Ninety-six properties in Moultonborough are hooked to sewer. Everyone else has a tank in the yard — and if the place only gets lived in for twelve weeks a year, the every-three-years rule doesn’t mean what you think it means.
The sewer here is one small district up by the Center Harbor line. The Bay District — about four miles of pipe following Lake Shore Drive and a stretch of Route 25, ninety-six homes and businesses on it total. That’s it. The other sixty square miles of Moultonborough sits on a tank, a field, and for most of the town a private well twenty feet from both.
So the interval question actually matters here, and the standard answer is a poor fit. NHDES says pump every two to three years, and for a house with the same four people in it every night of the year that’s sound advice. Moultonborough isn’t that town. The master plan counts roughly 1,800 year-round households against 3,699 second homes, and figures a second home holds about five people when it’s full. Add the camps and the campgrounds and the town works out to something near 24,800 people on a good August weekend, against about 4,300 in January.
Look at what that does to the one piece of infrastructure we can actually measure. The Bay District pushes 58,000 gallons a day through the winter. Come summer it runs 104,000. Same pipe, same ninety-six hookups, nearly double the flow. That’s the shape of the load in this town — a flat line with a mountain sitting in the middle of it — and your tank sees the same shape whether anybody’s metering it or not.
Which is why we’d rather you counted use than years. A camp that hosts nine people for two weeks in July and three long weekends after has done more work on that tank than a small year-round house does in eighteen months. Tell us how the place actually gets used and we’ll give you an interval that fits it. It’s usually longer than people fear and shorter than they’ve been going.
Nobody in this town gets a monthly sewer bill to remind them the system exists — ninety-six properties aside, there’s no bill to get. Write the pump-out date on the inside of an electrical panel door or the back of a cabinet at the camp. Sounds crude. It survives owners, caretakers and twenty years better than anything on a phone.
We find the covers and dig them up if they’re buried, which on a place that’s been seasonal for forty years they often are. Then the tank comes down, both compartments, all the way — not skimmed off the top so the truck fills fast and we can make the next stop. Skimming is why people who pump “every three years” still end up with solids in the field.
With it empty we look at what’s in front of us: the inlet and outlet baffles, the walls, the concrete at the waterline, whether the outlet has been passing material downstream. Ten minutes, and it’s the ten minutes that tells you whether you’ve got a maintenance item or a problem starting.
One Moultonborough-specific thing worth saying on the phone. Lots out on the Neck and around the bay tend to run long — road up top, house down toward the water, and the tank somewhere in between. If the truck can’t get within a couple hundred feet of the cover, that changes what we bring. Say so when you book and it’s a non-issue. Don’t, and we’re both standing in your driveway doing arithmetic.
Covers go back, the area gets tidied, and you get told what we saw. If nothing’s wrong we say nothing’s wrong and we leave.
A standard 1,000 to 1,250-gallon tank runs $300–$500. Buried covers that need digging, oversized tanks, long hose pulls on Neck and bay lots, or a tank that hasn’t been touched since the Clinton administration cost more — and you hear the number before the hose comes off the truck, not after.
Somewhere in the four-to-five year range for most seasonal Moultonborough properties, but that’s a starting point, not an answer. A camp that sleeps four and gets used quietly is different from one that sleeps twelve and hosts the whole family in July. Tell us the honest usage — number of people, number of weeks, whether there’s a disposal — and we’ll set a number you can put on the calendar.
Almost certainly not unless you’re near the Center Harbor town line, along Lake Shore Drive, or on the section of Route 25 the district covers. Ninety-six properties in the whole town are connected. If you’re unsure, look for a sewer line on your tax bill — and if there isn’t one, there’s a tank out there whether you’ve ever seen it or not.
Yes, and we do it constantly here — a lot of our Moultonborough work happens with the owner in another state. We need the tank findable, the gate code or the caretaker’s name, and permission in writing. We photograph what we find and send it along with the invoice so you’re not taking our word for anything.
Before. Going into a heavy stretch with a tank that’s already three-quarters full is how a fine system turns into a Saturday phone call. Spring is our busy run for exactly this reason, so booking in March or April gets you a date you actually want.
No. A working tank grows what it needs on its own, and nothing in a bottle turns solids into something a pump truck doesn’t have to remove. Some of it does real harm by loosening the sludge layer enough to push it into the field. Save the money toward the pump-out.
