Yours is a soak pit or a pit?If it a soak pit has it been partitioned to hold toilet flush water and "other" water separately?
it's a soak pit deep minus the rocks, I have the kawaida septic which drains in to this 'soak pit' it's just like those village wells but go as deep depending on number of houses and seal properly you wont have issues with overflow.
the problem with black cotton soil is if it rains heavily water seeps into your pit, the deep pit solves the issue by providing more dry surface area for water to seep in.
