I think it’s a difficult one, and we conserve water where we can in our house, and use conserved water for the garden. BUT we live on an island surrounded by water, and countries like Australia, etc, have invested in proper desalination plants to get enough water where it is needed. We haven’t!
Since privatisation of the water companies in this country, these selfish water companies have sold and destroyed reservoirs, have sacked all their staff who worked throughout the year discovering and mending small and discrete water leaks before they became huge leaks. Some industries in this country are extremely profligate with water.
The selfish people are the senior managers and share holders of the privatised water companies who continue to do whatever they want to make money without giving a hoot for anyone else. In a civilised urban society like ours we MUST have water, it should be free and people could pay extra for water to use as they wish in their gardens, car washing, etc. No need for drinking water to be used in garden sprinklers! ? ? ?
