PRACTICAL LANDSCAPE GARDENING 



WATER SUPPLY .\ND DR,-UNAGE 



The pool should be connected with the general water supph", if 

 practicable, and a drain provided (Fig. 141) so that the pool may 

 easily be emptied, cleaned and retailed. The most economical and 

 practical method to arrange for the overflow and drainage is to 

 have a standpipe with a ground beveled end to fit in a socket set at 

 the low point of the pool. The size of the pipe will depend on the 

 amount of water, but, for ordinary purposes, a one and one-half inch 

 pipe is sufficient to carry ofi the overflow. To drain the pool it is 

 only necessary to remove the standpipe. 

 Another method of pro\'iding for the 

 overflow and drainage is to have a con- 

 cealed standpipe (Fig. 142) built into 

 the end wall of the pool, ^\^len the 

 water rises to the top of the standpipe 

 at A, it overflows. To drain, the stand- 

 pipe is remo\'ed through a concealed 

 opening at B. 



Where the drain is controlled by a 

 valve, the valve should be set in a 

 smaU box with an iron co^-er set flush 

 with the grade. 



From a point immediately outside 

 the waUs of the pool the water may be 

 carried ofi by a three-inch terra cotta 

 pipe. 



The appearance of the pool will be 

 greatly improved by placing an inch of 

 clean pebbles over the bottom.

G.\RDEN POOLS WITH FOUXTAIX HE-VDS 



Oftentimes garden pools are placed at the ends of the gardens 

 fed from a fountain head placed in a vertical waU. 



The construction of such pools should be similar to that ahead}' 

 outlined. 



The vertical wall should rise abo\-e the wall enclosing the garden 

 to emphasize the feature. 



Fountains and pools so located should be provided with a good 

 background, preferably evergreens of a dark shade; the Red Cedar 

 and similar types are admirable for the purpose.
