The district is named after Khlong Thawi Watthana, a very long Khlong that runs roughly northwest-southeast through the area. It was a tambon, part of Amphoe Taling Chan of Thon Buri province, back in 1933. It was promoted to a district effective from 6 March 1998. Much of the land is used for agriculture with many khlongs providing water to the orchards. However, they are gradually replaced by housing projects along the district major roads.
Utthayan Road (ถนนอุทยาน), the road toward Phutthamonthon, is one of the most beautiful avenues in Thailand. The road is 90 m wide, about 3,861 m long, and divided into the central avenue and two parallel lanes along both sides. The light posts along the length of the road is decorated with Hongs (หงส์, a bird in Thai mythology). The road was planned as part of the grand Phutthamonthon project of Field Marshal Plaek Pibulsonggram, the then prime minister, during the 1950s. The project was stalled when he went out of office and only resumed and opened as recently as 27 February 1999. The original name of the road was Aksa (อักษะ), the Thai name for The Axis.
