Septic Tanks vs Onsite Wastewater Treatment: Clearing Confusion (Guide)

Discover the Surprising Differences Between Septic Tanks and Onsite Wastewater Treatment in this Comprehensive Guide.

Step Action Novel Insight Risk Factors
1 Determine the type of onsite wastewater treatment system suitable for your property. Onsite disposal systems are designed to treat and dispose of wastewater on the same property where it is generated. Poor soil conditions, high water table, and limited space can limit the installation of certain systems.
2 Conduct a percolation test to determine the soil’s ability to absorb wastewater. A percolation test measures the rate at which water drains through the soil. Poor soil conditions can lead to system failure and contamination of groundwater.
3 Choose between a septic tank or an aerobic treatment unit (ATU). A septic tank is a simple, low-maintenance system that relies on anaerobic digestion to treat wastewater. An ATU uses aerobic digestion to break down organic matter and requires more maintenance. Improper maintenance of a septic tank can lead to system failure and contamination of groundwater. An ATU requires more maintenance and can be more expensive to install.
4 Install a drain field or soil absorption system to dispose of treated wastewater. A drain field is a network of perforated pipes that distribute treated wastewater into the soil. A soil absorption system uses a bed of gravel or other porous material to distribute treated wastewater into the soil. Poor soil conditions can lead to system failure and contamination of groundwater.
5 Install an effluent filter to prevent solids from leaving the septic tank or ATU. An effluent filter traps solids and prevents them from clogging the drain field or soil absorption system. Failure to install an effluent filter can lead to system failure and contamination of groundwater.
6 Consider greywater recycling to reduce water usage and wastewater generation. Greywater recycling involves treating and reusing wastewater from sources such as sinks, showers, and washing machines. Improper treatment of greywater can lead to health hazards and contamination of groundwater.
7 Consider connecting to a sewage treatment plant if available. A sewage treatment plant is a centralized system that treats wastewater from multiple properties. Connection fees and ongoing maintenance costs can be expensive.

Note: It is important to follow local regulations and obtain necessary permits before installing an onsite wastewater treatment system.

What is a Percolation Test and Why is it Necessary for Onsite Wastewater Treatment?

Step Action Novel Insight Risk Factors
1 Dig a hole The percolation test measures the rate at which water is absorbed by the soil The hole should be dug in an area where the effluent disposal area will be located
2 Fill the hole with water The water level should be measured and recorded The water level should not be allowed to drop below 2 inches during the test
3 Wait for the water to drain The time it takes for the water to drain from the hole is recorded The test should not be conducted during wet weather or when the soil is frozen
4 Measure the drainage rate The drainage rate is calculated by dividing the volume of water by the time it took to drain The test should be repeated in at least two other locations to ensure accuracy
5 Determine the soil’s infiltration capacity The infiltration capacity is determined by comparing the drainage rate to the soil’s porosity and texture If the soil’s infiltration capacity is too low, it may not be suitable for effluent disposal
6 Evaluate the site’s suitability The results of the percolation test are used to determine the site’s suitability for onsite wastewater treatment If the site is not suitable, alternative wastewater management options must be considered
7 Comply with environmental regulations The percolation test is necessary to ensure compliance with environmental regulations Failure to comply with regulations can result in fines and legal action
8 Develop a wastewater management plan The results of the percolation test are used to develop a wastewater management plan that meets the needs of the site and complies with environmental regulations A well-designed plan can prevent groundwater contamination and septic tank failure

Soil Absorption Systems: A Natural Solution for Treating Household Waste on Site

Step Action Novel Insight Risk Factors
1 Determine soil type and percolation rate Soil type affects the ability of the soil to absorb and treat wastewater. Percolation rate determines how quickly the soil can absorb water. If the soil is too permeable, wastewater may not be treated properly and can contaminate groundwater. If the soil is too impermeable, wastewater may not be absorbed quickly enough and can cause backups.
2 Install septic tank A septic tank is a watertight container that holds wastewater from the home and allows solids to settle to the bottom while oils and grease float to the top. Septic tanks require regular maintenance and pumping to prevent buildup of solids and prevent overflow.
3 Install effluent distribution pipe The effluent distribution pipe evenly distributes wastewater from the septic tank to the drainfield. If the effluent distribution pipe is not installed properly, wastewater may not be distributed evenly and can cause backups or overflows.
4 Install drainfield The drainfield is a series of perforated pipes or chambers that allow wastewater to seep into the soil for further treatment. If the drainfield is not installed properly or if the soil is not suitable for a drainfield, wastewater may not be treated properly and can contaminate groundwater.
5 Allow natural processes to treat wastewater Anaerobic bacteria in the septic tank break down solids, while aerobic bacteria in the soil further treat the wastewater through the nitrogen cycle. If the septic tank is not maintained properly or if the soil is not suitable for a drainfield, wastewater may not be treated properly and can contaminate groundwater.
6 Monitor oxygen demand and BOD Oxygen demand and biochemical oxygen demand (BOD) are measures of the amount of oxygen required to treat wastewater. If oxygen demand and BOD are too high, it may indicate that the system is not treating wastewater properly and may require maintenance or repair.
7 Monitor nitrification Nitrification is the process by which bacteria convert ammonia to nitrate, which can be taken up by plants. If nitrification is not occurring, it may indicate that the system is not treating wastewater properly and may require maintenance or repair.
8 Regularly maintain and pump septic tank Regular maintenance and pumping of the septic tank is necessary to prevent buildup of solids and prevent overflow. Failure to maintain and pump the septic tank can lead to backups, overflows, and contamination of groundwater.

Soil absorption systems are a natural and effective way to treat household waste on site. However, it is important to properly install and maintain the system to ensure that wastewater is treated properly and does not contaminate groundwater. By following these steps and monitoring the system regularly, homeowners can enjoy the benefits of a natural and sustainable wastewater treatment system.

Common Mistakes And Misconceptions

Mistake/Misconception Correct Viewpoint
Septic tanks and onsite wastewater treatment are the same thing. While both systems treat wastewater on-site, septic tanks only separate solids from liquids while onsite wastewater treatment systems use additional processes to further treat the effluent before it is discharged into the environment.
Onsite wastewater treatment systems are more expensive than septic tanks. The cost of an onsite wastewater treatment system depends on various factors such as site conditions, soil type, and local regulations. In some cases, an onsite system may be cheaper than a septic tank due to its efficiency in treating wastewater and reducing maintenance costs over time.
Septic tanks do not require regular maintenance or pumping. Regular maintenance and pumping of a septic tank is crucial for its proper functioning and longevity. Neglecting this can lead to clogging, backups, and costly repairs or replacements down the line.
Onsite wastewater treatment systems are harmful to the environment. When designed properly and maintained regularly, onsite wastewater treatment systems can effectively remove pollutants from household water before releasing it back into the environment without causing harm to human health or natural ecosystems.
Only rural areas need septic tanks or onsite wastewater treatment systems. Both urban and rural areas may require these types of systems depending on their location relative to municipal sewer lines or other infrastructure that provides centralized sewage disposal services.
