RUBs are not based on consumption, therefor tenants/residents lack positive reinforcement (lower overall rental expense) to conserve water or even report a cycling toilet. 

I wonder if that is legal or not or at the very least not ethical or moral..

You as the landlord have legally and morally obligations, but they as the tenants also have specific obligations.

@Mario Morales, a few thoughts:1.

My coaches never taught us to treat people that way, nor would I either way because I morally know better.  

@Mario Morales Make sure the landlord agreement is in place with peoples gas.

Yes I have a moral outrage in situations like that.

The lender wants to run your credit score to determine whether you're Dilcia Morales or not.

While this might seem fair on the surface, it may not accurately reflect each tenant's actual water usage.Usage-Based Billing: Implementing a system where tenants are billed based on their actual water consumption could be fairer.

Also, morals do come into play, that is an aggressive policy to have in place.
