Building Near and Over Septic Tanks

Posted on a regular basis In most cases, minimum setback rules imposed by the Texas Commission on Environmental Equality (TCEQ) preclude the building of a new residence from occuring over any point of an existing sewage disposal system. Foundations, pools, property lines, wells, and other structures must be kept at a certain distance from the septic tank and drainfield in order to meet these setback requirements. It is possible that some homeowners will install objects such as patio decks or house additions over their systems, whether by accident or design.

Building over septic tanks

Construction of a building over any section of your septic system is not recommended. The most typical issue we see is when someone wants to pump out their septic tank but is unsure of where their tank is situated on their property. Tanks hidden beneath a hardwood deck, pool patio, driveways, or even room extensions are not unusual for us to discover and investigate. The majority of the time, this occurs because the homeowner is uninformed of the tank’s location and/or does not have a plan in place for future tank maintenance.

However, in this scenario, the homeowner will be able to pump out their septic tank because no permanent constructions should be constructed over any component of the system.

Building over drainfields

In order for the drainfield to function, water in the solids and some evapotranspiration must be absorbed. In order for bacteria in the soil beneath a drainfield to treat wastewater from a drainfield, the soil beneath the drainfield must have sufficient oxygen. However, if a permanent structure is constructed over a drainfield, it has the potential to reduce the amount of oxygen that can be absorbed by the soil and hence reduce evapotranspiration. The potential of causing the drainfield lines to collapse is a significant concern when constructing over them.

Depending on the age of your system and the restrictions of your local authorities, repairing or shifting your drainfield may need the installation of a whole new system.

This is also true for people who are considering purchasing a property and intend to remodel it. It is preferable if you are aware of the exact location of your tank and drain field. This will prevent new construction projects from interfering with the normal maintenance of your system or causing damage to your septic tank. Before beginning on any big job that may include your septic system, make sure you have a solid understanding of septic systems under your belt.

Take a look at our ebook, which is provided below. It is an excellent resource that can help you feel much more confident about owning, maintaining, and renovating in close proximity to a septic system.

Building Near aSeptic Tank

What may possibly happen if you fail to locate your system? It is possible that your septic tank is in the route of a huge construction truck. It would be the least of your worries if your septic tank lid were to break. Cracks in the septic tank may be caused by the weight of building equipment on the site. It is possible that these will not be apparent soon after the event. Cracks will grow with time, however, and will pose a major structural threat over time. In most cases, a tank is clearly marked in some way to make it easier to locate.

  • This will guarantee that the driver is aware of the exact location of the tank and that the tank has enough space to move about.
  • In addition to causing damage to your tank, construction may prevent a pumper from entering the tank.
  • This not only makes it difficult to locate the tank, but it also makes it difficult, if not impossible, to maintain it.
  • If you have a deck or patio that prevents access to the tank, you may be forced to demolish the building, squandering the money you invested on its construction.

Building Near aDrain Field(Leach Field)

If a drainage field is destroyed, the expense of replacing it might be significantly higher. The most serious problem that might occur from building near a drain field is the damage that heavy construction equipment can inflict to the drain field. The weight of a large number of heavy trucks moving over a drain field will shatter the pipes in the drain field and compress the soils beneath the trucks. Compacted dirt in a drain field will impair the ability of the drain field to drain effectively.

Without any air pockets to fill, the effluent will be pushed to rise towards the surface of the soil, where it will eventually pour out onto the ground.

A few instances of how construction near a drain field might potentially result in a problem are shown below.

Problems Building Near a Drain Field

  • Building an in-ground pool would almost certainly need a permit, but it is critical that it be located away from your drainfield. The most obvious issue would be if you were to cut into your drainage system. However, even approaching too close might cause soil compaction in the surrounding area, reducing the life expectancy of the drain field. An above-ground pool adds a significant amount of weight to the earth. It is common to see sheds built on top of leach fields because the water that drains out will soak down into the drainfield and add a significant amount of water. While it is possible that the weight of the shed could cause some soils to contract, it is also likely that traffic from machines would increase. Larger sheds and pole barns should be maintained away from drainfields at all costs. They are unquestionably large and heavy enough to cause issues. They are also large enough to accommodate heavy vehicles, which will further exacerbate the situation. Some individuals choose to build gardens on top of the drain field to beautify the area. Make certain that you are not growing anything with roots that are large enough to penetrate the pipes. In most cases, there is a two-foot layer of dirt cover, but this might vary. When in doubt, it’s advisable to be careful and move the garden to a different location. Fence posts are commonly found in and around gardens. Make certain that the posts are not too large that they are digging into the drain field stone (aggregate). It is possible that huge posts or poles that are buried too deeply will pose an issue. Decks, flagpoles, and huge fences are examples of structures that might cause this. When a septic tank is replaced, it is possible that a leach field will be harmed. The big trucks required to transport the concrete septic tank will have a negative impact on the soils. A plastic septic tank is an excellent solution for completely avoiding the problem. Because they are small and lightweight, they can be carried by hand.

Having established the dangers associated with developing near your septic system, we can go on to discussing ways to avoid any difficulties from arising in the future. The most effective technique of preventive is to be aware of the locations of each component of your system.

How to Locate Your Septic System

Keeping track of where your system is at all times might be a challenge. A large number of consumers only get a glimpse of the entire system during the house purchasing inspection process. In the event that you still have access to your report, it may contain information on the system’s location, as well as a 2-D drawing of the system’s layout. We will provide photographs with our report in order to provide a more accurate reference for the location of the system components. The option to have someone come out and find your system is always available if you have misplaced your report.

Building near a septic tank and drain field can be hazardous, so exercise caution and use common sense while constructing any structure in the vicinity. To understand much more about having a septic system and how to properly maintain it, please see our booklet by clicking on the link below.

Distance from the home; basic safety concerns; suggestions for a successful installation; and more.

Tip

Depending on where you live, local ordinances and regulations that specify the distance between the septic tank and the home vary. However, the normal minimum distance is 10 feet between the two structures. Consult your local ordinances and regulations for a detailed answer as to how far your septic tank must be installed from your home. Requirements differ from one location to the next, although the standard minimum distance from the home is 10 feet in most cases. In the case of a private well for drinking water, however, keep in mind that many state departments of health demand a minimum distance of 50 feet between a new septic tank and a well.

It is possible that the septic tank will be placed considerably closer to the structure since it will be easier and require less plumbing in some cases.

Basic Safety Considerations

The distance between the septic tank and the home is dictated by local ordinances and regulations, which vary depending on where you live. However, the common minimum distance is ten feet. You should check with your local ordinances and regulations for a particular answer on how far your septic tank must be located from the house. The requirements vary from one location to another, but the standard minimum distance from the home is ten feet in most instances.

It is possible that the septic tank will be placed considerably closer to the structure since it will be easier and require less plumbing in some circumstances.

Tips for a Successful Installation

Plan ahead of time to get your water supply switched on prior to installing your septic tank. You must fill the tank with water as soon as it is placed in its final position for this to be possible. This has absolutely nothing to do with the septic system itself, but it is a prudent precaution. In the event of a heavy downpour, the groundwater may swell and a septic tank may float out of the ground, even if it has been buried. If this occurs, contact a qualified professional immediately. Repairing any damage done to the lines or to the tank itself, as well as putting the tank back in its original location, may be a costly and time-consuming endeavor.

Initially, you may be confident that you will remember the exact location of the marker when it is time to top up the tank — which is generally every three to five years — but your memory may fade over time.

In the absence of a marker, you may end up digging holes in the wrong place when it is time to service the tank.
