What is a drainfield and how does it differ in septic tanks vs mound systems?
| Step | Action | Novel Insight | Risk Factors |
|---|---|---|---|
| 1 | A drainfield is a component of a septic system that is responsible for the final treatment and disposal of wastewater. | The drainfield is also known as a soil absorption field, leach field, or effluent distribution network. | Poorly designed or maintained drainfields can lead to groundwater contamination and environmental hazards. |
| 2 | In a septic tank system, the drainfield is typically a soil absorption field that allows the effluent to percolate through the soil and be treated by aerobic bacteria. | Aerobic bacteria require oxygen to break down organic matter and remove harmful pathogens from the effluent. | High percolation rates, compacted soils, and shallow water tables can all affect the performance of a soil absorption field. |
| 3 | In a mound system, the drainfield is elevated above the natural soil surface and consists of a sand or gravel bed that is designed to filter and treat the effluent. | Mound systems are often used in areas with poor soil conditions or high water tables. | Mound systems require regular maintenance and monitoring to ensure proper function and prevent system failure. |
| 4 | Mound systems may also use alternative drainfield designs, such as infiltrator chamber systems or drainage bed systems, to improve treatment and disposal of wastewater. | Infiltrator chamber systems use plastic chambers to distribute effluent evenly throughout the drainfield, while drainage bed systems use a layer of gravel or rock to improve drainage and treatment. | Alternative drainfield designs may be more expensive to install and maintain than traditional soil absorption fields. |
| 5 | Both septic tank and mound systems rely on the nitrogen cycle to break down organic matter and remove harmful pathogens from the effluent. | Anaerobic bacteria in the septic tank break down organic matter and convert it to ammonia, which is then converted to nitrate by aerobic bacteria in the drainfield. | Excessive nitrogen loading from septic systems can lead to environmental problems such as eutrophication and harmful algal blooms. |
| 6 | The performance of a drainfield can be affected by soil composition, water table depth, and percolation rates. | Soil composition can affect the ability of the soil to absorb and treat effluent, while high water tables or percolation rates can lead to system failure or environmental hazards. | Proper design, installation, and maintenance of a drainfield are essential to ensure proper treatment and disposal of wastewater. |
What is the importance of a percolation test when installing a septic tank or mound system?
| Step | Action | Novel Insight | Risk Factors |
|---|---|---|---|
| 1 | Conduct a site evaluation to determine the soil texture, structure, and porosity. | Soil texture and structure affect the infiltration capacity of the soil, which is crucial for the proper functioning of a septic system. | The site evaluation may reveal that the soil is not suitable for a septic system, which could lead to costly modifications or alternative solutions. |
| 2 | Perform a percolation test to determine the soil’s ability to absorb water. | The percolation test measures the rate at which water drains through the soil, which is an indicator of the soil’s ability to treat wastewater. | If the soil has a low infiltration capacity, it may not be able to adequately treat the effluent, leading to groundwater contamination and environmental impact. |
| 3 | Design the septic system based on the results of the site evaluation and percolation test. | The septic system design should take into account the soil’s permeability, water table depth, and drainage field requirements. | Poor septic system design can lead to effluent disposal issues, groundwater contamination, and environmental impact. |
| 4 | Install the septic system or mound system according to the design specifications. | Proper installation is crucial for the long-term functioning of the septic system and to prevent environmental impact. | Improper installation can lead to system failure, effluent disposal issues, and groundwater contamination. |
| 5 | Regularly maintain and monitor the septic system to ensure proper functioning. | Regular maintenance, such as pumping the tank and inspecting the system, can prevent system failure and environmental impact. | Neglecting maintenance can lead to system failure, effluent disposal issues, and groundwater contamination. |
| 6 | Dispose of effluent properly to protect water quality. | Proper effluent disposal is crucial to prevent groundwater contamination and environmental impact. | Improper effluent disposal can lead to water quality issues and environmental impact. |
Leach fields: understanding their function in sewage disposal for both types of systems
| Step | Action | Novel Insight | Risk Factors |

They are designed to treat and dispose of the effluent that comes out of the septic tank or mound system. | Failure to properly maintain the leach field can lead to groundwater contamination and environmental impact. |
| 2 | Know the components of a leach field | A leach field consists of a series of perforated pipes that are buried in trenches filled with gravel. The pipes are designed to distribute the effluent evenly throughout the field. | The soil composition and percolation rate are critical factors in determining the size and design of the leach field. |
| 3 | Understand the role of soil absorption | The effluent that comes out of the septic tank or mound system contains organic matter and nutrients that can be harmful to the environment. The soil in the leach field acts as a natural filter, removing these contaminants before they reach the groundwater. | Overloading the leach field with too much effluent can lead to clogging and failure of the system. |
| 4 | Know the types of bacteria involved in the process | The effluent that enters the leach field contains both anaerobic and aerobic bacteria. The anaerobic bacteria break down the organic matter, while the aerobic bacteria consume the nitrogen and other nutrients. | Using harsh chemicals or antibacterial soaps can kill the bacteria in the leach field, leading to system failure. |
| 5 | Understand the importance of effluent distribution | The effluent must be distributed evenly throughout the leach field to ensure proper treatment and disposal. This is typically achieved through the use of a distribution box or manifold. | Failure to properly distribute the effluent can lead to uneven treatment and premature failure of the leach field. |
| 6 | Know the permitting process | The installation of a leach field requires a permit from the local health department or environmental agency. The permit process typically involves a site evaluation to determine the suitability of the soil and percolation rate. | Failure to obtain the necessary permits can result in fines and legal action. |
| 7 | Understand the importance of maintenance | Proper maintenance of the leach field is critical to its long-term performance. This includes regular pumping of the septic tank or mound system, avoiding overloading the system, and avoiding the use of harsh chemicals or antibacterial soaps. | Failure to properly maintain the leach field can lead to premature failure and costly repairs. |

Common Mistakes And Misconceptions
| Mistake/Misconception | Correct Viewpoint |
|---|---|
| Septic tanks and mound systems are the same thing. | Septic tanks and mound systems are two different types of wastewater treatment systems. A septic tank is a basic system that separates solids from liquids, while a mound system uses sand or gravel to filter and treat wastewater before it enters the soil. |
| Mound systems are always better than septic tanks. | The choice between a septic tank and a mound system depends on various factors such as soil type, site conditions, local regulations, etc. While some sites may require a mound system due to poor soil quality or high water table, others may be suitable for a traditional septic tank installation. It’s important to consult with an expert to determine which option is best for your specific situation. |
| Mound systems require more maintenance than septic tanks. | Both types of systems require regular maintenance to function properly and avoid costly repairs in the future. However, since mound systems have additional components like pumps and filters, they may need more frequent inspections and cleaning compared to simple septic tanks without any added features. Proper maintenance can extend the lifespan of both types of systems significantly. |
| Septic tanks don’t work well in wet areas or near bodies of water. | While it’s true that certain site conditions like high groundwater levels or proximity to lakes/rivers can make installing a traditional septic tank challenging (or even impossible), there are ways around these issues such as using alternative drainfield designs (e.g., raised beds) or adding special features like effluent filters or aerobic treatment units that enhance performance in difficult environments. |
| Mound systems always cost more than septic tanks. | The cost difference between these two options varies depending on several factors such as size, location, materials used, labor costs etc., but generally speaking,mound installations tend to be more expensive than septic tanks due to the added components and specialized design requirements. However, it’s important to consider long-term costs as well since a properly installed and maintained system can save you money in repairs and replacements down the line. |
