5 Creative Ways To Use Wastewater From Water Purifiers

Most of us rely on water purifiers to get clean, safe, drinkable water. However, in a country where water scarcity is a growing concern, we often end up wasting more water than we realise. For instance, how many of us have truly thought about what happens to the wastewater that gets discharged by RO purifiers? While we enjoy clean drinking water, our water purifiers release litres of wastewater throughout the day. Although that water is not fit for drinking, it is far from useless. In this blog, you will read about 5 such creative ways to use wastewater from water purifiers.

1. Mopping Floors

Although the wastewater from water purifiers is not fit for human consumption, you can still use it to clean your home. This reduces your dependence on fresh water and saves it for future use. You can use this discarded water to mop floors and wash reusable cloth dusters. Make sure to use a bucket to collect the water and a few drops of any disinfectant. 

2. Washing Vehicles

Can you guess how much water it takes to deep clean vehicles, like a car, bus, or bike? Well, neither can I. But I am pretty sure that it's a lot. So, instead of using fresh water, why not use the discarded water from water purifiers

For this, you'll need a bucket and a mug along with other cleaning supplies to start the cleaning process. You can also connect another pipe with the wastewater discarding pipe to collect the water in a big container. However, avoid the water from drying on glass surfaces to prevent unwanted marks.

3. Pre-Rinsing Utensils To Discard Food Waste

Another interesting way to use discarded wastewater from water purifiers is to pre-rinse utensils. Collect the water in a bucket and rinse off leftover food particles from pots, pans, and plates. This small habit can cut down the requirement of fresh water to wash utensils. 
Although it may seem insignificant now, it can lead to big results in the bigger picture. Moreover, it is especially helpful in Indian households where three meals mean dirty dishes throughout the day.

4. Water Plants Or Lawns

The next creative way to use discarded water purifier water is to water outdoor plants, especially those that are less sensitive to a high salt content in the water. Avoid watering your indoor plants like succulents, as this water can potentially harm them in the long run.

Additionally, you can also use this discarded water to spray on your patio, lawn, or areas with a good drainage system. This will help cool down the pavement in summer and reduce dust particles.

5. Soaking Laundry Before Washing

Before running your machine or hand-washing your clothes, the discarded water from water purifiers can be used for soaking clothes. You can use it for heavily soiled items like kitchen dusters, bath towels, and bedsheets. This step loosens up dirt particles and reduces the need for extra detergent or long wash cycles. Make sure to use regular water for the final wash.
