Built to run
for decades.
Since 1989, we have designed, commissioned and operated wastewater treatment plants across Oman. We build for long-term performance and support every plant after handover.
One accountable team,
no handoffs.
EES designs, constructs, commissions, operates and maintains water and wastewater infrastructure across the Sultanate — from municipal sewage treatment plants to produced-water systems for oil & gas.
Our own laboratory closes the loop: sampling, analysis and compliance reporting on every plant we run.
Wastewater is not
the end of the cycle.
We treat it as a resource. Every plant returns water to irrigation, industry, aquifer recharge and the environment — relieving the Sultanate’s freshwater reserves.
Thirty-seven years, still flowing.
EES opens in Ghala Industrial Estate as a specialist environmental engineering house for the Sultanate.
Sewage, effluent and grey-water treatment plants delivered across the governorates — municipal and industrial.
Long-term operation and maintenance contracts; the in-house laboratory closes the compliance loop.
More than seventy projects delivered; live works from the interior STPs to Raysut, Salalah.
Quality is not a certificate on the wall. It is thirty-seven years of plants that simply keep working.
Ready when your water is.
