*Wondering what sliding-scale means? A sliding-scale fee means that participants choose the amount to pay along the scale (between $50 and $150). People who can afford to pay more help subsidize people who can’t afford it. This helps us keep our workshops affordable to more people. We thank you for paying as high as you are able to on the scale.


Whole-House Residential Greywater Systems

  • March 16th

Whole house greywater systems collect greywater from showers, sinks, and washing machines, filter it and distribute it through drip irrigation. Systems like Nexus E-Water treat the water so it can be used for toilet flushing or spray irrigation (NSF 350 certified), IrriGRAY systems can be monitored on your smartphone, and GreyFlow’s filter is cleaned with compressed air (bypassing a common concern from regulators regarding potential cross-connection issues). Learn about these three different whole house greywater systems in this informative webinar, with founders of the companies presenting on their products. We’ll cover costs, maintenance, installation requirements, water savings, and general pros and cons of the systems.
