In Sydney, council rates do not include water & sewerage charges. Sewerage is included in the water bill as part of service charge.Rates consist of user type charges such as garbage, water, sewerage, with only water being able to be passed on to tenants.
I can think of few issues with passing whole water bills to the tenants.Water rates - I think these should be in the same category as gas and electricity. For gas and electricity tenants have to pay supply charge, special meter reading fees and then usage.
1. Water is essential. It should never be cut off. Even a vacant property should have water connection. Hence, bill goes to the owner.
2. Unlike power & gas, water companies can't simply turn off their service for a particular property alone.
3. Tenants aren't allowed to change the water fittings without owners permission.
