The first step in any septic installation is to perform a site survey and do a percolation (soil) test on the area where the POWTS, Private Onsite Wastewater Treatment Systems is going to be installed.
The system then can be designed based on the findings of the survey and results of the soil test. After all this is the installation of septic tank system pipes. Below are some of the guidelines needed in installing a pipe lines for a septic tank system:
- Safety during sewer line or septic line excavation
- Recommended allowable slope for sewer or septic line piping
- Sewer or septic line trench specifications: uniformity, soil compaction, width
- Specifications for placing sewer or septic piping into the excavated trenches
- Recommended sewer line size (diameter) and slope
- Avoiding rocks, voids, using sand, protecting the new septic or sewer pipe from damage
Important: Guidelines and/or details may less differ if it is only replacement of pipes.
