The subdistrict is named after Khlong Somdet Chao Phraya, a khlong (canal) that runs through the area to the west and ends at the Khlong Bang Sai Kai in the neighbouring district Thon Buri. It has a total length of 2.5 km (1 mi), a width of 4–11 m (13–36 ft) and an average depth of 0.6 m (1 ft 11 in). Currently, it is only a small waterway.[2]

The name "Somdet Chao Phraya" is a Thai noble title, derived from the canal's being excavated during reign of King Mongkut (Rama IV) by the nobility of this rank in the Bunnag family as well as being their residence. Not only this khlong, but also including other khlongs in Khlong San neighbourhood most of them were excavated by members of Bunnag family, such as Somdet Chao Phraya Borom Maha Prayurawongse, Somdet Chao Phraya Borom Maha Phichai Yat, and Somdet Chao Phraya Sri Suriwongse. In addition, they are also the renovators of many wats (temple) in the area, for example Wat Phichai Yat, Wat Anongkharam etc.[3]

Because it was the location of the customs house and also the site of royal warehouse, with Talat Ban Somdet, the local market that was the source of imported products from foreign countries as well.
