Storage Tank Question.

I am new here,thanks in advance for any help.

I now own my Grandparents old property and am trying to improve water output. Here is what I have now.

Hand dug, 6 foot diameter, 60 foot deep well in high water table.
Water level 8 foot down from surface.
1 H/P submersible pump 45 foot down.
1 1/4 diameter pvc well pipe and surface piping to pressure tank.
Franklin Controller
86 gal pressure tank

Pvc run to house necks down to 1" to go to house and yard
House and yard 500 feet away and roughly 20-25 higher in elevation

When pressure is at 60 lbs at well, pressure at house is 40

I have just replaced piping at well from old metal pipe to pvc
new pressure switch
new check valve ( old one broke)

It is working fine, but I would like to be able to do more irrigation and have more supply to the house.

I have a 600 gallon storage tank that I am not using.

Thinking of putting near the house
pump from well directly into tank with water level switch
then buy shallow well jet pump and move pressure tank from well up by storage tank and have it provide distribution

My question, is this a good plan or is there a better way.

And what size jet pump. I want to be able to simulate city water pressure and flow.

Thanks

Robbie

I would not use an above ground storage tank for potable water. Depending on your terrain the tank could be placed on a high point, water pumped into it and gravity fed to do your irrigation. Having it near the house may not be aesthetically pleasing, nor will it provide pressure you are seeking. City/county water depends on gravity in most cases to pressurize the lines.

When laying your pipe, it is critical the direction in which you position the bells of the pipe. The bell must face the well in order to overcome turbulence at each joint, which will greatly reduce volume/pressure, plus your 25' rise isn't helping either.

The pipe has been in for years, so I am not sure about bell direction, but good to know for future.

The house is on the highest point. I don't mind the tank being seen. On 6 acres with plenty of trees, but are you saying not to use tank for house because of health reasons?

Is there another way? Larger pump? Higher pressure switch/tank?

Thanks for the help

I'm not sure what your tank is made of. Some materials will allow bacteria to grow since sunlight, heat, etc. are present. I found it particularly true in 300 gallon plastic caged water containment units. If there is a way to insulate it from the elements, then it may be ok. I would try increasing my pressure and possibly pressure tanks to see if you can obtain th pressure you want, PRIOR to delving further.
