Lydec (Morocco)

The re-use of wastewater for irrigation

The new wastewater treatment plant in Mediouna, which is located in the Casablanca suburbs, is a genuine technological and environmental feat. It is also the first plant in Morocco and in North Africa to use the ultra-filtration membrane process patented by SUEZ ENVIRONNEMENT. This technology offers a higher filtration quality than that of conventional membranes. As a result, the treated wastewater can be re-used for agricultural irrigation. Lydec, the Group’s Moroccan subsidiary, has also set up a system to deodorize the plant. Therefore, the new plant will improve residents’ living conditions, protect the Hassar Oued from wastewater discharges, and save water resources. Its size has been designed for 40,000 inhabitants and can be extended to 80,000, with a treatment capacity of 3,800 m³ per day. The plant was inaugurated by His Majesty Mohammed VI on April 3, 2013, in the presence of the French president François Hollande.

Remote metering arrives in Mulhouse

The City of Mulhouse’s Water Department will roll out the remote meters provided by Ondeo Systems, a subsidiary of Lyonnaise des Eaux, to its 16,000 subscribers between now and the end of 2015. This is the largest contract awarded to the Group by a district management authority, and it marks the installment of more than 1 million meters in Europe. Remote meters offer many benefits to users. The transmission of data from the meter to the Network Manager enables any unusual consumption to be identified so that users can be warned of any suspected leaks in their homes. Their bill is based on actual rather than estimated consumption. Lastly, the meter can be read automatically and remotely, eliminating the need to visit the users’ homes. For the city, remote metering is a “smart” way of monitoring the yield of the drinking water network in real-time, which includes a significant potential for savings and for protecting water resources.

Faced with the consequences of climate change, Melbourne chose sea water desalination

The city of Melbourne experienced severe water stress in the 2000s due to a doubling of its population to 4 million in 30 years and a succession of droughts that left the reservoirs of the State of Victoria, of which Melbourne is the capital, filled to just a quarter of their capacity. In 2007, this Australian state launched the Melbourne Water Plan, which eventually led to the choice of sea water desalination as a source of drinking water production. The Melbourne plant (the second desalination plant built by the Group in Australia following Perth in 2006), whose construction from 2009 mobilized nearly 25,000 people over three years, now covers one-third of the city’s water needs with a production of 450,000 m3/d. The plant’s environmental footprint was carefully studied, resulting in the following: a reduced lot size; green roofs with 100,000 native plant species; electric power coming partly from the state’s wind farms; full carbon offset by the purchase of certificates on the local market; and continuous analysis of the impact of discharges on marine salinity, in accordance with national regulations on biodiversity protection.
