Filtering water from deep well (700 feet)

[farmer2009]

I see, thank you. But the idea is basically the same... the longer the lift, the higher the HP needed? My lift on the 700' well is 120 feet. My lift on the shallow well is 20 feet. I guess that's why I need a 3hp on the 700' well, and a 2hp will do on the 250 footer.

Makes since. I am lifting about 30 feet even though my water is on the surface. I am guessing that there is a point at which the pump starts to loose flow because of head pressures.

Yep, that's correct.

Yes. I should have continued and explained that the "lift" also has to include any elevation above the well head to where the tank is located. Tanks do not have to be anywhere near the well head.

This if you water is (at the surface) and the tank right there you come close to having a zero head lift.

That is the theorectical. Turbulance, restrictions in piping, friction all add to the pumping load.

Thanks. It's quite a bit of change and could get really expensive if it goes bad. In our area almost everyone uses the same guy. Probably very good since that many people have used him and everyone recommends him. IT sounds like his price is about the same as what you paid. I'm trying to get some other quotes, but both of the guys I've dealt with so far seem about the same.

I know that the neighbor is having to change his filter about every 3 weeks. Does anyone use sedimentation tanks? Some old wells around Pipe Creek have them and a friend that has one recommends one. They drain the tank regularly. I don't think they have the iron issues that we have around Seguin.

If you read this thread from page 1, you'll see quite a few people who use sediment traps. They are one of the most common features when filtering well water.

It really depends on the depth of the well and the test results from your water sample after the well has been drilled. Our water test came back showing a very minimal amount of particulate matter in the water so I don't think we will do any filtering at all.

I'll see how it goes the first few months of use, then decide if we need a sediment trap at all.

The trick to sediment tanks is to get one big enough for it to work. You want to be able to shower or do laundry while still having clean water. That is where the cost comes in although I don't know how big to recommend. As we use our system (pond) to water livestock and the flow is to great for sediment tanks to be cost effective as we need to a also add time for algae kill.
