Chlorinations & Disinfections
New Building and Piping Disinfection
Before a new building’s water system goes online, the piping needs to be properly disinfected. Watertech of America performs new building and water main disinfections in compliance with AWWA Standard C651-14 for all types of commercial, industrial, and healthcare facilities.
This is not optional work. Newly installed piping can harbor bacteria, sediment, and construction debris that compromise water quality from day one. A professional disinfection ensures your system starts clean and meets regulatory standards before occupants move in.
One-Time Hyperchlorinations
When a facility receives a positive Legionella test result or is responding to a case investigation, a one-time hyperchlorination is often the first corrective action required. Watertech performs emergency hyperchlorinations to bring systems back into safe operating condition.
We also perform one-time sanitizations for specific equipment, including RO skids and other process water systems that require periodic disinfection.
Cooling Tower Cleanings
Cooling towers accumulate biological growth, scale, and debris that reduce efficiency and increase health risk. Watertech performs cooling tower cleanings and disinfections as part of routine maintenance or as an emergency response to elevated bacteria counts.
Contractor Services
If you are a mechanical contractor working on new construction, Watertech is your partner for new build hyperchlorination. We handle the disinfection and the required verification testing so you can close out that portion of the project with confidence. Our team works on your timeline to keep the job moving.
When to Call Watertech
- Your facility has received a positive Legionella or waterborne pathogen result and needs immediate disinfection
- You are a contractor completing a new building and need water main disinfection per AWWA C651-14
- Your cooling tower needsa professional cleaning and disinfection
- Equipment such as RO systems or process water lines requires sanitization
- You are responding to a case investigation and need rapid corrective action
We also perform the verification testing required after any disinfection to confirm the system is safe for use. For ongoing water quality programs, visit our Validation Testing page.
Considerations When Selecting Biocides
| Type of Biocide | Advantages | Disadvantages | Common Applications |
| Chlorine | • Low cost • Readily available • Effective in open systems • Kills planktonic biofilm (Free floating) |
• Can form NTM by-products in hot water recirculation systems. • Corrosive to metals |
• Cooling towers • Secondary disinfection • Produce washing • Breweries |
| Stabilized Bromine | • More stable than chlorine in warmer temperatures • More effective at maintaining the correct pH • Less odor • Less of a skin irritant |
• More costly than chlorine • Takes a little longer to activate than chlorine • Low pH |
• Cooling towers • Spas and hot tubs |
| Chlorine Dioxide | • Quick killing • Effectively penetrates biofilm |
• Generator may be required • Difficult to maintain residual in hot water systems • Generates chlorite as a disinfection by-product in domestic water application |
• Cooling towers • Secondary disinfection • Produce washing • Breweries |
| Monochloramine | • Most effective against biofilm • Least corrosive to metals • Highest stability |
• Generator Required • Slower kill rate than chlorine/chlorine dioxide |
• Secondary disinfection • Cooling tower |
| Peracetic Acid | • Low cost • Effective at removing/ killing microbes on surface |
• Can be highly corrosive | • CIP cleaning • Produce washing • Cooling towers • Breweries |
| Hydrogen Peroxide | • Low cost • Aggressive oxidizer |
• Regulated by Homeland Security • Greater safety concerns |
• Cooling towers • Wastewater |
