Sometimes a homeowner may make removable boards or trap doors that lead under a deck to their septic tank lid for access to pump the tank. Most of the time, this happens because the homeowner is unaware of the tank location and/or does not plan for future maintenance on their tank. It is not uncommon for us to find tanks located under a wooden deck, pool patio, driveways, or even room additions.

The most common problem we see is when someone wants to pump out their septic tank but doesn’t know where their tank is located. It is never recommended to build a structure over any portion of your septic system. This can lead to greater expenses when finding and servicing the system. Some homeowners, whether accidentally or deliberately, build items like patio decks or home extensions over their systems.

These setback requirements include distances from the septic tank and the drainfield from foundations, pools, property lines, water wells, etc. Minimum setback requirements established by The Texas Commission on Environmental Equality (TCEQ) usually prevent initial house construction from occurring over any point of a septic system.
