As planned, our new septic and pump chamber tanks were delivered and installed today. Offloading and placement of the tanks took less than 30 minutes, a testament to the careful preparation work. Since septic systems are based on gravity flow, any discrepancies in elevation will result in compromised function and must be corrected at this stage. Happily, the tank heights were perfect and the remainder of the day was spent connecting the tanks and beginning the backfill work.
