Central oil deposit, Oil storage facility in Nelahozeves, Czech Republic.

The Central oil depot is an industrial facility in Nelahozeves that stores crude oil in large tanks for regional distribution. The site operates pipelines and maintains petroleum reserves as part of the national energy infrastructure.

Construction began in July 1994 on the site of a former sand pit, after EU accession talks required 90 days of strategic oil reserves. Between 1994 and 1998, four tanks of 50,000 m³ and six of 100,000 m³ were built; expansions in 2001–2004 and 2006–2008 added 125,000 m³ tanks, and another was completed in 2020.

The site's Czech name, Centrální tankoviště ropy Nelahozeves, is used by operator MERO ČR, a. s. The terminal branches of the Družba and IKL (Ingolstadt) pipelines end here, and most stored oil belongs to the Administration of State Material Reserves. The tanks are filled and emptied according to refinery demand in Litvínov and Kralupy.

The site covers about 59 hectares across the cadastral areas of Nelahozeves, Uhy, Nová Ves and Sazená, north of Nelahozeves. It is a fenced operating facility of MERO ČR with no visitor access; the tanks can only be seen from outside the perimeter.

The tanks are above ground, not underground: steel cylinders with double bottoms and double shells, and floating roofs that rise and fall with the oil level. The largest, seven of 125,000 m³ each, measure 84.5 m across and 24.1 m high. Firefighting water is drawn from the Vltava river.
