Pak Tho district
# Pak Tho district

Pak Tho (Thai: ปากท่อ, pronounced) is a district (amphoe) in the southern part of Ratchaburi province, western Thailand.

Pak Tho means 'mouth of a water pipe'. It originates from the fact that the area named Nong Thale ('sea pond') is rather low and thus during raining season was usually flooded. At the only outlet of this area the water current was strong like a water pipe.

## History

Around 1900, the government separated part of Mueang Ratchaburi district and created a new district named Tha Nat Wat Pradu (ท่านัดวัดประดู่). The district office was in front of Wat Pradu at the Khlong Wat Pradu in tambon Chom Prathat, today in Wat Phleng District. Tambon Pak Tho was included in this district. As it was also near the Om River, the district was also known as Maenam Om (แม่น้ำอ้อม). Later the district office was found to be inconveniently located. During the dry season the water level in the canal was too low and there was no road connection. In 1914 it was moved to a new location in tambon Pak Tho, near a railway station. The area around the old district office became the minor district Wat Phleng.

On 10 April 1991, the district was visited by Crown Prince Maha Vajiralongkorn. He was presented a petition by locals asking for help with local water resources, specifically the lack of water for farming. The crown prince passed along the need to the Royal Irrigation Department (RID) and other agencies. As of 2018 the district has five working reservoirs, a sixth in the planning stage, and Vajiralongkorn has ascended to the throne of Thailand.

## Geography

Neighboring districts are (from the west clockwise) Ban Kha, Chom Bueng, Mueang Ratchaburi, and Wat Phleng of Ratchaburi Province; Amphawa of Samut Songkhram province; and Khao Yoi and Nong Ya Plong of Phetchaburi province.
