RAINWATER CALCULATIONS

IN THIS ASSIGNMENT WE CONVERTED RAINWATER PRECIPITATION FROM INCHES TO GALLONS. THIS IS IMPORTANT FOR RAIN WATER COLLECTION AT THE SITE. BY CALCULATING THE RAINWATER ONE CAN DETERMINE IF THERE WILL BE ENOUGH GREY WATER TO FLUSH TOILETS AND DO LAUNDRY.

IN THIS ASSIGNMENT WE CALCULATED THE AMOUNT OF WATER A TYPICAL FAMILY COULD SAVE VIA WATER USE REDUCTION. BY CHANGING THE FLOW OF THE SHOWER HEADS AND FAUCETS IN A HOUSEHOLD, A SINGLE FAMILY COULD REDUCE THEIR WATER USAGE BY MORE THAN 50%.
