Mueang Samut Prakan District, Thailand – Thai villagers in cooperation with community leaders have made bio-fermented water to solve the
issue of rotten water in natural canals that smell bad.

The bio-fermented water can be made by bringing leftover food waste from daily consumption to be mixed with molasses and emulsified
liquid and then left to ferment under natural anaerobic conditions for 15 days.

After that villagers pour the bio-fermented water into the canals to help add oxygen and improve the conditions of the water in the canals
that will become clean.

Villagers in Mueang Samut Prakan District said the bio-fermented water can be used for working in agriculture, fish farming, and watering plants
as in the past.

Bancha Munthongkham, head of the Bang Duan subdistrict, explained that they mix the leftovers with approximately 1 kg of different kinds of
fruits, 1 liter of molasses, and 1 liter of emulsifier.

“It is important to note that the lid must be covered and stirred with a spatula every two days to prevent gas build-up in the tank,” he added.
The bio-fermented water formula varies across different regions, according to Munthongkham.

A group of villagers and volunteers launched this campaign to help treat wastewater and make canals clean again as they were 50 years
ago, according to one of the villagers.

They took action after water in canals turned black and was polluted affecting the aquatic life in the area.

Also, bio-fermented water helps in treating ponds and fish farm water with microorganisms to increase the oxygen in the water.

Chatri Nimsuk, a villager in Mueang Samut Prakan District, referred to the existence of factories that release wastewater into canals as a
the major challenge they face, urging people to help preserve the environment.
