Dubai Electricity and Water Authority (DEWA) reported that it is conducting several intensive stages to ensure the quality of desalinated water, to ensure that customers across the emirate are provided with drinking water of the highest international quality standards, including the World Health Organization standards related to the production, transportation and distribution of drinking water.
Saeed Mohammed Al Tayer, Managing Director and CEO of DEWA, said, “DEWA guarantees the quality of desalinated water, through continuous testing through the various stages of desalination, where samples are taken around the clock from seawater entering electricity and water production plants to examine several factors and characteristics. Including the amount of free chlorine remaining and the degree of turbidity, to ensure the sterilization process and the preservation of equipment.”
Al Tayer explained to "Emirates Today" that "the authority works through its devices to continuously monitor some characteristics of sea water, such as: temperature, salinity, the amount of dissolved oxygen in the water, pH and the amount of oil. It also analyzes the characteristics of sea water entering the stations and water returning to the sea. After the desalination process, such as physical properties, organic and inorganic chemical properties and microbiological properties according to international standards.
He added that "DEWA is also working continuously to sterilize water, to ensure that it is free of disease-causing organisms," noting that, in addition, the water goes through several stages of filtration before entering the desalination plants.
Al Tayer indicated that “the desalination process is carried out using the multi-stage separation technique (MSF), which depends on heating the water and converting it into steam and then condensing it,” stressing that this procedure in itself leads to water purification of any microbiological contamination.
In addition, the authority works, within the stages of water quality monitoring, to examine the water delivered to consumers on a regular basis on a daily basis, according to monthly and annual plans, as water samples are taken from the tanks of the authority, and from fixed points connected directly to the network at the level of all regions. Dubai, to ensure its validity and compliance with international standards in terms of chemical and biological terms.
Al Tayer stated that new water pipes are checked and sterilized and hygienic before entering service, pointing out that monitoring the quality of drinking water after the meter is the responsibility of customers, and therefore they must always ensure the cleanliness of tanks and internal connections.
