Two questions decide most septic inspections in this city. If the property is on Webster Lake, state law is already in the deal — RSA 485-A:39 requires a septic site assessment before a developed waterfront property in the protected shoreland changes hands. If it’s anywhere else in Franklin, the question is whether the house is on the sewer or merely on a street that has one. Those are not the same sentence. The difference has landed on buyers after closing more than once.
Start with the lake, because that’s where the law has an opinion. Webster Lake sits at the north end of the city, six hundred and six acres, thirty-nine feet at its deepest, with a city beach on either side of it. The housing around it is a genuine mix — original camps, camps that got winterized in stages, and full year-round houses, sometimes all three on the same road. That mix is exactly what makes an inspection there worth doing carefully. A camp built for July weekends and a small tank becomes a year-round residence with a dishwasher, a washing machine and four people showering daily, and nobody consults the system in the ground about the change.
The shoreland requirement is a separate item from a home inspection and it catches people every year. It’s a site assessment, performed by a permitted evaluator, and it’s tied to the transfer rather than to your lender’s checklist. Put it on the calendar the day the offer is accepted. The version of this that goes badly is the one where somebody discovers it with a week to closing, in a season when everybody around the lakes is trying to book the same handful of people.
Off the water, the trap is the records. “Sewer available” means the main runs past the property. “Connected” means somebody paid to tie in and there’s an account. About two-thirds of city streets have sewer available, which means a listing sheet saying “public sewer” is right often enough that nobody questions it — and wrong often enough to hurt. We have opened live, working tanks in the yards of houses everyone in the transaction believed were on the city system. There are also properties that connected decades ago and left the old tank in the ground, sometimes properly abandoned and sometimes not, which is a hole in your yard that you now own. Get the connection record from the city. Not the MLS sheet, not the seller’s recollection, the record.
The other thing worth naming about buying here: Franklin is one of the last reasonably affordable ways into the Lakes Region, which means the buyer pool skews toward first-timers and small investors, and the housing they’re buying is old. That combination raises the stakes on this particular inspection. A field replacement discovered in year one is survivable when there’s cushion in the budget. Around here there very often isn’t, and a few hundred dollars up front is how you find out before it’s yours.
Ask for the septic paperwork in writing during the inspection period — the state approval, the as-built plan, and every pumping receipt the seller can lay hands on. It costs nothing, it’s the one moment in the life of the property when someone is motivated to go find it, and it tells you the tank’s size, its location and its permitted bedroom count in about ninety seconds. Owners who inherit that folder tend to keep the system fifteen years longer than owners who start with nothing.
We pump the tank as part of the inspection. You cannot evaluate a tank whose bottom you can’t see — an inspection that skips the pump-out is a long look at a full tank followed by an educated guess. Empty, we read the walls and the seam, both baffles, the condition of the concrete or the steel, and whether the tank has been holding its liquid level or quietly losing it into the ground. On a purchase the pump-out isn’t money spent twice either, since it’s maintenance the property needed anyway.
Then the field. We locate and open the distribution box, look at whether flow is being shared across the trenches or one line is carrying the entire house, and check for the signs that a field is finished: effluent at grade, ground that gives underfoot, standing liquid in the d-box with the tank already emptied, that unmistakable stripe of dark green grass in the middle of an August lawn. We also run water inside the house and watch what happens under load, because plenty of systems look fine at rest and quit the moment a real household turns up.
You get a written report with photographs, a plain-language condition assessment of the tank, the field and the line, an estimate of remaining service life where we can honestly give one, and the specific items we’d want addressed and roughly what they cost. We also write down what we could not determine and why — a buried component we couldn’t reach, a field whose layout isn’t documented anywhere. Guessing on paper for a buyer is worse than admitting the gap.
What we do not do is tell you what you want to hear because there’s a closing date. We have written reports that killed deals. We’ve also written reports that gave a buyer the number they needed to negotiate the price down and buy the house anyway, which is the more common outcome by a wide margin. Either way the report says what we found.
A full inspection including the pump-out runs $450–$700 with a written report, depending on tank size and how buried things are. A shoreland site assessment under RSA 485-A:39 for a Webster Lake property is a separate item and gets quoted per property. Give us the address when you call and we’ll give you the real number for that place rather than a range.
Spend ten minutes confirming it before you decide. Ask the city’s sewer division whether there’s an active account at that address, not merely whether the main runs down the street — those are different records and only one of them answers your question. If there’s no account, there’s a tank out there somewhere and you want it opened before you own it. If there is an account, ask whether an old tank was left in the ground when the house tied in, because an unabandoned tank is its own problem.
Generally not in any way you should rely on. Most home inspectors will flush a toilet, look for wet spots and write a line recommending further evaluation by a septic professional. That’s an appropriate thing for them to write and it isn’t an evaluation. Nobody is opening the tank, nobody is opening the d-box, and nobody is loading the system. On a Franklin property where the tank may predate the war, that line in the report is where your due diligence starts, not where it ends.
The day the offer is accepted. Site assessments require a permitted evaluator, there are a limited number of them working the Lakes Region, and spring through fall is when every waterfront transaction in three counties wants the same weeks. Booking it early costs you nothing if the deal falls apart. Booking it late is how closings get pushed. Tell us it’s waterfront when you first call and we’ll get it moving in the right order.
A recent pump-out is a good sign and no more than that. It means the tank was emptied. It doesn’t tell you whether the tank holds liquid, whether the baffles are still attached, or whether the field accepts water — and a tank pumped shortly before a showing is also the oldest way to make a struggling system look calm for a few weeks. Ask for the invoice, absolutely. Then have it looked at anyway.
What the system was approved for, and when. A tank sized for seasonal weekend use is a different machine from one carrying a full-time household, and the gap between them shows up as a failed field about three winters in. Get the original approval if it exists, get the bedroom count that approval was based on, and have us evaluate the system against how you actually intend to live there rather than against how the last owner used it. Better to price that in now than to find it after you’ve moved.
