The watering days roster uses your street number, so you don’t need to worry about your personal apartment or villa number.
For example, if you live at Unit 1, 22 Water Street, you should use 22 in the watering days search.
If your property spans multiple street numbers, like 22–24 Water Street, you use the higher of the numbers to find your rostered watering days. So in this instance, you would use 24 in the watering days search.
