The average person uses 3 units of water per month. So, a family of 4 would use 24 units per billing cycle. Your actual consumption may vary depending on lifestyle and season. A leaky toilet or water leak can dramatically increase your bill. Bills also may be substantially higher during warmer months, when you may use a lot of water outdoors.
