Is there a way to find out if the following states demand water reclamation: Ohio, Kentucky and Indiana?

All states do, it's a Federal statute (Clean Water Act). However, enforcement is by local authorities, so this varies from state to state as well as locale to locale.

Here in CA, it is enforced at the city level. Some cities are catching on that they can use it to generate revenue.
