After King Rama IV made a river journey to Si Tha Palace he decided to have water from the river used in the Buddhist ceremonies at Wat Phra Phuttha Bat. He later introduced it into the royal coronation and other sacred royal ceremonies.

Water from 5 rivers was ultimately used in the ceremonies, these are the Bang Pakong River (Bung Phra Achan, Nakhon Nayok Province), Pasak River (Tha Rat, Amphoe Sao Hai, Saraburi Province), Chao Phraya River (Tambon Bang Kaeo, Ang Thong Province), Ratchaburi River (Tambon Daowadung, Samut Sakhon Province), and Phetchaburi River (Tambon Tha Chai, Phetchaburi Province).
