R.H. Murray School in Whitefish is using an advanced wastewater system to treat its waste more efficiently. At the same time it is protecting nearby groundwater and streams, said Terry Luck, wastewater representative for Bionest Distribution Inc., based in Pembroke.
The $100,000-plus system was installed Monday. The company has installed 300 similar systems in southern Ontario, 6,000 in Quebec and 200 in Western Canada, said Luck.
Peter Firla, environmental engineer with Trow Associates, designer of the Whitefish installation, said the school needed a new wastewater system to replace the use of a sewage lagoon it has been using since the 1960s.
“The school has concerns over liability, mosquitoes, odour and illegal dumping regarding the lagoon and they wanted a new system designed and installed,” said Firla. The clay soil on site did not offer the proper percolation rate for a standard septic system, he said.
Because a commercial sized septic and field bed system requires a lot of space, the school asked Trow to come up with a smaller sized system.
“We had just investigated a system for a client locally using the Bionest technology and went with that.”
Between the standard-sized 25 cubic metre septic tank and the field bed, is a 15 cubic metre unit that measures 1.5 metres high, two metres wide and 4.5 metres long. The unit is called a Bionest wastewater treatment system.
The system will operate more efficiently over a longer period of time and requires less space on the site, said Firla.
The downsized field bed that can handle 10,000 litres per day is sized at 30 metres by 30 metres.
“A smaller field bed means less excavation, less aggregate used and less space (is) required,” said Firla.
The wastewater leaving the field bed is cleaner than that of a conventional septic system process. This is important because the liquid eventually seeps into ground water or ends up in nearby water bodies.
“The wastewater will have a lower BOD (biological oxygen demand) going into adjacent water bodies. It will tie up much less oxygen that is required by fish or other life,” he said.
Firla said he would recommend the system to other clients in the north. For more information about the system, go to www.bionest.ca
