MODERN METHODS OF STREET CLEANING 



tion with the flushing of street surfaces a number of 

 watering-carts with horses and four motor water wagons 

 are used to thoroughly water the surfaces of the streets 

 to be flushed. 



The water is obtained for the most part through 

 metered hydrants placed below the surface of the side- 

 walks. Otherwise the water is supplied by a turncock 

 who accompanies the flushers by previous arrange- 

 ment with the Metropolitan Water Board. The time 

 occupied in flushing with each f-inch nozzle is recorded 

 by the turncock and charged for at the rate of $1.25 

 per hour. Since 1902 meters have been placed in con- 

 nection with many of the hydrants, the price charged 

 for the water being about 12 cents per thousand gallons. 

 At the present time there are about 612 metered hydrants 

 in use. The streets are flushed from once to six times 

 per week, depending upon the amount of vehicular 

 travel. 



No flushing is carried on when the temperature is 

 lower than 36 F., or when the condition of the street 

 surface renders the work manifestly unnecessary or 

 undesirable. 



When not engaged in flushing or cleansing with 

 water the night staff with horse-sweeping machines 

 and sweeping machines attached to motors are engaged 

 in cleaning thoroughfares. No Sunday flushing is done 

 after 8 o'clock A.M. 



The scattering of sand upon the street to prevent 

 slipping is carried on between 5:30 and 8 P.M. by men 

 sanding of especially suited to this duty. They are 

 Pavements supervised by four foremen who, for the 

 control of this work, have their districts planned so 

 that all of the streets which are sanded are divided
