Pump/Filter House Near Catchment Tank

[beejee]

I searched around a bit within the building-in-puna topic and didn't really find anything along the lines of what I'm envisioning.

My goal is to have a traditional catchment system with the pump/filters/etc located in a pump house adjacent to the catchment tank away from the house. Having no hands on experience with catchment systems I have no idea of any of the basics. What is the average size of the output line after the pump/filters/pressure tank etc? 3/4" copper line? How about the pump house, any advice on adequate internal dimensions to house all the components?

Of course, also very appreciative of any advice good or bad about the approach. Thanks!

Edited: To fix typos and better explain goal.

Good document that covers catchment systems http://www.ctahr.hawaii.edu/oc/freepubs/pdf/rm-12.pdf

Make sure you can still tell if the pump is running. A big leak can drain the tank and burn up the pump. Also a pump going on when no one is using water warns of a problem somewhere, leak, defective foot valve, etc.

Very good advice PauHana, thanks. After reading the document above specifically regarding normal pump operation and troubleshooting, it's evident that being able to hear the pump is a necessary evil. Now planning to locate the pump/filter assembly adjacent to the house.

You could do something else, like rig an LED light to come on inside the house somewhere where you'll notice it if the pump is running. It's not uncommon to have a well pump far from the home and being underground they can't be heard. Catchment tank pumps don't necessarily have to be heard, but its an excellent idea that you would have some method to know its running. I know somebody who didn't realize their well pump was running all the time until she got the electric bill and had to figure out why it was so high. She was lucky she didn't burn the pump up.

Any time you install a pump that may fail due to lack of water flow INSTALL A LOW PRESSURE CUT OFF SWITCH !!! cheap insurance to save the pump (sorry for yelling , learned the hard way many times ).

@melo1112 Great advice! I'll definitely add a low pressure cut-off to my system. Thanks for the pointer.
