Getting Clear on Greywater:
Advantages of Nature-Inspired Water Systems
Lecture by Art Ludwig at the Water Conservation Showcase
4-5 pm Tuesday, May 25th, Pacific Energy Center, San Francisco California
Description
Why pollute waterways with wastewater and nutrients, when they can irrigate and feed plants?
Reuse of greywater for irrigation is part of a fundamental solution to many ecological problems.
This presentation will explain the benefits of greywater reuse, and how plants and soil achieve such spectacularly high treatment levels.
Code issues and other limiting factors will be addressed, with special mention of the greywater regulation revolution in Arizona and New Mexico.
Strategies for realizing the immediate and future benefits of greywater in existing buildings and new construction will be explored.
Questions will follow the class.
