The new cistern's walls are up. We're just waiting for the rain to stop, so we can put in the liner and make the roof.
In the event that it might actually rain this year, we have been doing some work on our water system, including a self-cleaning overflow.
Catching rain water from your roof is the most accessible source of water off-grid. Everyone gets at least a little rain, and if you size your roof and storage to match your annual rainfall, you need never go without water.
