Greetings to you friend!
You have told about a very good information regarding the water because it is essential part of our life and our body lives on water about 75% almost that's why you guys can have an idea that how much it is important to take water and I agree with you that at least two litres of water per day are required to our body and they are about 10 glasses of medium size that will normally use in our house.

On the other hand I agree with you that it is very important to drink clean water but you cannot say that for other purposes like in washrooms we know that we also need water so we should use clean water for this purpose also because in washroom if we don't use clean water then we will be at higher risk of getting urinary tract infections because there maybe many pathogens that may infect us.

So cleanliness of water is very important and also to take care of each and every drop of water is important because it's a big blessing and we should not waste it and we should gives water in a proper way means I have seen many times that people often open the tap while doing the brush this I am just giving an example so you guys can have an idea that how much in this way and in this little activities of our daily life we are losing this big blessing so they should be a proper use of water.

Well you participated very well and I wish you a lot of success.
