ECOLOGICAL SANITATION
  • RWANDA EXPERIENCE

2
RWANDA
WELCOME TO THE COUNTRY OF A THOUSAND HILLS
3
BACKGROUND
4
BACKGROUND (cnts )
  • Country of a thousand
  • Location East Africa
  • Size 26,338 sq km
  • Population around 10 million
  • Density 347 people/sq km
  • Capital City Kigali (around 1 million with 1670
    people/sqkm)
  • Languages Kinyarwanda, English French
  • Population growth 2.7 /yr
  • Total fertility rate 6.1 child/woman
  • Life expectancy 44-47yrs
  • Annual income/capita290 U(2000)
  • GDP/capita (263U, 01), target 400 (2010)

5
Background (cnts )
  • 88,6 depend on agriculture
  • Limited arable land (only 31 of the total area)
  • Mean size 0,6 ha, 34,4 of pop lt 50 ares
    (Gisenyi, Ruhengeri, Gikongoro, Butare)
  • 0,75 ha to provide to nutritional needs
  • Only 23.4 of arable land have less  ou or no
    erosion risk
  • 37.5 need to reshape the landscape before
    cropping
  • 39.1 have very high risk of erosion. 
  • Crops up to 80
  • No fallow
  • Marginal lands cropped
  • CGES et defend et restore soil fertility (20t de
    om/ha)

6
Background (cnts )
  • 80 of the country have access to latrines
  • 8 meet national hygienic standards
  • common sanitation facility type traditional pit
    latrines (Kigali city Rural areas) poorly
    designed, dirty not well maintained
  • Pit latrines 60
  • Flush toilet connected to septic tank 30
  • Flush toilet connected treatment plant 1
  • Direct discharge 8
  • Open defecation 1
  • Mal maintenance of latrines hygienic hazards

7
Background (ctns)
  • Negative impact on health environment due to
    mal maintenance of pit latrines (contamination
    surface groundwater, water related diseases,
    etc.)
  • Out of ten major causes of morbidity the first 5
    are water borne diseases (WBD) and 69.5 of the
    death are caused by WBD (Kabalisa, 2007).
  • The infant mortality rate of lt 5 years was
    estimated to be 192/1,000 infants in rural areas
    (due to poor sanitation cdts malnutrition)
  • Recognition of the lack of adequate sanitation
    facilities by GOR
  • Putting in place an institutional framework to
    govern water and sanitation

8
Background (cnts.)
  • Many national documents focusing on sanitation
    Vision 2020 (00), EDPRS (06), Decentralization
    policy (01), National Investment Strategy (02),
    National human settlement policy (04),
    Environment policy (04), etc.
  • Local gvt mandated for mgt of sanitation
    facilities but hampers of finance, trained staff
    and knowledge of appropriate systems, etc
    (institutional appropriateness)
  • Choices to be made regarding different
    alternatives for improved sanitation systems
    (Human health) according the available resources
    and social acceptability (affordability)
  • ECOSAN toilet based on recycling reuse of
    nutrients could be one of the options to provide
    sustainable sanitation (Environmental
    sustainability)

9
ECOSAN Experience in Rwanda
  • MDG Vision 2020,MINITERE has signed a MoU with
    Common Development Fund (2006)
  • - 100 blocks of public toilets (using UDD
    toilets) principal roads (high ways) in the whole
    country
  • - Since then, UDD toilets has been built in rural
    areas of South North provinces of Rwanda (13
    ecosan toilets)
  • 10 UDD toilets built in Rulindo through the
    funding of District, Water 4 people at Karombo
    PS,Cyinzuzi sector
  • Construction of ECOSAN toilets with 300 doors in
    hospitals, schools, police stations, etc planned
    in 2008 (FEA)

10
ECOSAN Experience in Rwanda (cnts )- South
  • The FEA (Water and sanitation Fund) has provided
    funds to build UDD toilet in Gikongoro in
  • Schools Kibeho secondary school
  • Hospitals (Nyamagabe and Kigeme hospitals)
  • Prisons
  • Schools
  • FEA provides training to the teachers and pupils
    on use of UDD before construction
  • UDD provided to the school bcoz of lack of
    adequate sanitation facilities
  • water scarcity in the region.
  • school not connected to water supply system.
  • dried faeces are used in the garden of the schools

Nyamagabe secondary school
11
ECOSAN Experience in Rwanda (cnts )- South
  • UDD toilet at Kigeme hospital
  • bad experience is seen at Kigeme hospital
  • no one in charge of maintenance and management
    of UDD toilets
  • bad smell flies were everywhere because nobody
    was in charge of the management of the system.
  • FEA put in place a management and cleaning
    personnel later
  • explanations given to every patient on how to
    use that toilet.
  • not simple job
  • technology not appropriate to the
  • Hospital UDD toilet is not self evident - --
    explanation before using a UDD toilet
  • - Need for urinal for
  • men for avoiding the mixture of urine and faeces.

12
ECOSAN Experience in Rwanda (cnts )- south
  • from the 2 experiences, it has been recognized
  • UDD toilets are appropriate in former Gikongoro
    where soils are low productive there is a
    demand for cheap fertilizer.
  • Currently, FEA is introducing the reuse of human
    excreta after drying in other schools
  • project receives other requests for UDD toilet
    from other schools.

13
ECOSAN Experience in Rwanda (cnts )- North
(Bulera)
  • 80 of the population used to defecate in the
    bush in the past, 20 use pit latrines
  • Pit latrines are not suitable bcoz the volcanic
    soil (pit with 2m).
  • big project of local gvt UNICEF funded by of
    the Netherlands gvt to reach 800 000 rural
    residents
  • Provision of improved sanitation facilities and
    safe hygiene practices

Pit latrine in Gahunga village
14
ECOSAN Experience in Rwanda (cnts )- North
(Bulera)
  • promotion of the use of UDD toilet at household
    level
  • communities are aware of the sanitized excreta
    used on Irish potatoes garden
  • UDD more appropriate to this region, materials
    locally available
  • UNICEF and local gvt provide trained people
  • community provide construction material (rocks,
    soil, wood, sand, cement)

15
ECOSAN Experience in Rwanda (cnts )- North
(Bulera)
  • public UDD toilet constructed by UNICEF Bulera
    district in the Rugarama business centre
  • Used by business menbars in the village
  • not clean even with someone to maintain it
  • people seemed not aware on how to use UDD toilet
  • Lack of urinals main cause of public UDD toilet
    bad condition
  • these are demonstration model, found in strategic
    points such as markets, governmental building
    (offices)
  • No subsidy to individual household for UDD
    toilets by UNICEF or gvt
  • Households are encouraged to build their own
    latrines.

Conclusion
  • after harvest, night soil is store in a hangar
    for decomposition for 6 months
  • It is then used as organic fertilizer
    (compost/manure)
  • It proved to be effective for tuber crops
    (potatoes carrots), less response to beans
  • small quantity harvested compared to compost or
    manure
  • to be used on kitchen garden
  • soil is still fertile, people can still crop
    without fertilizer and have good yield
  • many people are not willing to eat vegetables
    produced under such fertilizer (a woman
    influencing her children in a household)
  • High cost of UDD toilets ( 173.500 Frw bricks
    made or 310U 67.200 Frw for sheeting made or
    120 U)
  • gray water used for kitchen garden irrigation
  • urine mixed used on vegetable crops in
    replacement of nitrogen compound mineral
    fertilizers

20
Challenges of ECOSAN
  • mixing of urine with faeces, this result in odour
    and contaminates the urine with pathogensmaking
    it unsuitable for direct application in
    agriculture.
  • With UDD toilet men are required to sit to
    urinate, therefore some of men would resist to
    this requirement, hence the failure of the UDD
    toilet. This could be addressed by
  • installation of dry urinal.

21
Opportunities
  • Gaps in the sanitation service provision
  • unsuitability of current methods
  • design of pit latrines
  • demand for adequate sanitation facilities
  • condition of sanitation facilities (maintenance,
    odor)

22
Opportunities (cnts )
  • 2. Political will
  • - institutional framework for water sanitation
    different documents
  • - master plans and slums upgrading improvement
    of existing infrastructures including sanitation.
  • - water and sanitation policy attention should
    not only be made on the importance of improved
    sanitation but also on ECOSAN
  • planners and implementers would use the
    institutional framework to consider alternative
    sanitation solutions including ECOSAN.
  • IMVUGO NIYO NGIRO
  • Local gvt looking for partners in ECOSAN

Toilets ECOSAN PADBEL
Biogas PADBEL
23
Opportunities (cnts )
  • 3. Local experience
  • Campaign for appropriate technologies (biogas
    toilet, UDD toilet) pilot projects are
    conducted.
  • dvt project including ECOSAN activities (FAE,
    PADBEL, etc)
  • Many other dvpt project should include ECOSAN
  • people are becoming aware of ECOSAN
  • Lessons learned
  • Sanitation issue in the curricula is an
    opportunity to promote ECOSAN in schools
  • Good information education promote successfully
    ECOSAN
  • ECOSAN addresses the demand of fertilizer in low
    productive areas
  • ECOSAN is better solution for rocky volcanic
    areas of Rwanda than pit latrines
  • further biogas ECOSAN project could easily be
    implemented

24
Constraints
  • social-cultural beliefs
  • handling human excreta (insult)
  • Psychological problem consuming food produced
    with human excreta (30-50 in Butare)
  • shift away from the conventional pit latrine or
    flush toilet to ecosan
  • the physical appearance of faeces and urine in
    latrines is repulsive to people
  • Lack of experience and limited awareness
  • intensive education consultation on mgt before
    implementation

25
Constraints (cnts )
  • maintenance use misuse results into bad odor
    when mixed urines (upper ground level
  • Insufficient financial resources at local gvt to
    enhance the new project
  • Small quantities at household level
  • Unit cost is high for individual peasant with no
    subsidy
  • ECOSAN is still new in Rwanda, we are looking
    forward to learning from other countries'
    experiences
