//Water-infrastructure programme
Implementation of Flood Protection Measures in Various Areas of the Eastern and Northern Coast (Package 1 — Group 2)
Deep in the Hajar mountains of the UAE's eastern coast, National Contracting is building a generational line of defence against flash floods — three dams, protective dikes, a flood-conveyance channel and water infrastructure that together secure close to 2.8 million cubic metres of storm water.
Commissioned by the Ministry of Energy and Infrastructure, this single programme unites nine major structures across three mountain-and-coast locations — Wadi Shees, Dhadna, and Qidfa & Murbah. Roller-compacted-concrete gravity dams, composite embankments, stone-lined channels and protective dikes are engineered to capture flash floods before they reach communities, store the water, and release it safely through controlled bottom outlets. It is among the most technically demanding civil works on the eastern coast — and a flagship of National Contracting's water-infrastructure capability.
Programme structures
Location 01 · Wadi Shees
A 36.5-metre roller-compacted-concrete (RCC) gravity dam set deep in the mountains of Wadi Shees — engineered to arrest flash floods and bank 610,000 m³ of water behind a reinforced-concrete wall, released on demand through an HDPE bottom outlet with an electric valve.
Location 02 · Dhadna
A 328-metre composite embankment dam pairing roller-compacted concrete with engineered fill (A1, A2, F1) and a rock-armour layer (R2) — the largest reservoir of the programme, impounding 1.187 million m³ of flood water behind a waterproofed core.
Location 02 · Dhadna
A 1,594-metre flood-conveyance channel carrying released water safely through Dhadna — a 1,370 m trapezoidal stone-lined reach, a 178 m U-shaped reinforced-concrete section, and twin box culverts (3-cell and 4-cell) threading the flow beneath roads and crossings.
Location 03 · Qidfa & Murbah
At Qidfa and Murbah the existing dam basin is expanded by 999,000 m³ and refurbished, flanked by two new protective dikes — a 1,628 m earthen dike (Dike-02) and a 1,510 m concrete dike (Dike-03) — together forming a 3.1-kilometre shield against coastal flooding.
Companion water works
Two new potable-water pumping stations — a main station and a booster station — built alongside the flood works to safeguard and distribute the community's drinking-water supply, delivered to the same standard of finish as the dams themselves.
Access & connectivity
A finished road bridge spanning the Dibba waterway — completed crossings, landscaped promenades and feature lighting that knit the coastal community together while the flood network quietly protects it.
From the first survey to the final handover, National Contracting delivers infrastructure the nation relies on every day.
