Elevation Residences - Ethiopia

Ethiopia chooses a wastewater treatment plant by ESA to promote environmental sustainability in the USA Embassy's accommodations. Inspired by western sustainability model and guided by the need to better enhance such a precious resource as water, the Elevation Residences - an elegant residential building located in the earth of Addis Ababa for the USA Ambassadors in Ethiopia - has chosen ESA to give a second life to water that will be used inside the building. The structure, in its completion stage, thanks to the solution adopted, will be the first residential purpose building in the Country to be completely eco-sustainable in the reuse of the wastewater coming from the sanitary facilities, which will be used for irrigating green areas dedicated to leisure. ESA's wastewater treatment plant is equipped with MMBR (Moving-Bed Biofilm Reactor) technology and PLC for the automation of every phase of the treatment process; provided of a sand filter for the final filtration of the water, it's able to carry out the backwash mode autonomously, thanks to the pneumatic valves with electric actuator managed by the PLC: a feature that guarantees high efficiency of the process, an even longer duration of the filters and ensures minimal maintenance interventions.

CAS waste water treatment plant in Ethiopia

The Homeland Hotel , a new 4-star facility that uses modern technologies and our CAS (Conventional Activated Sludge) treatment plant, has been inaugurated in Mekele (Ethiopia) The lack of adequate space for the installation of a common wastewater treatment plant was an opportunity for ESA to design and build a 20 cubic meters CAS (Conventional activated sludge) system under the flooring of the hotel lobby for 150 equivalent inhabitants, consisting of a single tank in reinforced concrete divided into four partitions, which allow to significantly improve the efficiency of the system and the quality of the water introduced into the sewer system. The solution of made-to-measure stainless steel manhole covers has allowed the system to be fully integrated into the context and visually imperceptible, thus guaranteeing a discreet solution for the hotel and customers, also ensured by the "odor-free" system, which does not allows the release of any odor.
