• A soil evaluation is the key to deciding what on-site system, if any, can be built on a property. It is not a bad idea to have a soil scientist evaluate a piece of property before you purchase land if sewer is not available.
  
  
  
  
  
• An example of a plot plan with contour lines mapping out the topography.
  
  
  
  
  
• Staking out a site. Determining the elevation.
  
  
  
  
  
• A system must meet separation distances from wells, property lines, buildings, and water bodies.
  
  
  
  
  
• More measurements.
  
  
  
  
  
• Some systems are plowed before they are built. Others must go in on undisturbed soil.
  
  
  
  
  
• Sometimes you need a helping hand.
  
  
  
  
  
• Construction of on-site systems should occur when soil is in the semi-solid state.
  
  
  
  
  
• It is way too wet to be building an on-site system. Soil must be moist to dry to allow for proper infiltration of the wastewater. Building a system when the soil is wet will encourage rapid failure.
  
  
  
  
  
• Some systems use tilled beds instead of trenches.
