Full title and description

Ships and marine technology — Drainage systems on ships and marine structures — Part 4: Sanitary drainage, sewage disposal pipes. This part of ISO 15749 gives requirements and recommendations for the design and selection of sewage disposal piping used in sanitary drainage systems on ships and marine structures.

Abstract

ISO 15749-4:2004 specifies principles for the design, materials, installation and testing of sewage disposal pipes within the overall sanitary drainage framework for ships and marine structures. It is intended to be used together with the other parts of ISO 15749 for planning and basic requirements of sanitary drainage systems.

Scope

ISO 15749-4:2004 applies to the design of sewage disposal pipes forming part of sanitary drainage systems on ships and marine structures. It covers requirements for pipe materials, dimensions, installation practice, connections and testing relevant to sewage (blackwater) disposal lines, and is to be used in conjunction with ISO 15749-1 (planning and basic requirements). The part does not address piping carrying oily or chemically contaminated wastewater intended to form flammable mixtures.

Key topics and requirements

• Definition and classification of sewage disposal piping for sanitary systems on ships.
• Material and component selection criteria suitable for marine service (resistance to corrosion, biofouling and mechanical loads).
• Nominal bore sizing, connection details and layout principles for continuous sewage discharge lines.
• Installation practices, supports, routing and segregation from other systems to avoid contamination and hazards.
• Testing, inspection and commissioning requirements for installed sewage disposal piping.
• Compatibility with the series’ planning guidance given in ISO 15749-1 and with gravity and vacuum piping guidance in ISO 15749-2 and ISO 15749-3.

Typical use and users

Designers and naval architects specifying shipboard sanitary systems, marine engineers responsible for piping installation and commissioning, shipbuilders and shipyards, regulatory and class surveyors, and maintenance teams on ships and offshore structures use this part to ensure safe, hygienic and environmentally compliant sewage piping installations.

Related standards

ISO 15749 is a multi-part series addressing sanitary drainage on ships. Relevant companion parts include ISO 15749-1 (sanitary drainage-system design), ISO 15749-2 (drain piping for gravity systems) and ISO 15749-3 (drain piping for vacuum systems); drainage of weather decks, cargo holds and swimming pools is addressed in ISO 15749-5. These related parts provide planning, system-type and application-specific guidance that complements Part 4.

FAQ

Q: What is this standard?

A: ISO 15749-4:2004 is the part of the ISO 15749 series that covers sanitary sewage disposal piping for ships and marine structures, specifying design, material, installation and testing requirements for such piping.

Q: What does it cover?

A: It covers sewage (blackwater) disposal pipes within shipboard sanitary drainage systems — including material selection, nominal bore and connection details, routing and support, and testing/inspection of installed piping. It is intended to be used with the other parts of ISO 15749.

Q: Who typically uses it?

A: Naval architects, ship and offshore engineers, shipbuilders, classification societies and maintenance personnel use the standard when designing, installing and certifying sanitary sewage piping on vessels and marine installations.

Q: Is it current or superseded?

A: The ISO record shows ISO 15749-4:2004 as the published edition (2004) and indicates the publication has been subject to periodic review; the ISO catalogue entry lists the standard as confirmed (reviewed and confirmed) in recent systematic reviews. Users should verify the current status with national or ISO catalogues before procurement.

Q: Is it part of a series?

A: Yes — ISO 15749 is a series of standards on drainage systems on ships and marine structures. Part 1 covers overall sanitary drainage-system design; Parts 2 and 3 cover gravity and vacuum drain piping respectively; Part 5 covers drainage of weather decks, cargo holds and swimming pools.

Q: What are the key keywords?

A: Sanitary drainage, sewage disposal pipes, ship plumbing, marine piping systems, ISO 15749, gravity drainage, vacuum drainage, installation and testing.
