About the labs

The Alexandria Water Company supplies nearly 6 million citizens with pure drinking water. The service areas extend from Alexandria Governorate, part of Buhaira Governorate, and the northern coast.
The Alexandria Water Company consists of 11 purification stations, each of which includes an integrated laboratory equipped with the latest special laboratory devices to conduct various laboratory experiments, in addition to the central laboratory for research and quality and environment management.



The laboratory for each station uses the following machines:
1- Monitoring the water treatment process in its various stages over the course of 24 hours, by conducting the necessary physical, chemical, bacteriological and biological analyzes according to the internationally defined methods.
2- Determine the optimal doses of chemicals used in treatment processes (alum and chlorine).
3- Monitoring the pure water network of the treatment unit.
4- Participate in solving emergency operating problems on processing units

The Central Laboratory for Research and Quality Control consists of five basic departments, namely:
1- Organic Chemistry Research Department: 
It is equipped with the latest devices for the detection of organic pollutants such as pesticides, herbicides, chlorinated and halogenated pesticides, as well as for the detection of halogenated and cyclic organic pollutants. The latest equipment has been used, such as:
Chromatographic analyzer with mass detector
The chromatographic analysis unit using a mass detector is an integrated unit through which it is possible to detect and identify concentrations of substances and volatile and semi-volatile organic pollutants of unknown composition.
The mass detector is one of the detectors with a high level of accuracy. This unit is used to verify the compounds that other chromatographic analyzers detect and estimate their concentrations with a very accurate degree.



2- Inorganic Chemistry Research Department:

And for the analysis of inorganic elements, including heavy metals, it is equipped with a spectral analysis device using plasma (ICP), which is the latest device in the field of measuring heavy metals such as lead, mercury, and chromium in fresh water, which can represent a threat to human health. Therefore, the device that can be monitored was chosen. This type of metal, no matter how low their concentrations.

3-   Bacteriological Research Department:

The laboratory performs microbiological analyzes such as detecting signs of bacterial contamination with the latest laboratory experiments, using the fastest and most modern international methods to obtain results within 24 hours, including:

TheCR devices laboratory also detects viruses using the latest P

4- Biological Research Department:

Bacterioacterialogical group coli b
Streptococcus faecalis
The total number of bacteria
The laboratory performs a complete biological examination of water samples using the latest microscopes equipped with a television imaging unit and equipped with a special program for counting and classifying microorganisms, including.
Parasite monitoring
5- Quality Control and Environment Department:

Who performs his supervisory role in evaluating the performance of each of the stations and the laboratory of each station.

It is a new department that was recently established in the laboratories sector to supervise the application of all quality standards on analyzes in accordance with the international standard of ISO 17025 for the year 2005. In order to reach the best cup of water offered to the citizen, all standards of safety, health and quality are applied to it, starting from bringing samples through supervising the calibration of devices To ensure the validity of the analyzes until the results are issued through an integrated program that starts from encoding the sample using the bar code device until extracting the results electronically to ensure that no errors occur during the exchange of samples
Participate in an integrated program with other ISO 17025-certified companies to exchange joint analyzes in order to obtain the best results and apply the latest methods in analyzes
The department follows a department for preparing and bringing samples and is equipped with the latest devices necessary for measurements during the trip and keeping them in special refrigerators to ensure that they arrive intact to enter the laboratories to conduct analyzes on them.
The application of the GIS system to collect samples of the network with the latest devices to identify places and facilitate follow-up and solve problems related to citizens' complaints
Participate with central laboratories in preparing to obtain ISO 17025 to reach the highest level of performance and follow the latest methods and techniques for analysis to obtain the best results.


  • The central laboratory has an important role in
    1- Monitoring the intakes of the various stations.
    2- Monitoring raw water sources, which include the Al-Mahmudiya and Al-Nasr canals, in addition to the Rashid branch.
    3- Monitoring the pure water network of the city of Alexandria and part of the lifts of the northern coast.
    4- Analysis and evaluation of chemicals and raw materials used in processing operations.
    5- Carrying out research related to the development of water treatment processes and examining the extent to which they can be applied in practice.
    6- Paying attention to consumer problems by examining the causes of complaints and overcoming them.
    7- Applying the quality control and assurance program (QC & QA) on all analyzes conducted in all the company's laboratories.
    8- Using the mobile laboratory to conduct surveys and field experiments in a timely manner to follow up the water quality. The Alexandria Water Company, in cooperation with the USAID, requested a field experiment unit, and the unit was actually supplied.
    9- The laboratory is served by a fleet of vehicles equipped with all the necessary devices for measurements during the trip and keeping them in refrigerators to ensure their safe arrival in order to enter the laboratories to conduct analyzes on them.
    10- The central laboratory performs the analysis for third parties at an appropriate fee, according to the type of analysis.
