Water scarcity is one of the most pressing problems in Jordan. The gap between supply and demand is getting bigger due to population growth and climate change, which is estimated up to 250MCM/year. Jordan's water strategy stresses the importance of using non-traditional water resources to cope with this shortage, such as rainwater harvesting and greywater reuse. Greywater is a kind of wastewater which comes out of sewers, sinks and laundry. There are a wide range of technologies for greywater treatment in the market, however they are quite expensive and a bit complicated, making their adoption by the local communities very low.

The Drawer Compacted Filter is a new design for grey wastewater treatment in which the sand filter is broken down into several layers approximately 10cm high, each of which is placed in a movable drawer that is stacked vertically, with each drawer separated by 6-8cm. This treatment unit overcomes the problems commonly found in traditional filter designs, such as clogging, high footprint and other. This filter has been tested and piloted in Jordan for the previous 5 years and has been found efficient in removing contaminants from grey water. The filter now is very close to market.
