Meehan. — An Aqua7'ium for Philadelphia 181 



regions for conveying mine water impregnated with sul- 

 phur. 



The sea water house abuts directly on the Fairmount 

 Dam. Owing to the liability of floods from the Schuyl- 

 kill River it was necessary to raise the floor above the 

 ordinary flood level ; therefore in that building there will 

 be but one set of tanks. The fresh water house will have 

 a second tier of tanks making the capacity of that build- 

 ing 110 tanks of large size.
