The kanji 浩 is a 形声文字 (keisei moji), a phono-semantic compound character. It is composed of two parts: the water radical 氵 (also written as 水, meaning "water") on the left, and the phonetic component 告 (koku) on the right. 告 originally meant "to inform" or "to announce," but it also contributes the sound コウ (kō) to the kanji. The combination of the water radical with the sound and the suggestive meaning of the phonetic component 告 conveys the idea of an abundance of water or something expansive like a vast sea or a boundless expanse.
