Filtering water from deep well (700 feet)

[econometrics]

We recently had a deep well drilled here in East Texas for our new home. It's drilled 700 feet deep and I think the pump is hung around 580'? I could be wrong there, I don't remember.

My well guy says I don't need to filter any of the water for sediment or contaminants, but he's also a classic East Texas "good ole' boy", ha!

The biggest concern I have when considering filtration is water flow. Our pump will do 15gpm feed from a 1.25" line into our 1" line at the house.

I have looked at the Aquasana Rhino system, as it seems to have all the parts I've been thinking we would need:

- Sediment filtration
- Contaminant filtration (carbon and copper-zinc filters)
- UV filtration

I've tasted the water and it's VERY good and clean. I'm waiting to get back the testing report from the well driller to see the report.

What do any of you use out there to filter a deep well, while still keeping good flow?

Thanks

Years ago we had a deep well combined with a filter system. The well water went through the filter system, then into 1000 gallon holding tank. We used a jet pump pulling from the holding tank to supply the farm, always had great pressure and the large tank allowed for filter system time to recover the tank level.

Until you get the testing report back and have analyzed it - its difficult to advise what if any filtration may be required. One would certainly hope that there is no bacterial contamination from a 700 foot well. To automatically conclude that filtration is required is an error. Review the report with a qualified person from the company where the test was preformed. They should give you an honest evaluation.

Thanks. My well guy is pretty adamant that I don't need to filter ANYTHING after he saw the report. I haven't seen it yet, but should have it in the next day or two. He has been drilling wells for a long time, so he would know from one look at the report.

I'm not as much concerned with contaminants, as we will use a 3-gallon water filter for drinking water and cooking. I'm mostly concerned with sediment.

I use 5 micron string-wound filters for iron sediment. It is a simple in-out water flow. I change the filter about every 3 months. The whole filter unit costs around $40, the replacement elements run about $4-$6 each.

I don't notice any problem with flow which I think depends more on the pump than the depth of the well--assuming you have the correct pump for the well depth, adding a simple filter won't change much.

Thanks, Dave. Those are the only filters on your system? I realize I need to tailer my filtration to my well water report, but I'm just trying to get a feel for what others are doing out there, as searching the internets provides one with an overwhelming amount of noise from the pro and con camps of well filtration!

We where in Erath county Texas and used filters for primarily sand, the softer down the line took care of the calcium. We had far less sand after a year or 2 though.

My neighbor purify's water for a living. Did it for the Air force and now for Bell Helicopter. If you get your results and have a specific question, I will sure ask him for his thoughts if your interested.

That's good to know! If I can recall correctly, our driller said they hit sand right before they hit water... which is why I am concerned about getting some sand in the beginning of using the well. I guess we will see!

That's the only filter. The rest of the minerals in the well test are below filtration needs but we have plenty of iron, both sediment and dissolved types. The filter cartridge will be as orange as a new Kubota in 3-4 months. :laughing:

I would use a filter. Any sand or debris in your water will eat up a valve in your house over time and leave sediment in the water heater.

Wow! I know what you mean, as we have another well that is 250' and very iron-y. It stains everything orange!

Thanks for sharing your experience!

The proof is in the plumbing - maybe - sort of?
Check the screens on your faucets/shower heads and see if there's any grit trapped in them.
May be scale from the water heater or sand from the well

Filtration is important even if test show it's not needed I would want at least a sediment filter and retest every few years.

What size expansion and treatment (kill) tanks did you put in?

I soften for but do not filter mine.. I dont have 'hard' water per say, but do have iron and iron bacteria (leaves the rust stains if not ran through the softener)

But, if the test comes back good, I would think the most you would need to do is a standard string-wound 'sediment' filter. No need to UV bugs that arent there Instead of using one large filter, I would split the line into 2 parallel ones and one use 2. You can run 2 of the standard 12gpm slightly smaller ones together, or better, 2 24gpm ones that are more than your flow rate and alternate. That way you can bypass one while changing filters and not have to shut off the water.



Heres a 4 filter system with 3 in parallel..

As I posted, I use a 2 tank water softener system that does a real good job of getting rid of the orange.. They have dedicated 'green sand' filters for iron too, though these guys claim to do iron and more for less money and no maitenance..

Get the water tested before investing in an expensive filtration system. YOu should be able to get a kit from your local health department. Cost won't be much. Water from that deep should be pretty well containment free.

I haven't put anything like that in. My well guy basically told me that I could hook it right up to my home connection and let 'er buck!

Right now all I have in place is the well, pressure tank and mainline down to the house.

Thanks! This was the basic set up that I have had in mind - a parallel system for the sediment filters.

I would recommending the Big Blue canister with 10" x 4" filters.. I had the smaller filters and IF you have issues they clog up faster

I found that H2o Splash is a great place for housings and filters. I am currently using the 'washable' filters they sell.

Thanks for the tips. I collect such info like a squirrel collects nuts. :laughing:

I would say my filter is marginal for the amount of iron we have. No staining on fixtures or clothes, but definite orange coating in the toilet tank where it has a chance to settle out. So, I know some is getting through.

A while back, another poster recommended these too: Water purification, replacement filter cartridge, iron removal system, Fleck control valve
