Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 15749-1 was prepared by Technical Committee ISO/TC 8, Ships and marine technology, Subcommittee
SC 3, Piping and machinery.
ISO 15749 consists of the following parts, under the general title Ships and marine technology — Drainage
systems on ships and marine structures:
— Part 1: Sanitary drainage-system design
— Part 2: Sanitary drainage, drain piping for gravity systems
— Part 3: Sanitary drainage, drain piping for vacuum systems
— Part 4: Sanitary drainage, sewage disposal pipes
— Part 5: Drainage of decks, cargo spaces and swimming pools

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
wastewater
off-running water which has undergone change due to use, as for instance sewage (contaminated water),
water from precipitation, seawater and condensation water that has reached the drain lines.
NOTE 1 With this type of wastewater, a distinction is made between grey water and sewage.
NOTE 2 For the classification of wastewater in accordance with origin, see Table 1 in Clause 4.
3.2
grey water
wastewater to be disposed of, excluding sewage
3.3
sewage
wastewater from water closets, urinals and bidets, including additives; medical areas (pharmacy, hospital,
etc.) and from washing basins in those areas, bath tubs and water discharges; spaces housing living animals
and other types of wastewater, if mixed with contaminated water already mentioned.
NOTE The definition of 'sewage' is in accordance with the definition of Annex IV of MARPOL 73/78.
3.4
pipes in sanitary drainage systems
