Definition
1. Uninterrupted flow, if the water in the drain/gutter flows smoothly so that the water in the drains/gutters is moving, including here if the drains do not have water (dry).
2. Flooded, if the water in the drain/gutter cannot flow among others due to solid waste blockage or the flow is blocked as the subsequent channel is also stagnant (full), or there is no ditch/gutter.
3. Slow flow, if the water in the drain/gutter flows very slowly, among others due to the amount of blocked waste (solid waste) disposed to the drain/gutter, or caused by bad drain/gutter.
4. No sewer, if around the house there is no drain/gutter.
