Overview

The oSIST prEN ISO 8099:2015 standard, titled Small craft - Toilet waste retention systems (ISO/DIS 8099:2015), was developed by the International Organization for Standardization (ISO) in collaboration with CEN to define requirements for sewage retention systems on small craft up to 24 meters in length. Although the original project was cancelled and replaced by oSIST prEN ISO 8099:2015-1, this standard provides valuable guidance on the design, construction, and installation of temporary sewage retention systems specifically for marine sanitation devices on small boats. The scope does not cover sewage treatment systems but focuses on containment and safe management of sewage waste.

Key Topics

• Retention System Design
  The standard mandates that all toilets on small craft must connect solely to a holding tank retention system to securely collect and contain sewage.

• Material and Construction Requirements
  Components such as hoses, piping, and tanks must be robust under marine conditions, tolerating temperatures from -40°C to +60°C and preventing vapor and liquid leaks inside the craft.

• Plumbing and Fittings
  Critical elements, including hoses, piping, and seacock fittings, must follow specific dimensional and pressure resistance criteria to ensure reliability and prevent blockages or leaks. Through-hull fittings require valves that can be secured closed.

• Vent Systems
  Effective venting must be provided to discharge gases externally, even when the craft is heeled up to 20°, and must include clog-resistant components with adequate flow area for tanks of varying capacities.

• Holding Tanks
  Both permanently installed and portable holding tanks are covered with requirements for secure fastening, accessibility, content level indicators, tank wall integrity, and fittings accessibility. This ensures easy inspection, maintenance, and safe waste containment.

• Operational Conditions
  The retention system must function properly even when the craft is heeled (leaning) up to 30-45° or trimmed (tilted forward or backward) up to 10°, preventing back siphoning and sewage escape.

• Pump-out Fitting and Identification
  Standardized discharge connections compatible with shore reception facilities are specified to facilitate sewage pump-out. Proper identification markings and information for owners are essential for safe, user-friendly operation and compliance.

• Electrical Integration
  While primarily mechanical, the standard touches on electrical system requirements consistent with ISO 10133 and ISO 13297, for integration with small craft electrical installations.

Applications

• Small Craft Manufacturers
  Manufacturers designing sailboats, motorboats, and other vessels under 24 meters use oSIST prEN ISO 8099:2015 guidelines to install compliant sewage holding and retention systems that meet safety, environmental, and operational standards.

• Marine Equipment Installers
  Installation professionals ensure sewage plumbing, holding tanks, and venting systems conform to specifications for durability, leak prevention, and ease of maintenance.

• Boat Owners and Operators
  Owners gain assurance that installed retention systems properly contain and vent sewage under typical operating conditions, minimizing odor, spill risks, and environmental impact.

• Regulatory Authorities and Marine Inspectors
  This standard supports regulatory oversight by establishing objective criteria for sewage retention system safety and functionality on small craft.

Related Standards

• ISO 228-1: Pipe Threads
  Specifies dimensions and tolerances for threaded pipe joints used in marine plumbing systems.

• ISO 9093-1: Seacocks and Through-Hull Fittings
  Covers metallic seacock fittings essential for secure discharge pathways in marine sewage systems.

• ISO 10133 and ISO 13297: Electrical Systems
  Define extra-low-voltage DC and AC electrical installations respectively, ensuring electrical components of retention systems meet safety requirements.

• oSIST prEN ISO 8099:2015-1: Replacement Standard
  Provides updated guidance following cancellation of oSIST prEN ISO 8099:2015, reflecting current best practices in retention systems for small craft.

---

Implementing the specifications from oSIST prEN ISO 8099:2015 ensures small craft are equipped with reliable, safe, and environmentally responsible toilet waste retention systems. Adhering to such internationally recognized standards supports regulatory compliance, enhances user safety, and reduces marine pollution risks.
