Drain field systems treat home sewage, whereas septic systems are self-contained tanks. Tanks, pipes, and absorption zones make up this structure. Maybe you've found the perfect spot in your yard for pavers, but a septic tank is there. Can you put pavers over the septic tank? We have an answer for you based on our research.
You should not put patio pavers over a septic tank. Doing so may violate local or state zoning restrictions. Septic tanks cannot sustain heavy weight. Putting too much weight on them may cause damage.
Covering a septic tank with pavers could lead to problems because you'll probably need to access the tank in the future to monitor or maintain it. Building standards have specific criteria for the installation and maintenance of septic systems. Continue reading to learn the rules and regulations for septic tanks. We will cover this subject in further detail below.
Should You Pave Over A Septic Tank?
Paving is restricted over a septic tank to safeguard the system. This is due to the volume and weight your tank can support. Your septic tank should be easy to access, ideally without requiring you to remove any pavers.
It is not a good idea to pave over a sewage tank. This includes paving for a driveway, a porch, or a tennis court. In addition to preventing direct runoff, concrete adds a substantial amount of weight, which could lead to the collapse of the pipes in the septic field.
Other Septic System Considerations
Here are some factors to consider for your sewage system.
The two most typical types of vegetation that cannot be grown on a septic field are shrubs and edible vegetable plants.
Even if a vegetable garden is aesthetically beautiful, harmful microorganisms can contaminate food if plant roots consume them. A raised garden is also not a good idea because the extra weight of the soil and bed supports may damage the sewage pipes.
Do Not Build
You should not install a structure over a septic field. Decks are too heavy to be put securely over a septic field. They also obstruct system access while inhibiting the establishment of grass and other beneficial flora that decrease the adverse effects of erosion.
Do Not Plant Trees
Trees and other plants with broad or deep root systems might impede septic system operation. These plants may even wrap the septic field's pipes, trapping sewage and causing flooding.
It's not surprising that these plants can compress septic system pipes because massive tree roots, in particular, are infamous for having enormous root systems that can pierce rock, pavement, and even house foundations.
Don't Set Up Play Structures
Large play structures are sometimes massive, putting pressure on the septic field and raising the risk of pipes bursting or bending just a foot or below the surface. Some playground equipment can block evapotranspiration, leading to flooding and field erosion.
Pools Are Not Permissible
Considering that in-ground pools should be dug up and built near sewage lines, this is a clear obstacle. Above-ground pools can also be problematic. Swimming pools can compress pipes, clogging the septic system and preventing oxygen from entering the sewage pipes.
