The original drainfield design included a grease trap, a septic tank, aerated treatment tanks, and a drip dispersal drainfield in sequential order. One of the primary reasons for the drainfield failure was that grease coming from the truck stop restaurants was not cooled before entering the septic system. Hot grease can pass through septic tanks without maintaining the necessary residence time. Once the grease built up in the drainfield, the drip emitters began to plug, resulting in a failed system.
