RAINWATER COLLECTION SYSTEM

One of the standard approaches to minimizing the water consumption in buildings is storing and using rainwater.
I will differentiate between the following terms:
Rainwater
Greywater
Whitewater
Blackwater
I will cover some basic approaches to water treatment and filtration.
In this video, I will guide you through a specific instance of an underground rainwater collection system (water utilized for flushing toilets) and its install process showing own photos from the construction phase.
In the end, I will cover my user experience with the system after more than five years of use as well as its local specifics.
I will also mention things that I would do differently today.
What are your thoughts on rainwater collection systems?
Do you have or plan to install one in your property?
Enjoy.
