Wastewater is a big problem in our world. We use tons of water every day just to survive. In fact, most of us use more water than we should.

This is why it’s important to conserve as much water as possible. By reducing your household’s water usage, you’ll save yourself lots of money and make a difference in the environment.

In this article, I’ll explain everything you need to know about how to reduce waste water in the RO system.

How To Reduce Waste Water In RO System

How to reduce waste water in the RO system?

Use a Modern System

A modern reverse osmosis (RO) system should have a much lower water-waste ratio. You can tell if a system is performing well by checking its efficiency. Look for a system that doesn’t waste any water.

Modern RO systems are more efficient than older models. Older models were less efficient because they didn’t send wastewater back around the system multiple times. Nowadays, modern RO systems are able to recycle water multiple times before sending it down the drain.

Another reason why modern RO systems are more efficient is that they filter water through smaller pores. Smaller pores mean that there’s less space between the molecules of water, which means that the water flows faster through the membrane. This makes the process of filtering water easier and more efficient.

So if you’re looking for a modern RO system, make sure it has a low water-waste ratio.

Save Your Water

You shouldn’t use RO waste water for bathing yourself or your pets. You can still use it to clean anything that doesn’t need clean, potable water.

To extend the length of your reverse osmosis system, you can install a second pipe that connects to the main pipe. This extra pipe will deposit the wastewater into a tank outside of your kitchen. From there, you can use the water for whatever purposes you’d like.

For example, you can use the wastewater to:

  • Wash your car
  • Water your garden or plants
  • Mop your floor
  • Wash your patio furniture
  • Rinse paintbrushes
  • Clean off muddy shoes
  • Use the wastewater to fill your swimming pool

Recycling Discharged Water

Another way to recycle discharged water in your RO system is to funnel it to any fixture where you don’t need pure water. You can do this by installing a drain valve near the outlet of your RO unit. Then, connect the drain line to a sink or tub faucet.

This method works well if you only need to reuse the water once or twice before disposing of it. However, if you plan to reuse the water multiple times, you should consider investing in a separate tank for storing the recycled water.

A third option is to install a drain valve near the output of your RO system. Connect the drain line to a shower head or bathtub spout. This method is ideal if you plan to reuse your discharged water multiple times.

However, be aware that reverse osmosis discharged water contains a high concentration of impurities. Therefore, it may not be suitable for drinking or cooking purposes.

Check Your Water Pressure

Low water pressures may result in excessive amounts of reverse osmosis discharge water. You should check your water pressure regularly to prevent any problems.

To check your water pressure, turn off the main water supply to your house and run cold tap water through the faucet until the flow stops. Then measure the water pressure using a standard kitchen or bathroom scale. Ideally, you should aim for a reading between 35 and 40 pounds per square inch (PSI), although anything lower than 30 PSI may indicate a problem.

If your water pressure is low, you might have a leaky pipe somewhere in your plumbing system. Or it could be caused by a clogged filter or sediment buildup in your pipes. Either way, you should contact your local water authority to determine whether there are any issues at their facility.

Perform Regular Maintenance

Reverse osmosis filters are not “set it and forget it” products. You need to perform regular maintenance on them to keep them working properly. And if you don’t, they won’t work as well.

Most good reverse osmosis systems include multiple stages of filtration. Each stage has its own type of filter for catching certain types of particles. These filters can last anywhere between two and fifteen years. But if you don’t regularly clean them out, they may clog up and stop filtering effectively.

So before you start using your new reverse osmosis system, get familiar with how it works. Find out where the filters are located and how to access them. Also, find out how to remove the filters and clean them out.

Once you know how to maintain your reverse osmosis system properly, you’ll be able to avoid costly repairs down the road.


The first step towards reducing your water usage is to install an efficient reverse osmosis (RO) system. This will allow you to save a lot of water while still getting clean drinking water.

However, you need to be careful when installing such systems because they require a lot of maintenance. So, make sure you hire a professional who knows what he/she is doing.
