Like what you see? Hop on to the rest of our piece to know all the possible uses of water softener discharge. 

Let’s get started!

Why Should You Use Water Softener Discharge?

While converting hard water into soft water, water softeners produce heavy salt discharge. The discharge is known as brine. 

This discharge, if not disposed of well, can cause severe problems. For example, if brine is channeled through septic treatment plants, it kills the beneficial bacteria. 

This leads the septic system to a floundered water treatment quality. So, the brine should not be channeled through septic tanks.

Again, brine can also harm the irrigation process. In fact, it causes major groundwater pollution day by day. All these factors violate the Santa Cruz Country Code Sections 7.38,7.79. This section is about the ideal sewage disposal.

For all these factors, we need to dispose of water softener discharge in a proper way. Or, we can convert this discharge into some means of use. To know this, take a look at the following section.

Different Uses For Water Softener Discharge

We have come to know that water softener discharge can be harmful to the environment. It’s best to use this waste to regenerate into some other means of use. This can help in global environmental conservation. 

We have come up with a few uses of water softener discharge. If you are curious, take a look at the points below-

Use 1 of 5: Bacteria Elimination

If you use a water softener at home, you won’t be discharging a lot of brine. Household water softeners discharge around 50 gallons in about 70 minutes. But you can still use it. 

As said earlier, brine is rich in salt and salt kills bacteria. Use the brine to get rid of germs in different places in your house. 

For example, you can clean your kitchen corners with it. Or, you can clean your washroom to make it free from bacteria or germs. 

But whatever you do, you need a good sewage system to dispose of water softener discharge. Otherwise, you will be harming the environment without even knowing.

Use 2 of 5: Sea Fish Aquarium

There are plenty of sea fishes that you can keep in your household aquarium. Clownfish, Damselfish, Green Chromis, Clown Goby, are just some examples. People also prefer fish like Yellow Watchman Goby, Hawkfish, Cardinalfish, to keep in their aquarium.

These fishes cannot survive in freshwater. To help them, you can fill 2/3 portion of the tank with brine and 1/3 portion with fresh water. 

The water will create a suitable environment for the fish. You’ll see the result in their growth and sustainability. This also saves you the hassle of preparing saltwater for them specially.

Use 3 of 5: To Kill Weeds

Brine and vegetation are not a good combo. In fact, it’s an impossible combo. 

Well, here comes the fun part. A concentrated brine solution is the perfect weed killer. Since the discharge won’t let any plants live, why not use brine to kill weeds?

Use 4 of 5: Deicing

In winter, everything is dumped under snow. The roads can be cleared by the snow sweepers. Your yard can still be dumped in snow. For that, you can’t go out in your car. To great surprise, brine can come of great help in this situation.

In comparison to freshwater, saltwater has a lower freezing point. You can use it to deice your driveway in the winter. So, you’ll face no problem bringing out your car.

Use 5 of 5: To Keep Your Garden Free From Slugs

Often when you’re working in the garden, you might return home with a slug on your feet. This is at the same time disgusting and terrifying. 

It can get exhausting to get the slugs out of your feet. But don’t worry! It’s not as difficult as removing candle wax from the sink

To get rid of the slugs, the brine from the water softener discharge can be a solution. Slugs are extremely repulsive to salt. Because salts can dry them out and possibly kill them.  

Make a 50:50 mixture of brine and freshwater. Wash your feet with it. This is a good and painless way of removing the slugs. 

To keep your garden safe from slugs, you can also spray the solution around the garden. If you don’t have a spray bottle, it’s best to get one now. Because that way you can minimize the use of the solution. Too much of the solution can harm the soil in your garden.
