Saudi: Stirling Lloyd passes Zamzam water tests
Stirling Lloyd’s Permare EPW Tropical coating has been approved for use on Zamzam’s water storage structures, which supply water to Mecca, Saudi Arabia
Stirling Lloyd’s Permare EPW Tropical coating has been approved for use on Zamzam’s water storage structures, which supply water to Mecca, Saudi Arabia.
Created by the Saudi Geological Survey (SGS) and set up by the Zamzam Studies and Research Centre (ZRSC), the latest standards are designed to ensure the quality of water used by pilgrims visiting the Holy City.
The programme aims to revalidate and improve previous product approval processes connected to Zamzam water facilities.
James Hopper, Stirling Lloyd’s regional sales manager – Middle East, commented: “The key requirement of the new programme is to provide durable internal protection to the concrete Zamzam water-holding structures, with suitable coatings [and] without affecting water quality.
“Several previously approved coatings failed this new testing regime, despite providing credible international certification,” he revealed.
Stirling Lloyd’s Permare EPW Tropical is a durable, seamless, liquid-applied coating that has been used to provide internal protection for Zamzam’s water storage structures since 2004. The latest round of tests confirmed the product’s compatibility with potable water, ensuring the retention of its flavour, chemical composition, and curative properties.
Additional experiments, which were limited to the supplied material within set conditions, tested the product’s leaching at temperatures of up to 50°C. Permare EPW Tropical passed the requirement, proving that it did not promote the growth of aquatic microorganisms.
Anis Ur Rehman, sales manager – utilities, at Stirling Lloyd Middle East, said: “It is safe to say that the Zamzam water supply is protected by a new and uncompromising testing regime, which filters out substandard products. Stirling Lloyd is pleased to be continuing to help protect a continuous supply of Zamzam water to serve the kingdom and millions of pilgrims from around the world.”
