It was tough to fit this topic of off grid water systems into a 15 minute video! And we totally forgot to mention black and grey water systems. We don’t have to deal with black water because we use a composting toilet. Our grey water system in on the list of projects yet to do . . . we hope to re-use our grey water to water our kitchen garden.
Here are some of the highlights of our learning:
– For rainwater catchment in cold climates, tanks need to be
insulated or sheltered.
– Dark colored tanks will save you the hassle of having to paint
or cover the tank to keep algae from growing inside. There
are plenty of other ways to spend your time on the
homestead.
– An automatic float valve system is ideal for the first flush
when capturing rainwater off a roof. Having to manually
open and close the pipe can be challenging.
– A 3,000 gallon tank would be ideal for a large family, unless
a smaller tank can be filled as needed from a well or spring.
– The largest Berkey available or two Big Berkey filters would be
ideal for a large family.
– Having an indoor hot water tank, as well as a dual hot water
(wood and solar heated) system would be ideal in cold
climates.
– Swale/Pond systems are amazing!

Warframe:
Warframe is a cooperative free-to-play online action game set in an evolving sci-fi world. Join your friends in player-vs-enemy raids across the solar system and master the power of the Warframes. Stand alone or fight together against enemies that threaten your world.
They were called Tenno. Warriors of blade and gun: masters of the Warframe armor. Those that survived the old war were left drifting among the ruins. Now they are needed once more.
The Grineer, with their vast armies, are spreading throughout the solar system. A call echoes across the stars summoning the Tenno to an ancient place. They summon you.
Allow the Lotus to guide you. She has rescued you from your cryostasis chamber and given you a chance to survive. The Grineer will find you; you must be prepared. The Lotus will teach you the ways of the Warframes and the secrets to unlocking their powers.
Come Tenno, you must join the war.
