How do I properly abandon my septic system?
Notify the Health Department within 72 hours prior to any excavation or construction. Then the septic tank must be pumped and removed or crushed in place and void filled or completely filled with earth sand or gravel.
When connecting to the sanitary sewer the building sewer must bypass the septic tank and slope at ¼ inch per foot to the municipal or district sewer main. A clean out within two feet of the foundation is generally required by the building code.
