It is generally preferred to have a septic tank installed in a way that allows for gravity discharge rather than uphill installation. When a septic tank needs to be installed uphill, a pump station or chamber is required to push the water uphill. This adds additional cost and maintenance as the mechanical pump in the chamber needs to be serviced and monitored. If the pump fails, there can be a backup of foul water. Most manufacturers offer pumping station options, but it’s important to consider the ongoing maintenance and servicing requirements.
