A __________ is a chamber made of concrete, fiberglass, PVC or plastic, through which domestic wastewater, sewage flows for primary treatment.(a) drainage tank(b) pit latrine tank(c) harvesting water tank(d) septic tankThe question was posed to me at a job interview.My question is taken from Design of Septic Tanks in division Road Estimating, Sanitary and Water Supply Work of Civil Engineering Drawing
Answer» RIGHT choice is (d) septic tank Easiest explanation: Septic tank systems are a type of onsite sewage facility (OSSF). They can be used in areas that are not connected to a SEWERAGE system, such as rural areas. The treated liquid effluent is commonly disposed in a septic DRAIN field which PROVIDES further treatment.
