Headhunter, specialists in plumbing and sanitation for the luxury yacht and commercial marine industries, has received eight certificates of approval for new models in its Tidal Wave HMX sewage treatment plants, the first to be approved according to the new, more stringent performance standard set by the United Nations International Maritime Organisation (IMO).
The Environmental Protection Committee (MEPC) adopted the new resolution MEPC 159(55) in 2006, though the implementation date was set for 1 January, 2010. In response, the United States Coast Guard issued Navigation and Vessel Inspection Circular Number (NVIC)1-09 , which laid the procedural framework for the Marine Safety Centre to evaluate manufacturers of sewage treatment systems ccording to the new standards.
