So next day, after waking with a dodgy tummy, we went on the search for the source of the stink. The house and shed tanks were closed up like Fort Knox so it had to be the header tanks. Up the hill at the back of the house with stilsons, screwdriver, ladder and net. First tank was fine. The second tank had obviously suffered from a fallen branch and there was a hole in the top. Not huge, but big enough. The smell could certainly escape.
Matthew gingerly unscrewed the lid and holding his breath peered inside. .....
We had the trifecta. Two dead possums in advanced state of decay with accompanying maggots. Mathew managed to net out 95% of one possum. We isolated the tank and unscrewed the stop cock. We would ask our friendly neighbourhood septic pumper to see if he could get rid of the rest.
Next smelly job was in closer quarters. Matthew crawled into the small cavity beneath the house to access the grey water pipes. Luckily there were some access points, but Matthew had to crawl on his tummy to get to them. Then with careful manoeuvring he managed to blast water using a high pressure cleaner minus the gun down the pipe. He did about four metres before he retired soggy to blast again another day, probably tomorrow. So our water still whiffs and we are boiling it and the drain is still partially blocked but there is always tomorrow and the septic cleaning guy.
