Tenant constantly late on sewer bill

[Marty Summers]

I keep getting letters from the sewer department this year that my tenant is always behind on his sewer bill. I get CC'd because my property will get a lien if he never pays. He's almost late with rent each month past his grace period but has never been assessed the 50.00 late fee payment. He moved in February this year. Any suggestions?? Thanks, -mss
