Water Supply, Wastewater Treatment and Sewage Disposal Projects

The lack of water supplies in Jordan has created a need to reuse treated wastewater for agriculture and to build efficient water networks within the country. Since 1979, ENEX Contracting Corporation has been a synonymous name with leadership in water project engineering and construction. We have worked hand in hand with the water authorities to develop some of the largest and most demanding water projects across the nation.

Our strength encompasses every aspect of engineering and construction. Our clients benefit from our expertise at every project stage, from conceptual studies, through design and engineering, to construction.

In a fast-changing world, where social and ecological priorities are increasing, we place the highest emphasis on quality, safety and protection of the environment. With this approach we remain committed to providing our clients with the optimum return on investment through innovation and engineering expertise.

ENEX has worked on all aspects of water supply and irrigation; constructing networks of irrigation channels, canals, tunnels, and pressure pipelines in most of parts of the country. ENEX has also striven to continue diversification in environmental engineering obtaining a number of projects for the collection and treatment of both municipal and industrial effluent.
