OSI Onsite Systems Inc. is a Canadian-based company located on Vancouver Island specializing in innovative on-site wastewater system design for both commercial and residential applications.
We are dedicated to designing systems that are environmentally appropriate for the site, efficient and cost-effective. Our philosophy is that on-site systems are a respectable and in many ways environmentally superior wastewater option.
We are active in transferring onsite wastewater knowledge to B.C., both through our support for industry associations and through our many industry contacts in the Pacific Northwest who are regarded as leaders in onsite wastewater technology. We founded the B.C. Onsite Sewage Association (BCOSSA).
