In Jordan, in a backdrop of water scarcity and high demographic growth, recycling wastewater is of capital importance to supply populations and irrigate crops.
In 2003, Jordan's minister for water and irrigation decided to modernise and update the old saturated, pond stabilisation system in As Samra, focusing on four priorities:
Located in a desert area a few km from the capital city Amman, the new As Samra plant must treat the wastewater of 2.2 million inhabitants and meet the needs of the region's agricultural and industrial users.
SUEZ has been operating in the country since 1997. In 2003 it was awarded a Build, Operate and Transfer contract for plant extension (phase 1), in consortium with MORGANTI (CCC Group). This 25-year contract is similar to a public-private partnership. During phase 1, the capacity of the plant was extended to 267,000 m3 /day. Construction was completed in 2008.
In 2012, Jordan's government renewed its trust in us with a contract to expand the plant and carry out operations until 2037 (phase 2). The plant’s capacity was extended from 267,000 to 364,000 m3 /day (+37%), making it the largest and most modern wastewater treatment plant in the country. The biosolids line was expanded by 80%. For each phase, a portion of the CAPEX is funded by a US grant, to maintain tariffs at an affordable level.
SUEZ combined several solutions for this plant, in order to optimise:
Enhance wastewater treatment capacity
The As Samra plant was designed to treat 100 million m3 of water annually, with appropriate and efficient systems:
In 2012, Jordan's government once again demonstrated its trust in us to expand the plant and operate it until 2037. The capacity of the plant was therefore extended from 267,000 to 365,000 m3 /day, making it the largest and most modern wastewater treatment plant in the country.
Generate its own power
The new plant produces almost all of its operating power, through:
Recover residual sludge
Drying the residual sludge on site means it can be transformed into granule form and used as fuel or fertiliser.
This project received a WEX Global Award for innovative financing and a World Finance Infrastructure Award in 2013.
The As Amra wastewater plant is operated almost entirely by local employees, with a high level of local knowledge and skills development, recognised by successful ISO certifications (9001, 14001, 18001, 50001, 55001).
