Wells are underground water sources that can provide hundreds of gallons of drinkable water; however, installing a well can cost thousands of dollars. In bamboo plants, water is pushed up from the roots to the leaves in the morning for photosynthesis. Due to this process, the bamboo stem cavities, which store water for the plant, will contain high amounts of water. By drilling a hole into the stem wall of the plant, water can be collected, cleansed, and extracted from the plant for an affordable price. Unfortunately, taking water from bamboo plants damages them; if too much water is taken, the plant’s health will deteriorate, resulting in the decline of future water production. With this new water collection technology, we researched how the maximum total amount of plant water collected from bamboo plants each day affected the possible total amount of water collected over time.

The hypothesis was ‘if the maximum amount of plant water extracted from bamboo plants is decreased, the total amount of plant water collected will be higher, and we would be able to collect the water over a longer period of time’. The plant’s health will not deteriorate as much when less water is extracted from the plant because it will have more recovery resources to further collect more water, making the plant water resource more sustainable. An example of resource sustainability is shown by tree sap industries. To collect sap, people use drills to make tapholes in the outer layer of the tree. However, since vital carbohydrate-transporting cells are located there, too many tapholes can kill the tree, rendering it useless for producing more sap. In order to prevent lethal damage towards the tree but still collect sap, these harvesters only drill a few tapholes so then the tree can produce more sap in the future.

To test this experiment, 9 bamboo plants were planted into soil and had water extracted from them daily. A drill was used to create small holes in the bamboo stem wall and reveal the bamboo culms which water is stored in. Once the defined amount of extracted water was reached or there was no more water inside the plant, the holes would be plugged and the this amount would be recorded.

The results of this experiment matched the hypothesis; when the amount of water that was extracted decreased, more water was able to be collected from it over a longer time period. This shows that a sustainable water resource can be made if 5 milliliters of water is extracted from each stalk every day.

This technology and data is an affordable, effective, environmentally-friendly, and sustainable method to collect resources. In regions where water is unavailable, these bamboo plants can be an affordable way to purify and extract water from the ground. With the data from this experiment, water can be extracted sustainably without the death of plants. Since bamboo plants reproduce and grow quickly, bamboo plants that are killed for wood, paper, food, clothes, et certa can be replenished.
