We get this question a lot. Before you get started, remember that trash wheels require funding, partnerships, a whole lot of support to build. Citizens who want one in their city need to work on bringing people together locally to organize a campaign to fund, build, and support one.
If you are looking for more information about building a water wheel on your local waterway, the next step is to contact Clearwater Mills, the inventor of the trash wheel. They can help survey waterways for suitability and help organizations better understand the costs and other needs associated with building a trash wheel.
