Including water bill to rent, how will tenants react?

[Nicholas Jose]

Good afternoon.

My tenants have been paying for their own separate gas and electricity bills, but when it comes to water, I'm the one that's paying (since there's only one meter for water). I've been thinking of increasing my tenants' rent so that it includes the water bill; however, they've been paying on time and I'm just not sure how they'll react once they see their rents go up: angry? understanding? How should I explain it to them?
