A system includes:
Capture
Conveyance
Holding
Distribution
Non-irrigation only systems also include Filtration + Purification
Capture
The capture is the roof of the house
It is the one item that is typically set in stone
The first thing to keep in mind harvesting rainwater is the need to keep debris out of the water system
Conveyance
Getting the water from the roof to the tank is the role of the conveyance system
Gravity + water pressure are the forces that move the water through the
downspouts + pipe to the tank
Holding System
The tanks are the holding system
Polypropylene tanks are the most common + widely available
can either be buried or above ground
These should be sized to meet your water use requirements or you can make a plan to
install another tank in the future
Distribution
The final and sometimes the most complex aspect of the project is
the distribution system
The simplest solution is to allow gravity + water pressure to do the rest
For buried systems: a small submersible pump will do the
trick
Filtration + Purification
A system is intended for drinking water requires a water filtration + purification system
The increase the cost of the system, results in less dependent on outside
provider
You’ll also have the benefit of drinking + using pure
rainwater
As you start your planning:Start by watching your water needs: How much do you use?How are you using it?
Conserve first + start building your system with an eye on the futureWater rates are not going to go down
Rainwater harvesting can be a very strong investment if done wisely
