.... 1. Describe gray water and black water. 2. Describe the constituents of wastewater. 3. Describe preliminary, primary, secondary, or tertiary wastewater treatment processes. 4. Describe where OSST systems are used. 5. Describe the components of a septic tank. 6. Describe the differences between a septic tank and aerobic tank. 7. Why do most codes set minimum distances between the parts of the sewage system and wells and streams? 8. How is the ability of the soil to absorb wastewater determined? 9. Why should the designer consider not connecting pipes carrying certain wastewater (such as water from dish washing machines) to the private OSST system? Design Exercises 10. Draw a sketch of the major parts of an individual OSST system (septic tank and absorption field) in relation to a residence. Show clearance and setback requirements. 11. Design a private sewage system (septic tank and disposal field) for the apartment building. In this design, use a percolation rate of 16 min. 12. Design a private sewage system (seepage pits) for the apartment building. In this design, use a percolation rate of 16 min. Assume the maximum water table elevation is 2 ft (0.6 m) below grade. 13. Design a private sewage system (septic tank and disposal field) for the building. In this design, use a percolation rate of 22 min. 14. Design a private sewage system (septic tank and disposal field) for the building. In this design, use a percolation rate of 32 min.
