Rust from low producing well

[Greenmonster123]

Hi, I have a old well at my vacation cabin project that will produce cloudy rusty water. It is a 6” steel casing into rock, not sure how deep but the pump hangs at 100’. It has a high static level and sometimes even overflows the casing. It also is a low producing well which I have roughly figured to have a recharge rate of 3 Gpm. So what I think is happening is, when the a large amount of water is used it draws down the well quickly pulling rusty crud from the top of the casing. I haven’t used the well much as I am just getting things put together. In my mind I would think once things settel out and the water use is normal. Here is the issue in winter I will be draining the lines because the lateral is too shallow and will freeze so every time I start it up I will have rusty water. Are there any filters anyone can recommend for this issue? Thanks

Chunks of rust are easy to filter, rusty color not so much. Since it is a low producing well anyway, maybe the color will settle out in a storage tank?

The issue is the occasional use. If I had a tank I would still need to fill the tank upon arrival in the cold months and likely wouldn’t settle out in time for a quick weekend trip.

Not cheap, but a 4 inch PVC liner is possible in a 6 inch steel casing.

For cheaper, you could use a couple of Pentek Big Blue housings after the pressure tank. The first stage could even be washable.

A Patterson iron filter will remove fine rust particles. The problem with an iron filter is they are not suited to Winterizing so should be stored in a heated place.

How many GPM can the well produce and how many GPM do you need? Maybe a dole valve at the pump outlet to restrict the GPM? I wonder if a Lemco drawdown seal at the bottom of the casing would help?

I was thinking of a dole valve but have never used one. The well only makes about 3 gpm

The water gets rusty color when just sitting unused in steel casing an drop pipe. You might just have to pump it out for a while every time you show up and get some fresh water in the pipes.
