In British Columbia, an onsite wastewater system must be designed by a Registered Onsite Wastewater Practitioner (ROWP), and the design must be filed with the regional health authority — Interior Health here in the Okanagan — before installation.

No wipes (even ones labelled "flushable"), grease or cooking oil, paint, solvents, harsh chemicals, medications, or feminine hygiene products. These clog pipes, kill the beneficial bacteria your system depends on, or overload the drain field.
