Abstract In the 13th
World Water Congress, IDRC’s presentation on greywater use in MENA is thought to be a synthesis of lessons
learned from IDRC supported initiatives on greywater in the region, including also recommendations for future
research needs. Therefore, the presentation cannot strictly follow the suggested structure (i.e introduction, objective,
methods, results and conclusion).
Water is scarce in the MENA region, therefore the general need for new
water saving technologies must be acknowledged. Economic cost-benefit analyses have been conducted for a
number of IDRC-supported and greywater-related projects. Cost-benefit ratios of 1 to 5, and 1 to 4 have been
reported for a number of projects, but these appear too optimistic. The most robust of all of the economic reports is
a cost-benefit of 1 to 2.75 in a research project that was conducted in Jordan. This translated to about 6 Jordan
Dinar per month on an average salary of 300 Jordan Dinar. What this suggests is that any strategy to further develop
greywater treatment and use will need to develop messages that include not only economic but also environmental
and social messages. This also signifies the continued need to see greywater use as a way to alleviate water stress
and not only as a poverty alleviation strategy.
The Aqaba Declaration on Greywater Use in the Middle East
and North Africa (February 15th, 2007) that emerged from an IDRC-supported activity (Greywater Stock Meeting
in Aqaba) should be promoted as the benchmark of future work on greywater in the region. In this Declaration, it
was agreed that: 1) greywater provides an important potential to alleviate water scarcity in dry countries and it
should be seen as a water source as opposed to a waste product, 2) greywater use must be promoted in a way that
minimizes health and environmental risks while generating economic benefits, 3) greywater use is considered to have
potential as a water demand management option for the MENA region and there is a need to respond to existing
demand for non-conventional sources of water by promoting the widespread adoption of greywater use, 4) in order
to raise the profile of greywater and promote its widespread use there is a need to work closely with all relevant
stakeholders and to focus on clear and straightforward messages, and 5) any technological intervention should be
cost effective while meeting accepted standards.
