It comes down to daily water usage. Most residential tanks have a capacity ranging from 750 gallons to 1,250 gallons and the average person uses 60 gallons to 70 gallons of water a day.
- The volume of water that a septic system can handle depends on the size of your tank. For most homes, the septic tank can hold around 1,000 gallons of water every day. While this should be sufficient for any home, leaking faucets can dramatically add to your water usage, making it insufficient.
Can you put too much water in a septic tank?
Excessive water is a major cause of system failure. Too much water from laundry, dishwasher, toilets, baths, and showers may not allow enough time for sludge and scum to separate. The less water used, the less water entering the septic system, resulting in less risk of system failure.
How much water can I use on septic?
The septic tank and drain field should have adequate capacity to hold two day’s worth of waste water even during peak use. The two day recommendation is usually long enough to allow solids to settle to the bottom of the tank.
How much water should a septic system handle per day?
If it is properly designed per the number of people that can potentially live in the house (suggested 150 gals per day per bedroom ) it can easily handle every day flows with room for extra. So if you have a 3 bedroom house your system should be designed to handle 450 gallons per day.
Should you fill a new septic tank with water?
2 Answers. Yes the system should be filled with water and the installer should have done that. There is a good chance the tanks can float out of the hole if it rains heavy when they are first put in if you do not put water in them.
How do u know when your septic tank is full?
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?
Does shower water go to a septic tank?
From your house to the tank: Most, but not all, septic systems operate via gravity to the septic tank. Each time a toilet is flushed, water is turned on or you take a shower, the water and waste flows via gravity through the plumbing system in your house and ends up in the septic tank.
Can you use too much septic treatment?
Answer: One dose of Rid-X® per month treats septic tanks up to 1500 gallons. Recommended amounts are based on laboratory tests and results. Over-use of the product will not create any problems for the septic system or plumbing, however it is not necessary.
How do I lower the water level in my septic tank?
You can reduce the amount of water pumped into your septic tank by reducing the amount you and your family use. Water conservation practices include repairing leaky faucets, toilets and pipes, installing low cost, low-flow showerheads and faucet aerators, and only running the washing machine and dishwasher when full.
Do septic tanks hold water?
The septic tank is a buried, water-tight container usually made of concrete, fiberglass, or polyethylene. Its job is to hold the wastewater long enough to allow solids to settle down to the bottom forming sludge, while the oil and grease floats to the top as scum.
How many gallons should a septic tank be?
The correct size of the septic tank depends mostly on the square footage of the house and the number of people living there. Most residential septic tanks range in size from 750 gallons to 1,250 gallons. An average 3-bedroom home, less than 2500 square feet will probably require a 1000 gallon tank.
How do I calculate the size of my septic tank?
The formula is length (feet) x width (feet) x 1 foot x 7.5 gallons, which is the volume for 1-foot depth. To find the volume for 1 inch I divide the volume by 12 to give me gallons per inch. For our example this is 5.16 feet x 7.5 feet x 1.0 foot x 7.5 gallons per cubic foot = 290.2 gallons.
How fast does a septic drain?
A septic tank between 1,000 – 1,250 gallons in size generally takes around 20-30 minutes to empty. A larger tank (1,500 – 2,000 gallons) will take about twice as long, between 45-60 minutes.
How long does it take to fill a 1000 gallon septic tank?
Therefore, it will take about 5 years for one adult to fill 300 gallons of a 1,000-gallon septic tank with sludge and scum. A family of four will fill the 300-gallon storage volume of a 1,000-gallon septic tank in about 1.5 years.
Can heavy rain cause septic problems?
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.
Managing waste: Household septic systems – Part 1
It is important to understand how a residential wastewater treatment system works in order to safeguard one’s own health and that of the environment. After it has been flushed down the toilet or sink drain, what happens to the waste water generated in your home? There are two alternatives: This waste water is either transported to a municipal waste water treatment facility where it is cleaned and returned to the environment, or it is collected and treated on the premises through a septic system before being returned to the environment.
This accounts for more than a third of all households in the state of Michigan.
There are two main components of a septic system: an absorption or drain field and a septic tank.
The majority of tanks are double-chambered, which means that the tank is separated into two compartments.
- A pipe connects the drain field to the tank, which allows for easy drainage.
- Wastewater is discharged from the residence through the sewer line and into the septic tank.
- This is referred to as the scum layer.
- It is around two-thirds of the way up the tank from the bottom that a baffle or T-pipe is positioned.
- The liquid waste, referred to as effluent, is introduced into the absorption field by gravity, which distributes the effluent uniformly across the rows of pipes.
- It is recommended that the septic tank and drain field have sufficient capacity to retain two days’ worth of waste water, even during peak usage.
- Calculate the size of your septic tank by entering the information in the box below.
For most septic tank sizes, 150 gallons per bedroom is used to calculate the appropriate size for the system.
The capacity of your septic tank should be sufficient to contain two days’ worth of effluent.
Which is more important: Amount for two days OR Septic tank capacity If the quantity of waste water generated in two days exceeds the capacity of your septic tank, you must either lower the amount of waste water generated or improve your system.
Home*A*Systbulletin WQ51 is a home automation system.
The amount of waste water that enters the system and the amount of water that may be absorbed by the soil define the size of the system.
Gravely or sandy-type soils cause waste water to pass through the soil too quickly for treatment to be effective.
Clay or compacted soils may retain water for an excessive amount of time before it is absorbed, causing the system to become anaerobic (without oxygen), resulting in bad smells and the possibility of system failure. Articles on MSUExtension that are related:

Septic System Basics
When a household isn’t connected to a public sewage system, it normally relies on septic systems to treat and dispose of wastewater. Sewage treatment systems require a substantial financial commitment. The correct maintenance and upkeep of a well-designed, installed, and maintained system will provide years of dependable and low-cost service. The failure of a system can become a source of pollution and public health concern, resulting in property damage, ground and surfacewater pollution (such as contamination of well water used by you and your neighbors), and the spread of disease.
Aside from that, if you are planning to sell your property, your septic system has to be in good functioning order.
Septic systems are available in a variety of configurations to accommodate a wide range of soil and site conditions.
A conventional septic tank system is composed of three major components:
- This is known as the Septic Tank. In order to remove particles from wastewater, store and partially decompose as much solid material as possible, while allowing the liquid (or effluent) to flow to the drainfield, a septic tank must be installed. more
- The Drainage System After the particles have settled in the septic tank, the liquid wastewater (also known as effluent) is released to the drainfield, which is also known as an absorption or leach field, or both. more
- The Soil is a very important factor. The soil under the drainfield is responsible for the ultimate treatment and disposal of the septic tank effluent once it has been treated. Following the passage of wastewater into the soil, organisms in the soil remediate the effluent before it percolates downward and outward, eventually entering ground or surface water sources. A drainfield’s efficacy is also affected by the kind of soil
- For example, clay soils may be too tight to allow much wastewater to run through, while gravelly soil may be too coarse to give much treatment.
- Septic System Inspection Done at Home In order to aid you in examining your system, a VideoField Guide and Checklist may be available at the bottom of the homepage.
Homeowners and residents have a significant impact on the functioning of their septic systems. Overloading the system with more water than it is capable of handling might result in system failure. A septic system can also be damaged by the improper disposal of chemicals or excess organic waste, such as that produced by a trash disposal. The following maintenance suggestions might assist you in ensuring that your system provides long-term, effective treatment of domestic waste.
Inspect and Pump Frequently
The most critical step in keeping your septic tank in good working order is to eliminate sludge and scum build-up before it may flow into the drainfield. The frequency with which your tank has to be pumped is determined by the size of the tank, the number of people in your family, the quantity of water utilized, and the amount of solids (from humans, garbage disposal, and any other waste) that enter the tank’s drainage system. Tanks should be pumped out on average every 3 to 5 years, depending on usage.

- Septic Inspection and Pumping Guide
Use Water Efficiently
System failure is frequently caused by an excessive amount of water. The soil beneath the septic system must be able to absorb all of the water that is used in the residence. Too much water from the washing machine, dishwasher, toilets, bathtubs, and showers may not provide enough time for sludge and scum to separate properly in the drain.
The less water that is consumed, the less water that enters the septic system, reducing the likelihood of system failure. For further information on water conservation, visit:
- Indoor Water Conservation
- Every gallon of water conserved equates to a savings of $1.00.
Minimize Solid Waste Disposal
What you flush down the toilet can have a significant influence on the performance of your septic system. Many things do not breakdown properly, and as a result, they accumulate in your septic tank. If you have the option of disposing of it in another manner, do so rather than introducing it into your system.
Keep Chemicals Out of Your System
Protect your septic system against home chemicals such as caustic drain openers, paint and pesticides. Also avoid flushing down the toilet with chemicals such as brake fluid, gasoline, and motor oil. The improper dumping of dangerous substances down the drain is damaging to the environment, as well as the bacteria that are necessary for the breakdown of wastes in a septic system, and should be avoided.
Septic System Additives
It is not essential to add a stimulant or an enhancer to a septic tank in order to assist it in functioning or “to restore bacterial equilibrium.” The naturally occurring bacteria required for the proper operation of the septic system are already present in human excrement. Septic systems, like automobiles, are designed to offer long-term, effective treatment of residential waste if they are properly run and maintained on a regular basis. The majority of systems that fail prematurely, on the other hand, are the result of poor maintenance.
In the event that your septic system fails, call Thurston County Environmental Health at 360-867-2673 for assistance.
- Odors, surface sewage, moist areas, or a dense growth of plants in the drainfield region are all possible problems. Backups from the plumbing or septic tank (which are often a dark liquid with a foul odor)
- Fixtures that take a long time to drain
- The plumbing system is making gurgling sounds. Your drainfield may be failing if you have a well and tests reveal the presence of coliform (bacteria) or nitrates in the water from it. Even in the midst of a drought, the drainfield is covered with lush green grass.
How much water does a septic tank hold?
Asked in the following category: General The most recent update was made on June 30, 2020. A person uses around 60 to 70 gallons of water each day on average. Designed with the idea that there are two people in each bedroom, Tanks are quite spacious. As a result, a conventional aseptic tank can handle around 120 gallons per bedroom every day on average. Septic tanks for residential use are typically between 750 and 1,250 gallons in capacity. An aseptic tank is a self-contained device that is meant to retain effluent from a residence.
In the same vein, what are the indicators that your septic tank is overflowing?
- Water that has accumulated. If you notice pools of water on your grass surrounding your septic system’s drain field, it’s possible that your septic tank is overflowing. Drains that are slow to drain
- Odors
- A lawn that is extremely healthy
- Sewer backup
In a similar vein, one would wonder if one can put too much water in a septic tank. System failure is frequently caused by an excessive amount of water. Every drop of water entering the residence must be absorbed by the earth beneath theseptic system. It is possible that too much water from the laundry, dishwasher, toilets, baths, and showers will not provide enough time for sludge and scum to separate properly. Is it true that shower water goes into the septic tank? The distance between your home and the tank is: The majority of septic systems, but not all, function using gravity to transport waste to the septic tank.
When you flush a toilet, turn on the water, or take a shower, the water and waste run through the plumbing system in your home and into the septic tank, which is a gravity-fed system.
HOW EXCESSIVE WATER AFFECTS YOUR SEPTIC TANK AND WHAT TO DO
Septic systems are built with a certain capacity in mind, which is determined by the quantity of water used in a household. By exceeding this capacity, the system’s ability to handle wastewater can be severely compromised, perhaps resulting in the pollution of drinking water sources. Indoor and outdoor water consumption should be regulated to avoid overloading your septic tank, which will also help to extend the life of your tank. Find out more about septic tank overload and simple ways to conserve water while yet safeguarding your septic system by continuing reading.
- When functioning correctly, a septic tank should allow solid waste to settle to the bottom of the tank and microbes to break down organic waste in order to provide nutrients for the garden.
- A septic system that is overloaded does not enable sediments to settle properly and does not allow for the essential bacterial activity.
- An excessively high flow rate of wastewater might also reduce the amount of bacteria present in the tank, resulting in insufficient wastewater treatment.
- Here are a couple of suggestions to get you started.
- If you’re in the market for a new washer, consider a front-loading model, which is more energy and water efficient than a top-loading model, according to Energy Star.
- However, make an effort to launder your clothes more frequently, preferably several times a week.
- Reduce the amount of shower water wasted.
Consider taking fewer and shorter showers, as well as shutting off the water while you are lathering, in order to conserve more water.
Reduce the amount of water you flush down the toilet.
To reduce waste, consider flushing the toilet numerous times before using it for the first time.
If you have older toilets that tend to use a lot of water, consider replacing them with modern, water-efficient toilets to see a considerable reduction in your water usage over time.
Toilet leaks account for a significant portion of water waste in the average household.
Lawn Maintenance Should Be Conscientious For your landscape requirements, drip irrigation may be an option.
Make sure to check your irrigation system for leaks that are wasting water and to create a watering plan that corresponds to your irrigation requirements.
Consume Water Only When Necessary Considering watering your lawn and garden less frequently in the mornings or late at night when evaporation is lowest, you can save money on your water bills.
Once your septic tank has been repaired or pumped, it is important to save water in order to extend the tank’s lifespan.

Understanding Septic Tank Volume
- A septic system that is undersized results in wastewater backing up. Your tank should be able to manage 95 liters of wastewater per person, per day
- Else, it will fail. The presence of a strong stench, water backing up, and an increase in water use are all indicators of trouble. A concrete septic tank is frequently the most cost-effective alternative.
Get quotations from as many as three professionals! Enter your zip code below to get matched with top-rated professionals in your area. Septic systems enable homeowners in remote locations to maintain a contemporary way of life. They treat all of the nasty wastewater that comes out of our toilets, sinks, and washing machines before safely releasing it into the environment. However, you must select a septic tank that has the appropriate volume for your residence. This information will assist you in making an informed decision to keep your home’s wastewater where it belongs: out of sight.
How Septic Tank Volume Works
A septic system is a structure installed beneath the earth that processes wastewater from a residential building. Their use is particularly prevalent in rural areas where there is limited access to centralized sewer systems. A septic tank and a drainfield are both components of the septic system. The tank is responsible for separating materials such as oil, grease, and sediments from wastewater. The treated sewage, which is referred to as “effluent,” is progressively released into the surrounding environment by the system.
It’s possible that if you buy a tank that is too small, it will not be able to handle the volume of wastewater that your home generates, and the wastewater may begin to back up into your home or your yard.
How to Calculate Septic Tank Size
So, how much of a septic tank do you require? Multiply the total number of people living in your family by 95 to get an idea of how much septic tank daily liter volume you would require. Another way of looking at it is to imagine that you’re sharing a house with three other individuals. You’d need to figure out how much wastewater is produced on a daily basis by each individual and multiply that figure by four to figure out how much capacity you’d need from your septic system. To make an approximate estimate, use the following list of daily average wastewater production to guide your calculations:
- 1 liter per person for the bathroom, 6 liters for the laundry and dishwasher, 1 liter per person for cooking, and 3 liters per person for everything else Per individual, a total of 95 liters
As a result, for a four-person family, a septic system capable of handling 380 liters per day of wastewater output (4 x 95 = 380) would be required.
Signs You Need to Replace Your Septic System
Adobe Stock image courtesy of senssnow What are the signs that it’s time to rebuild your septic system? Because a new septic system may cost upwards of $20,000, it is evident that you want to postpone replacing your system if at all possible. However, there are four primary signs to look out for that indicate you should consider replacing it.
Your Water Consumption Has Increased
The presence of new family members in your home might cause your water use to grow drastically, which is a clear indication that it’s time to upgrade your septic system. You should first determine whether or not your present septic system has the ability to manage the extra water flow.
Water Is Backing up in Your Yard or Home
In the event that you see standing water in your yard or that water is backing up in your toilets and sinks, it is likely that your septic system is overburdened and has to be replaced.
However, before assuming that there is a clog rather than a lack of volume, check to see whether there is a clog. Preventative maintenance is also crucial; it is possible to avoid septic backups by performing regular maintenance.
Tubs and Sinks Take a Long Time to Drain
Even though the water isn’t backing up, if you’ve observed that a sink or a tub is taking an inordinate amount of time to drain no matter how much drain cleaner you pour down there, it may be due to a problem with your septic system rather than a blockage in your pipes, see a professional.
You Notice a Strong Odor
Wastewater is, to put it mildly, nasty, so before you notice any of the other indicators listed above, you may be overcome with a tremendous stink that knocks you off your feet. The presence of this stench, which is particularly prominent around the location of the septic tank and drainfield, is an indicator that wastewater is seeping out of your system and onto your yard, according to the EPA. It is an issue that must be addressed immediately to avoid it becoming worse.
Concrete Septic Tanks Are Probably the Best Option
Steel, plastic, and fiberglass are all common materials for septic tanks, but they can also be made of other materials. However, due of its durability, old-fashioned concrete is probably your best choice in this situation. In comparison to wood, concrete is a considerably stronger material that will hold its shape even after years of use. Moreover, they can be more effective at maintaining heat, which promotes the development of bacteria that break down the waste that enters the tank and resulting in a cleaner effluent that drains into your area of operation.
How to Find Your Septic System
It’s critical to examine your septic tank on a regular basis to verify that everything is running well. How do you proceed if you are unsure of the location of your septic system? That’s alright, because there are a couple other methods to locate it. In this case, you may look at the “as constructed” design of your home, which should show the placement of the septic system. Alternatively, you might do a visual search of your yard to see if any lids or manhole covers can be discovered. As a last option, you can call a septic system service provider in your area to assist you in locating one.
Why is lots of water bad for septic, and how can I take long showers without hurting it?
The only issue I can see is an over-saturation of the ground, which will result in the earth being unable to absorb any of the effluent as it is intended to do. The fact that you have lived there for 6 months and have not noticed any indicators of difficulties at the leaching field suggests that there should not be a problem. Bathroom and kitchen sinks and bath tubs are expected to be constructed for the quantity of water that will be poured into the leaching field from the entire house. I’ve had a septic system for the past 24 years and have never had any problems with it.
It is a 1989 house with three bedrooms and one and a half bathrooms.
Water on its own will have no effect on the situation.
Although I’ve worked on properties where the owners insisted on having a trash disposal, they must be dedicated to pumping it out on a regular basis since, in a sense, it is serving as a holding tank, which they must do on a regular basis.
Water Usage and Your Septic System
The quantity of water you put into your septic tank on a daily basis is one of the most important factors that influences how effectively it functions. Because septic systems have a limited capacity, your tank can only hold so much water at a time. A larger home might soon overflow a smaller septic tank if they consume a lot of water on a regular basis. It is important to understand how your household activities influence your septic system as the size and composition of your family grows and changes.
Planning your water usage can help your septic system
Human waste may be treated quite efficiently with the help of a septic system. The fact that they are small and very basic means that they are less expensive than centralized sewer systems. In the wastewater layer, there is biological activity that provides for safe drainage into the earth underneath it. The tank keeps both the scum layer and the sediment (or sludge) layer until they are cleaned out by a professional tank cleaner during routine tank maintenance. Inadequate watering of the septic tank may cause it to malfunction and fail to perform its biological functions properly.
- This statistic covers activities such as bathing, cooking, flushing the toilet, cleaning, and doing laundry.
- If your septic tank is tiny – say, 800 gallons – you can see that the majority of the water in the tank will not remain in the tank for lengthy periods of time.
- According to parameters such as the number of beds in the house, several jurisdictions restrict the size of a septic tank to a certain minimum.
- The technique of designing your septic system to handle “peak” water demand is a smart one to follow.
- If the capacity of your septic system is a worry for your house, there are steps you may do to reduce water consumption.
- Showerheads, faucets, washing machines, and toilets with low flow rates can all help to lower the amount of water that enters your home’s septic tank by a substantial amount.
- You may plan your water consumption in advance to prevent producing a “peak demand” in your home.
- Laundry.
- If you want to avoid flooding your septic tank, try to limit the amount of loads you do every day.

What Size Septic Tank Do I Need?
Septic systems are used for on-site wastewater management, and they are located right outside your home. Perhaps your building project is located outside of a municipal service area, or you just like the notion of conducting wastewater treatment on a private basis. The optimum septic tank size is critical to the efficient operation of any septic system, regardless of the purpose for its installation. The percolation test, also known as a perc or perk test, as well as local codes, will be used to establish the position and quantity of field lines to install.
Do I require a large or small septic tank?
Why Septic Tank Size Matters
It is your septic tank’s job to collect and treat all of the water that exits your home through your toilets, showers, laundry, and kitchen sinks. For as long as 24 hours, the water may be kept in the tank, which also serves as a separation chamber where solids are removed from liquids in the process. When it comes to separating particles from liquids, the retention time is critical. The presence of bacteria in the tank aids in the breakdown of sediments. The size of the tank has an impact on how successfully the system can separate and break down the waste materials.
Although it might seem logical to believe that a larger tank is preferable, a tank that is too large for your water usage can interfere with the formation of germs.
Calculation by Water Usage
There are a variety of formulas that can be used to calculate the size of the septic tank that is required for your property. The most precise and dependable method is to measure water consumption. The size of the septic tank that is required is determined by the amount of water that will be handled and then dispersed into the field lines of the property. It should be noted that the minimum capacity tank permitted in many regions of the nation is 1,000 gallons. The following is a recommended tank size based on the total amount of water used by your household.
- 900 gallon tank for up to 500 gallons per day
- 1,200 gallon tank for up to 700 gallons per day
- 1,500 gallon tank for up to 900 gallons per day
- Tank holds up to 1,240 gallons per day
- Tank capacity is 1,900 gallon.
Calculations By House Size
The number of bedrooms in your home, as well as the square footage of your home, are less precise guides for determining the size of your tank. The maximum number of bedrooms that may be accommodated by a 1,000 gallon septic tank is two. It’s difficult to say due to the fact that water consumption varies depending on your situation. These estimates are based on the assumption that all bedrooms will be occupied, and the anticipated water consumption is based on this assumption. It is impossible to do these calculations if you live alone in a three-bedroom house.
These estimates are necessary since a new owner may choose to occupy all of the bedrooms, and the tank must be large enough to accommodate the increased demand. The suggested tank sizes are listed below, according to the number of bedrooms in the house.
- Three bedrooms under 2,500 square feet: 1,000 gallon tank
- Four bedrooms under 3,500 square feet: 1,200 gallon tank
- And five or six bedrooms under 5,500 square feet: 1,500 gallon tank
- One or two bedrooms under 1,500 square feet: 750 gallon tank
- Three bedrooms under 2,500 square feet: 1,000 gallon tank
Estimated Cost
Similarly to the cost of any other commodities or services, the price might vary significantly based on where you reside and the current market circumstances. Let’s pretend you’re going to install a concrete septic tank for the sake of planning your project. These are by far the most prevalent, and they have a somewhat lengthy life span. The cost of a typical 1,000-gallon septic tank is between $500 and $700 dollars. The cost of upgrading to a 1,250-gallon tank will be at least $100 more. After three to five years, depending on the size of the tank, you could anticipate to have a cleaning job to do.
If you’re debating between two different tank sizes, knowing your financial constraints might assist you make your ultimate selection.
Although your contractor should be able to assist you in sizing your tank, understanding how to roughly determine your size requirements will help you anticipate how much you’ll need and how much you’ll spend on your tank.
How Your Septic System Works
Underground wastewater treatment facilities, known as septic systems, are often employed in rural regions where there are no centralized sewage lines. They clean wastewater from residential plumbing, such as that produced by bathrooms, kitchen drains, and laundry, by combining natural processes with well-established technology. A conventional septic system is comprised of two components: a septic tank and a drainfield, often known as a soil absorption field. It is the septic tank’s job to decompose organic matter and to remove floatable stuff (such as oils and grease) and solids from wastewater.
Alternate treatment systems rely on pumps or gravity to assist septic tank effluent in trickling through a variety of media such as sand, organic matter (e.g., peat and sawdust), constructed wetlands, or other media to remove or neutralize pollutants such as pathogens that cause disease, nitrogen, phosphorus, and other contaminants.
Specifically, this is how a typical conventional septic system works:
- All of the water that leaves your home drains down a single main drainage pipe and into a septic tank. An underground, water-tight container, often composed of concrete, fiberglass, or polyethylene, serves as a septic system’s holding tank. Its function is to retain wastewater for a long enough period of time to allow particles to sink to the bottom and form sludge, while oil and grease float to the surface and produce scum. Sludge and scum are prevented from exiting the tank and moving into the drainfield region by compartments and a T-shaped outlet. After that, the liquid wastewater (effluent) exits the tank and flows into the drainfield. The drainfield is a shallow, covered hole dug in unsaturated soil that serves as a drainage system. Porous surfaces are used to release pretreated wastewater because they allow the wastewater to pass through the soil and into the groundwater. In the process of percolating through the soil, wastewater is accepted, treated, and dispersed by the soil, finally discharging into groundwater. Finally, if the drainfield becomes overburdened with too much liquid, it can flood, causing sewage to flow to the ground surface or resulting in toilet backups and sink backups. Finally, wastewater percolates into the soil, where it is naturally removed of harmful coliform bacteria, viruses, and nutrients. Coliform bacteria are a kind of bacteria that may be found in the intestines of humans and other warm-blooded animals, with humans being the most common host. As a result of human fecal contamination, it is a sign of this.
The Guadalupe-Blanco River Authority has built an animated, interactive model of how a residential septic system works, which you can view here.
Do you have a septic system?
It’s possible that you’re already aware that you have a septic system. If you are not sure, here are some tell-tale symptoms that you most likely are:
- You make use of well water. In your home, the water pipe that brings water into the house does not have a meter. In the case of a water bill or a property tax bill, you will see “$0.00 Sewer Amount Charged.” It is possible that your neighbors have a septic system
How to find your septic system
You can locate your septic system once you have confirmed that you have one by following these steps:
- Taking a look at the “as constructed” drawing of your house
- Making a visual inspection of your yard for lids and manhole covers
- Getting in touch with a septic system service provider for assistance in locating it
Failure symptoms: Mind the signs!
A bad odor is not necessarily the first indicator of a septic system that is failing to work properly. Any of the following signs should prompt you to seek expert assistance:
- There are several signs of a faulty septic system, and not all of them are unpleasant odors. Any of the following signs should prompt you to seek professional help:.
What Size Septic Tank Do I Need
The size of an underground septic tank is referred to as its total volume handling capacity in this article, and it will be discussed in further detail later in this article. For additional information on above-ground septic tanks and systems, see our page on above-ground septic tanks. The minimum septic tank capacity requirements are determined by a variety of variables. State, county, and/or city regulations may specify permitted tank sizes, as well as tank materials and installation.
The size of the septic tank will vary depending on whether it is intended for domestic or commercial usage; in this section, we will cover residential use.
Shortly stated, the required size of a septic tank will be determined by the following factors: (1) the specific septic system type; (2) local government requirements; (3) the compatibility of the ground geology; and (4) the anticipated volume of wastewater depending on the size of the residence.
However, this is not true.
Furthermore, plastic septic tanks will not corrode, are weatherproof, are waterproof, are less expensive, are lighter, and are easier to build. They will also not float if they are constructed appropriately.
1) The Specific Septic System Type
There are seven different types of septic tank systems, and the size of the tank required will vary depending on the system you choose. The scope of this article does not allow for a comprehensive discussion of each system type and its associated size requirements. We are referring to traditional gravity-fed anaerobic septic systems in this context when we say “system type.” The anaerobic septic system is the most prevalent type of septic system, and it is the one that most people think of when they imagine a septic tank.
- The following systems are available: conventional, gravity-fed, anaerobic systems
- Above-ground septic systems
- Pressure systems
- Anaerobic systems
- Mound systems
- Recirculating sand or gravel filters systems
- Bottomless sand filters systems
If your septic tank system is anything other than a traditional, anaerobic system, the instructions in this page may not be applicable in their entirety to your situation.
2) Local Government Regulations
The laws for septic tanks imposed by local governments vary greatly across the United States. In part, this is due to the significantly diverse soil geography and water features that exist from state to state and can even differ by a few miles in some cases. In order to determine the appropriate septic tank size and the best position on the land for installation, it is essential to consult with local government rules first. Take, for example, theWastewater Treatment Standards – Residential Onsite Systemsdocument from the New York State Department of Health, which provides a comprehensive informational overview of codes, rules, and regulations frequently promulgated by governing bodies, as well as common terminology and definitions in the industry.
3) Suitability of the Ground Geology
The subterranean soil type has a significant impact on the efficacy of the system and, consequently, the size of the septic tank. This topic is highly tied to the rules of the local government. In most cases, it is related to the standards and recommendations of a designated authority that regulates septic tank installations, which is typically the department of health. In order to determine whether or not the ground is suitable for a septic tank system, a trained specialist must come out to the prospective installation site and conduct a series of tests.
A perc test will assess whether or not the subterranean soil is capable of handling and filtering septic tank effluent in an appropriate manner.
Whether you are hiring an experienced professional or doing it yourself, it is your obligation to contact your local oversight agency and arrange for perc tests and/or ground area evaluations to be performed.
The findings of the analysis and testing will determine whether or not the chosen site is suitable, as well as whether or not a certain septic tank system or size is required.
4) The Expected Volume of Wastewater
The typical amount of wastewater that will be generated and that the septic tank will be able to manage is the most essential factor in determining the size of the septic tank that is required. In a home with simply a septic system, all wastewater is disposed of in the septic tank unless a separate system for managing greywater is in place to handle the waste. In order to calculate and approximate these values for residential dwellings, business structures, and facilities, extensive study has been carried out.
Starting with a 1000-gallon septic tank for residential usage, the advice is to go from there.
Some experts propose adding an additional 250 gallons of septic tank capacity for each additional bedroom over three bedrooms.
This is frequently the case when considering the situation collectively for the entire household rather than individually.
Minimum Septic Tank Capacity Table
For further information on the minimum septic tank capacity dependent on the number of residential bedrooms, please see the following table:
| Number of Bedrooms | Minimum Septic Tank Size | Minimum Liquid Surface Area | Drainfield Size |
|---|---|---|---|
| 2 or less | 1000 – 1500 Gallons | 27 Sq. Ft. | 800 – 2500 Sq. Ft. |
| 3 | 1000 – 2000 Gallons | 27 Sq. Ft. | 1000 – 2880 Sq. Ft. |
| 4 | 1250 – 2500 Gallons | 34 Sq. Ft. | 1200 – 3200 Sq. Ft. |
| 5 | 1500 – 3000 Gallons | 40 Sq. Ft. | 1600 – 3400 Sq. Ft. |
| 6 | 1750 – 3500 Gallons | 47 Sq. Ft. | 2000 – 3800 Sq. Ft. |
Take note of the following in relation to the table above:
- As defined by the State of New York, the Minimum Liquid Surface Area is the surface area given for the liquid by the tank’s width and length measurements. The range of Drainfield Sizes is depending on the kind of groundwater present. The State of Michigan provides the above-mentioned drainfield recommendations, which might vary greatly depending on local standards and terrain.
Additional Thought: Can a Septic Tank Be Too Big?
In the absence of consideration for cost, it is reasonable to ask: “Can a septic tank be too large?” The answer is a resounding nay. As long as the septic tank is placed appropriately, it is impossible for a septic tank to be too large; the only thing that can happen is that it is too little. According to the majority of suggestions, constructing a larger-capacity septic tank is frequently the safer and more preferable solution. The following are the reasons behind this:
- With a bigger septic tank, you can adapt for changes in household consumption, such as those caused by parties or long-term guests. In the event that your family grows in size or you want to make improvements to your house, such as adding more bedrooms and bathrooms or installing new plumbing fixtures, having a bigger septic tank can save you the expense of installing a new tank.
Takeaways | What Size Septic Tank Do I Need
The septic tank size recommendations offered here are merely that: suggestions. They are built on a foundation of information gathered from government and academic sources. The actual size of the septic tank you require will vary depending on the factors discussed in this article. There is no “one-size-fits-all” solution when it comes to determining the appropriate septic tank size for your property. There is a great deal of variation depending on where you reside. With addition to providing a basic insight into the septic tank and system size that may be most suited to your application, the providedMinimum Septic Tank Capacity Tablecan also assist in cost estimations.
Before beginning any septic tank installation project, check and double-check with the state, city, or local county’s agency that is in charge of septic tanks, soil testing, and permissions.

Tips For Keeping Your Septic Tank Running
The septic tank is a septic tank. It’s one of the most important pieces of equipment in your house — yet it’s also one of the most mysterious. Even though it might be tough to comprehend something that cannot be seen, understanding your septic tank and how it works is essential. The septic tank is where all of the wastewater from your house, including that from your kitchen, bathrooms, and even laundry rooms, is dumped. We’ve included a quick description of the operation of your septic system, as well as some suggestions for maintaining it in good operating order.
- The tank itself, as well as the drain field, are the two primary components of the septic system.
- Upon entering, solid components are classified as either scum or sludge, depending on how much of them there are in total.
- Within the tank, bacteria break down scum and sludge, and the separated water is sent through filters before entering the drain field.
- Tips for keeping your septic system in good working order Reduce your water consumption to a bare minimum.
- When there is an excessive amount of water flowing into the system, polluted water might escape from the tank and into the drain field.
- Water use by a single person every day amounts to 70 gallons, which may be surprising, but is an accurate reflection of the situation.
- Toilets: toilets account for 25-30 percent of the total amount of water consumed by a home. Toilets that are more recent in design consume less water than older models. Give us a call right now if your home is equipped with out-of-date toilets! In the long run, your septic system will be grateful to you.
- Sinks: Consider all of the water that goes down your sink every day that isn’t being used. When cleaning dishes, washing their hands, or brushing their teeth, it is usual for homes to leave their water running unattended. Take the initiative and make a change! Make use of the water in your sink just when you need it.
Keep an eye on what you dump down your drains. It is critical to consider what goes down your drains before flushing it. If you find yourself second-guessing an item, it is likely that it is not intended to be flushed down the toilet.
- Grease: While putting grease down your drain may seem like a reasonable choice, it is not recommended. Using grease to clean your pipes and drain field has the potential to clog them! It sounds like something out of a nightmare
- Due to our familiarity with flushing toilet paper down our toilets, we have a propensity to believe that comparable goods such as tissues or wet wipes are also safe to flush. This is because the microorganisms in your septic tank are unable to break down these materials, and they will most likely continue floating in your tank.
Make an appointment for a standard checkup. Septic tanks holding 1,000 gallons or fewer need to be serviced every five years or less. For septic tank maintenance, call us at 804-758-4314 to schedule an appointment with a Miller’s specialist.
What do I do if My Septic Alarm is Going Off?
In the event that your septic alarm goes off, it may surely create some anxiety and uncertainty; and if you happen to be experiencing this right now, then you’ve arrived to the correct location! Don’t be concerned; it does not necessitate urgent action. Instead, take your time to go through this full essay so that you will be prepared to act now or in the future if the situation arises. What Septic Systems Are and How They Work The alarm works in conjunction with the septic system to alert you when the water level within the pump tank has increased to an unsafe level or has decreased to an unsafe level.
The timer is in charge of regulating the time intervals during which the pump is permitted to pump wastewater into the drainage system.
Thus, during periods of excessive water use, the drain field is kept from getting overflowing, which might cause damage to the drainage system.
A large amount of water is injected into the system in between pumping cycles for whatever cause, and the water has nowhere else to go but back into the system’s pump tank.
Depending on how much water was and continues to be put into the system and how the pump is set up to operate on a timer, it may take many pumping cycles until the water levels are returned to normal. Causes of the alarm going off in the first place
- There is an excessive amount of water being put into the septic system. This is the result of excessive water use, which might be caused by multiple loads of laundry, an excessive quantity of dishwashing, or a disproportionate number of long showers.
- Somehow, groundwater is making its way into the system. If there is an excessive amount of standing water surrounding the septic tanks, whether generated by rain or another source, the water may seep into the tanks and cause the internal water level to rise.
- It’s possible that one of the components of the septic system is malfunctioning. If anything goes wrong with your system — including the pump and floats — the alarm and timer will go off and the septic system will stop working correctly.
The Best Thing to Do If Your Alarm Goes Off Alternatively, if you hear an alert, you should press the red button or turn on the alarm box. The alarm will be turned off as a result of this action. There should be a red light and a green light on the alarm box, which should be situated someplace on the unit. The green light indicates that the alarm is operational and should be left on at all times. It is shown by a red light if the alarm is getting a signal from the pump tank indicating that the water level is increasing above or decreasing below what is expected.
- If the breaker occurs to be tripped, look around the septic tanks to see if there is any standing water.
- It is possible that the red light on the alarm box will go out on its own after allowing the septic system to operate for a couple of pump cycles (which should take approximately 10-15 hours).
- If the red light turns off, it signifies that the system is operating properly and that it only needs to catch up with the extra water that has overflowed into the storage tank.
- To be clear, an alarm signal from the septic system does not always imply that sewage is about to back up into the house right away.

Help! My Septic Tank is Full!
Posted on a regular basis We receive a lot of calls concerning septic tanks that are “full.” But what does the term “full” truly imply? A septic tank should always be “filled” to its normal liquid level, which is the level at which the effluent exits the tank and flows to the absorption area, according to the manufacturer. On average, this typical liquid level is between 8″ and 12″ below the tank’s maximum capacity, depending on the model (see picture at right). If the liquid level is near the bottom of the outflow pipe, it is reasonable to believe that the absorption area is receiving the wastewater generated by the home.
If the tank is overflowing, it is typically a sign that there is a problem with the absorption area.
Plumbing or septic issue?
We get a lot of calls from folks who want us to pump their tank because they claim it is full.usually because they are experiencing troubles.
However, there are situations when the plumbing is the source of the problem. What is the best way to determine if an issue can be resolved by your septic maintenance provider or a professional plumber?
Check the cleanout
If the problem is caused by backup in the house, we recommend that you check your cleanout between the house and the tank (if one is present and accessible) to see if there is any backup in the cleanout (which is typically a 4″ PVC pipe with a removable cap). If the problem is caused by backup in the house, we recommend that you check your cleanout between the house and the tank (if one is present and accessible) to see if there is any backup in the cleanout. If there is no backup in the cleanout, we normally recommend that you call a plumber since this implies that the wastewater from the home is not making it to the cleanout.
Afterwards, you may check to see if the liquid level in the septic tank is normal or excessive by removing the lid(s) of the tank and looking inside.
If it is overflowing, you may be dealing with more serious problems (i.e.
Till you have a cleanout, your odds of requiring the services of either a plumber or a septic firm are 50/50, and you won’t know unless one of the two comes out to inspect the situation for you.
Check for smells
A foul odor in the house is typically indicative of a problem with the ventilation or plumbing. Unless you are having backup inside the house or septic system difficulties outside the house, we recommend that you consult with a plumber for assistance.
Signs of a larger problem
After being drained out, a septic tank would normally refill to its regular liquid level within a few days to a week, depending on the size of the tank and the number of people living in the property. As soon as the tank has been refilled to its usual liquid level, effluent can begin to flow back into the absorption area again. The fact that the septic tank is “overfull” may indicate a more serious problem with the entire system (see picture at right). If you are experiencing this problem, draining out your septic tank may provide some temporary respite, but it is unlikely to provide long-term relief.
