Reclaimed Water and Plants
- Reclaimed water and plants
- Plants with no tolerance
- Plants whose leaves may be damaged if exposed to overhead irrigation
- Plants that can tolerate reclaimed water containing less than 400 PPM chloride salts
- Plants that are completely tolerant of reclaimed water

data provided by Dr. John Parnell of the City of St. Petersburg.
Pasco County's education program was developed to teach residents about reclaimed water. For more information on Pasco's Purple Rain, please call (727) 847-8145 or e-mail www.pascocountyfl.net.
|Take care not to overwater your plants just because you're using reclaimed water. Too much water can be detrimental to plant health. Apply a maximum of 1 inch at each watering and water less often in winter than in summer.|
|Reclaimed water has higher levels
of chloride salts than drinkable water. Chloride
concentrations in Pasco County's reclaimed water fall in the 100 to
400 ppm range. On rare occasions, reclaimed water from the
West Reclaimed Water Loop will rise above 400 ppm. Most
landscape plants will tolerate reclaimed water with chloride concentrations of
400 ppm or lower. Some will tolerate even higher levels.
A few plants are totally intolerant of chloride. Others will
show leaf burn if the foliage is exposed to overhead
irrigation with reclaimed water containing more than 100 ppm
When there is no rainfall to dilute the reclaimed water entering the system in a particular area, chloride levels can rise higher than normal.
Below are some of the plants included in studies conducted by the City of St. Petersburg in the late 1980s, grouped by their chloride tolerance.
