Is it safe to discharge saline/brackish water into septic tanks?

With the start of winter being soon, I'm wondering if I can discharge my used saline into the septic tank. If I can should I do smaller water changes daily rather than a ?/40/50% wc on a less frequent basis.

I'm not sure on the size of my ST but it's rated for a 6 bed house, local bye-laws mandate it to be emptied every 2 years.

When I kept fish before I just used to discharge inot the local sewage system and allow the dilution effect of being in a conurbation to alloy my conscience.

I always dump my water outside. Im in a rural area with a septic tank and well water. Whether it would be a problem pouring water down the drain causes negative effects I am not certian but to me it seemed more logical to pour it out in the grass as it could benefit from the dissolved nutrients in the water.

we can get to -40 F/C in the winter..I really don't want or need large glassy areas outside my house for 3 or so months....IYKWIM..

eta..summer not as much as a problem I can use the water to keep my drives clear of weeds..
