SWG backflush question

[Amail]

When I backflush, I run a flat hose out to the front lawn to discharge the water. If I were to go to a SWG system would I still be able to discharge onto the lawn, or would the salt content wreck the grass?

My backflush pvc pipe leads directly into a dry creek. The dry creek is full of green living plants of unknown parentage. The salt hasn't slowed them down a bit. <shrug>

What type of grass is it? How much rainfall do you get in a year? The effects of discharging pool water and increasing the sodicity of the soil depends a lot on how much rainfall you expect to get as well as the soil type (loamy, clay/loam, sandy, etc). Every plant is different but many types of plants can handle excess sodium and calcium as long as the soil pH isn't too high.

See some of this literature

4. SODIC SOILS AND THEIR MANAGEMENT

We're in Southern California, which is slowly coming out of a long drought. We've got Bermuda grass that looks fantastic when everything's well watered. Currently it's mostly dead, but I'm more concerned about the effects when it's growing well.

Thanks for the links, I'll check those out.
