Waste Water


the treated wastewater from the STPs is around
125,000m3 per day, or around 45.5 Mm3/year
The quality of the outflow is highly variable, while it is
very good quality in Hajah, it is very bad in Taiz,
depending on :



The method of treatment
The capacity of the station
The operational conditions.
Water Resources Development

Rainfall water harvesting

Improving the Irrigation efficiency

Extensive investigations for groundwater

Extensive studies for desalination

Institutional background of water
resources management:
towards entity & integrity.





Two parts of Yemen (South & North) were unified in May
1990 there were two different data systems/regimes.
In 1996 a national water resources authority (NWRA)
was established.
New Ministry for Water & Environment was established
in May 2003
Water Law was ratified and issued in August 2002
Irrigation & Dams department still with Ministry of
Agriculture & Irrigation and did not yet merged with the
new established ministry
Institutional background of water
resources management



Most of the data collection and the
information systems are still scattered among
water resources/supply & sanitation/irrigation
projects in autonomous agencies.
National Water Resources Authority is the
sole authority of water resources
management & the law enforcement in the
whole country.
There is specialized over-all agency for
statistics under the ministry of planning &
international cooperation, BUT no water Data.
Water resources strategies & policies
and legislations:
from theory to actions






Water Resources Policy and strategy(99-2000
Irrigation Water policy, (2001)
Watershed Policy, (2000)
Agricultural sector reform policy, (2000)
Urban Water Supply and Sanitation Sector
reform Policy, (1997)
wastewater reuse strategy, (under
developing)
Challenges of the water
resources:









Scarcity of water resources,
Low water supplies and use efficiencies,
Weakness enforcement of water related
laws/regulations,
Lack of proper coordination among the water related
agencies.
Minor participation of the private sector,
High population growth (3.01%)
Minor public awareness.
Lack of data/information
Lack of investment of water sector.
Existing Water Resources

Water resources statistics
problems






The data still exist among several agencies in variable
formats.
The data incomplete & with time-cut series and with
low quality.
Most of the information are estimated and predicted
for each agency purposes.
Low public investment in the water resources
management.
Lack of sufficient and efficient human resources.
Poor coordination among external donors
Recent actions




Establishing National Water Resources
Information Center (NWRIC).
Rehabilitation the existing water resources
monitoring network.
Expansion of the existing monitoring network.
Strengthening the coordination links with
water using agencies (water supply, irrigation
private sector), Statistics Agency, the
Meteorological agency and the environment
authority, as well as with the donors.
- Recommendations:







Support is still needed to steer the attempts of the
National Water Resources Authority to have country
wide organized information system.
Need to develop water resources information
guidelines.
Need to develop guidelines for predictions,
estimations and indicators in Yemen water resources
information.
Need to develop and improve data base information
system.
Need to specific and targeted training programs.
Need for donors coordination to support water
resources management programs.
Need for proper capacity building.
