Water Bill Due Question

[Joe Conklin]

I have a rental property where I have my tenants pay the water bill.  My township has residents pay the the water bill every quarter and have a question when the tenants owe me they water bill payment.

The way I have been approaching it is:

I get the bill April 1st for (April-June) and I send them a copy of the bill.  I say that they owe me their payment by May 1st which is the same time May rent is due.  If they do not pay the water bill by that time it is considered late rent.

Is this correct?

What are my next steps if they do not pay the water bill in time? Late fee and send notice to quit?

Curious to see the best approach to this situation is
