacting Kelly Collopy, Communications Manager, for the Department of Public Works at 508-790-6400 or via email at Kelly.Collopy@town.barnstable.ma.us

Once you confirm anticipated sewer availability at your property, you will then need to contact the Board of Health to determine the most appropriate course of action. If your property is not eligible for sewer connection within an approved timeframe, the Board of Health may require you to make necessary upgrades or request replacement. If you believe your property’s septic may be failing, please call the Town of Barnstable Health Division at 508-862-4644 or email health@town.barnstable.ma.us.
