Waterworks offers microbiological analysis of potable water quality and other water parameters followed by recommendations for rectification of issues.
Water Analysis
IMO/WHO Guide to Sanitation, third edition 2011 says (excerpts):
…… Where water is used for human consumption on board ship, it has to be potable. If information is needed about the influence of the distribution system, the farthest tap should be examined to inform the assessor of the highest potential risk. This tap typically can be found at the bridge deck. Here an additional sample should be taken, referring to a suitable procedure such as ISO 19458…
Waterworks resumes a supervisory role to guide shipowners based on the findings from Water analysis.
