A DOP250 keeping feet
in British Guyana dry

The coast line of British Guyana is below sea level. With a rising sea level due to climate change, the inland water level is controlled carefully. This is done using drainage channels; here the water from the hinterland is collected. These narrow channels have the tendency to gradually silt due to local sediment deposits.

Overview of project with excavator and DOP on barge.

The National Drainage and Irrigation Authority is responsible for the maintenance of these drainage channels. For this job, they have acquired a DOP250 with cutter unit. The DOP is attached to an excavator, acquired at Waterking. The hydraulically driven DOP and cutter are powered by a separate power pack. The entire system is located on a pontoon – thus the complete instant dredger can be moved easily from one outfall channel to the next.

The pontoon is 2 sides with the DOP250 with cutter unit at the far end.

Chief Executive Officer of NDIA, Fredrick Flatts, says :“ Currently, NDIA has three pontoons, each having two excavators but they are no longer sufficient to cater to the drainage needs. This dredge will be moving from one outfall channel to another and was designed to be far more efficient since it can move to the outfall channels in a shorter period of time.” (Source : Guyana Chronicle)

The DOP250 is attached to max 500 m discharge piping.

The DOP dredge pump is a vital addition to easily manage the growing need in drainage capacity.
