Non Point Source Pollution Reduction
Non Point Source Pollution Reduction
Non Point Source Reduction Project
The Non Point Source (NPS) refers to the source of emission where the water pollutants are discharged in an unspecified manner from the unspecified places such as cities, roads, agricultural fields, mountainous areas and construction site. In this regard, K-eco installs the Non Point Source Monitoring Center to manage the NPS appropriately.
Non Point Source Reduction in Urban Areas
To handle the NPS generated from the residential, commercial and industrial areas, the ecological retention sites and the ecological parking lots are installed while the infiltration trenches and retention ponds are built by the roads. In the meantime, the large-scale equipment-type facilities are installed in the industrial areas.
Non Point Source Reduction in Rural Areas
To handle the fertilizer, agrochemicals, muddy water, and manure washed off by rainwater from the agricultural and livestock houses, the constructed wetlands of high efficiency are installed.
