• A septic system is a suitable alternative for those who can't install a conventional waste removal system.Toilet bowl and bidet in a toilet image by terex from Fotolia.com
  
  

Recommended Septic Sizes

• Most communities recommend a 1,000 gallon tank for a house with up to three bedrooms. After three bedrooms, another 250 gallons in size should be added. A garbage disposal in the kitchen sink counts as one extra bedroom.
  
  

Maintain Your Septic System

• Regular maintenance of your septic system will help it stay clear, regardless of the size. Don't pour grease or oil down your drain. Do not add materials to your system like feminine hygiene products. Restrict the use of your garbage disposal. Having solids pumped out of your tank will also help keep it clear.
  
  

Bottom Line

• According the North Carolina State University Extension Service, "The septic system is an efficient, inexpensive and convenient method for treating and disposing of household wastewater. Because not all soils are suited for conventional systems, a comprehensive soil and site investigation must be performed before you purchase any land. Septic systems will adequately absorb and purify wastewater if they are properly maintained."
