Local wisdom in action

Experts have ideas on how to manage water, but so do ordinary people and some of their ideas can be put into action in almost no time. Here’s an example being used in Thonburi.

Local wisdom in action

The experts have ideas on how to manage water, but they are often expensive and they take can years to put into action.

Ordinary people have ideas too and they can be put into action in almost no time. They are usually small-scale ideas but every little bit helps.

The situation on the Thonburi side of the Chao Phraya river is especially desperate.  Pumps for draining water are scarce and Bangkok senator Rosana Tositrakul is promoting a bit of local wisdom as an alternative.

Bangkok Senator Rosana Tositrakul explains how water-push devices help speed up flood drainage in Khlong Ratchamontri in Bangkok’s Bang Bon district. PATIPAT JANTHONG

Since Oct 30, two "water-push devices" have been placed at a section of Khlong Ratchamontri in Bang Bon district to speed up water flow to the sea.

If at least nine more can be acquired, Ms Rosana hopes the floods can be better brought under control.

The device is made up of two connected, 200-litre containers with their bottoms sawn off.

They are attached under a motor boat moored to the Ekkachai-Bang Bon bridge, forming what Ms Rosana calls a "tunnel", which helps speed up water flow.

As the boat propellers spin, water is funnelled through the tunnel. This increases water pressure and causes it to flow quickly and forcefully. The devices also help increase canal depth.

Days after they were first put to use, Ms Rosana said, the depth has increased by more than 12 centimetres.

This is because when the water is pushed by the propellers, it helps dredge the canal bed, sweeping out rubbish and clay.

As a result, Khlong Ratchamontri can now hold more water than it did, which will help drain floodwater out of Thon Buri.
