Lift Station Issues Due To Tenant Negligence...Any recourse?

[Kevin Howard]

Hi BP Community... I have a nasty reoccurring issue at one of my multifamily complexes. The lift station keeps backing up due to the grinder pump seizing up or breaking completely. I replaced one last year and another one just last week (there are two) each at the cost of $3k. The cause seems to be from the tenants flushing condoms, wipes, tampons, etc... The tenants all sign a list of rules when they move in but this is one rule that's hard to enforce considering I can't pinpoint the unit (4 unit building). Is there anything I can do to recoup the cost other than increasing their rent at renewal time? I'm curious what others have done when you have irresponsible tenants who don't necessarily care? Always appreciate the input!
