Background
Septic systems are the principal means of wastewater disposal for most homeowners in rural areas. About 25 percent of homes in the United States use septic systems, with safe and reliable disposal of more than 4 billion gallons of wastewater per day. This is very mature technology which when properly installed and maintained will work efficiently for generations.
A septic system is a self - contained, underground wastewater treatment system that treats and disposes of household wastewater onsite. In rural areas, where lots are larger and houses are spaced widely apart, they are more efficient and less of value than centralized systems which have need greater density to substantiate their substantial costs. Septic systems are often classified as conventional ( the majority ) or alternative.
Conventional Systems
A septic system consists of two main parts a septic tank and a drainfield. The septic tank is a watertight box, regularly made of concrete or fiberglass, with an inlet and outlet channel. Wastewater flows from the home to the septic receptacle through a sewer tube. In the septic tank the wastewater naturally separates into solids and liquids. The wastewater forms three layers inside the cistern. Solids lighter than water ( same as greases and oils ) float to the top; solids likewise than water settle at the bottom. Partially clarified wastewater is homeless in the middle.
Naturally occurring bacteria gash down the solids. The waste that cannot be afflicted down settles in the bottom of the cistern and is periodically pumped out. The clarified liquid flows from the vehicle to the drainfield where it ' s uniformly distributed for final scrubbing.
A standard drainfield ( also known as a drain field or disposal field ) is a series of trenches or a bed lined with gravel or course sand, buried a few feet below the ground ' s surface. Perforated pipes run through the trenches distributing the effluent, which slowly trickles from the pipes out into the gravel and down through the soil. The gravel and soil are remarkably effective natural biological filters that purify the effluent within just a bound or two of travel.
Alternative Systems
Any onsite household wastewater treatment system other than a conventional tank and bleed field described leading is considered an alternative system. Alternative systems are typically used where the soils are rocky or solid clay and do not leach or perc, which refers to the capacity of the soil to permit water to flow through it and get pure. Alternate systems are also used where the terrain is steep or limited space won ' t permit a conventional receptacle and drainfield.
There are many types of alternative systems in use, reflecting the wide variety of site conditions. The Arizona Department of Environmental Quality has approved 20 different alternative system technologies. These systems typically rely on the deal of the septic tank to partially treat the waste water and implement an alternate rut for dispersing the effluent. Since the effluent can ' t filter through the existing native soil, these systems may rely on raised beds or mounds of engineered material considerable the natural soil to partially or fully treat septic effluent. Also widely used are evaporation - transpiration systems, which rely on the upward movement of moisture through imported engineered material, surface gain, and fundamentally into the air. There are even hi - tech microwave systems for uttermost locations ( solid rock and steep slopes ) where a septic container is just not feasible.
Because these systems are electrically and mechanically more knotty than the relatively simple conventional systems, they are typically more valuable.
Conventional or Alternate System?
Unless money ' s no subject, you ' ll want to know the answer to this matter before you irrevocably leave to buy your property. Why, through an alternate system can cost as much as $10, 000 to $20, 000 more than a conventional system to serve the duplicate challenge. This doesn ' t have to be a deal breaker, especially if you in an area where only alternate systems work. If so your costs will be twin to other ' s residences, and that ' s neatly the price of chamber to the whereabouts you ' ve chosen, which is often the case in mungo or steep regions. Nonetheless you should know this beforehand so you can budget wherefore.
Perc Tests
A percolation ( perc ) test determines the ability of soil to imbibe liquid and in consequence the tender-hearted of septic system the property will wish. A perc examination, typically conducted by technicians first by the normal health department, consists of digging a setup of holes in the domicile of the future drainfield, soaking the holes with water, and then measuring the time it takes for the water pop up to drop one inch. The results of the check are voiced in gazette per inch ( mpi ); better ( faster ) wearing soils arrangement in lower mpi values and in consequence smaller filter fields. A very high mpi value may manifest the need to establish an alternative system.
Ask your seller if a perc examination has been performed and if the results gratify the standards for a conventional system. If so, you may want to set out this information with the domain health authorities who deal with septic systems. They ' re likely to be close with the area and can confirm if other residences in the area rely on conventional or alternate systems. However, don ' t be surprised if the seller / developer has not done a lot specific perc examination. The seller may determine the apt system is self evident; especially in an area where all the residences are served by conventional or alternate systems. In homologous a case the seller has no motivation to pay for a perc evaluation. If the property is in an approved chip, some counties and municipalities hurting for the developer to conduct a certain number of perc tests and site investigations throughout the element, friar to offering lots for sale.
To adequately budget for this rate, you may want to speak to licensed contractors who have installed septic systems in the area. The state Registrar of Contractors or territory officials can supply the names of local licensed septic system contractors. An experienced contractor will typically have informed opinions about the site and useful type of system, and will repeatedly share those with booked clients. Ask about the estimated cost to inaugurate a septic system to serve your instinctive needs.
Combine what you ' ve learned from your research with the intelligence of well regarded local contractors and you ' ve got a handle on the type and cost of a septic system for your rural get away.
Conclusion
Septic systems are widely used in rural areas throughout the world. Exclude for exotic applications, septic systems rely on simple, natural processes and work reliably, efficiently, and without any meaningful operating cost to the homeowner. Virtually every where has a septic system solution, and most are simple and tender dogged.
Now you know enough to confidently resolve your septic system anxieties and get back to deciding about buying that rural property.
