Tenant didn't report running toilets

[Christy Jones]

I am new to being a landlord and want some advice here. I got a water bill that is normally around $65 a month that was $400 this month for a rental property. When I sent my property management group to look at the meter, the tenant told them that the toilets have been running non-stop. He failed to report this so we could correct it. Last month the consumption was 29K+ gallons and this month we are already at 10K gallons and looking at another $400 bill I am sure. Since he failed to report, is he liable to pay the high bill? The property group hasn't responded to me and I would like to get a general consensus here.
