Key takeaway
In Holliston, Eversource brings in both electricity and natural gas, and the town's Water Department supplies drinking water. Most homes don't have town sewer at all; they're on private septic systems overseen by the Board of Health. Trash and recycling go out in town-issued carts and are picked up weekly by E.L. Harvey. Your electricity supply can come from Eversource basic service, the Holliston Community Choice program or a supplier you pick.
Who this is for: people moving to Holliston, buyers getting ready to close, and anyone who wants to know which company to call for what.
Setting up a house in Holliston is a little different from a lot of towns around it. The utility list is short, but septic instead of sewer and the town cart program surprise plenty of new residents. Here's who handles each service and what's worth knowing before your first bills show up.

Electricity in Holliston
Every home in Holliston is in Eversource's electric territory. Eversource owns the poles, wires and meters, restores power after storms and sends the bill. That bill has two main parts: delivery, which always goes to Eversource, and supply, which is the electricity itself.
If you've never chosen a supplier, you're on Eversource basic service or the town program. Eversource's residential basic service rate is 17.32 cents per kWh (as of November 2026), a rate set for August 1, 2026 through January 31, 2027. It resets every February and August.
Holliston Community Choice Power Supply Program
Holliston has run its own electricity aggregation since January 2016. The town picks a supplier through a competitive bid on behalf of residents, and Eversource keeps delivering the power and sending the bill. Eligible accounts on basic service get enrolled automatically unless they opt out, and the program has no enrollment or exit fees. The program's rates and its supplier change with each new contract, so check the Supplier Services section of your bill to see what you're on. Colonial Power Group runs the program for the town and takes opt-in and opt-out requests at 866-485-5858, ext. 1.
Keep in mind that a town program or a supplier switch only changes the supply side. Delivery charges stay the same either way.
Natural Gas in Holliston
Eversource also handles natural gas in Holliston, but gas mains don't reach every neighborhood. Lots of homes in town heat with oil or propane, and some have switched to heat pumps. If you're buying, ask the seller what the house heats with and how old the system is. If you ever smell gas, leave the house first and call 911 from outside.
Water and Septic in Holliston
The Holliston Water Department, part of the Department of Public Works, supplies town water and sends the water bill. Holliston has put outdoor watering bans in place in dry seasons, including 2026, so check the Water Department page before you start watering a new lawn.
Sewer is where Holliston stands out. There's no town-wide sewer system, so most homes treat wastewater with their own septic system. The Board of Health, at Town Hall, handles septic permits and Title 5 rules, and a Title 5 inspection is part of most home sales. The town formed a Sewer Commission in 2024 and is working on a sewer district for downtown businesses, backed by state and federal grants, but that project isn't aimed at most neighborhoods. Plan on regular septic pumping as part of owning a home here.
Trash and Recycling in Holliston
E.L. Harvey picks up trash and recycling each week under a town contract. Trash goes in a town-issued 35-gallon cart and recycling in a 65-gallon cart, both out at the curb by 6:30 a.m. on your collection day. Extra trash needs town trash stickers, sold at Town Hall and a few local stores. For bulky items or a missed pickup, call E.L. Harvey at 800-321-3002.
The Marshall Street Recycling Center is open to residents on Saturdays from 8 a.m. to 3 p.m. with a recycling sticker. It takes yard waste, cardboard, metal, electronics and more. Holliston also offers curbside food scrap collection through a partnership with Black Earth.
Setting Up Utilities When You Move to Holliston
- Electricity: open an account with Eversource in your name, effective your move-in date.
- Gas: if the house has gas, start service with Eversource too. If it runs on oil or propane, line up a delivery company.
- Water: contact the Holliston Water Department to put the account in your name and get a final reading for the seller.
- Septic: get a copy of the Title 5 inspection report and find out when the system was last pumped.
- Trash: make sure the town carts stay with the house and look up your pickup day.
Cutting Your Electric Bill in Holliston
Electricity is usually the bill people feel most here, and it's a real piece of the cost of living in Holliston. A good first move is a Mass Save home energy assessment, which points out where your house is losing energy and which rebates apply. After that, many homeowners look at solar panels for their Holliston home to produce their own power and lean less on Eversource's rate.
