Sewer Line Repair in Hillsborough, NH
In Hillsborough the sewer lateral — the run from the house to the public main — belongs to whoever owns the property, not to the utility. There are 2,916 occupied homes here, and across all the housing the median build year is 1977 — the best single clue to what the pipe is made of and how it tends to fail.
In short
Orangeburg cannot be ruled out by date in Hillsborough, where housing typically dates from 1977 and the plumbing code still permitted bituminized fiber. What settles it is whether the pipe still holds a round section.

What went in the ground around 1977
A lateral laid in Hillsborough in that period is most likely the tail of Orangeburg and the first plastic. The plumbing code still permitted bituminized fiber well into this period, so its presence cannot be ruled out by date. More on Orangeburg pipe.
What a camera survey should settle here
The code still permitted bituminized fiber this late, so its absence has to be confirmed on camera rather than assumed from the date. The full picture on Orangeburg pipe.
Hillsborough is the 40th largest block of laterals we cover in New Hampshire, carrying about 0.7% of the 436,947 homes on our NH list, and its housing runs older than 69% of the NH towns we route. Age concentration matters on a lateral: where a whole street went in one season, the failures arrive in one season too.
90% of homes here are owner-occupied — 18 points above the NH figure. That matters more on a lateral than on almost any other pipe in the house: the run from the building to the main is the property owner’s to repair, and a landlord and a resident owner do not find that out at the same speed.
Median household income across Hillsborough ZIP codes is $93,886 — which matters because a lateral is one of the few repairs with nobody else to send the invoice to.

Before anyone digs in Hillsborough, get the run on camera — and ask whether any bituminized fiber is present, because the code still allowed it here. What the recording should show you.
