I've just got my first rates bill and it has the wastewater charges on it that I need to pay but it also says on it "Water rates will be separately invoiced twice yearly based on the consumption recorded by meter at $1.29 cents per 1000 litres". When that bill comes I guess I'll pass it on to the tenants cos if they use shitloads of water I don't want to pay for it! I guess check with your landlord as it's a usage thing like power or phone.
its a standard clause in a residential tenancy agreement. The section that contains rental amount, term of rental etc also contains a provision for who pays the water rates. You either have to cross out 'tenant' or 'landlord'
Its usually about $250 per year for an average household so $75 for three months is about right.
