Chapter 2: Minimum Standards in Water Supply, Sanitation ...

1 Chapter 2:MinimumStandards in Water Supply, Sanitationand HygienePromotionHow to use this Chapter This Chapter is divided into six main sections: hygiene Promotion, Water supply , Excreta Disposal, Vector Control, Solid WasteManagement and Drainage. Each contains the following: the Minimum Standards :these are qualitative in nature and specifythe Minimum levels to be attained in the provision of Water andsanitation responses; key indicators:these are signals that show whether the standardhas been attained. They provide a way of measuring andcommunicating the impact,or result,of programmes as well as theprocess, or methods, used. The indicators may be qualitative orquantitative; guidance notes:these include specific points to consider whenapplying the standard and indicators in different situations,guidance on tackling practical difficulties, and advice on may also include critical issues relating to the standardor indicators, and describe dilemmas, controversies or gaps incurrent appendices include a select list of references, which point tosources of information on both general issues and specific technicalissues relating to this San53 Contents hygiene Excreta Control.

The Humanitarian Charter is concerned withthe most basic requirements for sustaining the lives and dignity ofthose affected by calamity or conflict, as reflected in the body ofinternational human rights, humanitarian and refugee law.

4 Everyone has the right to Water . This right is recognised ininternational legal instruments and provides for sufficient, safe,acceptable, physically accessible and affordable Water for personal anddomestic uses. An adequate amount of safe Water is necessary toprevent death from dehydration, to reduce the risk of Water -relateddisease and to provide for consumption, cooking, and personal anddomestic hygienic requirements. The right to Water is inextricably related to other human rights,including the right to health, the right to housing and the right toadequate food. As such, it is part of the guarantees essential for humansurvival. States and non-state actors have responsibilities in fulfillingthe right to Water .

5 In times of armed conflict, for example, it isprohibited to attack, destroy, remove or render useless drinking waterinstallations or irrigation Minimum Standards in this Chapter are not a full expression of theRight to Water . However, the Sphere Standards reflect the core contentof the Right to Water and contribute to the progressive realisation ofthis right Charter and Minimum StandardsThe importance of Water supply , Sanitation andhygiene promotion in emergenciesWater and Sanitation are critical determinants for survival in the initialstages of a disaster. People affected by disasters are generally muchmore susceptible to illness and death from disease, which are related toa large extent to inadequate Sanitation , inadequate Water supplies andpoor hygiene .

6 The most significant of these diseases are diarrhoealdiseases and infectious diseases transmitted by the faeco-oral route (seeAppendix 4). Other Water - and Sanitation -related diseases includethose carried by vectors associated with solid waste and main objective of Water supply and Sanitation programmes indisasters is to reduce the transmission of faeco-oral diseases andexposure to disease-bearing vectors through the promotion of goodhygiene practices, the provision of safe drinking Water and thereduction of environmental health risks and by establishing theconditions that allow people to live with good health, dignity, comfortand security. The term Sanitation , throughout Sphere, refers toexcreta disposal, vector control, solid waste disposal and providing sufficient Water and Sanitation facilities will not, onits own, ensure their optimal use or impact on public health.

7 In orderto achieve the maximum benefit from a response, it is imperative toensure that disaster-affected people have the necessary information,knowledge and understanding to prevent Water - and Sanitation -relateddisease, and to mobilise their involvement in the design andmaintenance of those facilities. In most disaster situations the responsibility for collecting Water fallsto women and children. When using communal Water and sanitationfacilities, for example in refugee or displaced situations, women andadolescent girls can be vulnerable to sexual violence or exploitation. Inorder to minimise these risks, and to ensure a better quality ofresponse, it is important to encourage women s participation in watersupply and Sanitation programmes wherever possible.

8 An equitableparticipation of women and men in planning, decision-making andlocal management will help to ensure that the entire affectedpopulation has safe and easy access to Water supply and sanitationservices, and that services are equitable and Standards in Water supply , Sanitation and hygiene PromotionHP/Wat SanLinks to other chaptersMany of the Standards in the other sector chapters are relevant to thischapter. Progress in achieving Standards in one area often influences andeven determines progress in other areas. For a response to be effective,close coordination and collaboration are required with other with local authorities and other responding agencies is alsonecessary to ensure that needs are met, that efforts are not duplicated,and that the quality of Water and Sanitation responses is instance, where nutritional Standards have not been met, theurgency to improve the standard of Water and Sanitation increases, aspeople s vulnerability to disease will have significantly increased.

9 Thesame applies to populations where HIV/AIDS prevalence is high orwhere there is a large proportion of older or disabled people. Prioritiesshould be decided on the basis of sound information shared betweensectors as the situation evolves. Reference to specific Standards orguidance notes in other technical chapters is made where to the Standards common to all sectorsThe process by which an intervention is developed and implemented iscritical to its effectiveness. This Chapter should be utilised inconjunction with the Standards common to all sectors, which coverparticipation, initial assessment, response, targeting, monitoring,evaluation, aid worker competencies and responsibilities, and thesupervision, management and support of personnel (see Chapter 1,page 21).

10 In particular, in any response the participation of disaster-affected people including the vulnerable groups outlined below should be maximised to ensure its appropriateness and quality. Vulnerabilities and capacitiesof disaster-affected populationsThe groups most frequently at risk in emergencies are women,children, older people, disabled people and people living withHIV/AIDS (PLWH/A). In certain contexts, people may also becomevulnerable by reason of ethnic origin, religious or political affiliation,58 Humanitarian Charter and Minimum Standardsor displacement. This is not an exhaustive list, but it includes thosemost frequently identified. Specific vulnerabilities influence people sability to cope and survive in a disaster, and those most at risk shouldbe identified in each the handbook, the term vulnerable groups refers to allthese groups.
