Hi everyone,

I am in the process of having a borehole drilled, if all goes well it should be drilled in the next two to three weeks. The survey has already been done and all indications are that my property has water around 50m deep.

I have already installed a 5000 tank and Zilmet 1.1 VSD pump which should work well with my solar system.

I will definitely first have the water tested once the borehole is in but I would like to ask for some advise regarding the size of vessels needed and what type of media for the different contaminants, so that I know what media to buy when I get the report.

I would prefer staying away from Big Blue filter as I don't want to be buying new filters every 6 - 12 months. I would rather buy 3 vessel filters if possible.

I have spoken to Blue Spot and Puritech regarding a solution, Puritech advised that it is possible to only have a vessel solution and Blue Spot advised me that the smaller microns can only be filtered out by a Big Blue filter solution, so I am very unsure.

I am quite handy, and I will be able to do the installation myself, if I can only understand what media to use to filter out the different contaminants?

Any advise will be greatly appreciated.

Kind regards,

Oelof

My first advice would be to wait 4 to 6 weeks minimum before getting your water tested after having pumped for at least a few hours a day.

A lot will depend on your test

You could possibly get away from big Blues, but it will depend on the test and what you are wanting to use the water for

If you are wanting to use it in the house, how will you sterilize it?

If you are going to use a UV filter ( light), then it is recommended to have a 1 micron filter. So you would probably need at least one big blue

Most bead, sand, glass or resin filters only go to 5 microns at best

Hi Oelof

Going through this exercise myself, I agree with James 1 to wait before getting your water tested, and that you will need at least one big blue filter and other filters. I wasted a lot of filter material because my water ph had changed after some time. I would like to know what area you are from. I use mainly Clinobrite media, as it removes iron and other substances in a FRP vessel. It is better than sand or glass. You can read my posts and see what I have done to get acceptable drinking water under Sustainable Landscaping. It has been working well for about 8 years. The filtering depends on the test results showing the contaminants and the quantity of contamination.

Replacing media in an FRP vessel is not as easy as it is heavy because it is filled with water and media, and the opening is small.

Hi Peter and James,

Thank you for the informative reply.

I will irrigate the garden for about 6 weeks daily before getting the water tested. That should do the trick.

I think i will probably ask for advice again after the test results are back.
