About Us

Since 2002, Darwish Polycon LLC has been manufacturing top-quality water storage tanks in Oman. Based in the Rusayl Industrial Area, our modern facility produces durable, food-grade tanks that meet the highest international standards.

Our legacy stems from Polycon Gulf Ltd, UAE, a pioneer in the Gulf’s polyethylene tank industry since 1993. Built to last, Darwish Polycon tanks are designed for years of high performance and safe potable water storage.

Premium Raw Materials

At Darwish Polycon, we use Linear Low-Density Polyethylene (LLDPE), known for its:
