Septic Tank De-Commissioning

In preparation for the demolition of the existing house, the septic tank was pumped-out today. The tank was badly cracked, and would definitely have been leaking straight into the ground around (the walls were made from bricks, about 5 feet deep). Between now and the actual demolition, some ground-water may seep back in, but the bloke doing the pumping said he could easily come back and remove that on the day of the demolition. The time-consuming part of pumping the tank empty was getting the sludge out of the bottom, and washing it out with a hose.
