Cost for Septic System and Well
Because I have one 340 feet deep. I'm sure costs have gone up though. But 30k?
I got a quote for a well and cistern (3k gallon) last year. Quoted $60/ft to drill (we're also in a very rocky area), plus materials/plumbing/equipment and hookup. Well control and booster pump was quoted at $6k, almost $14k for the cistern and it's controls and pump. My current well depth is near 300ft (cased 30ft to solid granite), which would cost $18k to drill today, plus cost of the casing. Due to new local rules, the cistern is more or less required (fire department wants you to have water available if no hydrant at the property, and will deny the well permit w/o the cistern being on the plan).
Oh, and well drillers are booked out 16-24 months around these parts which makes it impossible to negotiate costs - and they're likely to go up between deposit and execution. Which is why I decided against moving forward.
No idea on septic, but I had a drain field issue from people not listening about what goes down the drain, and at that time I was given a verbal ballpark of $15-25k to install a new field assuming there was space/room for it (no one will take the soiled soil from around a drain field and so putting a new one where the old one is would be a no-go). That doesn't include a new tank, plumbing it, etc. But I figure new work is often cheaper, and the tank is likely $4-8k depending on size. So $20-30k for a tank and drain field feels about right.
