Plant Life in Nepali Culture

My study revealed that I could use two main types of filtration in the river itself: plants and sand filtration. Plants have a special place in Nepali culture. They are used in daily offerings to the gods and as a part of religious rituals. Eco-friendly plants, particularly those that use little water or serve as water-purifying filters could be planted in wetlands adjacent to the river banks in order to filter the water, while at the same time removing bacteria and pollution. The challenge was to make such progressive steps culturally desirable so that they become integrated into daily activities.

 

Plant Filtration 

Wetland plant life such as cattails and bulrush has proven to be successful in cleansing and purifying polluted water.

Sand Filtration  

 
The second treatment could be a sand filtration process that is established in the bed of the river. Impurities could be extracted from water that flowed through three layers of gravel, arranged from large to small gravel. A wall separates the dirty water from the clean water leading from filter to filter. As the water runs through new filters, the area for clean water is expanded to minimize the bacteria in the water.
