NYC Commercial Water Treatment - Protection, Compliance and Energy Efficiency Since 1982

Since 1982, Acqua Treat has kept NYC buildings safe, efficient, and compliant — handling boiler, cooling tower and closed loop water treatment, Legionella compliance, potable drinking water plumbing disinfection and glycol services for buildings across Manhattan, Brooklyn, Queens, the Bronx, and Staten Island. Family-owned. Four decades of expertise. One call covers it all.

With Local Law 159 bringing monthly Legionella testing and $1,000+ fines starting May 2026, there's never been a better time to make sure your treatment program is optimized.

  • Our technicians provide chemical treatment as needed. We also provide regular in-person testing and servicing to keep your equipment running at peak efficiency.

  • We provide the chemical treatment, injection equipment and training so that your staff can perform maintenance under our supervision.

  • We offer a range of services, equipment and chemicals for new system cleaning, chemical treatment and domestic plumbing disinfections to meet your specification requirements.

  • We provide timely water sampling and testing services, for legionella and other contaminants, to ensure you are in compliance with DOH and other state and local requirements.

  • AWWA C651-compliant disinfection of new and repaired water mains and potable water service piping. Required by the NYC Plumbing Code before new or repaired piping can be placed into service. We handle the full process — flushing, 200 ppm chlorine treatment, bacteriological testing, and documentation
