Do I Need an Alternative Septic System:

If your home site has thin soil over bedrock, a steep slope, or is on a high water table then the Alternative Septic System is a replacement for the conventional system.


"Septic System Alternative Designs" refers to any onsite wastewater disposal method other than the widely used conventional septic tank and leach field. In the U.S. most states require that an "alternative septic system" be designed by a professional and submitted to the local health department for approval. The alternative septic system designer conducts the site and soil inspection and testing, prepares the system design and installation plan, supervises the septic system construction, and certifies that the system was installed as designed.

Alternative septic system designs are used for new or replacement septic systems on difficult sites where soil conditions (such as a rocky site, limited soil percolation rate, or high ground water level), or other terrain conditions (such as limited space for a septic system or steeply sloped sites) do not permit the installation of a conventional septic tank and drain field system.

 

Alternative Septic Types & Management:alternative septic

In areas with very slow percolating soils and/or high water tables, wastewater may surface even on new absorption systems. In areas with soils that percolate too fast, in rocky terrain, or in areas with high water tables, the effluent from a septic tank can move through the soil with little soil treatment, thus polluting underground water supplies or surface waters. In all the above cases, the discharge from the Alternative System, when coupled with properly designed accessories, can prevent these type health hazards or pollution problems. Alternative septic systems are installed with

tanks that utilize only non-corrosive hardware. All hardware items are either PVC, Stainless Steel, Polyethylene or Neoprene. Corrosion is a major problem with buried tanks, particularly when they exist in a corrosive wastewater environment, so you can be sure to have a longevity in the life of your system with the following brands that
Dowdy's Well and Septic Service supports and recommends.

  • PURAFLOW
  • ADVANTEX
  • CLEARSTEAM

Single-Pass Sand Filters
Single-pass sand filters treat pathogens well, which is especially important when a system must be placed less than three feet above the water table or bedrock. Because sand filters have been in use for a long time, system design and reliability are well established. The materials needed to make a sand filter are readily available in Minnesota.

Recirculating Sand Filters
RSFs use similar principles as sand filters--with a few differences. The materials in an RSF are coarser (in comparison to a single-pass sand filter) and do not remove feces as effectively. A fine gravel is often used. They are also loaded at a much higher rate and are therefore smaller. RSFs remove a significant amount of nitrogen.

Peat Filters
Peat filters remove pathogens effectively and remove some nutrients as well. They are sometimes sold as manufactured containers, allowing for flexibility of design. Because the medium has an organic base, it breaks down over time and will need to be replaced every 10Ð15 years, which is significantly more often than a sand filter. A disadvantage of peat filters is that the ready-built containers must be placed above the ground surface to breathe, where landscaping may be required to disguise them.

Constructed Wetlands
Constructed wetlands use native plants to aid in treatment of wastewater. A wetland system is not as effective as a sand or peat filter, and requires a significantly larger area. It may not be as effective as some of the aerobic tanks. Performance varies seasonally and, in Minnesota, a wetland system performs much better in the summer than in the winter. Vegetation is a significant part of the treatment process and therefore must be maintained and managed.

Aerobic Treatment Units
Aerobic treatment units (ATUs) are single tanks that require less space than sand and peat filters or constructed wetlands. They can handle different strengths of wastewater with adjustments to air flows and configuration. However, all of the mechanical pieces need to be correctly maintained for proper treatment to occur. Studies done in Wisconsin have shown a large degree of variance in terms of ATU operation and maintenance that greatly affected how well they perform. Electrical costs are usually higher than those of the other systems.

Separation Technologies
Separation technologies and non-water toilets allow homeowners to reduce water use and install a smaller system. Reducing water use may provide a cost savings in itself. Taking toilet waste out of the system through a composting toilet removes about 70 percent of the nitrogen along with other nutrients. These systems may require extensive plumbing changes in an existing residence. A significant increase in management is needed to operate the unit and handle the solids from the composting tank.
