(061) Water and Aquaculture – Greywater: Restricted Access

PLEASE REGISTER TO WATCH THIS COURSE.

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.

California is a pioneer in greywater legislation, being the first in the country to create a greywater code. Having legal support for greywater installations means real water conservation. In this lesson, Roy Nordblum explains greywater percolation tests, and introduces a variety of ways to design and use greywater systems.
