Grey Water and Green Plants

Greywater is considered wastewater by most people. Greywater is the used water from showers, baths, hand washing, laundry, and dishes. It does not include sewage water, like water from toilets, which is called blackwater. It can have many harmful things, like chemicals from soap, shampoo, and dish liquids. It might also have food particles, bacteria, and whatever dirt or germs from your hands and body when you wash them.

Greywater is released into rivers and lakes, which can harm the environment. Greywater has obvious benefits of saving water and money on your water bill, so in this project/experiment my question was: is greywater good for plants? I planned out that I would water them 4 days a week. I had four plants. They were two different types of plants. One of the plants was fenugreek and the second plant was green lentils. So, it was on Monday, Wednesday, Friday, and Sunday. I watered them with water and greywater. The ph of greywater was 5-9. I did it for one month. After that time period, I got my results. While doing the experiment I found that greywater doesn’t affect the plants too much. It helped it grow. This is one of my results in my experiment and I learned that greywater is a useful way to water plants and help stop global warming. It helps global warming decrease because instead of getting released onto the rivers and lakes which harm the planet it should go into plants.
