Here's a little information to educate the knowledgeable homeowner on the basics of onsite wastewater systems (septic systems). As you have questions or if you would like further information, please call us to speak with an engineer about your questions or concerns.
A septic system is an onsite wastewater treatment system that is used to treat and disperse of the sewage generated on the site.
In essence the typical process of a septic system is as follows: All of the sewage from the building flows into a septic tank. Some treatment occurs within the septic tank then the cleaner water (refereed to as effluent) flows to a leach field. The effluent then disperses into the ground where final treatment and entrance back into the environment occurs.
Every septic system is unique. A septic system is based upon site specific conditions, information, and site uses. A septic system-or Onsite Wastewater Treatment System-consists of a septic tank and disposal field. The specifics of each component must be specified for the site specific conditions.
Proper use and maintenance are an important part of a septic system's longevity. Some typical maintenance tasks include: pumping the septic tank, respond to apparent surface conditions, and maintain components as specified by the engineer.
The septic tank provides time for primary treatment to occur. A typical residential septic tank is about 1500 gallons divided into two compartment. The solids are settled to the bottom and fats/oils/grease float on the surface. The middle layer provides a relatively clear zone that flows through the baffle into the second compartment. The effluent flows from the second compartment out to the leach field.
All leach fields are different, but the purpose of all leach fields is to distribute the effluent to allow dispersal into the soil. Leach fields distribute the effluent into the soil where the soil treats the effluent and allows for water to enter back into the environment.
Leach fields are sized based on the soil absorption characteristics, topography, and other site specific conditions. Call us today (925) 447-5200 to discuss the specifics of your site and speak with an engineer to discuss a plan of action for your onsite wastewater needs. We don't want you to waste your money and we will give you options for the most appropriate long term solution for the site's wastewater needs.
Notice the septic system is below ground. You should not have any smell from a septic system. If there is smell, something is not right and should be evaluated. Give us call to discuss 925-447-5200
The septic tank is one component of the septic system. The tank's purpose is to provide time for the constituents of the sewage to settle. The effluent (pretreated sewage) then exits the septic tank to a leach field.
A leach field is the system that disperses effluent into the ground. All leach fields are slightly different and each leach field is specific to the project site.
Even the best septic system needs to be maintained. Please call Acorn Onsite, Inc. to speak to an engineer about proper care. Our staff can be reached at 925-447-5200
Septic Tank Pumping:
The usage and sizing of the septic tank will dictate the pumping interval. Generally a residential septic tank should be pumped about every 3 to 5 years.
To Have Optimal Performance Follow These Guidelines:
If installed, outlet filters should be cleaned annually, simply hose off the built up solids. If an outlet filter is not installed please ask about the benefits the next time the tank is pumped. If the filter has been damaged or questions arise please call Acorn Onsite, Inc at 925-447-5200.
