Combined Overflow Wastewater Catchment Areas

The drainage area (subcatchment) for each individual length of combined sewer in Hamilton.

The City of Hamilton has a large complex wastewater collection network consisting of both separated sewer and combined sewer systems:
  • Modern areas of Hamilton have separated sewer systems. 
  • In older areas of Hamilton, a combined sewer system collects both storm water (rainwater or melt water), and wastewater in the same pipe. During periods of heavy rainfall or snowmelt, combined sewers are inundated with large volumes of storm water that can exceed the capacity of the pipes.
