Persons moving to a home that uses a septic tank may need some information about this onsite wastewater treatment system. Septic tanks are an efficient way to safely dispose of contaminated water from the home. If properly cared for, the septic tank is a vital key top protecting the environment. Tanks that are not properly taken care of can allow raw sewage to leak onto the top of the ground and into runoff water.
Proper care for a septic tank begins in the home. There are certain items that should not be flushed down drains. Grease, plastic and latex do not break down in the system and should be disposed of in another manner if at all possible. If these items are flushed down a drain or toilet, they tend to add to the scum layer at the top of the tank and cause the tank to need pumping sooner.
While many household cleaners are diluted to the point that they do not cause a problem, occupants of the home will want to avoid overuse of these materials with the tank. In addition, it is recommended that when choosing laundry detergents, persons with septic tanks choose liquid detergents rather than powders.
Septic tanks require regular pumping. Generally speaking, a tank serving a family of four needs to be pumped every three years. If the home has more family members, the tank will need servicing more often. In addition, if the family makes heavy use of a garbage disposal, it can cause the tank to require servicing more often. Pumping should occur before the scum level drops below the baffle or solid materials may leak into the drain field and cause failure of the field.
When homes have septic systems, care must be used to avoid driving over the tank or drain field. Driving over the tank could cause the lid to break and may drop a vehicle directly into the tank. Driving over the drain field can compress the rock and pipe that allow the system to distribute the treated wastewater into the soil.
While it is possible to find many additives for septic systems, most experts agree that there is no need to add these materials to the tank. There is enough bacterial in the materials that fill the tank that will cause a natural breakdown of the substances. Most septic tank additives only add more pollutants to the streams.
Most older septic systems used gravity to distribute the treated water into the drain field. Today, however, in order to place septic systems on property in places where a traditional gravity flow drain field does not operate correctly, many homes are being built with pump systems or sand filters. These systems must be engineered to allow for pollution free distribution of the treated water. They can be very expensive systems and require even more caution at taking care of the system.
