WACASCO was established in 1982 and is a member of the OMZEST Group since its inception. WACASCO is one of the largest catering organizations in the Sultanate of Oman with over 800 employees, specializing in industrial catering. It provides the following services:

Exploration and development of oil, gas and mineral resources and work on major construction sites in the Sultanate of Oman has been associated with the growth of an efficient catering industry which serves the needs of thousands of workers employed at mining and construction camps in remote areas. Feeding and accomodating workers of differing ethnic backgrounds has brought about a highly specialized trade capable of meeting widely varying requirements of the many client organizations, some of which are situated in extremely oppressive and remote areas where communication and access is always a challenge. Some of the largest locations where WACASCO has assumed the role of industrial caterer include the Bahwan Engineering Company and Dodsal & Co, sites at the Oman LNG Site in Sur, Magan/Sohar Copper Mines, several operations related to oil development and production at Fahud, Marmul, Rima, Bhaja including drilling camps, pipe laying camps, seismic mobile camps, power station construction camps and road laying and maintenance camps.

This contract included the preparation and service of meals to over 3,600 students, the VIP restaurant at the Faculty Club and full management of the University Staff Club with over 600 members.

WACASCO had the distinct privilege of serving the elite troops of the Ruler, the Royal Guard of Oman for a period of 5 years from July 1991. The massive operation involved providing catering services to over 3,000 soldiers at 26 different locations. The most difficult and enduring service under most trying conditions was to provide meals to the soldiers during His Majesty's "Meet the People" tours.
