Sawaco produces 30,000m3 of unbottled water per day.

In February 2018, Saudi Arabia’s Saline Water Conversion Corporation was recognised by Guinness World Records as the largest water desalination company in the world. Now, another Saudi Arabian desalinated water provider, named Sawaco, has partnered with American company Gradiant Corporation to boost the efficiency of its plants.

As part of the agreement, the American firm will deliver its counter-flow reverse osmosis technology for the water supplier. The technology extracts fresh water from the brine reject stream and can yield twice as much as fresh water from Sawaco's plants without requiring extra seawater or pretreatment works.

Gradiant Corp said its technology has been picked due to the shortage of fresh water resources in Saudi Arabia, which will soon be home to the world's largest desalination plant.

Jeddah-based Sawaco owns and operates desalination plants that produce more than 30,000m3 of unbottled water every day. However, the company continues to face demand for the expansion of tis water production network.

Anurag Bajpayee, Gradiant’s co-founder and chief executive officer, said the company's technology will double Sawaco’s water production capacity without the need for expenses related to pretreatment infrastructure.

Commenting on the introduction of Gradiant’s technology, Nizar Kammourie, Sawaco's chief executive officer, said: “Gradiant’s technology will improve the economics, energy efficiency, and environmental footprint of our operations.”

Kammourie added that sustainability has been a crucial element for the long-term profitability of the Saudi business.

Water shortage is a key priority for regional governments. According to the organisers of Saudi Water Forum, held in Riyadh on 17-19 March, 2019, the kingdom’s per capita water consumption is among the world's highest, which "is in conflict with its environmental conditions".
