Class During the Pandemic

During these strange and unprecedented times we acknowledge that we need to stay safe and be considerate of our community. Water is also a critical component of any healthy and resilient community and because of the the increased interest in this field, we want to provide our community with the knowledge and tools to be the change in the coming years.  

This said:

  • We have limited the class size this year to 10 people to adhere to public health mandates.
  • We have moved some of our content online and in-class days will be primarily outdoors.

I learned practical skills to be able to install water harvesting systems at my own house and gained a foundation of knowledge that I can keep building upon into the future.
