Sewage Treatment Questions

  • Are you building a new house?
  • Are you adding a bedroom to a house served by a septic system?
  • What is a percolation test anyway?
  • Why do I need a mound in my yard?
  • What alternatives are there?
  • Can I add onto my septic system in the future?
  • How do I size my septic system?
  • Where do I find the help I need to get an On-site Sewage Disposal System done?

Think about IT (at least for a moment). You flush the toilet and IT is gone, you open the washing machine and have clean clothes and IT is gone, you open the drain after a relaxing soak in the tub and away IT goes. Where does IT go anyway? If you live in an area without public sewer like some 80% of us do, IT goes into an on-site sewage disposal system, a.k.a. septic system.
digging septic systemMost people have their first direct experience with a septic system when they build a new house. It is at this point that the septic system must be designed and installed. All septic systems are sized based on the number of bedrooms – not the number of bathrooms. The number of bedrooms controls the number of occupants which in turn dictates the amount of water used. This is why if you are to add bedrooms to an existing house you may need to install a new septic system. Septic systems, unlike houses cannot typically be added onto.

In order to design a septic system, a percolation (perc) test must first be conducted. A perc test is actually made up of two parts. In the first part, a backhoe is used to dig holes into which a Sewage Enforcement Officer (SEO) descends. The SEO looks at the soil to determine if it is suitable for the placement of a septic system in that area. It is also at this time that the type of septic system is determined, i.e. regular, mound, etc.

The second part of the process is the digging of six holes by hand. Water is poured into these holes over a two day period to see how fast it is absorbed. This part of the test determines how large of a system is required. Current regulations require suitable soils to be between the bottom of the septic system and a limiting factor in the soil. When there is not enough good soil, sand is used to make up the difference. This is why some people have to install a mound system. They did not have enough good soils so they needed to add sand, creating the mound. There are numerous alternatives systems which allow almost any parcel of land to have a septic system. These systems become more expensive as they increase in complexity, but without them, the lot will be useless as a building lot.
If you are still thinking about IT, remember this: A septic system should be considered a living being and treated as such. If you treat it with respect, you will find that you do not need to think about where IT goes . . . as often!
