Sarroch borders the following municipalities: Assemini, Capoterra, Pula, Villa San Pietro.

Sarroch population grows to about 10,000 in the summer due to the tourist flow in the zones of Perda e Sali and Portu Columbu.

It might derive from the Phoenician "Sharak" meaning "bunch of grapes", or perhaps from the Catalan "S'arroch", with reference of the majestic rock that dominates the village.

Sarroch is the location of the oil refinery Saras S.p.A. owned by the Moratti family.

The refinery is one of the biggest in Europe and was the subject of scandals related to pollution and public incentives for renewable energy sources and also worker security.
