Septic Tank Systems Sandy Oregon & Surrounding Areas

Look to Goodman Sanitation in Sandy, OR for complete Septic Tank Systems, installation, repair, and maintenance. We handle all of your septic wastewater concerns.

A septic tank systems is more than just what we all know of as the watertight septic tank that receives the wastewater from a home plumbing systems. It is followed by a drainfield (ie: leach bed) made up of a network of perforated pipes that distribute the treated water into the soil for final treatment.

Septic tanks work by containing bacteria that grow well in oxygen-poor environments. These bacteria convert most solids into liquids and gases as a portion of the treatment process. Bacteria that thrive on oxygen reside in the drainfield, or leach bed, and the treatment process begun in the septic tank is completed here. A septic tank that is working correctly generates wastewater that is relatively clear but may still contain some disease carrying organisms and will have an odor. For this reason, the liquid waste (effluent) should only flow into the drainfield for final filtration and never flow onto the ground surface or into the groundwater level.

Goodman Sanitation has knowledgeable and experienced technicians ready to make sure your septic tank systems is installed and maintained properly and is of the correct size to ensure years of trouble-free use treating your wastewater and protecting groundwater quality in areas without municipal sewer service being available.
