Plastic Septic Tank Installation Cost
Construction ITEM DESCRIPTION
Construction unit cost for installation of a plastic septic tank.
Labor and Equipment Costs
We figure about 4 1/2 hours of backhoe time (with operator) to dig the hole, install the tank and backfill.
We also include 1 1/2 hours of unskilled labor to connect drain lines and do finish grading.
One plastic septic tank, 30 feet of 4" drain line, a few drain line connectors.
Source of Construction Pricing
Based on a few installations done by Turtle Creek Construction.
This cost covers average suburban or rural conditions, with fairly easy access, no tree roots or buried utilities. Add additional labor if there are complications.
Note that plastic tanks can "float" to the surface in wet soils. Be sure to fill the tank with water soon after installation!
