Questions about Septic Systems:
An Overview
Your septic system, when compared to urban and suburban living areas, functions as a mini sewer system, and as a mini waste treatment plant. All household waste is disposed to the septic system.The termination point of your septic system is the environment. What you put into your septic system and how you choose to maintain it are important.

Your septic system is buried in the ground and consists of some piping, a watertight tank and a leaching field.  It organically decomposes waste matter through bacterial action. The bacteria required to do the work enter the tank with normal household waste.

The leaching field consists of a network of perforated pipes laid just under the surface of the ground in a pattern on a bed of gravel. In a healthy system, 
clear water exits the septic tank and enters the perforated pipe network of the leaching field. It drains into the gravel, It is absorbed by the surrounding soil and evaporates up into the air above the field. If anything other than clear water exits your septic tank into the leaching field piping, both the leaching field and the environmeffer.
Some of the early warning signs that your system my have a problem. 
Bubbling in the toilet, Smells of sewage in your yard. Sewage seeping on top of the ground. Backing up in the shower.
Things that can make the title 5 less expensive are digging the inlet,outlet, and center cover  and the D-box up before the inspector comes. Having any and all paper work about the installation of the Septic Tank Leach Field Area available. Blue Prints, Construction Permits, previous paper work from former owners.

Things you need to do for the towns - Call the Board of Health and have them be there on that day to witness the title 5's. Have a check ready for them. Each town differs. Some towns do not require a board of health member. Please call them to be sure. 
First, let's compare a healthy septic tank and a septic tank which is unhealthy. A septic tank is a watertight box. When household waste enters this box, organic material floats to the surface where bacteria biologically convert it to liquid. We will call this the floating layer. Inorganic material and by-products of bacterial digestion do not float. They sink to the bottom of the tank and accumulate, creating a sludge layer. Water entering
the tank occupies the space between the floating layer and the sludge layer. A large clear  water layer is important in a healthy septic tank.Trouble begins when material from either the floating layer or the sludge layer exits the septic tank to the leaching field. This will clog the field's piping system and bring harmful unprocessed waste in contact with ground soils and ground water. A properly designed and maintained septic system is environmentally friendly and requires no major economic expense over the course of a lifetime.
