The process of abandoning a septic tank and installing a new sewer lateral in Miami Dade county is simple. The homeowner must retain a civil engineer for design services. Typically the septic tank must be pumped out, cleaned and filled with sand then certified to the local health department.
The hard part is connecting to the county owned sewage collection system. Allocate a minimum of six months get the work completed and conveyed. MDWASD uses the e-builder tracking software. That software tracks all aspects including As-built acceptance.
In some cases the homeowner simply cannot connect to an existing sewer line due to utility conflicts and/or elevation differences.
The following pictures show utility conflicts during a new commercial sewer lateral installation. We resolved those conflicts because we had an additional 24″ of cover along the alignment.
