The community's public health officers and volunteers travel by local boat along the canal to visit different households living along the canal.
Along the sides of most canals and the Chao Phraya river are places for social, religious and cultural activities such as temples, markets, hospitals and government offices. Samrong canal in the Samut Prakan province is connected to the lower part of the Chao Phraya river. The upper part of the canal is home for thousands of families who uses the water for their livelihoods, such as fishery, aquaculture, agriculture, transportation, and daily domestic use such as cleaning and washing. The water quality deteriorates as it travels downstream.
