Cooling Tower Maintenance
Our expert custom Cooling Tower Maintenance Program & Plan development affords you peace of mind by enabling you to fulfill the specific requirements mandated by New York City.
It’s the Law!
In response to the recent outbreak of Legionella, New York City set forth specific requirements for the operation and maintenance of cooling towers.
NYC Cooling Tower Inspections and Services provides a highly experienced Certified Water Technologist (accredited through the Association of Water Technologies) to develop a custom cooling tower maintenance program and plan as outlined below:
- Mandatory tasks by both qualified persons and responsible persons must be performed in order to comply with the cooling tower’s maintenance plan, required by law and developed by the property’s qualified person in line with Chapter 8 requirements.
- The plan must be kept on-site and must be accessible if requested by an inspector. §8-03(a)-(d) lists specifics that must be included in the plan, and cites that owners must follow the most stringent requirements if there are conflicts between Chapter 8, SSC 4, the Administrative Code, or the manufacturer’s instructions.
- There are also standards to follow when a cooling tower ceases operation or goes back into operation after a certain length of time.
Specifics Regarding Monitoring Tasks and Timing:
- A responsible person must visually inspect/monitor the cooling tower at least weekly, a qualified person is required to perform compliance inspections (process outlined in the law) at least once every 90 days.
- By law, the cooling tower must be cleaned and disinfected whenever routine monitoring indicates a need, but no less than twice annually.
- Per the law, water in a cooling tower system must be treated at least once a day when the system is in operation, and such treatment may be automated (unless the maintenance plan specifically outlines how manual or less frequent biocide additions will effectively control legionella growth).
- Once per week, while the tower is in operation, a bacteriological indicator (dip-slide) must be obtained to estimate bacteria content of the cooling tower water system and then compared to a microbial comparison chart. All bacteria results must be addressed in accordance to the law.
If Taking Manual Water Quality Measurements:
Water quality parameters must be measured at least 3 times each week, provided that no more than two days pass without such measurement when the cooling tower system is operating.
If There Are Continuous, Automated, and/or Remote Water Quality Measurements:
The management program and plan must show how effective measurements of system process controls are being monitored. Our high-tech water treatment feed equipment continuously monitors levels remotely and alarms notify our water treatment experts of any issues that arise.
Results must be properly recorded and made available to the department upon request.
- Owners must keep and store records onsite for at least 3 years.
- In addition to completing Annual Certification with the DOB, owners must post the DOB-assigned Cooling Tower Registration number on the device.
