I can't help you with any info, but what is the water quality like in that area and how do you get water now? Are there any ongoing taxes or consumption fees payable?

Paid $3700. two years ago in Northern Maine. That included 20' steel casing the pump, a 75' x 1" poly and electrics run to the house, the pressure tank and switch. The well depth is 180 feet and produces 15 gpm. I installed a dual pole 20 amp circuit and connected the switch to the panel myself. The excavation from the head to the foundation was an additional $400.

So does the quote seem high? The well depth would be almost double of yours (330 feet).

Water is decent, comes from an aquifer that is fairly clean and plentiful. I don't live there right now, it's just land that I own. There is a $300 fee for a well permit, after that, there are no other fees and it is outside of the regulated area so you can pump up to 35GPM without impediment.

Your lucky Pettrix because in Australia most Aquifers
have been purchased by the Coke Cola company from the government or if they have not we have to pay a yearly licence to draw metered water.

Pettrix, I think your price estimate is okay. What I didn't see directly quoted was the pressure pipe from the pump to the pressure tank and also the 350' of copper wire downhole to the pump. Will your driller use schedule 80 PVC pipe or galvanized pipe? I have PVC and love it.

Just to be on the safe side, you might get another quote, but it's important to find a well driller who has been in business for many years and is familiar with your area. I have a neighbor who hired a cheap driller and ended up with a stuck drill pipe and bit down at 285'. The driller tried to convince him that there was sufficient water at that depth, but he listened to me and several other neighbors that the well needed to be around 400'. He had to fire his original driller and get a driller who would put him in a proper well. I don't think you can go wrong by checking with neighbors for their experiences. They can tell you the best well depth and make suggestions for drillers.

That said, I don't see anything wrong with your numbers. In fact, I think that well would cost a bit more if it were drilled here in Texas.

I have had two wells drilled, one in 1980 and the other in 1999. Basic cost on the last one was $20.00 per foot, plus extra for pump and parts. To me, given the price up here, your price seems reasonable. I'm sure prices do vary somewhat from area to area. Main thing is you end up with lots of good water. :licking:

My well was drilled in May 2005--154 ft deep, drilling 160 ft steel casing 6-5/8" x .134 wall ($3360, $21/ft), 20ft annular well seal ($450), (1) 6-5/8" steel drive shoe ($85), permit($191.25), 1-1/2hp pump,pipes, 86 gal pressure tank($1800). Total: $5886.25

The well completion report says the estimated yield is 100+ gal/min. With the 1.5 hp pump it's about 30 gal/min. Depth of static water level is 53 ft. The pump is located about 120 ft deep and is at the 3rd strata. The bottom of the well is in the 4th strata.

Excellent Mt. Shasta water:thumbsup:.

The drilling costs are inline with what is going on around here. If you are a little handy, could save a bunch of money on the pump, tank, ect by doing it yourself. You will need a couple of people to help lower the pump, spacers, and wire, as well as the safety rope down the well, but I bought my last pump from Granger. Submersible Well Pumps - Well Pumps - Grainger Industrial Supply And they have the spacers as well. Go for a "3 wire pump" but you will need a extra box with one for the capacitor. Adds about 100 bucks, but the pump will last longer. Our main pump, 2 houses, is over 25 years old now, but have replaced the capacitor about 4 times over the years( less than 10 bucks each time)
