Definition of Town Water
Once considered to be drinking water of the first water, but now considered to be that which passes through a water meter. This watering down of the concept started with the water people testing the water and then going to water so that town water can now originate from water closets, or indeed, from watering the horse. It is doubtful if the phrase town water will hold much water in the future, as water tanks result in it no longer remaining above water. Many consider town water to have already become water under the bridge.
