The story of the well started once Allah ordered Prophet Ibrahim (pbuh) to leave his wife Hajar and her son Ismail in an ‘uncultivated valley’–another name for Makkah.
When Ismail’s food and water ran out, his mother was desperately searching for water for her infant son, but she could not find any, as Mecca is located in a hot dry valley with few water sources.
She started running back and forth from Safa to Marwah searching for water. At that point angel Gabriel (peace be upon him) pumped the water from under the child’s feet. Hajar immediately drank the water and fed her son.
Hajar ran seven times back and forth in the scorching heat between the two hills of Safa and Marwah, looking for water. Getting thirstier by the second, the infant Isma’il scraped the land with his feet, where suddenly water sprang out.
There are other versions of the story involving God sending his angel, Gabriel (Jibra’il), who kicked the ground with his heel (or wing), and the water rose .It is the well that hasn’t dried out for over 5,000 years!
Nowadays the General Presidency for the Affairs of the Grand Mosque and the Prophet’s Mosque periodically carries out maintenance work for the equipment and devices of Zamzam water stations, according to the preventive maintenance plan established in advance.
It is supervised by a trained group of engineers and technicians to ensure its quality before presenting it to the guests of the House of God, the kabba, from the Umrah pilgrims and Hajj pilgrims, and to ensure that it is implemented according to the echnical tracking principles and issuance of corrective work orders in case of any malfunctions and their immediate implementation within the stations.
Zamzam water passes through the latest sterilization systems (ultraviolet units) to kill bacteria and viruses with ultraviolet rays, a high level of sterilization, while one kilowatt of electricity sterilizes 12,000 gallons of water to ensure that Zamzam water does not change color, taste or smell.
Ultraviolet rays are used in sterilization and filtering as it is light energy produced from low-pressure mercury lamps protected by special types of glass, allowing light to pass through to bacteria, viruses and other microorganisms, penetrate the outer envelope and destroy DNA [D. N. A].
The water is entered into a cylindrical tube inside which there are lamps that generate ultraviolet rays, and the number of lamps inside the cylinder depends on the size of the cylinder, the amount of water to be sterilized, and the speed of entering the water is adjusted so that it is fast enough to kill any bacteria or viruses.
In order to preserve the safety of Zamzam water, the Agency for Technical and Service Affairs takes a set of measures, starting with pumping the blessed Zamzam water from the Zamzam well in a closed circuit through filters that trap sand and impurities.
Water passes through stainless steel pipes until they reach completely closed tanks, then pass the sterilization devices, and the same mechanism takes place when it is transferred to the Grand Mosque through a team of specialists who supervise these works.
These services and efforts come under the supervision and organization of the General Administration for Operation and Maintenance of the Agency for Technical and Service Affairs.
