NSF/ANSI 61 (Gidauniyar Tsaftar Tsaftar Kasa)
This is the North American gold standard, globally recognized for water treatment and storage. If a geomembrane carries an NSF 61 certification, it means the material has undergone rigorous extraction testing. Laboratories have verified that no dangerous contaminants—such as lead, arsenic, or harmful organic compounds—leach into the water at levels exceeding established health thresholds. Most international municipal projects will boldly mandate "NSF 61 compliant" a cikin takardun su.

Polyethylene Mai Girma (HDPE)
HDPE is the most widely used material for large-scale potable water reservoirs. It does not require plasticizers to remain flexible (unlike PVC), meaning there are zero plasticizer chemicals available to leach into the water over the 30-year lifespan of the reservoir. For drinking water, we extrude HDPE using exclusively 100% virgin, food-grade resin. Absolutely no post-consumer or industrial recycled material is permitted in the manufacturing process.
