Important initial questions to be asked: 
- how clean is the water that must be drained?
- what do you intend to use the water for? 

When the ditch is shallow and there is relatively little water, there is a chance that suspended solids will be sucked up alongside the water. This should always be prevented when using irrigation and booster pumps, as these pumps are not intended for such purpose. This can be done by means of a filter on the hose. Nevertheless, always remember a filter can also become clogged, causing the pump to run dry.

Submersible pump
A solution may be a submersible pump that can process suspended solids up to a certain size. The submersible pump is completely immersed in water and sucks the water from the ditch or canal. The pump is cooled by the ditch water, meaning it should always be completely immersed when active. These pumps can process suspended solids up to 35 mm. Another advantage is that these pumps are ideal for draining any excess water.
The submersible pump is useful for occasional use. These pumps cannot run continuously and often have less power and pressure compared to irrigation pumps, so this may be a disadvantage when pumping a lot of water.

Irrigation pump
Irrigation pumps are ideal pumps for filling ponds, canals, water basins, reservoirs etc. These pumps are known for their high pressure output. The advantage of this is that they can pump large amounts of water in a relatively short time. Think of filling ponds or reservoirs, for example. In addition, these pumps can also be used for irrigation purposes, horse bins, larger areas of land or your garden. These pumps are easy to connect to sprinklers.
One disadvantage is that the pump is unable to process suspended solids. However, special hoses with filters can be purchased for this, please see Suction hoses
Please note that the end of the hose is not located at the bottom of the water source, but is freely immersed in the water. Otherwise the filter may clog up and your pump will run dry.

Booster pump
A booster pump is basically an irrigation pump with an expansion vessel attached to the bottom. The benefit of these pumps is twofold:
- the expansion vessel allows for greater water pressure
- the required pressure can be directly controlled by the pump

These pumps can also be fitted with special hoses that prevent suspended solids from entering the pump. 

Another major advantage is that these pumps are highly suitable for maintaining high pressures in water pipes. For example, the use of a tap and shower at the same time or in combination with a washing machine, dishwasher or second shower. These pumps are available via the following link:
