What is in recycled water?
The process to create recycled water begins at the end of a wastewater treatment plant. Think of its source as water suitable for the receiving waterway. Depending on how it’s treated – recycled water will be dosed with some Sodium Hypochlorite (NaCl) [I’ll call it Chlorine] – used as a disinfectant.
The recycled water permit issued by the state dictates how much residual Chlorine is in the water – Title 22 is that permit if you want some bedtime reading – http://www.cdph.ca.gov/certlic/drinkingwater/Documents/Lawbook/RWregulations-01-2009.pdf.
At every recycled water treatment facility, they are required continually test their recycled water Chlorine residual levels 24 hours a day and store the results.
