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.

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.
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.
