Rainwater is a useful and free source of water. Collecting and using rainwater is environmentally friendly because it reduces the need to use treated water from the tap. Rainwater is especially good for plants because it is softer than water from the tap. Rainwater can also be collected for washing and cooking. 

Using a knife, cut a piece of garden hose about 1 metre long, to the end of which you attach the connector for the nozzle. The end with the connector is used to attach it to the tarpaulin with which the rainwater is to be collected, while the rubber end of the hose is held in a container.

Cut a hole in the middle of a large plastic sheet so that the plastic tube can be inserted through it with the rubber end first. Carefully push the connector halfway through the hole until it is firmly inserted. The entire length of the hose now hangs out from under the tarpaulin. Secure the hose around the hole in the tarpaulin with strong tape. This prevents the hose from slipping out and rainwater from dripping down the side.

4 stakes of the same size are driven into the ground so that they can hold the 4 corners of the plastic sheeting above the ground. Each corner is attached to a stake. The corners of the tarp should be at least one metre above the ground. The tarp should be a little loose in the middle so that it hangs closer to the ground there. 

A container is placed underneath the tarp into which the end of the hose is inserted. In this way, the wide surface of the plastic tarp can collect a large surface area of rainwater and channel it through the hose into the collection container.
