Oh. Did you know why residential septic tanks were built that way? To 'purify' waste water by means of gravity pulling it down and strained through layers of different types of rocks and sands underneath and sometimes flows back into the sea/river through some natural (not man-made) 'sewers'.
Unless the people who design or construct the septic tanks in residences didn't know that or never cared to construct it properly that way, well...they're going to ask for sewage 'services' to seep it and the 'services' will throw it away on some open land in Doha...
