Fic. 2649. Sewage Disposal Works at Hamilton, Ont. 



AN IMPORTANT PHASE OF CIVIC IMPROVEMENT. 



ABOUT eight years ago Hamilton un- 

 dertook to solve the sewage disposal 

 problem by building an elaborate system of 

 interception works to prevent the pollution 

 of the waters of Hamilton Bay. 



The sewerage system of the city is one of 

 the most complete to be found anywhere. 

 There are about 35^ miles of main trunk 

 sewers and 49 miles of laterals or small ser- 

 vice sewers. By means of the trunk sew- 

 ers the cit-^' is divided into three districts for 

 sewer purposes. The sewage from the 

 easterly district tiows to the Wentworth 

 street disposal works, that from the center 

 to the Ferguson avenue works, and that 

 from the westerly district into the marsh 

 land lying between the city limits and Dun- 

 das. Already provision has been made for 



a third disposal works in the westerly dis- 

 trict, and when these are in operation there 

 will be nothing but a clear water flow into 

 Hamilton Bay. 



The disposal works now in operation, 

 which handle the great bulk of the city's 

 sewage, are the first to be erected in Canada. 

 They were built in 1896, and are of the well 

 known chemical precipitation sort. The 

 effluent or clear water flow from these 

 works, after the solids from the sewage have 

 been extracted, flows into the bay. The 

 solids are pressed into a stifif, clay-like 

 sludge, which is used by farmers for ferti- 

 lising purposes. The cost of operating the 

 two works now in operation is about $13,000 

 a ^ear.
