The type of septic system your site requires depends on its soil characteristics. A brief description of the three most commonly used systems can be found below. Top Tier can assist you with your entire septic system project from soil and site evaluation to system design to final installation.
Often called a conventional system. This is an ideal onsite treatment system where soils are deep, permeable and well-drained. The In-Ground Gravity soil absorption system is simple, inexpensive and relatively maintenance free. The In-Ground Pressurized system can be used where elevation is lacking by means of a pressurized pump system.
An At Grade system may be used in areas that are too shallow to accomodate an in-ground system. This system uses pressure distribution to apply effluent to the original soil surface
A Mound system is required for soils that have permeability and depth limitations too severe for an at-grade system. The mound system uses additional engineered sand in order to provide additional treatment media to provide enough separation above the soil limitation.
Property Transfer Septic Inspection
Top Tier also provides septic system inspections for property transfers. As part of the inspection we provide information regarding:
