With a RO water purification system, we get not only clean and tasty water but also protection from life-threatening water-related diseases. But there is one major drawback of using RO water purifiers.
It is the excessive wastage of water. If you check, an average RO water purification system will waste approximately three liters of water for every liter of purified water.
Six Ways To Re-Use RO’s Rejected Water
1. Washing Cars
A single car wash will consume around 14 liters (this is using a bucket) to 75 liters (using a hosepipe) of water. So, washing cars every day will lead to wastage of water.
If you are using an RO water purification system at your office or home, you can store the wastewater in a bucket or tank and reuse them for washing the car. Water with a TDS level of 1200 to 1500 PPM can be safe for washing cars.
2. Watering Plants
You might be a person that loves gardening or planting plants in pots. The wastewater you get from the RO purifiers can be used for watering the plants kept in the terrace or indoor gardens.
Frankly, this is a great tip for people living in urban areas where the TDS level of the municipal water is low.
3. Washing Utensils
Another best application of using Reverse Osmosis (RO) wastewater is for washing utensils. All you have to do is store the wastewater in the bucket or tank and then place a bucket to collect the RO wastewater near your kitchen sink. This can be used for cleaning your utensils.
4. Mopping Floor
You can use the RO wastewater for mopping the floor, and this will surely save tons of liters of clean water every day. You might be having a bigger house, and this procedure will help save hundreds of liters of water every day.
5. Pre-Rinsing Laundry
The waste RO water can be used for daily laundry. However, you do have to keep in mind that high TDS water won’t be suitable for certain delicate fabrics. Most of the homes in India use a washing machine, and it leads to the consumption of a lot of water and time.
You can create an overhead tank for collecting the waste RO water and use this water from the tank into your washing machine. Frankly, this is a great tip if you have a semi-automatic or twin tub washing machine.
