ABSTRACT:
A method for cleaning a septic tank provided with at least two successive fermentation and decantation compartments connected to each other by a lateral opening. According to this method, the light and/or heavy sludges contained in each compartment are pumped and discharged in a waste tank whereas the bacteriological liquid medium of both compartments is pumped out and stored in a storage tank. The liquid medium kept in the storage tank is reintroduced into the septic tank after the same has been cleaned, to reactivate said tank thereby making it immediately operative. A tanker especially designed for carrying out this method is also disclosed.
