What Kind Of Septic Tank Do You Need In A Flood Zone? (TOP 5 Tips)

  • Above-ground septic treatment tank: If a site is at risk of flooding and becoming water logged the septic tank must be above ground. Below ground septic tanks: should not be used in areas that are likely to be flooded because the tank will be submerged in floodwaters both adding to area contamination and precluding acceptance of building sewage.

Can you have a septic tank without a leach field?

The waste from most septic tanks flows to a soakaway system or a drainage field. If your septic tank doesn’t have a drainage field or soakaway system, the waste water will instead flow through a sealed pipe and empty straight into a ditch or a local water course.

Can heavy rain affect septic tank?

It is common to have a septic back up after or even during a heavy rain. Significant rainfall can quickly flood the ground around the soil absorption area (drainfield) leaving it saturated, making it impossible for water to flow out of your septic system.

What happens to a septic tank in a flood?

Most septic tanks are not damaged by flooding since they are below ground and completely covered. However, septic tanks and pump chambers can fill with silt and debris, and must be professionally cleaned. If the soil absorption field is clogged with silt, a new system may have to be installed.

Can septic tank flood basement?

Septic tank flood damage can cause dangerous sewage water to back up into your home, posing a serious health threat. This is why it is so important to quickly and properly handle a septic tank flooded basement.

What is an alternative to a leach field?

Sand Filter This is one example of an alternative septic system without a leach field, which makes it compatible with environmentally sensitive areas. In some cases, the treated water can pass directly from the sand filtration system to the soil without needing to flow through more piping to a leach field.

What is an alternative septic tank?

An alternative septic system is a system that is different from the common traditional style septic system. An alternative system is required when the site and soil conditions on a property are limiting, or when the wastewater strength is too strong for the receiving environment (i.e. restaurants).

How do I stop my septic tank from flooding?

As a preventive management step, you should keep stormwater runoff away from your system as much as possible. Water from roofs and driveways should be diverted away from the septic tank and drainfield area. Make sure your downspouts aren’t pointed directly at your drainfield.

How long does it take for a flooded septic tank to drain?

In a conventional system, the septic tank holds wastewater for 2-3 days as the anaerobic bacteria treat it.

Why do I smell septic when it rains?

Raining often causes atmospheric pressure changes, which can lead to the air becoming heavy. As such, the methane gases typically found in the septic tank don’t flow through the vent as they normally would. Instead, they stay low to the ground, causing a foul smell similar to rotten eggs.

Does a septic tank stay full of water?

Depending on the size of tank and number of the home’s occupants, a septic tank will usually fill back up to its normal liquid level after it has been pumped out within a few days to a week.

How do you know if your septic tank is flooded?

If you see standing water above the drainfield or tank, your septic system is likely flooded. When you don’t see obvious standing water over the area, check the water level with a probe, or use an auger to dig down into the soil. Choose a spot that’s within 10 feet of the tank and 20 feet from the drainfield.

How far should a septic tank be from a house?

Most importantly, a septic tank must be at least seven metres from a house, defined as a ‘habitable property’. Septic tanks are built underground and release wastewater slowly into the surrounding environment. For this reason, they must be a set distance away from a home.

How much does it cost to pump a septic tank?

How much does it cost to pump out a septic tank? The average cost is $300, but can run up to $500, depending on your location. The tank should be pumped out every three to five years.

What will ruin a septic system?

Any paper products like tissues, paper towels, tampons, or sanitary products, even some heavier toilet paper, will clog your system if you flush enough of it. Wet wipes are another product that you should never flush into a septic system.

How long do septic tanks last?

A septic system’s lifespan should be anywhere from 15 to 40 years. How long the system lasts depends on a number of factors, including construction material, soil acidity, water table, maintenance practices, and several others.

Suggestions for Designing a Flood-zone Damage Resistant Septic System

The following recommendations have been modified and paraphrased from comparable recommendations made by Water Technology Engineering Ltd., a U.K.-based company that is listed below.

  1. In cases when the property is at risk of flooding and becoming water-logged, the septic tank must be elevated above the ground level of the surrounding soil. Below-ground septic tanks should not be used in flood-prone areas because the tank will be submerged in floodwaters, contaminating the surrounding area and preventing the tank from accepting sewage from the building
  2. Above-ground septic tanks should not be used in flood-prone areas because the tank will be submerged in floodwaters, contaminating the surrounding area and preventing the tank from accepting sewage from the building
  3. Considering that most existing buildings have a primary sewer line that exits below ground, the aboveground sewage treatment system must be built to take pumped wastewater from either a lift pump or a sewage ejector pump in order to function properly. Among the design characteristics are sufficient strength as well as a treatment design that is not adversely affected by the turbulence associated with pumped wastewater. Flood-proofing of electrical equipment: air blowers, aerators, and other equipment that is not built for submersion must be installed in a location that is above the floodwater level. Above-ground sewage effluent disposal: An above-ground mound system or raised-bed septic system should be used for areas that are likely to flood or where the groundwater level will reach too near to the bottom of a traditional effluent disposal system such as a soakbed or drainfield. In the case of systems that will release effluent into the environment during floods, further wastewater disinfection may be necessary. Systems such as ultraviolet disinfection or chlorine injection are examples. Code compliance: In most jurisdictions across the world, before commencing work on an update or replacement of a septic system, a construction permit and design approval are required.

If these different methods of decentralized wastewater treatment are carried out appropriately, they may safeguard public health, preserve important water resources, and help a community retain its economic vibrancy and viability. “Adequately managed decentralized wastewater systems are a cost-effective and long-term option for meeting public health and water quality goals, particularly in less densely populated areas,” according to the Environmental Protection Agency’s 1997 Response to Congress (PDF) (101 pages, 5.8MB, About PDF).

Septic Systems – What to Do after the Flood

What is the best place to go for information about my septic system? Please consult with your local health agency if you require further information or support. More information about onsite or decentralized wastewater systems may be found on the Environmental Protection Agency’s Septic Systems Web site. Do I need to pump my tank if the drainfield is flooded or saturated with water? No! Pumping the tank is simply a short-term remedy at the best of times. Pumping it out might cause the tank to attempt to float out of the ground, resulting in damage to the inlet and outlet pipes in the worst case scenario.

What should I do if my septic system has been utilized to dispose of wastewater from my business (whether it is a home-based or small-scale operation)?

Taking extra measures to prevent skin, eye, and inhalation contact with chemicals in your septic system that receives them is recommended if the system backs up into a basement or drain field.

For particular clean-up information, contact your state’s environmental protection agency or the Environmental Protection Agency.

What should I do with my septic system now that the floodwaters have receded? After the floodwaters have gone, there are numerous things that householders should keep in mind:

  • Drinking well water should be avoided until the water has been analyzed. Contact your local health department for further information. Do not use the sewage system until the water level in the soil absorption field is lower than the water level in the surrounding area of the home. If you feel that your septic tank has been damaged, you should get it professionally inspected and maintained. The presence of settling or an inability to take water are both signs of deterioration. Because most septic tanks are below ground and entirely covered, flooding does not usually do any harm to them. Septic tanks and pump chambers, on the other hand, can get clogged with silt and debris and must be properly cleaned. If the soil absorption field becomes blocked with silt, it may be necessary to build a completely new system. Septic tanks should only be cleaned or repaired by skilled professionals since they may contain potentially hazardous gases. Inquire with your local health agency for a list of septic system contractors who operate in your neighborhood. Cleaning and disinfecting the basement floor is necessary if sewage has backed up into the basement. To disinfect the area thoroughly, make a chlorine solution by mixing half a cup of chlorine bleach with each gallon of water. After a flood, pump out the septic system as quickly as possible to avoid contamination. Make careful you pump the tank as well as the lift station. This will clear any silt or debris that may have been washed into the system during the rainy season. It is not recommended to pump the tank while the drainfield is flooded or saturated. Pumping the tank is simply a short-term remedy at the best of times. Pumping it out might cause the tank to attempt to float out of the ground, resulting in damage to the inlet and outlet pipes. Do not compress the soil over the soil absorption field by driving or operating machinery in the vicinity of the soil absorption field. Soil that has been saturated is particularly prone to compaction, which can impair the ability of the soil absorption field to treat wastewater and ultimately result in system failure. Before reconnecting the electricity, check for any damage to all of the electrical connections. Examine to see that the manhole cover on the septic tank is securely fastened and that no inspection ports have been obstructed or damaged. Examine the plants surrounding your septic tank and soil absorption field for signs of disease. Damage caused by erosion should be repaired, and portions should be sodded or reseeded as needed to ensure turf grass cover.

Keep in mind that if the water table is high or your sewage system is threatened by floods, there is a possibility that sewage will back up into your residence. The only way to avoid this backup is to reduce the amount of strain placed on the system by utilizing it less frequently.

  1. What are some of the recommendations made by professionals for homes who have flooded septic systems
  2. And Make use of your common sense. If at all possible, avoid using the system if the earth has become saturated and inundated with water. It is unlikely that the wastewater will be cleansed, and it will instead become a source of pollution. Conserve as much water as possible when the system is re-establishing itself and the water table is depleted. Prevent silt from entering septic systems with pump chambers by installing a filter. The pump chambers have a propensity to fill with silt when they are inundated, and if the silt is not cleared, the chambers will clog and obstruct the drainfield. While the earth is still damp, it is not recommended to open the septic tank for pumping. Mud and silt may find their way into the tank and end up in the drain field. It’s also possible that emptying out a tank that’s been sitting in soggy soil can cause it to “pop out” of the earth. (Similarly, systems that have been recently installed may “pop out” of the ground more quickly than systems that have been in place for a longer period of time since the soil has not had enough time to settle and compress.)
  3. While the land is still wet or flooded, it is not recommended to dig into the tank or drainfield area. While the soil is still wet, it is best not to perform any heavy mechanical operations on or around the disposal area. These operations will have a negative impact on the soil conductivity. It is likely that flooding of the septic tank caused the floating crust of fats and grease in the tank to rise to the surface. Some of this scum may have floated to the surface and/or partially filled the outlet tee, but this is unlikely. If the septic system backs up into the home, first examine the tank for an obstruction in the outflow. Floodwaters from the home that are passed through or pumped through the septic tank will produce greater flows through the system. Clean up any floodwater in the house without dumping it into the sink or toilet, and give enough time for the water to recede. This may result in sediments being transferred from the septic tank to the drainfield, which will block the drainfield. Discover the location of any electrical or mechanical equipment in the system that may have been flooded and avoid coming into touch with them until they are dry and clean
  4. The presence of mud and silt has a propensity to block aerobic plants, upflow filters, trickling filters, and other media filters, among other things. Cleansing and raking of these systems will be required.

Septic Systems and Flooding

Image courtesy of the Environmental Protection Agency of the United States. Because they are located belowground, septic systems may not necessarily be the first thing on a homeowner’s mind when a flood strikes (out of sight, out of mind). Even yet, as South Dakotans continue to contend with an unusually rainy spring marked by record-breaking floods and snowmelt, some thought should be given to the condition of your septic system in order to prevent damage to your property and safeguard the health of you and your family.

Some of the warning indications of a failing septic system include a slow flushing or draining toilet, sluggish running drains throughout the house, foul aromas, and water beginning to back up into basement floor drains, among others.

What Should I Do if a Septic System Floods?

Receive articles, news, and videos about Systems/ATUs sent directly to your email! Now is the time to sign up. Systems/ATUs+ Receive Notifications “What can be done to safeguard a system against flooding?” is one of the questions I am asked the most often. As well as, “If the system has been flooded, what has to be done in order for it to be used once more?” In order to answer some of the specifics of these topics, let us first examine why we are concerned about systems flooding, as well as what kind of conditions and locales might result in flooding difficulties.

  • Under certain flood conditions, sewage from the system’s holding tanks can be sent back into the home through pipe that connects the house to it. This can result in considerable physical damage, as well as a health danger due to the presence of disease-causing germs and viruses in the wastewater. Long-term damage to the system, necessitating the need for repair or replacement, might result from floods. If untreated wastewater is discharged into the environment, it has the potential to cause environmental and water-quality harm.

There are several forms of floods that can occur. One example is when the region is located along a stream or river that floods on a regular basis and is associated with a designated floodplain area. Other situations include those in which the system is located in a landscape site that is susceptible to flooding or — as I prefer to think of it — ponding as a result of extreme precipitation events that occur at intervals of varying frequency depending on the particular position of the system. Clues based on topography In order to identify whether a system has been or will be built in a floodplain, it is necessary to consult maps accessible through municipal planning and zoning agencies.

  • The other types of floods that occur on a regular or irregular basis as a result of local precipitation events might be more difficult to forecast.
  • The soil maps produced by the United States Department of Agriculture indicate soil regions that have these properties.
  • It is possible to make a number of design and installation alterations if the system is situated in the flood edge region of the floodplain, which will help to protect both the system and the dwelling if a flood comes.
  • If possible, the drainfield section of the system should be installed at the greatest possible height on the property’s terrain.
  • A mound or at-grade system will be required if the system is located in a floodplain due to an issue with vertical separation distance, which is common in floodplains.
  • Unless the top of the mound is higher than the 100-year flood elevation, there shall be no direct-installed inspection or access pipelines.

Preliminary Design Considerations When dealing with floodplain and recognized ponding issues, the following design and installation concerns should be taken into consideration: A provision should be provided in the system, if a pump is used, to prohibit the pump from running when the pump tank is overflowed.

  • If the homeowner and service provider can identify whether extra water from groundwater intrusion into the tank is being pushed to the drainfield as floodwaters rise, it will be much easier for them to respond.
  • In a sewage treatment trench, there should be no inspection pipes or other installed apertures that go directly to the soil surface from the distribution media.
  • Put in place measures to prevent backflow from the septic tank into the house.
  • When the system becomes overburdened, provide a quick technique of diverting the flow of traffic.
  • Drain the septic tank and any additional tanks, such as pump tanks, and check them for structural damage before putting them back in use.
  • When pumping tanks, make sure that groundwater levels have decreased and that you are aware of tank buoyancy issues, which might cause the tank to float if the tank is emptied out.
  • Furthermore, if there are no holes, silt and other waste should not have made their way into the drainage system.
  • Saturated soil is particularly prone to compaction, which can result in system failure if not addressed.

Septic systems: What should you do when a flood occurs?

After a flood or severe rains, it is especially important to pay close attention to your septic system. Flooding at Deltona, Florida, during Hurricane Irma. Photo credit: Getty Images. P. Lynch, Federal Emergency Management Agency Septic systems, also known as onsite sewage treatment and disposal systems (OSTDS), are used by approximately 30% of Florida’s population to treat and dispose of home wastewater. The term “all water” refers to all water from restrooms, kitchens, and washing machines.

Overall, the most important things you can do to keep your system in good working order are to ensure that nothing other than bathroom tissue and kitchen fats go down the toilet, to reduce the amount of oils and fats that go down the kitchen sink, and to have the system professionally cleaned every 3 to 5 years, depending on the size of your tank and the number of people living in your home.

During and after a storm or strong rains, you should take extra precautions to protect your septic system from damage.

How does a traditional septic system work?

The most popular form of OSTDS is a traditional septic system, which consists of two parts: (1) a septic tank (above), which is a waterproof container buried in the ground; and (2) a drain field, also known as a leach field, which collects wastewater. Water from the tank is channeled into the drain field, which is often a network of subterranean perforated pipes that collect the wastewater. One of the functions of the septic tank is to separate solids (which settle to the bottom and produce assludge) from oils and grease, which float to the top and form ascum layers.

The effluent, which is located in the middle layer of the tank, drains out of the tank and onto the drain field, where it percolates down through the earth and into the water table.

During and after a storm or strong rains, you should take extra precautions to protect your septic system from damage.

What should you do after flooding occurs?

  • Reduce the strain on the septic system by using it less frequently or not at all until floodwaters recede and the soil has drained completely. Water must be able to easily flow from the drain field in order for your septic system to function effectively. When your system is flooded, water cannot drain correctly and might cause a backup in your plumbing system. Keep in mind that in most homes, all of the water that flows through the pipes ends up in the septic system. Floodwater should be cleaned up in the house rather than dumped into the sinks or toilets. You should avoid excavating near the septic tank and drain field when the earth is saturated with water. Drive large trucks or equipment over the drain field at your own risk. By utilizing heavy equipment or operating in waterlogged circumstances, you might compress the soil in your drain field, preventing water from adequately draining
  • However, this is not recommended. If the earth is still moist, you should avoid opening or pumping out the septic tank. If the tank is opened, silt and mud can enter the tank and end up in the drain field, decreasing the capacity of the drain field to drain water. It is also possible for a tank to come out of the ground when pumping under these conditions
  • If you feel that your system has been damaged, get the tank inspected and serviced by a professional. What is the best way to determine if your system is damaged? Settlement, wastewater backing up into residential drains, soil in the drain field remaining moist and never entirely draining, and/or a foul stench persisting surrounding the tank and drain field are all signs of a clogged drain field. Maintain a safe distance between rainfall drainage systems and the septic drain field. Take precautions to ensure that rainwater from your roof gutters does not drain into your septic drain field, as this adds an extra source of water that the drain field must manage.

More information about septic system upkeep following floods may be obtained on the Environmental Protection Agency’s website. By paying close attention to your septic system after flooding, you can make a positive contribution to the health of your family, your community, and the environment. Dr.

4 Things to Do When Your Septic Tank Is Flooded

If your neighborhood has recently been flooded or has been subjected to strong rains, you may discover that your toilet isn’t flushing properly and that your drains are draining more slowly than usual. It is possible that raw sewage will back up into your tub and sink drains. Drains that are slow or clogged may signal that the water table has risen over the level of your septic field and septic tank. If you believe that your septic system has been flooded, there are four things you should do immediately.

  • Check the level of groundwater in your area.
  • Septic tanks are typically located a few feet below the surface of the earth.
  • If you are aware of the location of your septic tank and drainfield, you should check the water level in the area to ensure that flooding is not a concern.
  • When there isn’t any evident standing water in the area, use a probe to check the water level or an auger to dig deep into the earth to find out how much water is there.
  • If your tests reveal that the water level is higher than the top of the septic tank, you should immediately cease utilizing the tank.
  • 2.
  • Until the Ground Becomes Dry When you believe that your septic system has been flooded, contact a septic pumping specialist immediately; however, you must wait until the earth has become less soggy before having your tank drained.
  • If a septic tank is pumped out when the earth is saturated, it may potentially float out of its location.
  • Following a decrease in the water table level, it is necessary to pump your system as quickly as feasible.
  • 3.
  • Approximately 70 gallons of water are flushed down the toilet per person every day in the average home.

The first step is to check for leaks in all of your fixtures. An inoperable toilet flapper or fill mechanism can leak up to 200 gallons per day, creating a backup of water that your flooded septic system doesn’t have room for. Other suggestions for keeping water out of the drains are as follows:

  • Prepare meals that don’t require cooking, such as sandwiches. Disposable flatware, such as paper plates and paper cups, should be used. Showers are preferable to baths because they are shorter. Save the rinse water and put it to good use on the plants. Only flush the toilet when absolutely essential

If your clothes washing machine drains into your main sewage line, it can cause a significant amount of water to be discharged into your septic system. Wash your garments at the laundry until the water table begins to fall below the surface. In the event that you must use the washing machine, wash only modest loads and wait a few hours between each load of laundry. 4. Make modifications to your septic system to make it more efficient. After your septic tank has been drained and your house drainage system has been restored to working order, you should make certain modifications to your system in order to minimize flooding problems in the future.

During a septic emergency, the backflow preventer prevents waste water from entering your home or building.

Also, check to be that your yard’s storm drainage does not overflow into your septic field and storage tank area.

Sewage Treatment Systems For Flood Risk Sites

Flooding and saturated soils pose a substantial threat to sewage treatment facilities, and as the United Kingdom has more regular extreme rainfall events, the issue of pollution from sewage treatment plants and septic tanks is becoming an increasingly serious concern for residents.

The Flood Risk Problem

Heavy rainfall can overwhelm the soil’s natural ability to absorb water, causing the ground to become saturated. The presence of more rain will result in surface flooding after saturation has been attained. Exacerbating the situation occurs when streams and rivers get overloaded, breach their banks, and overflow their banks. As a result of these conditions, human waste will contaminate soils and floodwaters, which can have significant repercussions. However, many “experts” have attempted to prevent sewage from polluting flood waters by designing sewage treatment plants/septic tanks with watertight lids, but such efforts have been proven to be a waste of time.

2.Through the opening in the tank’s cover.

The third way of tank flooding is the most commonly used.

Once surface flooding starts, a tank will typically only flood through channels 1 and 2. Wastewater from human beings is a highly toxic material. Pathogens found in sewage and wastewater can cause a variety of illnesses, including but not limited to:

  • Acute gastroenteritis, encephalitis, giardiasis, poliomyelitis, salmonellosis, Shigellosis, typhoid fever, yersiniosis, and yersiniasis are all conditions that can occur in the gastrointestinal tract.

Contamination of floodwaters with human waste can have devastating repercussions, including the following. It is capable of causing sickness in persons who will unavoidably come into touch with flood water both during and after the flood, such as during the clean-up process. Contamination of watercourses and the consequences for aquatic life It is most typical for municipal water supplies to be contaminated through the use of hosepipes and water supply pipe fittings. If this occurs, a significant risk is posed to the whole public, including those who are not immediately affected by the water.

  1. For obvious reasons, it is against the law for human waste to pollute agricultural land that is utilized for food production.
  2. Many diseases may survive in the environment for weeks (and in some instances months) at a time, posing a hazard to animals throughout this time.
  3. Almost all sewage treatment plants are equipped with some type of motor, which is responsible for propelling the treatment process along.
  4. For relatively modest systems, this will cost at the very least a few hundred pounds and at the very worst several thousand pounds.
  5. Others have encountered difficulties because developers failed to dig trial site evaluation holes when evaluating the appropriateness of drainage fields for their projects.

The Sewage Treatment Solution

Fortunately, there is a very efficient option for significantly lessening the impact of severe rains on sewage treatment plants while also ensuring that the sewage contained within them does not cause harm. The sewage infrastructure shown in the picture below should be erected if there is a possibility that a site may flood or that the land will get waterlogged: The foul drain from the building should be sent straight to a raw sewage pump station to prevent contamination of the environment. Manholes should not be present in this foul drain in order to reduce the risk of flooding.

  1. It is also desirable to have it elevated above ground level to improve visibility.
  2. Pump stations are not designed to handle large amounts of sewage.
  3. This moment, it is likely that the structure will have to be abandoned due to the significant flooding that is expected to occur.
  4. The Vortex sewage treatment facility, which is located above ground, is the second stage of the system’s design.

If a location is at risk of flooding or getting water logged, the tank must be elevated above the ground level. As a result of the following characteristics, Vortex is the only sewage treatment plant that may be utilized:

  • It can be erected free standing above ground
  • It can receive a pumped influent
  • It can receive a macerated influent
  • And it can receive a macerated influent.

In accordance with Rule Number 2, an aboveground sewage treatment facility must have the ability to accept pumping influent. For the following reasons, the majority of sewage treatment facilities fail to fulfill all three of the aforementioned criteria: They are not robust enough to be built without a surrounding structure. They have a primary storage tank on site. Primary tanks (such as septic tanks) are incapable of receiving pumped influent. This is due to the fact that the primary purpose of a Primary Tank is to separate particles from liquids in wastewater.

  1. It goes without saying that if the influent is macerated, it is difficult to separate.
  2. It can be mounded in a circle for aesthetic reasons, but this isn’t absolutely necessary.
  3. The air blower for the Vortex must be put on the tank lid in order to maintain it above the level of flooding water.
  4. A drainage mound is a drainage field that has been raised above the existing ground level for drainage purposes.
  5. This is unacceptable for two reasons: first, it violates the right to privacy.
  • Rule Number 2: An aboveground sewage treatment facility must be capable of receiving pumped influent. (See Figure 1). For the following reasons, the majority of sewage treatment facilities fail to fulfill all three of the aforementioned criteria: They are not powerful enough to be built without a surrounding enclosure. Their primary tank is located on the premises. It is not possible to pump influent into Primary Tanks (such as those used for septic tanks). Due to the fact that the primary purpose of a Primary Tank is to separate particles from liquids in wastewater, this is true. If the wastewater is pumped in, the power of the influent will stir up the Primary Tank, preventing it from settling down properly. If the influent has been macerated, it is obviously impossible to separate the two components. It is simple to set up the Vortex because all it requires is a concrete surface to be placed on which it may stand. A mounded spherical shape can be achieved aesthetically, although it is not required. 3. The air blower for the Vortex must be put on the tank lid in order to maintain it above the level of the flooding. An underground drainage mound completes the scheme. A drainage mound is a drainage field that has been raised above the existing ground level to facilitate drainage. Many locations with drainage fields suffer after lengthy periods of rain because the sewage system backs up as a result of the saturated ground’s inability to absorb any extra water. Due to a few of factors, this isn’t acceptable:

In accordance with Rule Number 5, septic tanks shall not be utilized on a site that has experienced or is projected to experience soil saturation or flooding. The exit of the Vortex may be equipped with a UV treatment system, which will eliminate 99 percent of any pathogens that remain in the effluent if this is desired. Drainage mounds are commonly misunderstood, and their design and construction need meticulous attention to detail. Because the suspended particles level of the liquor is too high, they are only suited for sewage treatment plant effluent and not septic tank effluent, according to the manufacturer.

If you require any assistance with drainage mounds, please contact our office at 01759 369915 for assistance.

If your location is at danger of flooding, you will not be eligible for an exemption and will be required to get authorisation for discharge from the Environment Agency, the Environment Agency Wales, the Northern Ireland Environment Agency, or the Scottish Environment Protection Agency.

Septic System Information and Care

When municipal sewer service is not available, a septic system that has been properly constructed and maintained is an excellent option for treating wastewater and protecting groundwater quality. A typical septic system is comprised of two key components: the septic tank and the drainfield (or leach field). Waste from toilets, sinks, washing machines, and showers is channeled into a septic tank, which is a holding tank that is typically constructed of pre-cast concrete or fiberglass and is proportioned according to the projected wastewater flow from a given-sized house or commercial establishment.

  • In the first stage of wastewater treatment, anaerobic bacteria (bacteria that can survive in an oxygen-free environment) break down solids into liquids and generate gas that is vented through the building’s plumbing vent stack.
  • The lack of oxygen inside the septic tank also has the added benefit of deactivating some of the disease bacteria that are prevalent in sewage.
  • Because it allows aerobic (oxygen-using) bacteria to continue deactivating the disease germs that remain in the wastewater, the drainfield serves as a secondary treatment facility for sewage.
  • Evaporation of water also occurs through the layer of soil that surrounds the drainfield.
  • That way, enough permeable or unsaturated soil is available to filter the wastewater before the remainder of it gets into the groundwater table and underlying aquifer.
  • In certain instances, modern wastewater treatment systems that “aerate,” or add oxygen to the wastewater, may be necessary to treat the effluent.

Septic System Care

Don’t flush cigarette butts, tampons, condoms, or any other indigestible things down the toilet or down the sink drain. Consequently, the exit filter or drainfield will become clogged. Never throw grease down the drain since grease cannot be digested by the septic system and will cause it to become clogged! rather than dumping it in the garbage, pour it into an empty container or bottle and throw it away. Make sure you don’t use excessive amounts of bleach or other cleaning agents in your septic tank since doing so will interfere with the bacterial operation inside the tank.

  1. Instead of doing numerous loads of laundry back-to-back, stretch your wash loads out over the course of the week to reduce the amount of water that the septic system has to treat (a normal wash load consumes between 60 and 90 gallons each load!).
  2. Roots from trees and plants will grow into the drainlines and cause them to get obstructed.
  3. Driving over your drainfield can cause the pipes to become crushed or the dirt surrounding them to become compacted, and driving over your septic tank can cause the lid to fracture or even fall apart!
  4. Consider the installation of water-saving showerheads, toilets, and other water-saving appliances in your home.
  5. Septic tanks should be pumped out every four to five years, according to the Florida Department of Health, in order to prevent the buildup of sludge in the tank over time.
  6. Stoppages and overcrowded drainfields are caused by leaking toilet flapper valves, which can allow hundreds of thousands of gallons of waste water to enter your septic system each day.

Flooding – What to Do

  • Use caution while using the sinks and toilets if the soil surrounding your home and septic system has been wet and flooded. Your septic system will not function properly
  • Plug all of the drains in the basement and dramatically restrict your water consumption until the system has had time to heal. If you are cleaning up floodwaters in your house or basement, do not put the water down the sink or toilet
  • Instead, use a bucket. While the earth is still soggy, it is not recommended to open the septic tank or have it pumped out. Water may enter the tank, and mud and silt may accumulate in the drain field. It is possible that pumping out a tank that is buried in saturated soil will cause it to “pop out” of the earth. You should avoid digging in the drain field area if the earth is still moist or if it has been flooded. Whenever possible, avoid working on or around the disposal field with heavy machinery while the soil is still moist. If you have any electrical or mechanical equipment in your septic system that have flooded, avoid touching them in the days after the accident. When electrical components are dry and clean, they should not be touched or handled. Before re-establishing electrical service, examine (or have them inspected) all electrical connections for damage. Examine to see that the manhole cover on the septic tank is securely fastened and that no inspection ports have been obstructed or damaged. If you (or your small business) has dumped caustic or toxic chemicals into your septic tank in the past and your system has backed up into your basement or drain field, you should take extra precautions to protect your eyes, skin, and lungs from the fumes. If you have any questions, please contact us. In order to discuss clean-up, you may need to contact your local DHEC Environmental Health office. Be mindful that flooding the septic tank causes the scum layer to rise to the surface, where it may have floated and/or partially stopped the outlet tee, resulting in sewage backing up into the home. Other issues that you may notice after flooding include the tank settling and the tank’s inability to receive water from the water source. Having your septic tank professionally examined and maintained as soon as possible is recommended. Because most septic tanks are below ground and entirely covered, flooding does not usually do any harm to them. Septic tanks and pump chambers, on the other hand, can get clogged with silt and debris and must be properly cleaned. If the drain field becomes clogged with silt, it may be necessary to install a whole new system. Cleaning and disinfecting the basement floor is necessary if sewage has backed up into the basement. To disinfect the area thoroughly, make a chlorine solution by mixing half a cup of chlorine bleach with each gallon of water. In the next weeks, take a look at the vegetation that has grown around your septic tank and soil absorption area. Remove and replace any erosion damage, then sod or reseed the area as needed to ensure turf grass coverage
