Here is one for you guys to chew on.
I am developing a spring to supply water to some rental cabins. I have a new cabin built near the spring and the pump will be powered out of this cabin. Eventually I would like to supply up to an additional 3 cabins(4 total within 5 years). The cabins are small and will only accomodate couples(shower/toilet/sink/lav). I suppose I will need less than 5gpm per cabin. I have a 1700 gallon HDPE cistern that I will bury just downgrade from my spring source. I have buried a 1 1/4" HDPE main from the tank location toward the eventual cabin locations. There is a 3/4"(200') branch Teed off of the main to the existing cabin. I buried a wire with the pipe to power a submersible pump in the tank. My intention is to have all components inside the tank for freeze protection. Vertical elevation from tank to first cabin is about 75'. The branch tee is about 250' (linear) from tank. Additional cabins will be appx. same vertical elevation and up to 500' apart.
Questions:
What size sub pump do I need?
Do I need a flow sleeve?
Can I mount the pump horizontally?
Can I put a bladder tank in the cistern to freeze-protect it?
Can I modulate the pump power with a pressure switch in the first cabin?
Could I put the bladder tank in the 1st cabin or does the 3/4" branch size preclude this?(I think it would work untill other cabins were added?)
I was all set to buy a grundfos sqe until I found out the transducer is not submersible! (outrage)
I also have questions about the spring catchment construction, but not sure that is appropriate on this forum!
Thanks in advance for any help guys!
