EXCRETA DRAINAGE SYSTEM BSCE 1-1 – Group 3 Cato, Luigi E. Clarin, Kelly Patrick V. Dajac, Jobelle S. De Villa, Christian Angelo N.
DEFINITION OF TERMS ■ waste matter discharged from the body, especially feces and urine EXCRETA DRAINAGE SYSTEM ■ drainage pipes of a plumbing system taking the waste water from the plumbing fixtures and delivering it to the sewer or some other outlet ■ includes all of the piping within a private or public property that conveys sewage, rainwater, and other liquid waste to a point of disposal
Septic System ■ highly efficient, self-contained, underground wastewater treatment system ■ often more economical than centralized sewer systems in rural areas where lot sizes are larger ■ simple in design (less expensive to install and maintain) ■ less disruptive to the environment
Septic System SIX MAIN PARTS ■ sewer pipe from house to septic tank ■ septic tank to settle solids and suspend oils ■ sewer pipe from tank to distribution box ■ distribution box to evenly distribute flows to each leg of leach field pipe ■ leach field to drain the effluent water into the soil ■ soil to receive the effluent
HOW DO SEPTIC SYSTEMS WORK?
How do septic systems work? ■ Septic system receives wastewater from the house. ■ Sewer pipe drains to the septic tank. ■ Septic tank separates solids from the wastewater, stores and partially decomposes as much solid material as possible, while allowing the liquid effluent to go to the drain field.
How do septic systems work? ■ Biological growth occurs when the effluent drains into the soil. A biological mat grows on the soil that receives the effluent. This biological mat is important as it functions to treat the effluent.
