Fig. 12.— A good outlet should be provided for every main drainage line. The tile should 

 follow the low ground, about three feet below the surface, and the end should open into 

 a ditch or sewer two feet above the mean water level to prevent backing up and flooding 



The narrow ditch is dug with the bottom even so that the tiles 

 can be laid securely. They must be laid or fitted tightly together, 

 end to end, but not cemented or joined in any way. The result desired 

 is that water will filter in through the joints, although soil cannot 

 enter to clog the drain. A fall of approximately six inches in 100 feet 

 will carry off all surplus water, and even less than this will serve the 

 purpose, providing the drain is laid correctly. Laying a drain with 



only a very slight 

 inclination is a task 

 for a skilled engineer 

 and is best left to 

 such as are capable 

 and experienced in 

 these matters. 



A line of tile laid 

 at the bottom of 

 the cellar foundation 

 will carry oflf water 

 that might otherwise 

 seep through the 

 walls(Fig.3).Where 

 there is only a small 

 amount of surface 

 water to take care 

 of, a dry well can be 

 easily constructed, 

 sufficiently large to 

 handle the surplus.
