Astana's heating system turns green to detect hidden leaks faster
Green Dye to Be Added to Astana's Heating Network on April 4 to Detect Leaks
On April 4, sodium fluorescein (Uranine A), an organic dye, will be introduced into Astana's district heating system, potentially giving the water a greenish tint, the city's heat supply operator Astana-Teplotransit JSC announced.
According to the company, the dye will help identify losses of network water caused by hidden defects in pipelines, loose fittings in water heaters, or leaks in consumer heating systems, allowing for timely repairs.
"Uranine A is non-toxic, approved for use, and permitted in heating systems as a tracing dye. Its use will not affect tap water quality, but if it appears in hot water, it indicates a fault in the water heater," the statement reads.
If hot water from the tap turns green, residents should immediately report it to: - Ikomek emergency service at 109; - Astana-Teplotransit's 24/7 dispatch service at 77 12 00 or 77 12 11; - The tuning service dispatcher (weekdays, 8:00–12:00 and 13:00–17:00) at: - 79 88 96 (for the Yesil and Nura districts); - 39 69 11 (for the Saryarka and Baikonur districts); - 77 12 92 (for the Almaty and Sarayshyk districts).
