In implementation of Hatta Comprehensive Development Plan launched by His Highness Sheikh Mohammed bin Rashid Al Maktoum, Vice President, Prime Minister and Ruler of Dubai, at a cost of AED 1.3 billion, the excavation works of Hatta Development Project have been started. The Executive Council of Dubai said that the project is progressing according to the scheduled objectives, in participation of a group of government authorities responsible for the implementation of the series of projects and initiatives of the plan with the aim to establish the basics of Hatta sustainable development.
The Dubai Electricity and Water Authority (DEWA) commenced the establishment of a hydroelectric power station that will make use of the water stored in the Hatta Dam. An important part of the engineering studies of the project have been completed, including design, hydro-geological, geological, environmental, and geotechnical studies, piling, design of deep water tunnels, upper reservoir, and hydroelectric power station.
The power station is the first of its kind in the Arabian Gulf, with a total capacity of 250MW, and a lifespan of 60 to 80 years. It will positively contribute to many fields, including irrigation, flood control, and storing fresh drinking water. It will increase dependency on clean energy sources, support the sustainable development of the region, and Enhance Hatta as one of the most popular tourist attractions.
Furthermore, Dubai Municipality completed the feasibility study for the sanitary drainage project in Hatta and commenced the preparation of the required designs. Such project is described as "Project of Century" costing AED 30 billion.
It should be noted that the implementation of the project will take six years as construction is expected to begin in 2019 and end in 2025. The project will be implemented in two phases; the first in Deira where the wastewater flows will be transported to Al Warsan Sewage Treatment Plant, and the second in Bur Dubai where the wastewater flows will be transported to Jebel Ali Sewage Treatment Plant.
The Bur Dubai Tunnel will be 62 km long and have 112 km of main drainage lines, while the Deira Tunnel will be 16 km long with 34 km of main drainage lines. In addition, the current pump stations will be operated. The Bur Dubai Tunnel will begin with 26 m with a complete slop up to 100 m in deep. Additional phases may be implemented to serve the new development areas or connect Deira and Bur Dubai.
The underground sewage lines will be built using innovative tunnel technology to minimize the damage of construction works. The innovative tunnel technology will ensure throughout the project the reduction of the construction damages on the land surface, including roads, passages and other utilities. The implementation of the strategic tunnel development program is vital to reduce the excessive absorptive capacity on sewage and to cope with the expected increases of sewage coming from new areas of development and population growth, by providing environment-friendly solutions with the lowest level of carbon emission.
