PARK SANITATION 



853 



The suggestions presented in the following pages apply particularly 

 to areas where it is not possible to connect with a community water and 

 sewer system such as in outlying parks and reservations, and camps, picnic 

 places, restaurants, inns, clubhouses, etc., therein. In any case the instal- 

 lation should be done by a competent engineer. The size of the sewer 

 pipe or pipes, the number and 

 location of the manholes, the 

 grade of the sewer lines will de- 

 pend upon and be modified by 

 the volume of sewage to be trans- 

 ported, the topography of the 

 terrain, and to some extent by 

 the method of ultimate disposal. 

 Where only a few buildings are 

 to be connected with sewers the 

 installation of a water carriage 

 system ordinarily presents no 

 great difficulty. In organized 

 camps, tourists' camps, inns, 

 etc., the sewage will consist of 

 waste from the toilets, kitchens, 

 baths, lavatories. The plumb- 

 ing fixtures should connect with 

 a soil pipe, which is a two or 

 four-inch cast-iron pipe extend- 

 ing from the house-connection 

 up through the roof and receiv- 

 ing the wastes from the toilets 

 and other fixtures. The soil pipe 

 also provides ventilation for the 

 house-connection sewer and 

 fixtures. 



The house-connection is the 

 sewer which receives the sewage 

 from the soil pipe. It should be 

 six inches in diameter and may consist of vitrified salt-glazed clay or cast- 

 iron pipe. The house-connection should be water-tight to prevent the entrance 

 of storm water, and if vitrified clay pipe is used the joints should be cemented. 

 If only one building is connected with the sewerage system or if each build- 

 ing is provided with a septic tank, the six-inch house-connection is carried 

 to the point of disposal or treatment. If more than one building is to be
