What should I do if my septic system floods?

  • If you suspect flooding of your septic system, here are four things you should do. 1. Check the Groundwater Level Drainfields for septic tanks are normally between 2 to 4 feet from the top of the soil. The top of the septic tank is usually a few feet below the soil.

How do you fix a flooded septic tank?

4 Things to Do When Your Septic Tank Is Flooded

  1. Check the Groundwater Level. Drainfields for septic tanks are normally between 2 to 4 feet from the top of the soil.
  2. Wait to Pump Until the Ground Dries.
  3. Reduce Water Sent Down the Drain.
  4. Make Changes to Help Your Newly Pumped Septic System.

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.

What happens if your septic tank overflows?

If the tank overflows, you’ll notice that the ground is very wet above this drainage area. If tree roots grow through pipes, the walls of the pipe could collapse and prevent proper drainage. Clogged or broken pipes can also cause overflow. Some septic system overflow happens because of improper design.

How do you dry out a septic system?

Reducing water usage in the home by 30 percent can dry out a soggy leach field. Conserve water by replacing standard faucet and toilet fixtures with low-flow versions and fixing any toilet or faucet leaks. Reduce water sent to the septic system by reusing water in the landscape where appropriate.

Will a flooded septic tank fix itself?

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.

How do you fix a septic tank that backs up when it rains?

After a major rain event, the only way to relieve pressure on the system is by using it less. If possible, reduce or eliminate water going down the drains until the drainfield dries out. An emergency septic service cleaning can provide temporary relief, but this is often a futile exercise in battling mother nature.

Why is my septic tank flooding?

Flooding in a drain field means that the ground has been completely saturated with water. In such cases, there is a high probability that water will be able to flow back into the septic tank through compromised underground access ports. To conserve water, wash dishes in a small tub and dump the water outside your home.

Can I take a shower if my septic tank is full?

Only the water would get out into the leach field in a proper system unless you run too much water too fast. The thing to do is to run your shower water outside into it’s own drain area, but it may not be allowed where you are. Used to be called gray water system.

Will a drain field dry out?

The remaining liquid evaporates or penetrates far beneath the surface. That is, unless the surface is saturated. If your drainfield is taking on more water than it can absorb, it never has a chance to dry out and make room for more water. As long as your family is awake, you’re sending water to that drainfield.

What are the symptoms of a full septic tank?

Here are some of the most common warning signs that you have a full septic tank:

  • Your Drains Are Taking Forever.
  • Standing Water Over Your Septic Tank.
  • Bad Smells Coming From Your Yard.
  • You Hear Gurgling Water.
  • You Have A Sewage Backup.
  • How often should you empty your septic tank?

Is it normal for a septic tank to be full of water?

A septic tank should always be “filled” to its normal liquid level, or the bottom of the outlet pipe which carries effluent to the absorption area. If the tank is overfull, this is usually a sign of problems with the absorption area.

How long does it take for a septic drain field to dry out?

Except for mound systems, most drainfields are 2 to 4 feet below the ground surface. The groundwater will take time to recede to the level of the bottom of the drainfield. This could happen within a week or two or require a couple of months.

Can a running toilet flood a septic tank?

The steady flow of water from a leaky toilet or faucet day and night can quickly flood your septic tank as well as the ground around the drain field, making it impossible for water to flow out of your septic system, eventually leading to septic system failure. This is referred to as hydraulic overloading.

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.

  1. 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.
  2. If your tests reveal that the water level is higher than the top of the septic tank, you should immediately cease utilizing the tank.
  3. 2.
  4. 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.
  5. If a septic tank is pumped out when the earth is saturated, it may potentially float out of its location.
  6. Following a decrease in the water table level, it is necessary to pump your system as quickly as feasible.
  7. 3.
  8. 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.

When your septic system is inundated, call Eckmayer Inc right away.

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.

Protecting Your Septic System From Flooding

Septic waste can back up into your home during floods, and there are precautions you can do to minimize the risk of this happening. Photograph courtesy of George Hurd of Penn State Extension A buildup of water in your septic system’s drainfield might lead it to overload, which can cause the treatment of your wastewater to slow down or stop completely. If this occurs, you face the risk of septic waste backing up into your home, which is particularly dangerous if your drainfield becomes plugged.

  1. There are measures that you may take now to assist secure your system before this occurs, if you choose.
  2. Rainwater collected on rooftops and driveways should be channeled away from the septic tank and drainfield for disposal.
  3. To encourage rainwater to flow off of your system rather than onto it, the soil above your system should be somewhat mounding up.
  4. Have your septic system examined at least once a year.
  5. The sludge and scum levels in the tank should be examined on a regular basis, and the drainfield should be monitored for smells, damp areas, and surface sewage on a regular basis.
  6. This is an extremely crucial stage in the ongoing maintenance process.

It is recommended that you have a licensed plumber install a backflow preventer on the building sewer if you live in an area that is susceptible to flooding, according to the Minnesota Pollution Control Agency factsheet, “What To Do With Your Septic System During A Flood.” If you live in a flood-prone area, you should have a backflow preventer installed on the building sewer so that sewage does not backup into your home during a flood.

Because there is some worry that a basic check valve may fail to close correctly, sewage may back up into the residence, it is advised that a backflow preventer be installed.

Additional information on managing your septic system during a flood can be found in the U.S.

What to do for Your Septic Tank After a Flood – Septic Maxx

The hurricane season has begun in earnest. Storms and floods are more prevalent this time of year than at any other time of year, which is why it is critical to understand how storms influence your septic system and how to prepare for them. Flooding properly saturates the soil and puts all components of the septic system in danger of being dismembered or destroyed. Septic tanks, especially those that are lightweight and have just been cleaned, are particularly vulnerable to flooding when they are not properly maintained.

Post-Flood Septic Care Tips

When a flood is occurring, there isn’t much you can do to preserve your system; but, once the floodwaters have receded, there are certain precautions you should take. First and foremost, refrain from consuming any water until it has been examined by the local health authority. During a flood, contaminated groundwater may readily overflow a well, putting everyone who consumes it at risk. When it comes to septic system maintenance, there are a few things that homeowners should keep in mind:

  • Use of the sewage system should be avoided until the water level in the drain field is lower than the water level in the surrounding area. Make an appointment with an expert to examine your septic system for damage or disturbances. Despite the fact that the septic tank itself is not susceptible to damage, dirt and silt can readily clog the pipes. Do not attempt to repair septic tank problems on your own. It is possible to breathe hazardous gases and vapors from septic tanks, which have life-threatening repercussions if they are breathed. As soon as possible, get your septic tank pumped by a competent service. Pumping the tank and the lift station to remove silt and debris are both recommended. Heavy machinery or equipment should not be driven over septic system fixtures in order to prevent soil compaction over the drain field
  • Check to check that the manhole cover is securely fastened and that the inspection ports are free of obstructions, and Examine the vegetation growing above and in the drain field of your septic tank.

It’s crucial to understand that when the water table is high or when there is a flood, the likelihood of sewage backing up into your property increases significantly. The only way to avoid this from happening is to minimize water consumption during and after a flooding event. It is possible for germs to be lost from your septic system during flooding and every time you pump your septic tank. Septic Maxx will replenish the bacteria in your system. Septic Maxx Trillion Tabs replenishes billions of bacteria that have been lost during a pump out, and they also help to prevent delayed flushing and blocked septic tanks from occurring.

What happens to your septic system during heavy rain?

In the case of a typical septic system, excessive rainfall that occurs in conjunction with flooding might cause the system to malfunction. As precipitation washes over your drain field, the effluent from your septic tank will have nowhere to drain since the earth underneath the drain field has already become saturated with water from the downpour. Septic waste will begin to back up inside the home and overflow onto the yard as a result of this situation. According to traditional systems, waste is held for two to three days in the septic tank while the anaerobic bacteria treat it.

The pathogens in the water are eliminated by aerobic bacteria as it travels through the gravel in the leach field before the water is recycled back into the groundwater system.

Unless the leach field is completely flooded, the partially treated water from the septic tank does not proceed through the ultimate treatment process in the drain field, which is necessary. This will cause the wastewater to build up in the tank and overflow into the leachfield as a consequence.

Signs of a flooded drain field

The greatest thing you can do if you are having severe rains in your region is to keep an eye out for any telltale indications of a flooded drain field. Here are a few examples of warning signs:

  • Drains that are sluggish in the house
  • When flushing the toilet, the water drains slowly
  • Gurgling noises coming from the toilet and drains
  • Backing up of water into the floor drains and the basement is an issue.

Septic systems are intended to manage solely the wastewater generated by the home. In reality, the size of the septic tank that is put on a property is determined by the number of people that live there (number of bedrooms). If storm runoff water gets into the septic tank, it will overflow, and because the soil in the leachfield will already be excessively saturated, the water will begin to back up into the home or from the manhole, causing it to fail.

Maintaining the septic system BEFORE the heavy rains

If your septic system is properly maintained, it should be able to tolerate strong rains without failing. In order to prevent this from happening, you should always pump your septic tank on time and check to see that it is operating smoothly throughout the year. Due to the fact that anaerobic bacteria are required to liquefy the waste in your septic tank, it is in your best interest to guarantee that the bacteria in the tank are in the best possible condition. First and foremost, you must refrain from using any poisonous agents that might kill the beneficial bacteria, such as scented soaps, antibacterial soaps, paint, and so on.

It is the enzymes and bacteria that are introduced into the septic tank by the additives that aid in the restoration of its efficiency.

What to do if the weather forecast warns of a looming storm

If the weather prediction has indicated that a flood is imminent, take the following preventative procedures to assist protect your system in advance of the flood:

  • Remove anything that might be an entrance point into the septic system
  • To guarantee that additional rainwater does not find its way into the tank, all inspection points should be sealed. Turn off the pump at the circuit box before the area becomes completely submerged in water. If your mound system has a pump at the lift station, turn off the electricity to it if it is connected to the grid. If you want to safeguard the pump from harm, you may even take it out of the system completely. To prevent electrical wire from becoming damaged or from being shocked, it is necessary to waterproof any electrical connection in the system.

Maintaining the septic system DURING the heavy rains

Once the heavy rains begin, it is recommended that you refrain from using water for anything that is not absolutely necessary. The goal is to keep the system from becoming even more overburdened than it already is. For example, flush the toilet only when it is absolutely required and decrease the number of showers or the length of each shower. Using the toilet and faucets should be avoided entirely if your drain field becomes clogged with water. A flooded drain field indicates that the system is already clogged, and you don’t want to make an already poor problem even worse by adding to it.

Maintaining the septic system AFTER the heavy rains

Do not attempt to get the septic tank drained until the floodwaters have subsided completely. While flood waters are rising, pumping the tank in the middle of a flood might force it to float out of the ground, causing significant damage to the entire system. One thing to keep in mind is that the problem is not with the septic tank itself, but rather with moist soil in the drain field.

The most effective course of action is to discontinue usage of the system until the floodwaters recede and the earth around the drain field region has dried up. Here are some suggestions to assist you in reducing the amount of water that enters your septic tank.

  • Do not discharge the water from the basement sump pump into the septic tank. Rainwater from your roof gutters should be diverted away from the drain field to avoid flooding. Discontinue the use of the garbage disposal and dishwasher. Showers should be taken less often and for shorter periods of time
  • Sponge baths should be used whenever feasible. While brushing your teeth, do not turn on the water. Alternatively, you might use a laundry service.

Sometimes the backlog is a more serious problem than the stormwater itself; it might be caused by a clogged drainfield, for example. In the event that organic waste is allowed to exit the septic tank prematurely, it may clog the drainfield, resulting in sewage backups. A pumping operation will not solve the problem in this situation since the tank will quickly fill up again after the pumping operation is completed. To eliminate the blockage, the most effective technique would be to use a shock therapy.

Each of these biological additions introduces millions of bacteria into the septic system, liquefying the organic waste and unclogging the system as a result of their presence.

Safety precautions after a heavy downpour

If the floodwaters were very severe, you could be forced to temporarily vacate your residence. Unless it is absolutely essential to evacuate, do not return to your home until you have checked with the appropriate authorities to confirm that all advisories have been rescinded. Other vital safety precautions to be aware of are as follows:

  • When the dirt around the drain field is still moist, it is not recommended to dig around it. Heavy machinery should not be used over the drainfield as well since it might produce soil compaction, which will make it difficult for aerobic bacteria in the drainfield to obtain adequate oxygen. It is possible that the scum layer in the septic tank rose to the surface and blocked the exit. As a result, you should inspect the outlet tee once the flooding has stopped to ensure that it is not obstructed. Before handling any of the electrical equipment that are part of the system, make sure they are fully dry. Upflow filters, media filters, aerobic plants, and other components of sophisticated systems that are susceptible to clogging by mud and debris from floods might get clogged. As a result, you should properly clean these systems before bringing them back into service.


Providing you take excellent care of the system before the water hits, it should be able to withstand the storm without difficulty. That being said, there are some storms that are simply too severe for any system to manage, especially if you continue to use water in the manner in which you are used. If this is the case, you may want to consult with an expert who can evaluate the system and assist you in correcting any damage that may have occurred. Otherwise, simply adhere to the recommendations provided above and you will be OK.

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


If the soil around your house and septic system has been saturated and inundated, avoid using your sinks and toilets. Your septic system is not going to function properly. Shut off any basement drains, and dramatically restrict water consumption until the system has had time to recuperate. It is not a good idea to throw floodwater into your sink or toilet if you are cleaning up floodwater inside your house or basement. While the earth is still damp, avoid opening the septic tank or having it pumped out.

  • It is possible that pumping out a tank that is submerged in saturated soil will cause it to “pop out” of the earth.
  • Whenever possible, avoid working on or around the disposal field with heavy machinery while the earth is still moist.
  • When electrical components are dry and clean, they should not be touched or worked on.
  • To check for blockages or damage to inspection ports, check that the manhole cover on the septic tank is secure.
  • In order to discuss clean-up, you may want to contact your local DHEC Environmental Health office.
  • Following a flood, you may notice other difficulties such as the tank settling and the tank’s inability to receive any more water.
  • Fortunately, because most septic tanks are underground and totally enclosed, they are not affected by flooding.
  • An entirely new system may be required if the drain field has become choked with silt; Cleaning the area and disinfecting the floor are necessary if sewage has backed up into the basement.
  • Keep an eye on the vegetation that has grown around your septic tank and soil absorption area in the upcoming weeks.

In order to provide turf grass coverage, repair erosion damage and sod or reseed the area as needed.

Septic Systems and Flooding

Image courtesy of the United States The Environmental Protection AgencyBecause they are underground, septic systems are not often the first thing on a homeowner’s mind during a flood (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.

How to Deal With Your Septic Tank After a Flood

Septic tanks may be at risk if you have recently suffered flooding in your property. It may become clogged with rising ground water or leak through the lid, rendering it unfit for human consumption. Following these guidelines after a flood will help to ensure that your septic tank is properly cared for.

  • For the first two weeks following the flood, try to keep home water usage to a bare minimum. When the water table in your sewage system is high, it is possible that sewage will begin to back up into your home. The only way to prevent this from happening is to utilize the system less frequently. Drinking well water should be avoided until the water has been analyzed by your local health agency. When the field around the septic system becomes flooded, it frequently becomes unable of holding the effluent from the septic tank. If possible, try to limit how much water you spend on your system until it subsides
  • When there is a flood, or even after a flood, don’t have the tank pumped since the ground is still too wet. Using a pump is only safe when the amount of water in the tank is fully below the tank’s capacity. Foot and vehicle traffic should be restricted across the drain field because damp earth compacts readily and has the potential to destroy the septic tank beneath it. It is critical to deal with sewage backup in your house as soon as possible and with extreme caution. Contact your local government or health department for further information. Check to see that no children or pets come into contact with sewage that has backed up outside your home. A chlorine bleach solution should be applied to the afflicted area once the solids have been removed. If your home has been polluted by sewage, you should evacuate immediately. Before reconnecting the electricity, check for any damage to all of the electrical connections.

After a flood, the best course of action is to have an expert check your system. For those of you who have lately experienced flooding, contact Boston Drain Company to get your septic system inspected right now! 617-265-8888

What To Do With Your Septic System Before & After a Flood –

  • Installing a backwater valve in your house, covering low-level drains during a flood event, and limiting water consumption in the aftermath are the best ways to keep your home clean and dry. As soon as you become aware that flood conditions are imminent, turn off all pumps and electrical components that are running in the system. Additionally, if you use a water softener, you should turn it off as well. Inspect rain gutters to ensure that water is not being diverted into the septic system’s drain field (also known as the “leach field”). Be aware of the distance between your tank and the ground below it
  • If this information is not included in any installation documentation, probe the ground above to find out

The aftermath.

  • If you notice a problem with your septic system, contact the local authority in charge of septic systems as soon as possible. They can provide information and advise. They may also recommend you to the Health Department if the case is very serious
  • However, this is not guaranteed. Reduce home water consumption as much as possible during a flood and in the days and weeks after – it may take several weeks for the earth to dry out completely. For situations when your system is restricted or useless, try using portable toilets in addition to paper plates and disposable/recyclable utensils in place of your regular dishes. Pay a couple visits to the local laundry instead of operating your own washing machine, and ask friends if they have shower facilities if possible
  • Floodwaters can enter a septic tank through leaks in the lid or the inlet/outlet pipes, and the tank will overflow. The coating of scum and other grossness that floats on top of the effluent might clog the intake and/or outflow, resulting in backups of the effluent. If your drains are not draining properly or sewage is entering your property, inspect these pipes and, if they are safe, clean them. Backups can also occur as a result of a flooded drain field that is unable to handle the volume of waste being discharged from the tank. It is recommended that you use the system as little as possible until the water has receded. If sewage has backed up into the house, it must be dealt with as soon as possible and with care. To learn more about cleaning up after a sewage backlog, consult our page. Ascertain that dogs and children are not able to access the polluted area if sewage has backed up outside the house before proceeding. Solids should be eliminated, as well as as much wastewater as is practicable. It is possible to apply hydrated lime (also known as “slaked”) or a chlorine bleach solution straight to the ground and allow it to sit for up to 24 hours. It is necessary to use enough lime to elevate the pH of the soil to 12, which will kill the majority of bacteria. It is not recommended to have the tank pumped during a flood or while the ground is still flooded. When the water level in the tank is fully below its maximum capacity, pumping is considered safe. It is best to remove only half of the tank contents if it is safe to do so. If you remove any more, the tank will float out of the ground due to its newly discovered buoyancy in the moist soil. Pay particular attention to tanks made of plastic or fiberglass that have just been installed since they are more prone to popping out. Pumping can begin when water is around one foot below the surface of the earth in a mound system. After that, the system should be safe for only restricted use. Once the water level has been restored to a safe level, inspect the tank for floodwater. If silt and other debris are present, the tank should be pumped to ensure that they do not clog the drain field. Before regular system performance may continue, the water level under the drain field must be lower than the water level around the home. When the water level surrounding a septic tank is low enough to allow for safe pumping, but the drain field is still wet, the tank might be utilized as a “holding tank.” An initial pumping will maintain the water level within the tank low enough to prevent discharge to the drain field if there are appropriate conservation measures in place to prevent it. Pumpings will be required on a regular basis until the field dries out, and the frequency will be determined by your household’s water use and the capacity of your tank. Foot and vehicle traffic across the drain field should be kept to a minimum. Wet, compaction-prone soil reduces the efficacy of the drain field’s ability to appropriately handle wastewater. If your system has been flooded, it is usually recommended that a professional check the system. There are just too many things that may go wrong and go unnoticed by the inexperienced eye. In the same way, there are a lot of risks and consequences associated with septic systems that are not functioning properly. Professionals should be consulted for any diagnostic or repair work.
