ZENNE

The 'Zenne' (Dutch) or 'Senne' (French) is a small river that flows through Brussels, left tributary of the Dijle. The spring is in the municipality of Soignies. It is an indirect tributary of the Scheldt (through the Dijle and the Rupel). The Woluwe is one of the tributaries of the Zenne.
In total the Zenne is 103 km long.
In the centre of Brussels, the Senne was completely covered up and built over in the 19th and early 20th centuries. It is still visible in the outskirts of Brussels and outside the city. The Zenne is notorious for being one of Belgium's worst polluted rivers, since all effluents from the Brussels Capital Region are versed in it without treatment. This problem will be solved however in the near future since a sewage treatment plant is now under construction.
The Golden Iris became used as the emblem of the Brussels Capital Region due to its habitat in the marshy plains around the river. The unique seasonal wild yeasts of the Senne river valley are used in the production of the regional lambic style of beer.
Senne is also a Dutch first name, it comes from the name Sebastian.
