Typically speaking, we can see three types of water at our places. Fresh water or tap water is good water that can be used for drinking. The fresh water when utilized can be categorized into two types. The used water after washing dishes, laundering, or bathing is called grey water. Any other water that is discharged from toilet wastes or kitchen is known as the black water. The grey water usually contains soap, oil, food particles, dirt, hair etc. but it can be reutilized after removal of the same. This has twofold benefits. First, it reduces the demand for fresh water required in a household for non-potable activities, and second, it minimizes the amount of wastewater entering the sewer, drains or septic systems.
Uses of grey water
This water can be used in many ways in homes or commercial building. Usually, commercial buildings may not generate grey water from the shower but sink water can be utilized further.
It can be the best option for apartments or houses where the water consumption is high for non-potable activities. The water generated from the bathroom sink or the water wasted while warming the shower or bathing is not too dirty and can be reutilized. It can be collected in a bucket and can be used to flush the toilet instead of using the flush tank. A little change in the fittings of the bathrooms can help achieve the same and save the cumbersome activity of using the bucket. For example, the bathroom sink can be connected with the flush tank to collect the water in the flush tank every time the sink is used.
Laundry to landscape:
Another simpler way to reutilize it is using the laundry water to water the plants. The water generated after laundry, provided you are not using chlorine, bleach or other harsh chemicals to wash clothes, can be collected in a bucket to replenish the water needs of the garden plants or even the plants on your balcony. The washing machine hose can be connected to a pipe that ends directly in the garden to send the laundry water to the garden every time the laundry is done. In case, you do not have gardens, the water can be collected to water the plants on the balcony or the terrace. If chemicals are used for washing, then this needs to be treated to remove the same so that it may not harm the plants.
Grey water generated from the bath tub:
Love taking a bath in the bathtub and ready to reuse the water, then that is the best place to start with. We usually need a good quantity of water for such activities which can be utilized further. This may require some changes in plumbing. The bath tub and the water drain that carries the shower water, are connected to the pipe that carries the water to the tank set up in the garden, to collect the water and reuse it to water the plants. Grey water stored in the tanks needs to be treated to remove the chemicals or soap from the water for further use.
These simple and smart methods of re-utilizing the water can help us combat water crisis in an economical manner.
