Improperly managed Potable water is an established route for infectious disease transmission onboard!

You may now think yourself being on the safe side as onboard your vessel only bottled water is used for drinking but what about the water used for personal hygiene? What about the water used for food preparation, the water used to clean the surfaces you come in contact daily? All of it needs to be of such high quality that transmission of diseases is prevented and it needs to be available in such quantities that all types of useage can be covered. 

The "Guide to Ship Sanitation" issued by the WHO mentions the following hazardous elements roughly divided into two groups:  

  •  Microbes that cause infectious disease or food poisoning, such as bacteria,
     viruses and parasites
  •  Organic and inorganic substances that may cause health hazards, such as
     substances that can cause acute poisoning, substances that accumulate in the
     human organisms causing health hazards, carcinogenic compounds and/or
     allergenic substances

International regulations regarding the Potable Water Quality Monitoring and Control were driven by the World Health Organization (WHO) via its International Health Regulations (IHR). Soon enough adapted for on-board potable water, as part of the overall Ship Sanitation Certificate. Current International Health Regulations (2005) and ILO 178 (2009) apply to all countries/flag states that have ratified to them. The ILO Maritime Labour Convention, (MLC 2006) does apply to all seagoing vessels. Monitoring and control compliance procedures are laid out in the Guide for Ship Sanitation detailing:  

  •  the systems that require monitoring,  
  •  the method and frequency of monitoring  
  •  the record keeping requirements

The draft guidelines were created in close collaboration with the International Labour Organisation (ILO) and the International Maritime Organisation (IMO). Alongside SOLAS, MARPOL and the STCW Convention the MLC 2006 has been introduced as the fourth pillar of the regulatory regime of IMO. It will require an MLC 2006 certificate. Simple regular assessment and testing of the potable water system for microbiological activity, biocide (disinfection control) and implementing a correct control scheme (i.e. temperature monitoring), will ultimately reduce the risk of a disease and save lives.

According to ILO MLC (2006), IHR (2005) and ILO 178 (2009) a qualified person is required onboard the vessel or rig to perform the test.CMT does provide a complete training for Marine Portable Water to ensure understanding the legislation and performing all test according the legislations. At the end of the training each attendee will get a certificate proving the respective qualification.
