(061) Water and Aquaculture – Greywater: Restricted Access


Water seems plentiful, but that’s because it’s made artificially cheap. It’s the most important element in our lives, but the government has subsidized the cost of water, making people think there’s a neverending supply, and so we waste it easily. Greywater systems can reduce our water usage by at least one-third. It’s an old idea, but new to mainstream minds.

In this lesson, Roy Nordblum explains greywater percolation tests, and introduces a variety of ways to design and use greywater systems.
