Septic tanks are a critical component of rural and suburban homes that don’t have access to centralized sewer systems. Traditionally, these tanks have been known for their foul odor and maintenance issues. However, the modern septic tank design has undergone significant improvements that have made them an efficient and eco-friendly solution for managing household sewage. From plastic to concrete construction, to advanced filtering, these new designs have transformed the septic tank industry. In this blog post, we’ll discuss the latest innovations and features of modern septic tank design that has led to appreciable benefits for homeowners and a cleaner environment.

1. Enhanced innovative/alternative septic systems to prevent excess nutrients

Enhanced innovative/alternative septic systems are being developed to prevent excess nutrients, such as nitrogen, from entering the environment. These systems have shown promise in removing nitrogen from wastewater before it enters groundwater, estuaries, and ponds. EPA scientists are partnering with other organizations to implement a neighborhood-scale demonstration of these systems in the Barnstable Clean Water Coalition (BCWC). The IA septic system upgrades are being offered by BCWC to up to 40 homeowners in a Barnstable, MA neighborhood. Each system will be monitored for performance for approximately three years following installation. Groundwater monitoring wells located up- and downgradient from participating homes will be monitored to determine the total effects of IA septic systems on groundwater nitrogen levels. EPA scientists will conduct concurrent research on the social acceptability and user experience of IAs to inform outreach to potential future participants. Information gathered from focus groups of IA septic system adopters and non-adopters will be shared with stakeholders in the Cape Cod region and other areas seeking to better manage nitrogen from septic systems. [1][2]

2. Testing of new septic system designs for nitrogen removal

The United States Environmental Protection Agency (EPA) is partnering with various organizations to implement a neighborhood-scale demonstration of enhanced innovative/alternative (IA) septic systems that are designed to prevent excess nitrogen from entering estuaries and freshwater ponds in the Cape Cod region. These enhanced IA septic system designs have shown promising results for removing much of the nitrogen in wastewater before it enters surrounding groundwater, estuaries, and ponds. However, only a limited number of systems have been field-tested, and more installations and testing are needed to evaluate performance before they can be considered for broader use.

Acceptance of these systems by homeowners can depend on factors such as cost, aesthetics, perceived risks, and local ordinances. Excess nitrogen from septic systems and other human activities can threaten aquatic ecosystems, including estuaries and wetlands, by contributing to algae blooms, low dissolved oxygen, degradation of seagrass, and fish kills. The IA septic systems are designed to prevent excess nutrients from entering the Cape’s estuaries and freshwater ponds. EPA scientists will conduct concurrent research on the social acceptability and user experience of IAs to inform outreach to potential future participants. The study is part of a larger pilot project at EPA focused on evaluating promising interventions with a goal of reducing excess nitrogen in the Cape Cod region. [3][4]

3. Traditional septic systems contribute to excess nitrogen pollution

Traditional septic systems are commonly used in areas without a centralized sewer system. These systems usually consist of a buried water-tight container called a septic tank and a shallow covered soil absorption field called a drain field. However, these systems do very little to remove excess nitrogen from wastewater, which has resulted in nitrogen pollution in surrounding environments. Excess nitrogen from septic systems and other human activities can threaten estuaries, wetlands, drinking water sources, and freshwater ponds as they contribute to algae blooms, low dissolved oxygen, degraded seagrass, and impaired freshwater. This pollution problem has led to the development of new septic system technologies that are now available, able to remove nearly 90% of the nitrogen in wastewater, and address some issues in coastal areas with higher groundwater levels. These enhanced innovative/alternative septic systems are designed to prevent excess nutrients from entering the Capes estuaries and freshwater ponds. [5][6]

4. Neighborhood-scale demonstration project for improved septic systems

A neighborhood-scale demonstration project was initiated to showcase improved septic systems. The project aims to provide effective and affordable wastewater treatment solutions in areas where conventional centralized systems are impractical or too expensive. The demonstration involves the installation of innovative technologies that treat wastewater on-site and ensure environmental protection. These systems satisfy regulatory standards while also being more efficient and sustainable. This project is a great opportunity for homeowners and communities to learn about decentralized wastewater management and the benefits it provides. The demonstration project will also help promote the adoption of improved septic systems and push for their integration into design standards in the future. Ultimately, this initiative can assist in landfill diversion, energy conservation, and reduction in greenhouse gas emissions through the retention of valuable nutrients and water resources. [7][8]

5. Upgrades to innovative/alternative septic systems in Cape Cod region

In an effort to prevent excess nutrients from entering estuaries and freshwater ponds in the Cape Cod region, the EPA is partnering with local organizations to implement neighborhood-scale demonstrations of enhanced innovative/alternative (IA) septic systems. These IA septic systems have shown promise in removing much of the nitrogen in wastewater before it enters surrounding groundwater, estuaries, and ponds. However, more installations and testing are needed before they are considered for broader use. To evaluate the performance of the latest enhanced IA septic systems, up to 40 homes in a Barnstable neighborhood will have their traditional septic systems replaced with IA septic systems, capable of removing nitrogen from wastewater. These systems will be monitored for approximately three years following installation, and the data collected will be used to inform future outreach to potential participants. [9][10]

6. Monitoring of IA septic system performance for nitrogen removal

In order to evaluate the effectiveness of innovative/alternative (IA) septic systems in removing excess nitrogen from wastewater, a monitoring process has been put in place. This monitoring will take place over a period of approximately three years following installation and will involve the use of groundwater monitoring wells. These wells will help to determine the total effects of IA septic systems on groundwater nitrogen levels both up and downstream from participating homes. EPA scientists will also conduct research on the social acceptability and user experience of these systems to provide insights to stakeholders in the Cape Cod region and other areas. The data gathered from this monitoring process will provide important information on the performance of IA septic systems, their cost-effectiveness, and their impact on groundwater nitrogen levels. This information will be useful for developing and implementing strategies to reduce excess nitrogen and improve water quality in sensitive areas. [11][12]

7. Focus groups to inform outreach for future IA septic system adoption

The EPA is conducting a neighborhood-scale demonstration of innovative/alternative (IA) septic systems to prevent excess nutrients such as nitrogen from entering estuaries and freshwater ponds in the Cape Cod region. However, homeowners’ acceptance of IA systems can rely on social factors, cost, and perceived risks. To better understand potential future participants’ outreach, the EPA and partners are conducting focus groups with IA septic system adopters and non-adopters. The information gathered from these focus groups will be used to inform stakeholders in the Cape Cod region and other areas looking to better manage nitrogen from septic systems. The IA septic systems are designed to prevent excess nutrients from entering the Capes estuaries and freshwater ponds, and performance measures and cost effectiveness information for the deployed IA septic systems will be evaluated in the demonstration project. Groundwater monitoring wells will be monitored to determine the total effects of IA septic systems on groundwater nitrogen levels. [13][14]

8. Pilot project to reduce excess nitrogen in Cape Cod region

A pilot project is underway to reduce excess nutrient loading in Cape Cod’s waters. The project aims to develop a watershed-level approach to decrease the amount of excess nitrogen in the Three Bays Watershed. One part of the project will replace traditional septic systems with enhanced nitrogen-reducing septic systems in up to 20 houses. These enhanced innovative/alternative (IA) septic systems will be monitored collectively for nitrogen removal performance for approximately three years following installation. Concurrently, EPA scientists will research the factors that influence social acceptance of these nitrogen-reducing systems. The end goals of the demonstration project include quantifying nitrogen reduction and communicating lessons learned to local, state, regional, and federal partners in watersheds similarly compromised by legacy septic systems. [15][16]

9. Performance measures and cost effectiveness of IA septic systems

One promising solution for removing excess nutrients like nitrogen from wastewater before it enters the environment is enhanced innovative/alternative (IA) septic systems. These septic systems have shown efficient nitrogen removal in wastewater, but more testing and installations are necessary to determine their effectiveness and cost efficiency. Homeowners’ willingness to adopt these systems might be influenced by factors like cost, aesthetics, perceived risks, and local regulations. To evaluate the performance and cost-effectiveness of IA septic systems, the US Environmental Protection Agency (EPA) has partnered with other agencies to implement a neighborhood-scale demonstration project in a high-density housing Barnstable, Massachusetts. The project involves the replacement of up to 40 traditional septic systems with novel IA septic systems that remove nitrogen from wastewater and will be monitored for about three years. Results from this pilot project will inform stakeholders in the Cape Cod region and other areas facing similar challenges with traditional legacy septic systems. [17][18]

9. Performance measures and cost effectiveness of IA septic systems

The enhanced innovative/alternative (IA) septic systems are designed to prevent excess nutrients from entering estuaries and freshwater ponds by removing nitrogen from wastewater before it enters surrounding groundwater, estuaries, and ponds. The IA septic system upgrades are being offered to homeowners in a Barnstable, MA neighborhood. Each system will be monitored for nitrogen removal performance for approximately three years following installation. Groundwater monitoring wells located upstream and downstream from participating homes will be monitored to determine the total effects of IA septic systems on groundwater nitrogen levels. The project aims to provide performance measures and cost effectiveness information for the deployed IA septic systems and will evaluate the impact of the systems on groundwater nitrogen levels. This information will enable local, state, regional, and federal partners to implement similar IA septic systems in other areas compromised by traditional legacy septic systems. [17][18]

If your property contains a septic system, you should know its location. Doing so can help avoid damaging the tank by adding structures or planting deeply-rooted plants near it.

Additionally, investing now will save you money in the long run. Damage to power lines could result in fines or costly repairs later on.

Look for a Map

If you need to locate the exact location of your septic tank, there are several methods. Check your property records; usually, the deed and building permit/design plans will contain details on its presence.

You can also consult municipal records or ask your previous owner where the septic tank is situated. While this will give you a good indication, it may not be precise enough.

Another option is to follow the sewer pipes that exit your home and into your yard. These typically 4-inch metal lines run from your main drains to a septic tank.

To locate these pipes, insert a thin metal probe into the ground near where they leave your house. Insert it every two feet and you should feel it hit a flat concrete or fiberglass surface – this is an indication that you’ve taken the right turn.

Next, search your lawn for any dips or small hills that might indicate a buried septic tank. Many are installed in such a way as not to draw attention, but over time these areas may become hard to distinguish from the rest of your landscaping due to grass growth.

Once you’ve identified these locations, take a walk around your property to search for more clues. These could include raised or sunken areas that indicate a shallow-buried septic tank, as well as areas with lush growth.

It’s wise to keep an eye out for bald spots without grass growth, which could indicate a septic tank beneath your soil. This is especially useful in wintertime when snowmelt acts as an effective indicator of where your septic tank lies.

Finally, consider purchasing an electronic transmitter and flushing it down your toilet to track where the signal is strongest. While this isn’t a guarantee for finding your tank, it could be useful if other clues don’t work.

Follow the Sewer Pipes

If you’re uncertain where your septic tank is, follow the sewer pipes that carry waste from your home to a main sewer main under the street. Usually, this will lead directly to your septic tank.

You can use a map of your house to make this determination. The map will indicate the position of your septic tank, distribution box and absorption field with respect to your home. Having this info handy can be extremely beneficial when performing future maintenance and repair on your system.

Septic systems are underground, closed-system sewage treatment and disposal systems designed for treating wastewater from residential or commercial buildings. The septic tank, drain field and distribution box filter out waste before it’s buried in the soil beneath them.

Your septic tank requires regular maintenance and pumping in order to stay functioning optimally. According to manufacturer instructions, you should have it pumped every 3-5 years for optimal effectiveness.

Septic tanks often become full due to accumulation of solid waste and liquids not broken down by your system, leading to backed-up or slow draining drains in your home.

In some instances, wastewater from your home may build up and blockage in your drain field – located nearby your septic tank. This could be a serious issue if the tank is overfilled as it will prevent the drain field from emptying properly.

Regular pumping of your septic tank is recommended, as this helps prevent the buildup of wastewater that could eventually clog the system and require costly repairs or replacement. Furthermore, avoid using certain types of sanitary materials like diapers or wipes which could clog your septic tank.

If your septic tank is overfilled, you may need to have it pumped or some soil removed so the drain field can empty properly. This usually is a simple and cost-effective procedure.

Another option is having a professional plumber dig up soil to pinpoint where your septic tank will be situated. They can then map out its exact location on a map and install risers for future convenience.

Look for Clues

Many counties maintain records of the installation of septic tanks at each property, and these maps should include schematics that demonstrate its precise placement as well as measurements to help locate it. Remember that landmarks may change over time, so don’t rule out a spot just because there are more shrubs or trees nearby.

If you live in a rural area, chances are your home is serviced by a septic system. If not sure, ask some of your neighbors; if they all have one, then chances are good that yours does too.

You can also search for signs of septic tank presence by taking a walk around your property. Look for small hills and dips in the ground that might indicate its presence.

Other indicators to watch out for include unexplained wet spots, foul odors and several pipes poking out of the ground. If you’re having difficulty locating the tank, mark its location with a marker in your yard so that you can easily locate it when needed.

When placing a marker, make sure it’s heavy enough to resist being blown away in windy conditions. You could also place a flag or other decorative item on the ground as an additional way of marking your location.

A soil probe is another useful tool for locating your tank. These small metal tubes penetrate through the soil to quickly detect anything buried underground.

Septic tanks typically lie six to four feet underground, so to check for septic tanks in your yard, insert a soil probe every two feet starting from where the sewer pipe leaves your home.

Once you’ve identified the sewage line, follow it straight out. Your septic tank should be located between five and 25 feet from your house.

If you’re having trouble locating your septic tank, try using a drain snake to break up any obstructions along the way. Be mindful not to twist it into the sewer pipe as this could damage either it or the tank itself.

Once you’ve identified your septic tank, it’s essential to know its location so you can service it as necessary. Furthermore, avoid planting any plants with deep roots near the tank as these could clog it and cause issues.

Create Your Own Map

Constructing a map to help locate your septic tank when you don’t know its location can be invaluable. This is especially crucial if you plan to do any landscaping or other work that involves digging. Furthermore, having this information handy makes it simpler for a future homeowner to locate the tank should they purchase your home and need to make repairs or renovations.

To locate your septic tank, start by locating where your main sewer line exits your home (Figure 1). This is usually the largest pipe in the house and may have a cleanout access hole that you can use to locate it. You may purchase a soil probe which can stick into the ground and follow this pipe’s path.

Once you’ve identified this line, follow it until it takes you away from the house and into your yard. While this may not always lead to your septic tank, it’s often a good starting point.

When wastewater from your house’s plumbing drains enters a septic tank, which is typically made of concrete (Figure 4.2). Here, lighter solids like grease and soap float to the top while heavier materials settle at the bottom.

Bacteria in the septic tank break down solid waste to simple nutrients, gas and water. Because these beneficial bacteria require oxygen to survive, it’s essential not to add any chemicals or substances into the system which will disrupt their action and lead to environmental issues.

It’s wise to inspect the scum and sludge levels in your septic tank at least once annually. To do this, use a clear plastic tube with a check valve on one end.

Another option is to invest in a septic tank locator kit with an electronic transmitter and receiver, which you can flush down your toilet to locate the tank and its location. These kits can usually be found at many hardware stores at relatively low costs.

Once you’ve located your septic tank, take note of its location so it can be quickly and easily identified in the future. Additionally, creating a map of all septic tanks on your property might be beneficial in case someone needs to locate them later.
