As a building owner or manager in New York City, it is important to understand the critical elements of water treatment for cooling towers. When it comes to building size and population, cooling towers offer the most efficient means of providing air conditioning in the city. New York is different compared to other states in that it is the only state with legislation on how to maintain cooling towers so that they are safe to operate around people. Building owners and managers must follow a specific protocol or procedure for water treatment.
In order to understand how to properly manage and maintain your cooling tower, it’s important to be familiar with how cooling towers work, what the water treatment needs are as far as protection from legionella, corrosion, and scale, and finally what the regular process is for upkeeping your tower.
Cooling Tower Use & Challenges
Cooling towers are vital components in most New York City buildings. They play a crucial role in maintaining optimal indoor temperatures and ensuring the efficient operation of various systems. By utilizing evaporative cooling, these towers dissipate excess heat generated by air conditioning systems and industrial processes.
Through a combination of water circulation, heat transfer, and evaporation, cooling towers help regulate the temperature within buildings, contributing to energy conservation and the overall comfort of residents and occupants.
Maintaining cooling tower water quality does present challenges due to potential issues including scaling, corrosion, and biological growth. These problems can decrease tower efficiency, increase maintenance needs, and pose health risks.
In New York City, ensuring compliance with environmental regulations and addressing potential issues such as fouling or sediment buildup is mandatory. Local Law 77 requires the inspection and registration of cooling towers to prevent the spread of Legionella bacteria.

Need For Cooling Tower Water Treatment
Understanding the challenges and potential problems associated with untreated water in cooling towers is necessary in order to appreciate why the treatment process is essential. The most common issues are corrosion, scale formation, and biological growth.
Corrosion in cooling towers can be caused by various factors, including the presence of dissolved oxygen, improper pH levels, and high levels of dissolved solids. Water treatment plays a vital role in mitigating corrosion by implementing chemical inhibitors to create a protective film on metal surfaces.
This prevents direct contact with corrosive agents. Additionally, maintaining appropriate pH levels through chemical adjustment helps create a less corrosive environment. Regular monitoring and control of water chemistry parameters, along with proper filtration and periodic cleaning, also contribute to reducing corrosion and extending the lifespan of system components.
Scale formation in cooling towers is primarily caused by the precipitation and accumulation of minerals, such as calcium, magnesium, and silica, that are present in the water supply. These minerals can precipitate out of the water and deposit onto surfaces, leading to the formation of scale.
Water treatment addresses this issue through various methods. One common approach is the use of scale inhibitors, which are chemical additives that can prevent the formation of scale by altering the crystal structure of minerals or inhibiting their growth. Additionally, water treatment may involve processes such as softening or demineralization to reduce the concentration of scaling minerals.
Biological growth in cooling towers is primarily caused by the presence of microorganisms, such as bacteria, algae, and fungi, in the water. Factors like warm temperatures, nutrients in the water, and the availability of sunlight promote the growth and proliferation of these organisms.
Water treatment helps mitigate biological growth through the use of biocides. Chlorine or bromine-based chemicals are commonly used to inhibit the growth of microorganisms. Additionally, non-chemical methods like UV sterilization or advanced filtration systems may be employed to further prevent microbial colonization.
In the context of New York City, Local Law 77 was implemented to address the risk of Legionnaires’ disease associated with cooling towers. The law requires regular inspection, registration, and the implementation of a water treatment program for cooling towers to prevent the growth and transmission of Legionella bacteria.
Compliance with water treatment protocols, including the proper use of biocides and routine monitoring, has become a requirement to ensure the safety and public health of residents and occupants in NYC buildings.
