Water softener - how much wastewater does it dump down the drain ?

Hello,
I intend to purchase a water softener for my home. One that "adds" to the existing installation. Everything would be without a problem, but I have read on the net that during the operation of such a device there is waste water, which must be given to the sewage system.
The place where he plans to install such a softener is, unfortunately, quite far from the nearest sewage pipe. He does not want to demolish and renovate half the house on the occasion of the installation of the softener.
And here the question arises (I looked through quite a few sites and forums and found nothing on this subject): how much impurity is expelled by such a device ???? I guess that it depends on the amount of water that will flow through it, the hardness of the water, but still I do not know how much it will be.
I'm asking because I'm thinking about installing some +- 20 liter waste tank, which I would empty from time to time...

Please suggest whether this is a good idea and how much waste water, more or less, will appear during the operation of the softener.
My water consumption per month is about 10-12 m3.

Greetings.

The softener requires plumbing to carry out regeneration of the ion exchange resin with brine solution. In the process, it flushes the bed against the normal flow to scarify and clean it, and flushes it with brine. All the water used during the process goes into the sewer system. Manufacturers should state the amount of water used per regeneration cycle and the amount of water that can be softened after one cycle. Check in the data of the softener you want to buy. Typically it is a few hundred liters per cycle, the larger the softener the more.

Thank you for your reply

I am thinking of something of this type:

In the description it says the number of liters to regenerate 200 l.

As much as that?

How often in my case will such regeneration be performed? (I will remind that the water consumption at my place is 10-12 m3)
I see that these things will not be cheap to operate....

In the auction description you have the amount of water the softener is able to treat between regenerations, it depends on the hardness of the water as it is at your place. You can measure the hardness with a test, even such an aquarium test, or try to find out at your local water company.

This would agree, because you need about 3 times the amount of brine to the volume of the cationite deposit and the same amount to flush with pure water. Although the amount of water for brine depends on the concentration of brine obtained, and it will not always be the maximum in such machines.
Inquire with the manufacturer whether it is possible to program this purifier for manual regeneration, i.e. on task, that is, when you want, and not when the machine deems it necessary.
This, in turn, would in your case make it uneconomical to buy an automated conditioner, which is much more expensive just because of the control computer.
I used to have my own small column with cationite and another for brine made of sewage pipe 120 or 150mm with an inspection trojnik, through which I poured salt.
This was connected by a system of ball valves so that I manually regenerated the cationite deposit, and used about 1m3 of water softened below 1 degree of German hardness and replenished hard water to 10 degrees. to change the water in several aquariums of 180-350l each.
With such a manual treatment of the deposit, you can for this time connect a thick hose to the nearest sewer and roll it up after treating the deposit.
If the surface of the cationite is "worn out" and you need to regenerate again, you will know it during washing, because the soap foams much less.
Of course, to do it all manually, you would have to understand all the details of the operation of cationite and its regeneration, but if the machine does it for you after manual pressing the switch, it will be ok.

I, before my first softener purchase, came across an interesting website about zmiękczaczach zmiekczaczewody.com.pl Check it out maybe it will help you .

You must have a drain, because the home softener overflows 200-300l liters for regeneration depending on the size of the bed.
In my case, with hardness of 18 degrees German, regeneration is repeated every 4m3 water intake.
The costs are small ( about 500l per month plus about 2-3 kg of salt) in relation to the benefits.
