The soil is shallow in Ruiru area, approximately 1 foot deep hence making it hard for the septic tank soak pit to soak away the treated waste water from the house.
Solution for this is to dig the soak pit over 3 meters deep until the hard rock layer is broken to reveal a soft rock type that has the spongy ability to soak away the waste water into the underground water drainage channels that follow gravity.
