Groundwater Management Challenges
Water Sector Reforms
The Way Forward

3. Introduction Tanzania
Area: 945,087 km²
Population: 37 million.
Rainfall:
500 – 2,000 mm/yr
> 70% of the area is semi arid
Uses: domestic, irrigation, hydro-electricity, livestock, industries and navigation.
9 River and Lake Basins

4. Introduction Basin Water Boards
The first was established in 1991(Pangani Basin)
Roles and Responsibilities:
Water Allocation
Water Resources monitoring and assessment
Coordinate water resources planning
Pollution control
Water use conflict management
River and Lake Basins in Tanzania

5. Groundwater Availability
Recharge: Rainfall
Major aquifers: indiscrete: (alluvial sediments , sedimentary, volcanic and Precambrian Basement rocks)
Yield of Boreholes range 10 – 800 m3/hr
Depth of boreholes: 20 – 400m.
Water quality: Generally good, with exception in some areas where fluoride contents exceed 8mg/l.
Note: So far not much exploited; mainly used for domestic water supplies
Water sold from private wells
Rundugai Springs, Kilimanjaro

6. Groundwater Management Challenges
Potential not assessed
Uncontrolled groundwater explorations and development
Fragmented data and information
Land degradation
Some aquifers in 6 Basins are transboundary
Weak legal framework
Capacity to management
Artesian well at Kahe village

7. Water Sector Reforms National Water Policy: reviewed in 2002
National Water Sector Development Strategy
had been prepared
Water Law:
under review
Water Sector Development Programme:
started implementing in 2006

8. The Way Forward
New Water law to address policy requirements to be tabled in the parliament soon;
Regulations to be prepared
Groundwater assessment task to start in 8 Basins
IWRM plan
Cooperative frameworks for transboundary water resources are being developed
Groundwater monitoring in potential identified areas
To pilot use of groundwater for irrigation

9. Thank you for listening
