Air shall be forced into the system until there is uniform pressure of five (5) pounds per square inch in the section befng tested. The system shall be considered satisfactorily air tested if the pressure therein remains constaflt for fifteen (15) minutes without the addition of air. 4. The portions of any buried sewer more than fifty (50) feet from a well shall be constructed of cast iron, vitrified clay, cement-asbestos, concrete, or other approved pipe material. 5.

Lines shall provide a grade of not less than one-eighth (1/8) inch per foot. Where building sewers exceed fifty (50) feet in length, lines shall provide a grade which will allow a flow velocity of not less than two (2) feet per second. In no case shall the grade exceed two percent (2.0%). Ail changes of grade shall be by means of long sweep ells. Where long sweep ells are not used and where the direction changes by more than twenty and one-half (22-1/2) degrees, accessib]e watertight cleanouts shall be provided. 150.014C SEPTIC TANKS Subd. 1 GENERAL All tanks, regardless of material or method of construction, shall be: a.

So designed and constructed as to withstand a mini- mum of seven (7) feet of saturated earth cover above the tank top; e. Not subject to excessive corrosion or decay. StUd. 2 I)ESI GN All tanks, regardless of material or method of construction, shall conform to the roi. lowing design criteria. ]..

No tank or compartment thereof shall have an inside horizontal dimension less than twenty-four (24) inches.
