We all are familiar with the current water crisis scenario across the globe. By keeping this scenario in mind, it is necessary to install the best water purifier in the house. There is no question about the qualities of the RO system to purify water. But the main disadvantage is that RO reject water is a nightmare for any household using the system. RO Water purifiers provide effective purification of water, but also contribute to excessive wastage of water.Water is among the essential natural resources available. We’re going through a process where a shortage of water is suffocating common citizens. Does that mean you’re not allowed to buy a RO purifier? Or is there a way around that? There is, of course. We’ve written this ultimate RO wastewater guide to address this problem. Read this guide and contribute to resolving the water crisis issue

Why is RO Waste Water created?
All of us are worried about the quality of water supplied through groundwater, municipal, and borewell systems. These problems are related to the increasing levels of microorganisms and pollutants in the borewell systems and the diseases they cause. Because of all these factors, more and more people have switched to cleaner water purifiers. Reverse osmosis (RO) is one of the most widely used techniques for this reason. The below-mentioned points are something you probably didn’t aware of:
- The RO membrane technology helps in filtering out the unnecessary impurities using extra additional water.
- The additional available water helps in cleaning out the filter and is then treated and released.
- Several research studies have concluded that RO purifiers discharge three times more water than purified water. This means that the RO waste water ratio is about 80 percent of the water coming to the unit.
What is the risk of using RO Reject Water?
The RO wastewater discharged is a no-go zone, according to water experts. This wastewater includes a significant content of total dissolved solids (TDS), which makes the water not drinkable. This water is also not suited to do any kind of household activities, and, in some cases, it is not recommended for bathing with RO water. Besides, the volume of inorganic salt and organic matter in this discharge is very significant. This just adds up to why the treated wastewater is useless.Water with a high TDS level also produces foul smell and taste, making it unhealthy for a drinker. Also, it has been related to some severe diseases, such as stunted development, reproductive failure, and more. The use of wastewater for daily tasks can cause stains or leave salt residues.
7 Simple and proven ways to reuse RO wastewater
If you have installed the RO system at home, in the workplace, or anywhere else, we suggest that you store the discharge in a container. You can then reuse it in a few easy ways to cut down the amount of waste. Moreover, every little droplet counts!
You should use RO Reject Water for your everyday tasks, such as mopping and cleaning the floors. However, make sure that the wastewater is combined with some fresh and healthy water. Using RO to reject wastewater for mopping the floor is simple and would undoubtedly save tens of liters of clean water nearly every day. If you have a larger home, the savings could reach hundreds of liters daily. If the amount of TDS in wastewater is high, i.e., more than 2000 ppm:
- Dilute the excess RO water with the same quantity of tap water. Since plain reverse osmosis wastewater with high TDS may stain or leave salt particles on the surface.
- Using RO waste water for mopping the floor on alternating days. This decreases the risk of any stains or salt deposits.
Wash Your Car
Are you aware that it takes about 14 liters of water to wash your car? Bearing in mind the shortage of drinking water, using too much drinking water to wash cars seems a waste and no less than a violation. A smart way to conserve freshwater is to replace it with a filter discharge. What all you need is a bucket or a waste tank, and your car can have a much-needed wash! If you use a water purifier in your home or workplace, you can easily store the wastewater in a tank or bucket and reuse it to wash your car. Water with a TDS level of 1200 – 1500 PPM can be used safely for car washing. If the TDS amount of the wastewater is high, the tap water may be combined to dilute it. This is supposed to lower the TDS level.
Watering Plants or Home Garden
The most effective and efficient use of the RO Reject Water is used for gardening purposes. Vertical gardening is a new phenomenon and a popular trend these days. You may use the balcony or the terrace wall to grow plants. Available high nutrients and minerals in the water can help your plants to grow and bloom. However, this is desirable for urban areas only where the TDS levels of municipal water are generally lower. Use a can or bucket to store the expelled water. Use this discharge for indoor and outdoor storage plants. Even then, we recommend that an initial trial be conducted to ensure that there are no harmful effects. It is an important measure to understand how each plant responds differently. Here are a few more things to bear in mind.
- Get a TDS estimate of the water being expelled. Acceptable levels of irrigation and agriculture TDS are 2100 PPM
- Besides, the sodium level should also be calculated to avoid long-term damage.
- High sodium present in water can affect the texture and structure of the soil affecting plant growth in the process.
Another beneficial use for Reverse Osmosis wastewater usage treatment is to wash your utensils. Since most people are installing the RO filters in the kitchen, what better place to use the wastewater than the sink? Easily store the wastewater in a tank or a bucket, but make sure that you place the bucket to collect RO wastewater near your kitchen sink so that it can be used quickly when you wash your utensils.
Although this is a total no-no for bathing, you can use the reverse Osmosis wastewater usage to flush and clean the toilet. Flushing takes 6 to 7 liters of water instantly down the drain. It’s a huge sum, given the number of times we flush every day. This natural tap water wastage can be reduced by using TDS water for flushing. To use it properly, dump it into the cistern of the toilet seat. You may also dilute it with daily freshwater to clean a toilet seat and porcelain tiles.Moreover, as stated above, salt deposits and discoloration are common effects. It is essential that you closely watch any signals. To avoid any harm, this method is recommended for periodic cleaning only.
Do you have pets at home that you bathe regularly? Did you know that you might use RO reject water instead of discarding it? Few pets are also vulnerable to rough water. For this reason, we recommend that it be diluted with ordinary tap water. Often, make sure to brush the pets dry gently afterward.
Usually, laundry washing requires a massive amount of water that goes to waste. Alternatively, RO wastewater can be used for pre-rinsing. Dissolved salts in this water help eliminate stubborn stains. However, bear in mind that delicate fabrics cannot respond well with high TDS water. For this purpose, you should try diluting 1 part of the discharge in 2 parts of the freshwater. You may also use it to wash away carpets, rugs, and curtains that aren’t too fragile.
