Potable aka drinkable water, costs here with various environmental mark ups 0.94 Euro per cubic meter (35.3 cubic feet at 1.20 USD at current exchange rate). Recounted elsewhere we have a system in the house that captures the water from the air conditioning system when on (only when inside is over 27C these days) .When on it easily produces 50 liter of perfect clean plant water per day. When showering we put a bucket under the tap until the warm water comes out which also goes to the plants or to flush the toilet, which has small and a big flush buttons. Of course the barrels collecting the Airco water also capture the rain water, which is very little in the summer months, so we are careful and conscious. Handwash and airdry the dishes saves and is healthier too ... drying cloths quickly load up on bacteria (visualizing some folk clinching their teeth).

Over in the Netherlands new urban developments get now separate systems for toilet water and other affluents from kitchen and shower, too expense of course to retrofit, but advanced thinking how to better deal with the contaminants whilst it passes from mouth to sewer back to the treatment company all with lesser availability per capita as populations grow.

So, what's water costing at your place and what are you doing to preserve water and reuse where you can? Is it save to drink out of the tap or do you boil first and only consume water from pet bottles of which millions end up in the lakes and oceans each day, particularly the caps.
