The sewage system here is nature-based outside your house, not piped out to a centralized utility. Nearly all houses in Thailand (mine is in a village) have a septic tank outside the house, and the decomposition of human wastes and other things is dependent upon the natural bacteria thriving in that tank. The issue I\’ve seen is that the workers that install the system are not upto western style venting of sewer gases. They don\’t install P traps or vent pipes as we do in the west. My installer has been called out many times to get the sewer gases vented properly to get rid of the smell that stagnant water has when left in the pipes.
As you can see the installer placed the vent tube outside about 8 feet from the house. This may or may not vent out the gases from the gray water pipes as intended. We shall see. As far as black water gases so far so good but still the vent pipe is sticking up in the yard. Eye soar….
