What We Do Best

Reverse Osmosis Plants

At Environmental Engineering Services LLC (EES) our reverse osmosis solutions can be added to both small and large treatment facilities and tailored to suit heavy or continuous service, with varying capacities.


Vacuum Sewer Treatment

Flovac is a unique sewerage system that uses differential air pressure to clear sewage. It is ideal in rocky areas or areas where there is a high water table in that it requires a maximum of 1.5 m trenching only. It is also well suited to a hot desert environment. Flovac is a relatively maintenance-free system, with a 20-year warranty on the vacuum valves.


Sewage Treatment Systems

At EES, we design, build, supply, erect and commission sewerage systems and sewage treatment plants, using the latest wastewater technologies that are energy efficient, easy to manage and environmentally friendly.


Analytical Laboratory

The Analytical laboratory of EES was established in February 1985. It is established to support the Sewage and drinking water analysis of the MRM & WR plants managed by us. It is a fully equipped laboratory with qualified staff carrying out the analysis as per the APHA standard.  EES uses most advanced equipment to analyze Domestic Sewage, Industrial Wastewater and Drinking water and we continually strive to improve our standards ensuring a safe and clean environment to families and communities.


Waste Incineration Plants

EES offers a range of high-combustion incineration technologies. Waste incineration is a very effective way of reducing waste – by up to 95% – reducing the demand for landfill space. Incineration plants can be located close to the area of service, thus reducing the cost of waste transportation.


Water Quality Testing

Water issues are becoming extremely pressing worldwide, particularly in Oman. Increases in population and production have led to increased water use, creating a parallel rise in the production of wastewater. This increase in water use and wastewater requires more efficient testing and removal of by-products and pollutants.
