Tenant water usage increased.

[Lena S.]

Hi

I’m a landlord of 4 units building. We have a problem with water bill we receive every 2 month from city and is $200 more than before! So far, city didn’t increased their water, so we fine with it. More then that, we just established new rents for our new and old tenants, and they are ok with it. I don’t want to even think to increase again. The only what comes to my mind is they have some additional people living with them. 

How do you usually deal with problems like this? I’ll appreciate your advice.
