Drain Design Research by Droycon Bioconcepts Inc. A First in Canada

Droycon Bioconcepts Inc. (DBI) recently played a key role in solving a major home construction problem in Quebec. The Regina-based microbiology and environmental technology company addressed the problem of ochrous plugging, or bacterial growth, in drains.

Dr. Roy Cullimore, Principal of DBI, explains that the problem has particularly occurred in the drains of new houses constructed in Quebec. ”The drains are meant to divert water away from the house. However, due to ochrous plugging, the drains fail, resulting in a high risk of flooding,“ says Dr. Cullimore.

Mainstream is assisting the Resort Village of Kannata Valley and the Village of Buena Vista to meet these guidelines. The company plans to carry out field tests in the two locations this year.

For the past three years, DBI has worked in coordination with the Home Warranty Program in Quebec to research the problem of ochrous plugging. Dr. Cullimore notes that the research is “the first of its kind in Canada.”

During the initial stages of the project, DBI focused on the detection and identification of the bacterial activity that has been plugging the drains. DBI followed this research by developing a new drain design that will significantly reduce ochrous plugging. With funding provided by CT, in addition to funds from the Home Warranty Program, the company tested drain models in a laboratory setting to determine the most effective drain design.

Based on DBI’s research and innovation, the Home Warranty Program in Quebec is currently establishing new construction regulations. Dr. Cullimore says that the ultimate goal of the research is to have the construction industry utilize the new drain models that are less prone to plugging.

Canada Mortgage and Housing Corporation (CMHC) is also recognizing DBI's research and drain design. “CMHC is currently working with the Quebec Home Warranty program to coordinate evaluations across Canada,” says Dr. Cullimore. He adds that CMHC is encouraging other provinces to follow Quebec's lead in the implementation of new construction methods for drains.

DBI plans to continue to research ochrous plugging for the next three years as part of the ongoing program to regenerate plugging drains and water wells. Dr. Cullimore explains the company will particularly focus on developing systems that will remove any bacterial plugging that occurs after the drain is installed.
