Our concrete septic tanks are manufactured to meet local and state specifications. The State
of Nebraska requires that a licensed contractor install all septic systems. Precast Products works with your installer to deliver the products to your job site. We also offer free literature
on the proper care and maintenance of your septic system.
Major factors on proper installation are:
  • 1/8 inch per foot drop on line from house to tank.
• The top of septic tank should be 6 to 16 inches below grade.
   It is not guaranteed if below 3 feet.
• Distribution box should be installed when more than one lateral field is necessary.
