Inspecting the finished product is an important part of the installation process; this ensures the work was performed correctly (indicating the system should function adequately) and was installed in the specified location. The Virginia Department of Health (VDH) requires documentation of septic installation inspections, as well as, a inspection report and as-built drawing from the system designer and a completion statement from the septic system installer.
Similarly, VDH requires documentation of private well installations and a well driller’s completion report, known as a GW-2. For drinking water wells, VDH will also require a bacteriological water sample to be collected once the plumbing within the structure has been assembled. After receiving all the necessary documentation for the well and septic system installations, the local Health Department will issue an Operations Permit (OP) for each of the systems. Many counties require Ops from the Health Department before they will issue a Certificate of Occupancy or Occupancy Certificate.
Occasionally, septic inspections are needed in order to establish the capacity and condition of an existing septic system. This service is commonly requested when the existing septic system is planned to serve a proposed redevelopment, such as when one dwelling is razed so that another may be constructed in its place. The local Health Department may only require an inspection report, but the process would entail a building permit application to the county. As part of the inspection process, any deteriorated system components can be identified and replaced by a septic service provider.
