Hello, all! I’d like to map the plumbing and sanitation systems in a city, with clear delineations between when certain sections of pipes were installed, what materials they are made of, who the manufacturer is, and so on. It occurs to me, however, that there may already be a resource to help with that. I haven’t had any luck finding it. Is there a service that provides this information?
If not, what are the best practices you would recommend for building a map like this?
Thank you for any help.
