A wastewater filtering system is provided for the passage of the wastewater from the home to the septic tanks prior to passage to the drain fields. The system comprises a separate septic tank assembly and a grease trap assembly operatively adapted to receive the wastewater from the home prior to the passage of the wastewater into the drain fields. Septic tank assembly and grease trap assembly are specifically configured to separate the filtering of waste water from the kitchen from the sewage from the bathrooms to prevent the clogging of the entire filtering system.
