This is why septic tanks do not fill up quickly and need emptying after a few years. It is advisable to avoid pouring toxic waste down the drain because such waste can alter the pH of the system. Enzymes and bacteria flourish in non-,acidic, environments so if the pH level gets altered, the microorganisms might die.
