Irrigation water supply

Has anyone heard of a non potable water supply for your house. Someone I know lives in Portugal and the have two meters, one potable for drinking and one for irrigation.
Obviously the non-potable is much cheaper.

Never heard of it for personal use in houses only places like parks etc. Good idea though

Different areas have different systems,for crops
Some areas are on meters for irrigation water,
Some pay a fixed yearly charge unmetered
I think it goes off the size of your land area,

What about private houses?

Before we go any further, why would you even need non potable water in a private house? Unless you have acres and acres of garden and an olympic sized swimming pool you constantly change the water in, why would you need two sets of pipes, two water meters, two lots of taxes and standing charges when water here is the cheapest part of the bill?

Agricultural water here comes from either the river or the desalination plant. Imagine the cost of getting any of that supplied to private houses?

99.5% of water in Spain is potable. Pointless even considering non potable water for a private house unless it's an estate type one.

Stick water butts out the back in case we ever get some rain.

I understood and was told the desalination water was solely for domestic use only ,but you are more informed &knowledgeable than me,on Quesada matters.

Good idea ?

You should read the Spanish papers, especially the local ones. Desalinated water is being used on agricultural grounds and Murcia has taken much of it for the land around there.

There has been ongoing arguments for some years as they decided to stop the transfer of the Rio Tajo to the Segura forcing farmers to pay some 3 times as much for desalinated water, thus putting their cost up, than for river water.

Just one bit from the people who run the desalination plant
"Europe’s largest desalination plant. Average flow: 240.000 m3/day. Beneficiary population: 1.6 million. 50% of the production is used for irrigation and the other half for domestic consumption."

Ah! so 1.6 million people benefit as domestic supply, 50% goes for irrigation,
