Some homeowner policies will cover that for a fraction of those prices-at least in my state.Just throwing my info in here.
I have water supplied by CT Water Company; my sewer is town run; there is a flat charge for residential sewer service. I believe it is $400/year.
My water company provides (3) levels of insurance for
1) outside water feed from street to house $90/year
2) outside water and sewer $154/year
3) outside water and sewer and inside plumbing. $190/year
I have chosen plan (1) and the distance from the road to my house is about 25 feet ( i am the last house on a dead end, no turnaround street)
Distance of feed doesn't impact cost; it is simply a way of distributing risk with other homeowners; i'll take that.
Looking @ my water feed, i think it is probably leaded steel or galvanized; in 25 years living here, I've never called.
Good thing for the OP'r it was not February; maybe count your blessings.
