Is there an alternative to septic tank?
Is there an alternative to septic tank?
Mound systems work well as alternatives to septic tanks when the soil around your home or building is too dense or too shallow or when the water table is too high. Although they are more expensive and require more maintenance than conventional systems, mound systems are a common alternative.
What are the 2 types of septic systems?
Septic System Types. There are two basic septic system types — conventional and alternative. Site and soil conditions generally determine the type of system that should be installed.
What is an ATU septic system?
Aerobic Treatment Units (ATUs) are similar to standard septic systems in that they use natural processes to treat wastewater. But unlike conventional systems, ATUs also use oxygen to break down organic matter, much the same as municipal wastewater treatment systems, but in a scaled-down version.
What is a hybrid septic system?
A Hybrid STEP System is a sewerage collection system that uses a septic tank to contain and treat solids, a pump station to remove the clear effluent and a drain field to act as a backup to the pump station for disposal of the effluent during power outages.
What is the difference between an ATU and septic system?
How does alternative septic work?
This system uses a standard septic tank, but instead of the conventional pipe leach field, the leach field is made of interlocking polyethylene arches that provide a continuous drainage area. The chambers create an empty space for effluent to flow through, so there’s no need for gravel or geotextile.
What is a saprolite septic system?
If you have been turned down for a septic system approval due to shallow or expansive clay soils, you may have the option of installing a saprolite system. Saprolite is a chemically weathered rock. Saprolites form in the lower zones of soil profiles and represent deep weathering of the bedrock surface.
What is an alternative septic system design?
“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.
What is a conventional septic system?
Conventional System A decentralized wastewater treatment system consisting of a septic tank and a trench or bed subsurface wastewater infiltration system (drainfield). A conventional septic system is typically installed at a single-family home or small business.
How is septic effluent distributed to the soil?
Septic effluent is distributed to the soil by a drip system that flows by gravity from through a series of perforated pipes or porous piping material. Note that effluent may enter the drip system from a pump and pumping chamber however. DISINFECTION SYSTEMS, SEPTIC EFFLUENT for septic system designs.
What factors determine Sept septic system design and size?
Septic system design and size can vary widely, from within your neighborhood to across the country, due to a combination of factors. These factors include household size, soil type, site slope, lot size, proximity to sensitive water bodies, weather conditions, or even local regulations.
