Urban American Completes Legionella Remediation Efforts

WESTMONT, Ill., Sept. 29, 2026 /CourierPR/ -- Urban American, a leading sponsor, owner, and operator of multifamily housing, has successfully completed remediation measures in compliance with the New York City Department of Health and Mental Hygiene (DOHMH) Commissioner's Order dated January 6, 2026, relating to Legionella bacteria in the building water system at 3333 Broadway, the largest residential structure in Manhattan. The order, originally issued on December 29, 2025, and updated on January 6, 2026, required Urban American to address the presence of Legionella in the building's water system.

The DOHMH Order mandated that Urban American implement a multi-barrier water management system from LiquiTech, a global leader in smart water management for buildings. This remediation program, which included the deployment of LiquiTech's copper-silver ionization system, supplemented by patented sediment filtration and smart water sensors, was designed to ensure DOHMH compliance and protect the long-term wellness and satisfaction of residents.

Urban American, founded in 1997, has a proven track record of acquiring, owning, and improving more than 22,000 apartment units across New York, New Jersey, Colorado, and Texas. The company has invested over $500 million in capital improvements and more than $50 million in energy efficiency and carbon reduction projects. Urban American's fully integrated platform spans acquisition, development, and management, combining centralized back-office services and asset management with on-site property operations.

The remediation measures were implemented to address the presence of Legionella bacteria in the building's water system, which had been confirmed through baseline sampling conducted at 3333 Broadway. Urban American's commitment to finding a solution that would not only ensure DOHMH compliance but also support the long-term health and satisfaction of residents led to the selection of LiquiTech's multi-barrier system. This system, which uses copper and silver ions to deliver ongoing bacterial kill in building water systems, was complemented by sediment filtration and smart water sensors, providing real-time visibility into key aspects of the water system.

In the wake of these improvements, sampling conducted in August 2026 by an independent certified industrial hygienist detected no Legionella at the locations tested at 3333 Broadway, at the reporting limit of the analytical method used. This achievement marks a significant milestone in Urban American's ongoing efforts to provide a safe and healthy living environment for its residents.

LiquiTech, a company that has provided water treatment solutions to healthcare, hospitality, multi-family, education, commercial, and industrial customers for over three decades, was selected by Urban American due to its sustainable technologies designed to improve water quality, control the growth of waterborne pathogens, and minimize the risk of infections without generating harmful byproducts. The company's multi-barrier system, which is specifically designed to improve the efficiency and longevity of water-bearing equipment by reducing the corrosion and buildup associated with high sediment levels and oxidant-based chemicals, was chosen for its efficacy and safety.

For Urban American, reducing Legionella positivity and ensuring that the building water service would not be interrupted, the system would not employ potentially toxic chemicals, and it would not corrode pipes and equipment, were key criteria. The company's decision to partner with LiquiTech underscores its commitment to putting residents first by addressing the root cause of the problem.

In addition to reducing Legionella positivity, the multi-barrier solution implemented by Urban American also provided real-time visibility into key aspects of the water system, ensuring ongoing monitoring and maintenance. This approach aligns with Urban American's fully integrated platform, which combines centralized back-office services and asset management with on-site property operations, allowing for a comprehensive and effective management of the building's water system.

The successful remediation of the building's water system at 3333 Broadway is a testament to Urban American's ongoing commitment to providing a safe and healthy living environment for its residents. This achievement also highlights the effectiveness of LiquiTech's multi-barrier system in addressing the challenges posed by Legionella bacteria in building water systems. Urban American's proactive approach to water management and its partnership with LiquiTech demonstrate the importance of addressing waterborne pathogens to ensure the safety and well-being of building occupants.
