I recently read your article on the Emma Park project. I think that retrieving the water there would be very beneficial to the city. The main problem is funding as I see it.
One way the city could get money for the project is the city could host a fundraiser or some kind of event to get the community more aware of the project and interested in it. A donation jar could be placed at the city office or other public places. You may want to present some of the ideas in front of the city so they can get proper funding for the project.
