OTIZ focuses on reducing the consumption of tap water and soft water. The plant replaced underground conduits with exposed system to make it easier for inspection and maintenance. Each month, designated personnel compile and review statistics on all water withdrawal categories, and optimize the efficiency of equipment with high water consumption. In reference to the soft water, OTIZ increases the cycle of concentration at the cooling tower to reduce water softener regeneration, and increases reclaimed water through the concentrate from reverse osmosis system. The modifications delivered noticeable results by reducing tap water usage at the southern portion of the plant by 46% in 2020; soft water usage by 8%.
