Pollution Prevention Guidelines for the Operation of Cruise Ships under Canadian Jurisdiction (2013) 17.1 Fresh water management techniques .. reclamation and
reuse of water for non-potable purposes, should include: • the use of technical water (for example: air conditioning
condensate) where possible; • the use of water recovery systems (for example: filtering
and reuse of laundry water – last rinse use for first wash); • reclamation and reuse as technical water (flushing toilets,
laundry, open deck washing) of properly treated and filtered wastewaters;
