Local septic work: pumping, installation, design, inspection, repair

Pumping. A pumper needs the lid location and tank capacity. Locating a buried lid without the recorded as-built is billed as labor.
Installation. A permit before work starts, an inspection while the system is open, and a final as-built submitted at completion, which is what ends up in the county file.
Design. Design flow from bedroom count, a soil and site evaluation, tank sizing and the required setbacks. On a lot with an existing permit, the original soil work is often already on file.
Inspection. Lenders and many counties require one at sale or transfer. Inspectors start from the recorded as-built; without it they are probing blind.
Repair. Starts from the existing as-built, since the current tank, field and any reserve area constrain what can be rebuilt.
