Sanitation in Emergency
1. Excreta disposal
2. Solid waste management
3. Waste water management (drainage)

How do we do excreta disposal in a emergency?
Rapid assessment & planning design
Implementation:
1st phase – Immediate action
In-depth assessment & planning design
Implementation:
2nd phase – medium term action
Monitoring

Sphere Standards and Indicators
SPHERE standard 1: access to and numbers of toilets
People have sufficient numbers of toilets, sufficiently close to their dwellings to allow them rapid, safe and acceptable access at all
times of the day and night.

Sphere Standards and Indicators
SPHERE standard 2: design and construction
People have access to toilets which are designed, constructed and maintained in such a way as to be comfortable, hygienic and safe to
use.

Selection Criteria
Number of people using latrine and location of peopleCommunal or familyElderly/disabled populationDesign life: - will population move?SpaceComfort and community desiresTradition of latrine use in community PrivacyUse of water/reuse of faeces – availability of water?Anal cleansing material (amount of water used)MenstruationAvailability of local materials and tools

Selection Criteria (cont.)
Pit sizeV = (NxSxD) + 0.5 m of free space x A
N = number of users; S = Sludge accumulation (m3/person/year); D= design life (years)
A= pit-base area (m2)
GroundwaterNot all designs suitable for high groundwaterUsually 99% of pathogens destroyed within 2m of unlined pit in unconsolidated soils if above water tableIf in saturated zone then contamination spread is HORIZONTAL (usually) up to 15m
Soil conditionsSoil stabilityInfluence if a pit or soak pit is possible to excavateWatch for effects throughout the seasonsInfiltration rate
International Federationof Red Cross and Red Crescent Societies
11
Selection Criteria (cont.)
Siting Communal latrines good distance (30m) away from dwellings and down wind if possible Family latrines near to dwelling (5m) Away from water sources (see groundwater) Avoid depressions, water courses that might run with water DISCUSS with community Space for additional latrines

Latrine components – basics
•Privacy and dignity•Roof is essential in areas with high rainfall•Door / spiral-shaped entrance•< 1 m2 is recommended•Frame: timber, PVC pipe, •Fitted with plastic sheeting, local materials•User’s involvement in design
Superstructure
•Support weight of a person•Easy to clean•Prefabricated or manufactured locally•Concrete, wood, ferrocement or plastic
Slab
Pit
•1 m across and 3 m deep (minimum 0.9 m diameter)•Best shape: circular•The top 0.5 m of a pit should be always lined (but depend of soil)•Different pit lining material: locally available

Communal or Family?
Family facilities:
Usually designed and built by the users (with or without designs, tools and materials provided by others).
They may be used by several families. The latrine belongs to the family / ies.
Communal facilities:
Managed by the community as a shared resource (market, school, etc.).
The facility belong to the community.

Operation and Maintenance
Cleaning: Supervision + Equipment + TrainingCommunal latrines: Need for employing some members to clean and maintainOwnership: Involving population in design, siting, construction, maintenance, etc. Family latrinesCleaning materials: cleaning kit (disinfectants, mops, rags, buckets, gloves, etc)
International Federationof Red Cross and Red Crescent Societies
Handwashing Facilities
Providing handwashing facilities is easier said than done, especially in a large area. Work with your team to chose the right technology (jug, tippy tap, etc) and establish a system of keeping water available

Common Mistakes of WatSan Staff
“I think the people want…”
“In the last place I worked in we did this, so I am sure it will work here.”
“I am sure the people will clean the latrines themselves.”
