MANAGEMENT ASSOCIATION OF BC
Your system safely treats wastewater and returns it to the ground. Under Provincial Sewage System Regulation and ASTTBC's OWCB Policy, a sewage system can only be installed by an Authorized Person (ROWP Installer), or an owner constructing a sewage system on his or her own land, under the continuous supervision of an Authorized Person (ROWP Installer).
Where the ROWP Installer other than the ROWP Planner installs the system:
-The owner retains the ROWP Planner to review the installation for conformance with the drawings and specifications.
-The ROWP Installer provides the ROWP Planner with information on the installed system.
-The ROWP Planner files the final report with Interior Health.
Many factors, for example, the size of the house, the size of the lot, soil conditions, the slope of the land etc. determine the final cost of the septic system.
It is not possible to accurately estimate the cost of the septic system before the design process is completed.
Generally large houses on small lots often require secondary treatment plants and pressure distribution systems, resulting in significant cost increases. Poor soil permeability can be another factor. A shallow seasonal water table or non permeable layer like bedrock can require the system to be installed above ground (sand mound), which can cost significantly more than a simple in-ground gravity distribution system.
As a guideline, gravity distribution systems cost between 10,000-15,000+GST including soil testing and design, while the cost of a large sand mound Type II system can be significantly higher.
