How Do You Test A Septic System

How Do You Test A Septic System – In rural areas of developed countries, almost all domestic wastewater is disposed of and partially treated using surface septic systems. In the US and Canada, about 25% of households have a septic system for wastewater treatment. These systems typically fail after 20 to 30 years of service, which equates to more than a million septic system failures each year in the US alone.

Standard septic system technology works by settling the solids in the wastewater stream in an anaerobic environment. Failure to maintain or increase the planned load on the system dramatically increases the risk of failure. A suboptimal septic system can lead to the development of potential health hazards and contamination of local water supplies.

Current decisions to replace or repair suboptimal septic systems can be a significant cost burden for the homeowner. The ClearPod solution is designed as a simple, reliable solution to improve and restore the performance of existing septic systems.

Septic Soil & Percolation Tests

The technology is designed as a retrofit solution to improve septic system efficiency. Using an aerobic fixed film treatment process, the system is designed to increase system performance by reducing soluble BOD concentrations in the effluent.

In further scientific validation of the ClearPod technology, we recently installed a test system at the Barnstable Test Facility (Massachusetts, USA). For this study, we compared the performance of a control septic system to determine performance standards for the updated ClearPod solution. The results below describe the first 3 months of operation.

After an inoculation period of approximately 30 days, the Clear Pod technology clearly shows stable septic effluent with less than 30 mg/L BOD and TVD.

A second test for the system is to calculate the effect of effluent flows from the test and control system on leech field performance. This “underwater” survey is designed to predict hydraulic flow blockages through the leech field, indicating when a septic system failure may occur.

Soil Test Pits For Septic System Design

Results obtained today can clearly demonstrate improved hydraulic (fluid) flow through the loop field attached to the ClearPod system. This demonstrates the benefits of the ClearPod system for a septic system affected by poor drainage and ponding. As you know now, septic systems are a bit more complicated than they were 10 or 20 years ago.

Private sewer regulations in Alberta go through a codification cycle approximately every 5 years … and changes occur with each code cycle. For example, the 2009 coding cycle was huge. For example, requirements for septic tank sizes have increased significantly overnight.

One thing that is constant is that each code loop continues to focus on knowing what the soil is saying for each batch.

Old school septic installations used a 100 foot trench per bedroom to determine the size of the septic field. This means that a 4-bedroom house received a 400-foot trench without facing the soil. It can be clay or gravel.

Signs That It Is Time To Have Your Septic Tank Pumping Scheduled

The next generation of setups began using “perc” tests, a step up from no soil testing at all. Essentially, a performance test is a pit that is dug, filled with a water column, and then timed to see how long it takes for the water to fall and penetrate the soil. The problem was that perc tests were unreliable and often the results could not be reproduced.

And “smart” soil testers liked to find gopher burrows and run their infiltration tests there because the infiltration rate was so high!

Here we are. Current regulations require at least 2 soil tests to be completed as part of a certified septic system design. At least one should be a dug test pit, and the other may be a test well. But many designers make two test pits (if you have a backhoe or backhoe on site, you don’t need to take a truck out to sample the well).

Once inside the test pit, we look for a limiting layer, which can be any number of things. It can be a layer with very poor permeability (for example, heavy clay), poorly structured, bedrock, sandstone, etc. It can also be a layer such as gravel (which allows wastewater to pass through too quickly and therefore not be treated). Groundwater (soil water) is also considered a limiting layer.

Regulations require that a minimum vertical distance of the discharge point (such as the bottom of a trench) be maintained from any confining layer. This depends on the quality of the drains, but is usually 3 or 5 feet.

For example, if we have a trench that is 3 feet deep and we want a vertical distance of 5 feet, we need to have “good” soil (no confining layers) within 8 feet of the surface.

In the first image, you can see the different horizons (or layers) of soil as you move down from the surface. Each layer has different soil characteristics.

It is easy to see that the layer near the bottom of the test pit is very limited; It is not good to use water or tap water on this layer.

How Long Does It Take To Replace A Septic Tank?

The second picture is a little closer and shows that the boundary layer starts about 42 inches from the surface.

Because the confining layer is shallow, this area may not be suitable for deep tillage (trenching) because we cannot hold 3 feet or 5 feet vertically from the bottom of the trench. Most likely, the best option here will be a healing mound.

Have you ever been in a test pit or seen similar soil in your home? If you are building your own house and start digging a hole for a basement, take a quick look at the walls of the hole and you can see the layers!

[VIDEO:] A quick overview of how we dig our test pits. We try to break up as little space as possible. Test pits should be dug close to where the septic system will eventually be located. Holes are always closed before we leave. Soil tests are necessary to determine what type of septic system a home or business needs. A soil test will tell about the type of septic system, the size and location of the septic system. Before testing the soil, I discuss the owner’s needs. After the first meeting, soil pits or wells are dug into the ground. A soil tester can then climb into the hole and determine the characteristics of the soil. Some characteristics include texture, soil type, and high water table characteristics.

Soil characteristics determine which septic system is needed to treat domestic wastewater. When a septic system distributes domestic sewage or wastewater to the ground, it must be 3 feet above the limiting factor. If the underground system cannot obtain a 3-foot clearance, then a bank or embankment is installed. Stains, native species, structure and texture are limiting factors.

Spots or stains are soil colors caused by the presence of water in the soil. The number, size, contrast and color of the spots indicate how often and for how long the water is present. Bedrock is a limiting factor because it prevents runoff from spreading over land or allows it to seep into groundwater before it can be treated. The texture and structure determine how well the soil drains. If the soil is impermeable, you will create a septic tank in your yard. Loose soil does not allow enough time for cultivation.

A soil tester documents horizons, or different layers of soil. It records the consistency, the type of border between the horizons, the size and number of roots in the soil. A plot map is also created during the soil survey. The map shows where pits or wells are located in the area, the location of current or proposed structures, wells, the slope of the land to be studied, and the legal description of the site.

After conducting the soil test, the surveyor completes a Soil and Site Assessment Report. The report describes the characteristics of the soil and contains the information needed by the septic system installer to design the system and obtain the necessary permits. The report also includes a sitemap. The soil tester reports to the county or agency that regulates septic systems. Pressure split septic systems are often used when permeable soils are relatively shallow and a uniform distribution of wastewater is required for good treatment. Pressure-operated septic systems not only provide good sewage treatment, but sometimes drainage fields are not always suitable for placement near the house. During long journeys
