I run my wastewater into my garden. I don't think the TDS of the wastewater is high enough to have a negative impact. In addition, the salt is leached by other watering and rain. My Hydrangea loves it. I have always had a hard time keeping one alinve here because it needs so much water. I ran an extra 25 ft. of tubing to that part of the garden and it keeps the area around the Hydrangea saturated.
