Legionella Water Safety Plan
1. Public Schools personnel drain, power wash and vacuum the cooling tower annually before start-up.
2. Once the cooling tower is filled Environmental Water will shock the tower with Towerchlor based on system volume.
3. The cooling towers are on a biocide program that is administered through a water treatment controller. The treatments used are a non-oxidizing biocide (Ultrakleen #1), and an oxidizing biocide (Stabrom 909) to control bacteria levels in the cooling tower. Monthly visits with XYZ Company testing for bacteria levels are performed and adjustments are made accordingly with reports.
4. Legionella testing is being initialized this July and will be tested by XYZ Laboratory.
The new statewide regulations require registration, testing, inspection, and certification of cooling towers. View the regulations; Register your cooling tower
