MARINE BLACK AND GREY WATER SERVICES 

An essential component of your marine vessel preventative maintenance schedule. Clearvac provides specialist black and grey water services for Super yachts, commercial vessels, cruise ships, and offshore platforms globally.

 

Black Water Pipe Descaling

Plumbing networks that carry black wastewater are prone to mineral buildup, and over time, these buildups can lead to blockages. Clearvac uses a unique method of pipe descaling that effectively removes all hard-scale deposits, restoring all plumbing networks to fully functional systems. This service does not impact business operations or sailing schedules; the vacuum system remains fully operational throughout the service period without disrupting passengers or crew.

There is no requirement to remove any toilets or pipework, except to carry out before-and-after inspections with the vessel’s chief engineer to gather information for our comprehensive service report.

Clearvac’s black water service ensures unrestricted flow through all pipework and eliminates all contaminants.
