Veterans in the Water Industry: Share Your Story!
Once samples have cleared, the main can be installed. Ends must remain sealed until the main is installed.
Disinfection Procedures When Cutting Into or Repairing a Main S Trench Treatment – Treat the excavation with hypochlorite to lessen contamination. Tablets work best for slow release. S Swabbing With Hypochlorite Solution – Swab the interior of the pipe and fittings with a 1 percent hypochlorite solution before they are installed. S Flushing – Flushing is the most practical means of removing contaminants. Flush from both ends toward the work location if possible.

Flushing After Disinfection S Flush until residual is less than 1 mg/L. S Velocity is not a factor. S Dechlorination must be applied to discharged water to remove remaining chlorine.
Testing After Disinfection S After 24 hours test at least one sample for each section disinfected in a chlorinated system. S Test at least two samples for each section in a nonchlorinated system. S For long lines in excess of 2,500 feet, test samples along the line.
If Samples Fail, Disinfect Again and Repeat Samples S Flush again and resample. S If sample fails again, then dewater main and rechlorinate.
Emergency or Maintenance Disinfection S Spray with a 1 to 5 percent solution at 100 pounds per square inch (psi).
This concludes the second and final part of the disinfection series. I hope this will provide some insight into the history and methods of disinfection for all of you, especially those new operators who are preparing for advancement in their careers.

Veterans in the Water Industry: OOOO Share Your Story! OOOO
After the recent celebration of Fourth of July, which for many people was their first one since COVID-19 hit in early 2020, it’s time to think about the fourth salute to veterans in the water industry that will be highlighted in the November 2021 issue of Florida Water Resources Journal.
If you served in any branch of the United States military and are a current employee in any facet of the water industry, please share some facts about your military experience and how it has helped you in your current position.
We’re honored to highlight the brave men and women who proudly served their country, both here and abroad, and who are again serving American citizens by working as water professionals.
To tell your story, go to www.fwrj.com, download the veterans form, complete it, and return it to me as an attachment to ricklharmon@comcast.net by Sept. 24, 2021.
I look forward to receiving your form and including you in the November issue! S
