Rainwater (if given the chance to infiltrate) eventually becomes groundwater. Groundwater is advantageous to harvest as it is always accessible (in spite of the timing of the rainy season), has a high storage capacity with good water quality (usually), is resilient to inter-annual climate variability and has a low cost relative to alternative sources.
