Duqm-Haima pipeline and renewable energy desalination plants mark leap towards water security

Duqm –  A series of strategic water infrastructure projects were inaugurated in Al Wusta Governorate on Wednesday, marking a major milestone in advancing water security and renewable energy integration in the region.

The centrepiece is the Duqm-Haima Water Supply System, a 211km pipeline project executed by Nama Water Services at a cost exceeding RO 24 million. Designed to meet the growing demand for potable water, the project ensures a more sustainable and reliable supply across the governorate.

The inauguration was held under the patronage of Sheikh Ahmed Musallam Al Kathiri, Governor of Al Wusta.

The project features four key pumping stations:

• Duqm Station – Fully equipped with mechanical, electrical and electronic systems, supported by a diesel backup generator.
• Al Ajaiz Station – Includes 1,000m³ ground and 200m³ overhead tanks, and a truck filling station with magnetic regulation.
• Abu Madabi Station – Houses a 1,000m³ ground tank and smart-monitored truck filling station.
• Haima Station – Comprises a 5,000m³ ground tank, 600m³ overhead tank, truck filling facility, administrative offices and a water quality lab.

Aligned with Oman Vision 2040 and the national carbon neutrality goals, several renewable energy-powered desalination plants were also launched. These initiatives leverage solar and wind energy to reduce reliance on fossil fuels in water production.

Key initiatives include:

• Dhiya 1 (Jazzer) – A 60kW solar-powered well in Wadi Ghadan.
• Rounb Truck Filling Station – Powered by 30kW of solar energy.
• Khamkham Plant (Haima) – Produces 42kW/hour of power.
• Nafi Plant (Mahout) – Provides 400m³/day via reverse osmosis.
• Dhaher Plant (Duqm) – Capacity of 38kW/hour.
• Hajj Plant Expansion (Mahout) – Adds 500m³/day with 40% brine reuse; total output 3,300m³/day.
• Jazzer Hybrid Plant – Generates 240m³/day using solar, wind and conventional sources.
• Al Kahl Plant (Jazzer) – Upgraded with reverse osmosis.
• Najda Plant (Mahout) – Expanded to 500m³/day of agricultural-grade treated water.
• Rehabilitation of six truck filling stations in Mahout and Duqm to enhance distribution.

Two wastewater treatment plants were also inaugurated:

• Mahout Plant – Uses constructed wetlands to treat 600m³/day to Grade 1 standards.
• Jazzer Plant – Employs aeration, oil separation, and reed beds for efficient five-day cycle treatment.

These developments reflect Oman’s strategic commitment to sustainable water management, technological innovation and environmental stewardship.
