PARK SANITATION

or one of the more elaborate wall types may be installed. If the sanitary 

 privy is used it will be found more satisfactory to separate as much of the 

 urine as possible from the feces by means of a urinal connected with a soak- 

 age pit. If for any reason a soakage pit cannot be used in connection with a 

 sanitary privy, and the feces are to be burned or buried, the urine should 

 be collected in one or more receptacles (pails) separate from the feces, as 

 urine interferes markedly with the incineration of feces and also increases 

 the difficulty incident to burial in trenches or pits. 



The urinal in a L. R. S. privy should drain into the liquefying tank 

 (Plate 323). In the pit privy the urinal, as a rule, empties directly into the 

 pit (Plate 328), or it may, in the case of water-tight vaults, be connected 

 with a soakage pit. Where flush toilets are used the urinals are connected 

 with the sewer. 



Soakage pits. A very efficient soakage pit consists of a pit from four 

 to eight feet square by four to ten feet deep, filled with broken rock to within 

 six to twelve inches of the top (Plate 345). Above the rock is placed a layer 

 of straw, matting or burlap, and the pit is then filled to the top with sand.
