Water Supply and Drainage 



233 



The well which is sunk through pervious strata should have a tight wall to 

 the depth of the outlet of supply. Often brick is substituted for stone, such 

 being laid fairly thick say 12 inches at the least. It is doubtful if it has any 

 other advantage over stone than that of presenting a smoother surface; hence it is 

 easier to clean. As this last consideration is of considerable importance, the brick- 

 lined wall is worthy of consideration. 



In the case of all wells the masonry should be carried above the grade, to 

 allow for the making of a slight pitch away from it to shed the immediate surface 

 water. Nor should there be any permanent woodwork inside a well; its tendency 

 is to attract and shelter animal life, as well as to affect the water by decay. A 

 well is usually round in construction; this form, receiving the equal pressure of 

 the soil on all sides, is less liable to collapse than any other form. Wells should 

 be covered to protect them from falling refuse and dust, but they should at the 

 same time have ample ventilation. 



It is impossible to give any hard-and-fast rules to govern the locating of a 

 well, but, as already stated, it is an advantage to have it on as high ground as 

 may be practical, that the danger from surface inflow and substrata infection may 

 be lessened. If your 

 neighbour possesses 

 a good well, some- 

 thing may be learned 

 from that, perhaps, 

 and if it be located 

 near your line and 

 water is plentiful, it 

 is not a bad idea to 

 locate near it. Some- 

 times a spring in 

 close proximity to 

 your land, either 

 above or below it, 

 may be intercepted 

 by a well. In such a 

 case, if the water be 

 good, your problem 

 is solved. If there be 

 no visible evidence 

 to go by, the only 

 thing to do is to steer 

 clear of neighbour- 

 ing cesspools and 

 dig. The chances 

 are that you will 

 strike good water.
