Abstract:
A watering device for deployment within soil for watering vegetation by releasing water into the soil in which the vegetation is growing. The device includes a container that is shaped for being deployed at least partially within soil. The container has an inlet for receiving a flow of water into the container and a plurality of apertures through which water can flow from the container. A flow-control assembly is coupled to the inlet of the container for regulating the flow of water into the container in accordance with a demand for water from the soil. The assembly includes a float disposed for rising and falling in accordance with the level at which water accumulates within the container; and a valve coupled to the float for regulating the flow of water into the container through the inlet in accordance with the level of the float. When the container is deployed at such a depth in soil that water can flow through the apertures of the container into the soil, and the soil becomes so saturated with water that the water flowing into the container accumulates within the container, the level of the float rises as the water accumulates and thereupon causes the float to rise until the valve shuts off the flow of water into the container through the inlet.
