There are two basic parts of a septic system: the septic tank and the cesspool. The cesspool is the area that provides soil absorption. Waste flows out of you home through septic tank lines and enter near the top of the septic tank. In a properly functioning septic tank the organic solids float to the top of the tank and inorganic solids sink to the bottom. The bacteria in the tank should convert the organic solids to a liquid form. Sludge forms and settles to the bottom. This process allows the liquid to flow out of the septic tank and into the cesspool.
The main cause of failure in a septic system is the build up of solids in the tank You can see this presented in a diagram of a cross-section of a tank in our Cesspool 101 page on the CDM Cesspool Services website.

Some other helpful septic information sources

The United States Environmental Protection Agency (EPA) makes their free consumer guide, “A Homeowner’s Guide to Septic Systems” available online in a PDF format for easy download. They include some interesting tips for homeowners with waste disposals, washing machines, etc. And if you a hot tub do not connect it to your septic system. It is likely to overload the tank when the tub is drained causing the solids in the tank to be disrupted and clog the drains.

The Wikipedia is something many people turn to on the web to find out basic information including homes, home improvement, plumbing, landscaping and other topics related to septic systems. Their page on the septic tank defines septic as “the anaerobic bacterial environment that develops in the tank and which decomposes or mineralizes the waste discharged into the tank.”. Septic tanks vary in size but typically hold 1,000 to 1,500 gallons. This is the range common on Long Island. Recent designs often include two chambers with a manhole cover for each.

You will find some useful facts in a report on Long Island Groundwater from a Stony Brook University course on the geologic development of Long Island. There are about three million people in Nassau and Suffolk counties that are dependent on the groundwater ecology. Private septic tanks do have a significant impact on the freshwater quality on Long Island.
