THE HOME WATER SUPPLY 57 



HOME PROJECT 7 



Purpose. To read the water meter and compute the weekly 

 cost of water. 



Directions, i. If you have connections in your home with 

 a supply of running water, read your water meter. If you 

 have the straight reading register, copy the figures found there. 

 If you have a dial-reading register, make a drawing in your 

 notebook of your meter. Draw each circle, copying the figures, 

 and draw in the pointer in its proper place with reference to the 

 figures. Bring the drawing to school so that the teacher may 

 explain how to read the meter. 



2. One week later, make another reading and subtract the 

 first reading from the second. Find the price charged for water 

 and estimate the cost of one week's supply.
