Septic Tank Design Damascus Oregon & Surrounding Areas
Goodman Sanitation in Portland, OR knows the correct design of a septic tank systems is all-important for proper wastewater treatment and to protect groundwater quality. A septic 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.
Different soil types require different septic tank systems designs to function efficiently. Where soil is made up of clay or bedrock with a shallow water table, the septic systems needs to be elevated about the surface. This is called a "mounded" systems and ensures there is enough unsaturated, permeable soil providing adequate filtration for the wastewater before it ultimately reaches the groundwater table.
In other areas like flood zones located close to rivers and other bodies of water with already saturated soil, a more advanced wastewater treatment systems may be required to sufficiently treat the wastewater. These systems add oxygen or "aerate" the wastewater. In addition, there are also advanced wastewater treatment systems that help neutralize disease germs prior to their reaching groundwater levels by using peat moss-based or chlorinating chambers.
Septic tanks come in a variety of different sizes. Goodman Sanitation will determine the correct size for your home depending on how much wastewater is being generated. Factors that determine wastewater usage are how many individuals live in the home, how often a washing machine is used, whether there is a garbage disposal in use, and what materials are being introduced into the wastewater. We also provide education on water conservation and what wastewater practices will keep your septic systems healthy.
Note: More frequent pumping needed if garbage disposal is used
