Service activities relating to drinking water supply, wastewater and stormwater systems — Water and wastewater services for temporary settlements for displaced persons
This document provides guidelines for alternative water services (AWS) and alternative wastewater services (AWWS) to temporary settlements for displaced persons e.g. refugee/internally displaced persons (IDP) camps, for drinking, sanitation and hygiene purposes. It addresses AWS and AWWS principles and methods, operational planning and implementation. This document provides guidelines for drinking water supply to temporary settlements, and the disposal of wastewater, by implementation of different methods; it does not deal with the ways of using water inside the temporary settlements. This document deals with drinking water quantity but does not provide methods for quality testing. Water quality test methods are included in the scope of ISO TC 147. The document does make recommendations regarding public safety with respect to the location of distribution and collection points. On-site treatments are not discussed in this document but, depending on circumstances, they can be suitable. In such case, helpful technical guidelines are provided in the bibliography of this document. This document complements ISO 24527, whose scope excludes drinking water supplied to temporary settlements. It also complements other ISO TC 224's documents such as ISO 24518 and ISO/TS 24520. This document is intended to be used by the responsible body for the provision of the water service. It can be used by interested parties such as water utilities, governments and governmental organizations, security bodies, international refugee agencies, related NGOs and relevant industry stakeholders.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.

Introduction
Natural disasters, climate change and wars resulting in the mass migration of populations fleeing
their homes to temporary settlements such as refugee/internally displaced persons (IDP) camps has
become a reality in many parts of the world. Temporary settlements are planned or spontaneous places
where refugees or IDPs can reside and benefit from welfare provision, safety and protection, and other
assistance from host governments and humanitarian actors. Reliable and good quality water supply
for purposes such as drinking, sanitation, hygiene, e.g., WASH (water, sanitation and hygiene) is critical
for the survival of the
