Energy Globe Award

With more than 170 participating countries and over 1500 project submissions annually the Energy Globe Award is today's most prestigious environmental prize worldwide. It distinguishes projects regionally, nationally and globally that conserve resources such as energy or utilize renewable or emission-free sources. Award ceremonies are held all over the world. Prominent personalities as well as Energy Globe Ambassadors in 90 countries support the mission of Energy Globe. The activities of Energy Globe attract worldwide media attention - international TV stations report each year with approximately 1,000 hours of broadcasting time. The aim of the Energy Globe is to raise global attention on sustainable, everywhere applicable environmental solutions and to motivate people to also become active in this area.

National ENERGY GLOBE Award 2015

Submitted by: Dubai Municipality - Sewage Treatment Plants Department
Comprehensive wastewater management

50 years back, Dubai was depending on septic and soakaway tanks to get rid of domestic wastewater, until the early sixties of the last century when the first Sewage Treatment Plant was built in the city with an initial capacity of 5,000 m3/day which was increased to 50,000 m3/day later on. By that time, that treatment plant was not capable to cope with the fast growth of the city of Dubai, and the treatment system was also not efficient enough to produce a quality of treated wastewater that could be used for irrigation. New Sewage Treatment Plants with a higher capacity of 570,000 m3/day and a more efficient treatment system were built, which recycle the water so that it can be used again for irrigation without causing any hazard to the environment or public health. Management of water resources is very important in this region, since the annual rain fall is very low. Potable water is produced by desalination of seawater and costs around $ 3.0 per cubic meter while treating sewage costs only 14 Cents per cubic meter. Recycling of treated waste water is therefore the key to meet the horticultural needs. In line with the strategy of energy conservation & sustainability of Dubai’s government, the plants are designed with rationalized energy consuming processes and components like using gravity to avoid pumping, bio-trickling filters for ammonia reduction, biological scrubbers for odor removal, variable speed drives for selected pumping needs, advanced process automation systems, etc. The Arabian Gulf is spared of the possible discharge of high saline content brine, which is already a concern to the region. The by-products are 30 m cubic meters of methane gas per year and 7,000 tons of manure which are produced from sewage sludge. The manure is used for soil enrichment and the methane gas is used for internal heating and also planned to be converted to CNG for use in automobiles.



If you can plan it, you can achieve it!

Jury-Rating
Water is of vital importance not only to the people but also to the local economy in Dubai. 50 years back, Dubai was depending on septic and soakaway tanks to get rid of domestic wastewater, until the early sixties of the last century when the first Sewage Treatment Plant was built in the city. Later on, that treatment plant was not capable to cope with the fast growth of the city, and the treatment system was also not efficient enough to produce a quality of treated wastewater that could be used for irrigation. This year´s National Winner of the Energy Globe Award in Dubai built new Sewage Treatment Plants which recycle the water so that it can be used again for irrigation without causing any hazard to the environment or public health. Congratulations to your achievements!
