How to Utilize RO Wastewater : Hello Friends, How are you and what are you doing in this pandemic situation? I hope you are doing just fine and I recently come across a very important fact that I want to share with you, I don’t know if you observed or not, but RO System of these days waste too much water. I actually measured the wastewater it eliminates before even the filtration process and eliminated water was 3 litres for every 5 litres. That is Insane Water Waste because, usually all these water directly go to the sewage system, without any use.
You Can check my article Eco-Friendly Inventions related to Water, and you will observe that I am a bit sensitive about Environment things, and that’s why I did a quick research in this matter before putting anything here. So, After a quick research, I also come across a state that “An average Reverse Osmosis (RO) purifier wastes approximately 3 litres of water for every 1 litre of purified water”. That means only 25% of water is purified and 75% of water comes out as waste.
Now, You will ask why so much water is wasted? so I found the reason as well and here it is,
Why so much water is wasted in RO system? Is RO wastewater safe to drink?
Most of the Reverse Osmosis (RO) purifiers use membrane technology to filter impurities and solids dissolved in the water, because of the high level of impurities impure water is directly filtered out and it is known as wastewater or rejected water. The rejected water is not good for drinking or bathing and I would like to mention here that the percentage of wastewater varies according to the RO purifier being used.

# Important Information about RO wastewater
As you guessed already that I am going to tell you some way to proper utilization of ro reject water, and yes you are correct, it is the next topic here but before that, I want to share some important information RO Waste-water, the same is stated below.
- It is essential to check the TDS level of the rejected water before reusing it for other purposes.
- If the TDS level is too high, then it is not the best idea for utilizing it in most of the applications given below.
- For more safety, and to avoid any risk, if possible, test the wastewater for the presence of inorganic and chemical stuff like Sodium.
- In addition to the TDS level, we would like to suggest checking the ph of ro reject water, it doesn’t matter allot but there is nothing harm in it. You can easily find websites for ro reject water parameters, additionally, videos are also easily available on youtube to check the PH level of the wastewater.
Possible ways to Store the RO Waste Water
- If you are thinking to store the water in a bucket then let me tell you that if your daily requirement of purified water is 20 litres then on an average your RO would generate around 40-50 litres of wastewater, and even if you use a big 15-liters bucket, you would need to empty the bucket 4 times in a day. it is an option but I am not gonna do that.
- I personally extended the RO wastewater pipe using a saline pipe and dropped it in a big tank placed outside our kitchen.
- When there is no big space available to put a tank around the RO, Use a small bucket and collect wastewater in it then connect a submersible pump for taking water from this small bucket to the tank or big bucket.
