Laura Allen, Greywater Action
Greywater reuse is an increasingly popular method of water conservation in the west. As temperatures rise and droughts become more commonplace, greywater reuse can offer an affordable, low-energy solution to keep landscapes green and productive throughout the summer months—without consuming precious potable water. It's time for greywater reuse to be an viable option for residents of the Pacific Northwest. What are the barriers here to implementing these systems in our homes and landscapes? Are they codes and policies? Lack of education? The “yuck” factor? And how can we overcome these barriers? This talk will highlight the current, tried-and-true systems available, and discuss the codes regulating them. The talk will include: Overview of popular residential greywater systems, including their costs, complexities, capabilities, and limitations. Regulations in Washington and Oregon, as compared to California andincentives and education programs for greywater in the Pacific Northwest. Laura Allen, author and co-founder of the California based organization Greywater Action, has been on the forefront of providing public education and policy change activism around sustainable water practices for over a decade.
