LEACHING TILE FIELD AND HOUSE SEWERS 4.1 Septic Tank 4.1.1 Design Capacity The septic tank capacity may be determined from the quantities of sewage flow contained in Table 1 Chapter XVII of the Code on Sanitation of the Philippines (see Annex), based on ad equate detention time interval resulting in efficient sedimenta tion. Daily flow from metered water consumption may be used to estimate flow when available. For buildings with occupants, the number of persons to be served shall be computed based on the number of rooms and considering each room as occupied by two persons or on the basis of the actual number of persons served by the tank, whichever is the greater. Tanks constructed in series may be used to accomplish the re quired capacity provided the first tank will fumish · at least half of the required capacity. This capacity requirement allows for the use of all household appliances inclucling garbage grinders and automatic washers. 4.1.2 Inlet and outlet a. The invert level of the inlet shall not be less than 5 centimeters (2 inches) above the liquid level of the tank. b. A vented inlet baffle or sanitary tee shall be provide to divert the incoming sewage downward. The baffles or tee shall pen etrate at least 15 cm. (6 inches) below the liquid level, but the penetration shall not be greater than that allowed for the outlets baffle or sarùtary tee. c. The outlet shall be fitted with a sanitary tee or baffle. d. The outlet baffle or sanitary tee device shall extend through the scum layer above the liquid level of the tank to approximately 2.5 cm. (1 inch) from the inside top from the tank. e.

Septic tanks shall be Jocated such that desludging equiprnent can have access to the opening manholes conveniently. c. Septic tanks shall not be located under the building. 4.1.7 Maintenance a. Septic tanks shall be cleaned before excessive sludge or scum is . allowed to accumulate and seriously reduce the settling effi.ciency. b. Septic tanks shall be inspected at least onœ a year and be cleaned when the bottom of the scum matis witlùn 7.50 ( 3 inches) of the bottom of the outlet device or the sludge and scum has reduced the Iiquid capacity by 50%. c. Tanks shall not be washed or disinfected after cleaning. A small residual of sludge shall be left in the tank for seeding purposes. d.
