Water is a human right, yes

But, overuse of water due to lack of cost is a prevalent reason for the water crisis in this country. Our infrastructure is dated and cannot cope with the demand. Based on the occupancy of each residential and commercial property, a daily/weekly/annual base allowance should be calculated (toilet flushing, washing machine, dishwasher, etc. all home appliances and general usage taken into account) - should be fair and not restrictive, but ample to prevent abusing the current limitless quantity of water. There should be allowances to apply for an extra occupant etc. if having guests stay for a period of time, etc. if this would cause the dwelling to go over the allowance.
Once over the stated allowance, a flat rate should be charged per litre/gallon, etc.
