Disinfection & Chlorination Services
Eliminate biological contamination and maintain safe water quality in potable, cooling, and process water systems with proven disinfection programs and AWWA-compliant procedures.
Disinfection Programs That Protect People and Systems
Biological contamination in water systems — from Legionella and Pseudomonas to general heterotrophic bacteria and biofilm — poses serious risks to building occupants and accelerates system corrosion. Effective disinfection requires more than a one-time shock treatment; it demands a systematic approach that addresses the root causes of microbial growth and maintains ongoing control.
RW Water Services provides comprehensive disinfection and chlorination services for potable water, cooling water, and process water systems. From emergency hyperchlorination following a positive Legionella test to routine biocide programs for cooling towers and closed loops, our programs are designed to eliminate contamination, restore safe water quality, and prevent recurrence.
All disinfection procedures follow applicable AWWA standards, state health department guidelines, and facility-specific Water Management Plan protocols. We provide complete documentation of all disinfection activities for regulatory compliance and insurance purposes.
Comprehensive Disinfection Capabilities
Hyperchlorination
High-dose chlorination programs for emergency disinfection of potable water systems, cooling towers, and domestic hot water systems following contamination events or positive Legionella results.
Ongoing Biocide Programs
Scheduled oxidizing and non-oxidizing biocide programs for cooling towers, closed loops, and process water systems to maintain continuous microbiological control.
Thermal Disinfection
Coordinated thermal flush programs for domestic hot water systems — raising system temperatures to eliminate Legionella and other thermophilic bacteria from storage tanks and distribution piping.
Chlorine Dioxide Treatment
Chlorine dioxide generation and application for systems where traditional chlorine is ineffective or undesirable — particularly effective against biofilm in complex distribution systems.
Residual Monitoring
Ongoing chlorine residual testing and documentation to verify disinfectant levels are maintained throughout the distribution system, with corrective action protocols when residuals fall below target.
Post-Disinfection Verification
Water sampling and laboratory analysis following disinfection events to confirm biological clearance before returning systems to service.
Disinfection Services We Provide
Emergency Hyperchlorination
Rapid-response hyperchlorination for potable water and cooling systems following positive Legionella cultures, contamination events, or regulatory orders.
New System Disinfection
AWWA-compliant disinfection of new and repaired potable water mains, storage tanks, and distribution systems prior to placing into service.
Cooling Tower Disinfection
Seasonal startup disinfection, shock treatments, and ongoing biocide programs for cooling towers in compliance with ASHRAE 188 and local regulations including NYC Local Law 77.
Domestic Hot Water Disinfection
Thermal and chemical disinfection programs for domestic hot water storage and distribution systems, targeting Legionella and other waterborne pathogens.
Closed Loop Disinfection
Biocide programs for chilled water, heating hot water, and condenser water closed loops to prevent biofilm formation and microbiologically influenced corrosion.
Process Water Disinfection
Custom disinfection programs for process water applications in food and beverage, pharmaceutical, and manufacturing facilities where water quality directly impacts product safety.
