There is one opening that is 12 m wide with segmental valve.
Itebej and Klek sluices
Itebej and Klek sluices were built just before the First World War in 1914 within the scope of works on regulation of the river Begej from its confluence with the river Tisa up to Timissoara. These two sluices are almost equal. The main task of both sluices is to maintain the water level in the Begej at a necessary level in periods of low and medium flows. The pening is 22,5 m wide . Water level regulation is carried out with plate valves in the frame construction – “Poire” system.
Stajićevo Sluice
It was built in 1969. The sluice regulates water flow and level in the river Begej.
In periods of exceptionally high water levels in the Tisa it separates waters of the Tisa and Begej and prevents water from the Tisa to flow in Begej downstream from the sluice. Its maximum throughput is 310 m3/sec of water from the Begej into the Tisa. There is one opening that is 24,5 m wide and segmental valve with flap.
Botos Sluice
Botos Sluice was built in 1971 near the settlement Botos, at the route that the river Brzava used to flow along before the construction of the Hs DTD canals.
