Cap water is recharged into the groundwater aquifers. Also you’ll notice no water towers. And it’s Tucson… not Tuscon.

If you can't even get the spelling of a major city in Arizona correct, your content is... as the kids like to say, "sus".

You’re still struggling to grasp any of the content. Your whole reply is only focused the response to your unrelated spelling dunk.

Having such superficial interactions with the world is congruent with believing the meme that all of Arizona drinks well water though.

I hope you do take some time some day to learn about the state you grew up in. The water projects are quite impressive engineering because there is no other option. The rural holdouts that pumped their groundwater dry learned that lesson the hard way.

Look dude it is you who doesn't understand how it works, at least as far as it concerns Tucson: https://storymaps.arcgis.com/stories/70f626809fd84e228c0f32a... https://www.tucsonaz.gov/files/water/docs/coloradoriver.pdf

They tried "to the tap" and it pissed everyone off because the river water leeched out all of the rust in people's pipes.

And not just short showers, but managing the amount of time the water is actually running. Here’s my strategy for an efficient shower: 1. turn on the water, get in, rinse down, soak a wash cloth 2. turn off water 3. lather hair with shampoo 4. lather wash cloth with soap and scrub body 5. turn on water and rinse down The majority of the time we’re standing in the shower, we don’t actually need the water to be running…

Ufff. I’m not doing that when it’s 4c outside and because I turned the heating off at 9pm my house is 14c. I need the shower to warm me up and stop me turning the heating on early in the morning

Turning off your heat is costing you money. You don't want to cycle all the heat out of the building and then have to warm it back up.

It's called heat capacity and the materials themselves require so much heat before you feel warm.

TL:DR Turn your heat down, but not off. Save money

I just want to put in a word for standard microeconomic theory. If our water (or energy) use in aggregate suggests to the govt that our consumption needs to go down, then raise the price of water (or energy) across the board till it does. Individuals can choose which of all your amazing water (and heat) savings ideas they feel would best suit them.

The problem in reality is that people have wildly different amounts of disposable income and that there are more and less important uses.

Rich people use drastically more resources. If you want to curb their resource usage with price you would need to increase prices so much that poor people can’t afford the resource anymore.

E.g. you want to stop people watering lawns during drought, so you make water so expensive that rich people cannot afford it anymore, but then poor people cannot afford to wash hands, shower or flush the toilet anymore.

One solution is to have the first x units of the resource cheaper, similar to progressive taxation.

There may also be problems with sanitation rules, only a minimum of water should sit in the pipes, and then ideally hot our cold but not luke warm.

Got a link (or explanation) for that temperature stipulation?

Yes, as tempestn explained this is to prevent bacterial growth, especially Legionella. Otherwise this can be a problem in areas where tapwater is not chlorinated.

Alas, the UK has the twin problems of poor building codes and lots of old housing stock that nobody puts much thought into maintaining. In the latter case, people will take single skin brick buildings and apply "vapour control" materials outside the building, thus ensuring moisture is locked into the bricks. Then they wonder why they have damp, etc. Alas, we are a very silly country.

What kinds of material is added to exterior brick? Insulating panels?

Sand and cement in my house's case. Rubbish insulation, utterly impermeable - combined that means the dew point (where water vapour condenses) is within the brick. The freezing point is too, and bricks are not exactly flexible when saturated with expanding and contracting substances.

Some insulating panels are also dreadful, but on the whole a semi-competent installer will do the thing right. The problem is, some aren't even that good - we're talking a minimum bar of an NVQ level 2, and that's if people don't decide to just.. go self employed and do it without training. No regulation at all, and there can't really be any until it is a licensed occupation.
