A 6-inchwell passes through 40 feet of clay and sand and ends with a 6-footstrainer in a bed of gravel from which the water rises to a level12 feet below the surface. According to estimates made the maxi-mum yield does not greatly exceed 20 gallons a minute. The water isreported somewhat hard but otherwise good. It is stored in two com-pression tanks, from which it is de
