Epsom. Waterworks, New well. 1889. 



In the same yard as the older wells, but nearer the road 

 (between the. stables and East Street). 



A boring of 18 inches diameter, made and communicated by 

 Messrs. Tilley ; with some particulars from a Report to the 

 Local Board, by Mr. G. Hodson (1894). 



When made this bore-hole was tested to 13,000 gallons an 

 hour; but it is said that 20,000 gallons an hour are regularly 

 pumped, and that once this quantity was got continuously for 

 42 hours, when the flow of water was still enough to gain on the 

 pumps. The supply of the town is now chiefly got from this 

 boring.
