Water

A reliable, clean water source and efficient water management is essential to a healthy life and successful farming.

Drilled well

 * Requires pump, may be very expensive to have drilled by third party.
 * Often pre-existing on property.
 * May be DIY bored through softer materials down to around 50 feet for great savings versus paying for a driller.
 * Mild treatment or filtration may or may not be needed.

Local water body

 * Generally requires pump.
 * Local stream, lake, creek, river - logical water sources.


 * Will probably need some treatment or filtration.

Rain

 * Unpredictable
 * May not be available when needed
 * Easy to collect

Recycled from home

 * Gray water from showers, laundry, dish washing et cetera, requires treatment (duckweed pond)
 * Black water not reusable for common tasks - water separated from waste and used for plants, solid waste used for composting heater.

Duckweed Pond

 * Filters gray water and generates excellent protein-rich food for people, livestock or fertilizer.
 * Needs to be scaled to the volume of gray water produced by community
 * May die off if starved, necessitating micro-management

UV bulbs

 * Kill pathogens

Activated Charcoal

 * Can be manufactured by commune
 * Removes toxins and impurities

Mechanical separation

 * Sieve, screen or membrane
 * Removes larger particles
