Firm annotation
The elements are (1) an act by any means, (2) done in order to cause a flood or to obstruct the use of water that is a public utility, and (3) the act being likely to endanger another person or another person's property. The purpose element matters: the section requires that the act be done in order to bring about the flood or the obstruction, so flooding caused accidentally or by negligence falls outside it. Paragraph one is satisfied by likely danger alone, and where danger to a person or to property actually results the penalty rises. This section is about water as a resource and a hazard. Interference with a lighthouse, buoy or other safety signal for land traffic, navigation or aviation is dealt with separately by Section 231, and putting a public way, floodgate, weir or dam into a condition likely to endanger traffic is Section 229.
Why this matters in practice
The purpose element is what most cases turn on. Section 228 requires that the act be done in order to cause a flood or to obstruct a public water supply, so a contractor whose works flood a neighbouring plot through carelessness is not caught by this section, and the dispute belongs in tort under Section 420 of the Civil and Commercial Code instead. Where the intent is present, exposure is serious and rises sharply once real danger results. The provision is often relevant to irrigation disputes, blocked canals and interference with a village water supply, and a complainant should preserve evidence of the deliberate act, such as a diverted channel or a closed sluice, rather than only the resulting damage.

Frequently asked questions
What does Section 228 protect?
The public water supply and the safety of people and property from deliberate flooding. It punishes doing anything in order to cause a flood, or to obstruct the use of water which is a public utility, where the act is likely to endanger another person or another person's property.
Does accidental flooding fall under Section 228?
No. The section requires that the act be done in order to cause the flood or the obstruction. Flooding caused by carelessness is not this offence, and the claim belongs in tort under Section 420 of the Civil and Commercial Code instead.
What is the penalty under Section 228?
Imprisonment of up to five years, or a fine of up to 100,000 baht, or both. Where the act actually causes danger to a person or to property, the penalty rises to six months to seven years with a fine.
