Facts About Sewage
Sewage poses a very significant threat to human health. Any time sewage is suspected, no matter the color of the water, all suitable precautions should be observed. The severity will depend upon extent, content and degree of penetration. The health of technicians and occupants must take priority over all other considerations. Sewage situations may be classified into three categories according to extent, content and degree of penetration. The first situation exemplifies very little waste that originates in the built environment and is deposited or flows slightly beyond the confines of the sewage system. An example of this situation might be waste that overflows in a bathroom and is deposited on a tile floor. The second situation is where the water and waste penetrates the structure or furnishing of the building. An example of this situation is when flooding occurs in the fourth floor men's room of an office building, flows under a wall and into the carpet of an adjacent hall. The third situation is when waste has entered and mixed with other wastes from outside the immediate environment. The main line of the sewage system is backed up into the built environment where it is widely dispersed and penetrates the structure and the furnishings of the built environment.
