Commission idea - Wasteful Water

When on the subject waste i automaticly think of rubbish and recycling, however i dont want to base this project on this theme. Instaed ive been thinking of waste in the houshold, for example i come from a rather large family who use a lot of water every day. Focusing on water i think of the amount that i myself and others waste. For example half drunk galsses of squash is a common thing to see, it doesnt sound like much but it goes to waste every day and is one theme that seems quite relevant to research into..
Also i myslef have many showers and some family members prefer a baths, however this again can waste water as baths use more water to fill and can also be overfilled easily. Washing up can also be a pain, our dish washer uses a lot of water also and sometimes the washing up water goes to waste which could be used to water the plants or for another purpose, as well as the amount the washing machine uses also.
The point im trying to make is that my household generally uses a lot of water but it seems like half of it is wasted, it makes me wonder how much water gets wasted in my area in other houses. It must be a considerable amount.
If i could represent wasting water in some way it could be quite interesting. Ive found this artist who is a 'Liquid Sculpture' Martin Waugh captures digitally the moments when a drop of water hits water. Ive found it quite interesting and beautiful to look at. An example of his work is below, it's not the theme i am looking for but it caught my eye when researching.

The reason why i picked this photograpgher top look at was because of the way in which he captures the water droplets and the colours and experimentations that go with each image. They look not only beautiful but each unique. Another photographer who takes very similar images is Markus Reugels, famous for capturing the world in a droplet of water and his other water based images.

When looking at this photographer im obessed with the complabiltiy of the image as well as the amazing colours of substances he uses. He is very similar with to the previous photographer Martin Waugh. Because I am using film for this project i cant take images like this or after researching them do i think they resemble waste in anyway so I'm moving on from this photography.

My Idea
Just as a simple idea i have in mind, i could represent wasteful water by having many half filled glasses as a focus point of the camera. Maybe the camera angle could be directly above or straight so the curved glasses and the magnifying of water will emphasise the amount being represented.
Maybe i could use just one glass frosted or brittle, all representing wasteful water.
