Banger polder
Dutch regional water authority Schieland and the Krimpenerwaard and the city of Semarang has spent the last nine years to realize a 570 ha polder at the mouth of the Banger river with a drainage channel and an outfall pumping station.

The reason for the Dutch-Indonesian cooperation is the regular flooding in the low-lying districts of Semarang on the island of Java.

Polder board
The cooperation also included the assistance in setting up a polder board based on the Dutch model. This includes the collection of a small fee for the maintenance of the infrastructure. The board is also tasked to keep the drainage canals clean from garbage.

The board consists of eight people, including three residents of the area, three professors and two people from the government.

The technical design was done by Dutch consultancy firm Witteveen + Bos, financed by the Dutch programme Partners for Water.

The institutional part of the project was managed by Regional Water authority Schieland and the Krimpenerwaard and was financed by VNG international and the NWB-Waterfund.
