Ways to Counter Water Scarcity in Jordan

Water scarcity is a reality in Jordan, as the country is counted among the world’s most arid countries. The situation has been exacerbated by the large-scale influx of refugees due to the Syrian crisis. The current per capita water supply in Jordan is 200m3 per year which is almost one-third of the global average. To make matters worse, it is projected that per capita water availability will decline to measly 90m3 by the year 2025. Thus, it is of paramount importance to augment water supply in addition to sustainable use of available water resources.

How to Augment Water Supply in Jordan?

There are couple of options to increase alternative water supply sources in Jordan – desalination of seawater and recycling of wastewater. Desalination can provide a safe drinking water to areas facing severe water scarcity, and may also help in resolving the conflict between urban and agricultural water requirement needs by providing a new independent water source.

The other way to counter water scarcity in Jordan is by recycling and reuse of municipal wastewater which is an attractive method in terms of water savings. Infact, the reuse of the treated wastewater in Jordan has reached one of the highest levels in the world. The treated wastewater flow in the country is returned to the Search River and the King Talal dam, where it is mixed with the surface flow and used in the pressurized irrigation distribution system in the Jordan valley.

Another cheap and natural option for wastewater reuse is the construction of wetlands, and surface water reservoirs, which are water storage facilities that are able to collect and hold rain water for later use during dry seasons for irrigation or even for fish farming purposes. To prevent water loss by evaporation, reservoirs should be covered in a specific way to allow air to enter but with minimum evaporation rate. Another option is to install floating solar panels above the reservoir which will not only reduce the evaporation rate but also produce clean energy.

However, technology-based solutions are also raising several environmental and health concerns. Seawater desalination and wastewater treatment are like large-scale industrial projects which are capital-intensive, energy-intensive and generate waste in one form or the other. The desalination process may be detrimental to the marine ecological system as it increases the salinity of seawater.

Similarly, irrigation using recycled municipal wastewater is causing public health concerns. For example, directly consumed vegetables and fruits are excluded from allowable crops. Further studies should be conducted so as to address health issues that might arise from municipal wastewater usage. Effluent irrigation standards should be broadened to encompass a wider range of pathogens, and appropriate public health guidelines need to be established for wastewater irrigation taking into consideration the elimination of steroids.

New Trends to Lookout For

New intervention is needed to satisfy local irrigation demands; irrigation water for agriculture makes up the largest part of total average water used, which accounted for 64% during 2010. The main period of water stress is during summer due to high irrigation demand, and there is therefore a conflict arising between the supply of water for urban use and agricultural consumption.

There has to be a proper combination between improvement of irrigation methods and selection of crop types. Application of updated water techniques, such as micro-sprinkling, drip irrigation and nocturnal, can reduce water loss and improve irrigation efficiency. Infrastructure improvement is also necessary to improving efficiency and reducing water loss.

Spray irrigation has higher efficiency than traditional methods.

Crop substitution is another interesting method to increase water efficiency by growing new crop types that tolerate saline, brackish, and low irrigation requirements. Such approach is not only economically viable, but also is socially beneficial and viable to mankind in an arid ecosystem. Mulching system is also highly recommended to reduce evaporative loss of soil moisture and improve microbial activities and nutrient availability. Farmers should use organic manure, instead of chemical fertilizers, to increase quality of water and reduce risk of groundwater contamination and agricultural run-offs.

The industrial sector uses about 5 percent of water resources in Jordan, while releasing harmful substances to the environment (including water). Industries have to put together a water management plan to reduce water intake and control water pollution. For instance, the establishment of a local wastewater treatment plant within a hotel for irrigation purposes is a good solution. Traditional solutions, like Qanats, Mawasi and fog harvesting, can also be a good tool in fighting water scarcity in arid areas.

    Considering the topography of Jordan map, what is observed is that, excepting for dead sea, Jordan's water resources are in deficit compared to the land area & growing urbanization & irrigation coverage areas. So the situation is about renewing the water resources for Jordan, whether new resources / storage strategies / recycled. The following technology feasibility can be enhanced.

    New water resources : By international agreements, sea water from Mediterranean sea, should be brought down via gravity to Jordan. If it calls for pumping, we can set up our Mass water Ram pumps, which can dispatch sea water to ant high altitude destinations without the need for direct electricity / fuel power. Either Dead sea / artificial storage reservoir can be constructed at strategic locations covering the entire country.. There is also one more facility of collection of fresh rain water during rainy seasons form open sea coastal areas & the same can be dispatched to Jordan by the above said Ram Pumps.

    Developing of storage reservoirs : Lake / Pond / Dam system of water storage leads to over flow drain off to sea, in case of surplus in flow. The best practice could be construction of artificial walled storage reservoirs above surface reservoirs like lakes / ponds / rivers or even sea water storage from Mediterranean sea for that matter. This system storage helps to improve capacity storage as well as prevent overflow drain outs.
