Jomtien crews clear a clogged drainage line after heavy rain

July 6, 2026Event date

The work was under way in front of Yaimak Market when acting mayor Kiattisak Sriwongchai inspected the site with Pattaya City engineering staff. The response followed flooding around the Jomtien beach area after heavy rainfall.

About 90 cm of sediment was restricting the flow

Officials said the affected drainage pipes were roughly two metres deep and contained around 90 centimetres of accumulated silt and dirt. That left considerably less space for stormwater to move through the line and was identified as one factor contributing to the local flooding.

The distinction matters. This was maintenance of an existing drainage route, not the installation of a new flood-control system. Clearing the sediment can restore capacity in the pipe, but it does not establish that every cause of flooding in Jomtien has been addressed.

For practical context, see Living in Thailand. This development also connects with Chonburi floods prompt evacuations and boat restrictions.

Crews were assigned to a line nearly two kilometres long

The city ordered dredging along the affected line toward Nong Phrong, a stretch reported to be almost two kilometres. At the time, officials expected the operation to take about three days.

That was a projected work period instead of proof that the full section was subsequently completed on schedule. Available follow-up reporting does not confirm that the entire section was completed on that timetable. The accurate description is therefore that urgent dredging began, with a roughly three-day target announced at the time.

For people living or running businesses nearby, the immediate effect was practical rather than dramatic: maintenance vehicles, work around the road and possible short-term access disruption. If sediment was the main obstruction in that pipe, removing it should improve the line's ability to carry water during later rain.

Drain maintenance improves capacity but does not remove flood risk

A cleaned pipe can still be overwhelmed by intense rainfall or by bottlenecks elsewhere in the network. Local topography, downstream capacity and the condition of adjoining drains all affect how quickly water leaves a street.

Heavy rain again flooded several low-lying roads elsewhere in Pattaya on September 10–11. That later report did not identify the Yaimak Market line, so it does not show that the July work failed or remained unfinished. It does, however, underline the broader limitation: one maintenance operation should not be taken as a citywide or permanent solution to flooding.

For someone considering a long-term home in Jomtien, a more useful check is how the exact access road and surrounding low points behave after several heavy storms, instead of assuming the whole district has the same drainage performance.
