Rainy-season flooding that has plagued Naklua’s Ton Krabok neighborhood for a decade may finally come to an end next month as workers complete a 10 million baht overhaul of the Sukhumvit area’s streets and drains.

Deputy Mayor Wutisak Rermkitkarn and top Sanitation Engineering Department staffers inspected work being done by a private contactor on Soi Sukhumvit Soi 28 and the connecting 5, 7 and 9 sub-sois. Installation of a new drainage pipe, steel-reinforcement of roads and the digging of a flood-runoff reservoir are scheduled to be complete by the end of January.

A new drainage system on sois 5, 7 and 9 in Naklua’s Ton Krabok neighborhood will cost the city about 3 million baht each. A new drainage system on sois 5, 7 and 9 in Naklua’s Ton Krabok neighborhood will cost the city about 3 million baht each.

Channarong Plomnee, of contractor Maalithong Co., said the reason Ton Krabok floods every rainy season is that the top of Soi 28 is about three meters higher than the bottom of the soi. During heavy rains, water runs down the street and pools at the bottom and on the smaller sub-sois, reaching depths as deep as 60 centimeters.

Wutisak said new pipes on sois 5, 7 and 9 cost the city about 3 million baht each. He also acknowledged the problem has been known about for around 10 years.

A key part of the project will be the reservoir, which will be able to hold about 68 cu. meters of runoff. At the same time, pumps in the pool will reverse the water behind Soi Sukhumvit 28.
