Our story
1976
IEI was founded in 1976 in the interior of Oman, and has grown alongside the Sultanate's water, power and public infrastructure.
Today the company operates as one integrated team — covering the full project life cycle from construction and installation through to long-term operation and maintenance — for government entities, utilities and the private sector.
Our headquarters remain in Nizwa – Karsha, Ad Dakhiliyah Governorate, close to the communities and assets we serve.
Mission
To deliver and sustain the water, power and infrastructure assets Oman depends on — safely, to a high engineering standard, and with lasting local value.
Vision
To be the trusted Omani partner for critical infrastructure, at home and for international firms working in the Sultanate.
