Full title and description

BS EN ISO 8099-2:2020 — Small craft — Waste systems — Part 2: Sewage treatment systems. This publication is the British (BS) adoption of the international standard ISO 8099-2:2020 and specifies requirements for the design, construction and installation of sewage treatment systems intended for use on small craft.

Abstract

This standard specifies requirements for the design, construction and installation of sewage treatment systems on small craft. It explicitly excludes requirements for waste retention systems and does not set technical discharge limits for treatment units (those are subject to international and national regulations).

Scope

ISO 8099-2:2020 applies to sewage treatment systems fitted on small craft and sets out requirements for their design, construction and installation. The standard does not cover temporary waste retention systems nor systems intended to prevent accidental discharge of other pollutants (for example oil or fuel). It also does not define numerical discharge limits for treatment units, since those are covered by other international or national regulations.

Key topics and requirements

• Design requirements for sewage treatment systems intended for small craft (materials, functional layout and interfaces).
• Construction and manufacturing considerations to ensure suitability for marine service and safe operation on small craft.
• Installation requirements and guidance for correct integration into small-craft waste systems and plumbing.
• Exclusions and limitations — does not replace regulatory discharge limits or requirements for retention systems and pollutant containment.
• Conformity and verification considerations aimed at manufacturers, installers and surveyors (functional performance and installation checks; see national/regulatory requirements for effluent limits).

These topics are drawn from the ISO 8099-2 technical summary and national/adoption notes.

Typical use and users

Primary users include small-craft designers and builders, manufacturers of marine sewage treatment units, installers and system integrators, surveyors and flag/port-state authorities responsible for equipment acceptance and installation checks. The standard is used to define minimum technical and installation expectations for sewage treatment systems where applicable.

Related standards

ISO 8099 is a multi-part series. The principal related document is ISO 8099-1:2018 — Small craft — Waste systems — Part 1: Waste water retention — which covers temporary retention systems (retention tanks) and complements the Part 2 treatment requirements. National and regional adoptions (EN ISO / BS EN ISO) are also relevant for regulatory alignment.

FAQ

Q: What is this standard?

A: It is BS EN ISO 8099-2:2020 (British adoption of ISO 8099-2:2020), titled "Small craft — Waste systems — Part 2: Sewage treatment systems", specifying technical requirements for sewage treatment systems on small craft.

Q: What does it cover?

A: It covers the design, construction and installation requirements for sewage treatment systems on small craft and states what it does not cover (temporary retention systems, accidental pollutant discharge prevention, and numeric discharge limits which are set by other regulations).

Q: Who typically uses it?

A: Manufacturers of sewage treatment units, small-craft designers and builders, installers, surveyors, and regulatory or flag/port authorities use the standard to assess and ensure correct design and installation of onboard sewage treatment systems.

Q: Is it current or superseded?

A: ISO 8099-2:2020 is published (ISO edition December 2020) and the BS adoption was published in April 2021; the ISO record shows the standard under the normal periodic review cycle. Users should check national catalogues or the ISO database for any updates after publication.

Q: Is it part of a series?

A: Yes — it is Part 2 of the ISO 8099 series. Part 1 (ISO 8099-1:2018) addresses waste-water retention systems and complements Part 2 (treatment systems). National and EN adoptions exist for both parts.

Q: What are the key keywords?

A: Small craft; waste systems; sewage treatment; marine sanitation; installation requirements; design and construction; ISO 8099-2; BS EN ISO 8099-2.
