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 15749-4 was prepared by Technical Committee ISO/TC 8, Ships and marine techology, 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

4 Disposal
4.1 General

For the disposal of wastewater from sanitary drainage systems, a distinction is made between:

 overboard wastewater disposal via a wastewater storage unit and disposal pipes overboard or to a

connection from where it is transferred to an external disposal point (see 4.2);

NOTE Wastewater storage units according to this part of ISO 15749 are collector tanks, sewage treatment plants, or

vacuum generating units for the respective facilities
 discharge directly overboard via gravity drain lines (see 4.4).
4.2 Disposal points with storage units
4.2.1 Disposal piping system

Disposal lines from storage units to disposal points shall be designed as pressure lines; for details see

Figure 1.

Figure 1 shows a simplified example of routing of disposal lines within the framework of a sanitary drainage

system, leading from the storage unit (e.g. collector tank, sewage treatment plant) to the disposal points.

4.2.2 Discharge over the side
4.2.2.1 Closing devices

As closing devices, fittings shall be installed in the disposal piping section between the wastewater pump and

the wastewater outlet (piping section Z); see Figure 2. Closing devices shall be certified by the classification

societies.

The arrangement, number, and type of fittings depends on the vertical distance from the summer

loadline/bulkhead deck of the lowest opening (drain).

NOTE Such openings (drains) also include, for example, emergency overflows of sewage treatment plants or

openings for dosing of chemicals.
4.2.2.2 Drains

4.2.2.2.1 In the disposal pipe, a screw-down non-return valve shall be installed at the shell. If it is not

possible to place the shutoff fitting directly at the shell, the pipe from the shell to the shutoff fitting has to be

designed thick-walled, see 6.1 and Figure 3.
