Do you know how much water that we waste a year.
We'll you know how we waste a lot of water. At this school there are sinks that you push the button and the water keeps on going. So we thought to add censoring sinks to all the restrooms in the school.2%of earth's water is fresh and we need to conserve it.
The reason we want to save water because we know that there is less then 2% of the water is fresh water and the rest is salt water so we are think of putting motion sensors sinks in all of the restrooms.
18 restrooms in the whole campus. There are three sinks in each restroom. 3x18=54. The cost is 118.69 per sink. The total cost is 6409.26.
