CHEMICALS: Onsite vs. Pipeline (& ROPEC):

ONSITE TREATMENT:

The onsite treatment plant employs the use of a rather inert material, alum, to assist, in the (Dynasand) Phosphorus removal process. With the use of UV-treatment to disinfect the final wastewater, avoidance of the use of environmentally toxic Chlorine can be achieved. This is a huge environmental plus!

PIPELINE and ROPEC: (Not shown in pipeline section of flyer)

ROPEC, on the other hand, pours vast amount of Chlorine into the Ottawa River, and has received ever reducing grades in the Sierra Legal's grading, in the Canadian Cities Wastewater Treatment Report Card (CLICK HERE).

Forcemains, over distances of only 5 miles (approximate) very quickly develop toxic Hydrogen Sulphide (H2S)-gas, and Methane, which are vented to the environment along the route as the sewage goes "septic". To help mitigate this, chemicals like ferrous chloride are extensively used, and injected at various points along the pipeline route.
