About WaterAid . . .
WaterAid is an International Organisation
WaterAid operates in 26 countries with the mission for improving access to safe water, hygiene and sanitation in poor communities
In Bangladesh, we reached over 2 million water, 6 million sanitation and 7 million hygiene beneficiaries till the last year
Area coverage:Rural: 50 upazilas under 20
districts Urban: more than 300 slums in
58 wards under 3 City Corporations [Dhaka, Chittagong & Khulna]
Small Town: 3 Municipalities [Paikgacha, Fulbaria, Shakhipur]
We stepped in the CHT since 1999

We stepped in the CHT since 1999
Current level of operation . . .
At a glance: CHT
Hilly terrain
1/10th of total land area
Population: 1.16 million
Hardcore poor: 30%
11 ethnic communities
Vibrant Socio-political environment
Remoteness- depriving from fundamental needs
Sanitation Situation in the CHT
About 75% population use some form of latrine while 25% defecate at open places (ref. CHT Baseline Census by WaterAid, PSU & Unnayan Samannay, 2010)
Of them who are using latrines, only 29% are hygienic
Sanitation facilities:
Mostly pit latrines with/ without lid
Pit latrines with/ without water seal
Water Situation in the CHT
Safe water coverage: 59%
Natural water sources: Springs (jhiris) and Streams (charas)
Average daily consumption: 5-10 litres/person (ref: Counting the Hills, 2007)
Avg. water collection time and distance: 2hr/day; 3 km
Spend about 1/3rd of monthly income for treatment
Water technologies in the CHT
Shallow / Deep-set Hand Tubewell
Ringwell
Infiltration Gallery [IFG]
Gravity Flow System (GFS)
Distribution of households using different water sources (59% hhs having access to safewater)
Challenges in water technologies
High investment costO&M difficulties (requires technical skill and repairing cost)But the most importantly drying up of ‘sources’
Why? Why?
WaterAid commissioned a Study to investigate underlying causes of spring flow deterioration jointly with CEGIS and BCAS in 2007
Image analyses
Climatic and hydro-geological data analyses
Perceptions of local inhabitants and indigenous knowledge
Analyses of climatic data
Decreasing trend in Annual Rainfall (1961-2003)
Increasing trend of Evaporation (1989-92)
Increasing trend of Sunshine hours (1987-2002)
Few key findings…Few key findings…
Few key findings…Few key findings…Analyses of Images of entire CHT (1989-2003)
53% loss of dense forest (170,000 ha)
23% increase of agricultural land and homestead
1989 2003
Khagrachari district
97% loss of dense forest
65% increase of agricultural land

Causes of Spring flow deterioration
Loss of conducive environment at sources due to deforestation
Due to plantation of exogenous species (like Shegoon, rubber, tobacco etc.) soil becomes exposed and loss of vegetation in the catchment area does not allow to percolate rainwater into the ground to fed the spring during dry season. Landslides are increasing as a consequence.
Change in landuse pattern
Causes of spring flow deterioration
Jhum cultivation cycles becoming too close
Infrastructures constructed without considering of the impacts on overall environment
Major recommendations of the study were:• Social aforestation• Spring management• EIA for infrastructure development • ‘Aquifer Recharge’ for ensuring
drinking water in the long run
Let’s look forward …
A holistic planning and adaptation of water resource management is needed by relevant sector actors A separate Sector Development Plan (SDP) for the CHT is underway; integration of compatible strategies is essential The emerging concern –protection natural springs is essential which requires support from beyond WSS sector and political will
