Rain Water Harvesting: Water Self Sufficient Home

Step 5 The pump closet

This is where is gets a little more complicated but not much. At this point all the rain water from the roof goes and fills up the tank, pretty simple.

The smaller pipe is run to a pump closet that holds a water pump, pressure (ballast) tank, and filter.

Red Valves are from the OUTSIDE and blue valves are for water heading to get used.

Pump sucks water in, and keeps pressure in a ballast tank (next step) and then the water is forced thru the sediment filter and into the house

Wouldnt particularly use plastic pipe (PVC) for high pressure water, maybe for the feed for the pump. for the high pressure side I would use either copper or plastic barrier pipe (JG Speedfit) :)

Great work!  I'm looking to build a similar setup - how are you controlling the pump to fill the pressure tank?  I'm going to use this for garden/fruit tree irrigation so I need it to work with my sprinkler controller, any suggestions?

 there is a pressure sensor on the pump, so it turns on and off based on the pressurized side of the system.
