A proposal for a new work item within the scope of an existing committee shall be submitted to thesecretariat of that committee with a copy to the Central Secretariat and, in the case of a
subcommittee, a copy to the secretariat of the parent technical committee. Proposals not within thescope of an existing committee shall be submitted to the secretariat of the ISO TechnicalManagement Board.
The proposer of a new work item may be a member body of ISO, the secretariat itself, anothertechnical committee or subcommittee, an organization in liaison, the Technical Management Board or
one of the advisory groups, or the Secretary-General.
The proposal will be circulated to the P-members of the technical committee or subcommittee forvoting, and to the O-members for information.
IMPORTANT NOTE: Proposals without adequate justification risk rejection or referral tooriginator.
Guidelines for proposing and justifying a new work item are contained in Annex C of the ISO/IEC
Directives, Part 1.
☒ The proposer has considered the guidance given in the Annex C during the preparation of the

Scope of the proposed deliverable.

The international standard will define requirements and test methods to ensure safety,
performance, and sustainability of community-scale resource-oriented fecal sludge
treatment units that serve approximately 1,000 to 100,000 people. The standard will apply
to treatment units that (a) primarily treat human excreta, (b) are able to operate in nonsewered and off-grid environments, and (c) are prefabricated. The standard will not apply
to sanitation treatment units requiring sewer infrastructure or electric grid access.
Additionally, treatment units to which the standard will apply exhibit resource recovery
capability (e.g., energy, drinking water, fertilizer) and are capable of being energy
independent or energy net positive.
The standard is intended to ensure the general performance, safety, and sustainability ofsuch units. The standard will exclude installation, selection, and maintenance andoperation of such units.

Purpose and justification of the proposal*

According to the World Health Organization (WHO), an estimated 2.3 billion people have no accessto safe, clean toilets and 1 billion are forced to defecate in the open. The devastating consequencesof these practices include an estimated 1 million preventable deaths per year, primarily fromdysentery-like diarrheal diseases. 1
Where there is provision of sanitation facilities, often the fecal sludge is unsafely disposed – sludge
directly to the environment; the bulk of this untreated fecal sludge is from on-site systems that are
not being emptied and left to overflow or if emptied improperly disposed due to economics oftransporting to distant centralized treatment facilities, nor recovery of beneficial treatment
product. Essentially, current fecal sludge management approaches are often failing with direct
impact on human health and safety due to environmental degradation as a result of unsafe disposal.
The development of a standard leading to certified effective, efficient community scaled resource
oriented sanitation treatment systems would be a material change to the service chain by having
smaller, more localized treatment systems making it easier (logistically and economically) to serve
poor communities.
While PC 305 aims to reinvent the toilet and promote an international performance standard on a
consumer level house-hold scale, another critical step will be to reinvent fecal sludge treatment
through the deployment of a stand-alone, industrial scale, community scaled resource oriented
sanitation treatment system. In order to realize the full impact of these technologies and deploy
them safely at a large scale, relevant safety and performance guidelines are needed for thecommercial systems as well.
Some national standards and other guidelines have been developed that apply to certain aspects ofthe community scaled resource oriented sanitation treatment system, or to separate but related
technology. However, no international standard has been found to contain the commonly accepted
criteria by which to measure the performance of the community scaled resource oriented sanitation
treatment systems in total. Such an international standard would enhance efforts to widely
manufacture, market and deploy the technology where it is needed most.
There are three ISO committees that currently involved in similar areas of standards development:
ISO TC 224, Service activities relating to drinking water systems and wastewater systems, ISO TC
275, Sludge recovery, recycling, treatment and disposal and ISO TC 282, Water reuse. This proposed
work is out of scope for these committees at this time.
The scope of ISO TC 224 focuses on management systems and service quality while this project will
focus on the qualification of the design of the system and the performance treatment andprocessing technologies. The goal of the project is to define the technical parameters, target values
and thresholds for this technology.
ISO TC 282 deals with water reuse, and water suitable for reuse is one beneficial product createdby this technology. However, the work of TC 282 does not address treatment technology or theother beneficial products – biosolids, biogas or integrated conversion of product to electricity –created by the technology of this proposed project.
The work of TC 275 is complementary to the work of this project. TC 275 focuses on sludge
characterization to facilitate informed decisions on the selection of treatment technologies anddisposal. This project focuses on new and novel approaches for resource recovery oriented fecal
sludge treatment and will have a strong focus on design, safety and performance qualification of
resource recovery oriented treatment technologies.

Version 01/2016

Based on these considerations, and the fact that no ISO Committee currently exists to address thetechnology, ANSI and the Bill & Melinda Gates Foundation took the first step by proposing an
International Workshop Agreement (IWA), currently in progress. Once developed, it is ANSI’s intent
that the IWA may serve as the basis for a new international standard developed by the proposed
ISO project committee. Currently, partners and grantees of the Foundation consist of stakeholders
from around the globe, including developing countries, participate in the 3-workshop IWA and ANSI
intends to make a specific effort to continue to encourage participation from developing countries
in the ISO activity.
