| Of the 368 km3 of wastewater that pass through the world’s sewers each year, only 60 km3 are treated and 7.1 km3 recycled. Local authorities that have already invested in wastewater treatment facilities to improve public health in their areas are now beginning to regard treated wastewater as an alternative resource that can help them conserve their natural resources. |
 In 2006 as in earlier years, Degremont signed new contracts, delivered facilities, installed plant and was operating wastewater facilities around the world. In France, its teams proudly delivered facilities for Clermont-Ferrand (400,000 e.p.), Brest (60,000 e.p.), Toulon (Toulon Est facility, 80,000 e.p.) and Pont-an-Illis in Finistère (2,500 e.p.). Internationally, the year began with the signing of a contract in Budapest, Hungary, to build a 1.5 million p.e. plant in Csepel. And it ended with the acceptance of the Warsaw facility and three others in South Korea.
All these facilities use specific processes to remove suspended solids, organic pollution, nitrogen and phosphorus as required. |
| Re-use: a major commitment for our customers |
 Where a local authority opts for re-use, Degremont adds a tertiary treatment stage, using conventional drinking water production technologies such as sand filters, membranes and ultra-violet to ensure that the recycled water is absolutely safe for public health. Recycling wastewater as a step towards sustainable development is a major commitment for our customers. The city of Doha in Qatar, for example, entrusted Degremont with the construction and ten years’ operation of one of the 135,000 m3/d facilities that will recycle its wastewater for irrigation purposes. This contract came just a few weeks after the opening of the facility in San Luis Potosi in Mexico, where recycled water will henceforth be used in agriculture and industry.
At the end of the year another emblematic contract was signed, this time for the town of Pimpama in Australia. Of the 17,000 m3 a day to be treated at the plant, 9,000 will be further treated so that it can be piped to households via a parallel distribution network and re-used to water gardens. |
