ISO PC 318

What is ISO PC 318?

ISO Project Committee 318 (ISO PC 318), Community scale resource-oriented sanitation treatment systems, is currently developing a voluntary, international product standard. The standard will focus on fecal sludge treatment through the development of sanitation treatment units. These sanitation treatment units will treat waste at a community level even in places where there are no suitable wastewater treatment systems in place.

Sanitation value chain.

The new ISO project committee (ISO PC 318) was formed in April 2018 to bring together international experts to build on information and expertise gathered to develop an international workshop agreement, IWA 28, a major step to help realize the potential of community scale sanitation treatment technologies. The committee currently has 29 participating member countries and 16 observing member countries. The American National Standards Institute (ANSI), the U.S. member body to ISO serves as the twinned secretariat alongside Association Sénégalaise de Normalisation (ASN) , Senegal’s member body to ISO.

Scope of ISO PC 318

The focus of this technical document on non-sewered faecal sludge treatment units is represented by the red box along the sanitation value chain in Figure 1, indicating the treatment components of fecal sludge management. The purpose of this document is to specify performance and safety requirements of community-scaled resource-oriented fecal sludge treatment units serving approximately 1 000 to 100 000 people, ensuring technical robustness and safety in terms of human health and the environment. This document aims to facilitate the commercialization and transfer of these treatment units into the market.

This document compliments ISO 30500, Non-sewered sanitation systems – Prefabricated integrated treatment units – General safety and performance requirements for design and testing, developed by ISO PC 305, Sustainable non-sewered sanitation systems.

ANSI – as the secretariat to ISO PC 318 – is calling on global participants to join ISO PC 318. All interested stakeholders can contact their national standards body or Sally Seitz, PC 318 secretary, ANSI. Contact Sally Seitz.
