• a containment sump surrounding said septic tank for containing leakage of the contents of said septic tank, said containment sump having a larger volume than said septic tank;
• a device mounted adjacent a bottom of said containment sump for detecting the presence of fluid in said containment sump;
• an alarm device coupled to said detecting device for signaling the presence of fluid in said containment sump;
• a temperature measuring device external of said tank for monitoring an air temperature in the vicinity of said septic tank;
• a heating device, external of said tank, coupled to said temperature measuring device for heating said enclosed area of said building structure when said temperature falls below a predetermined temperature;
• a collection basin for receiving sewage from a plumbing waste pipe, said collection basin being arranged at a different location within said building structure and at an elevation which is below an elevation of said septic tank;
• a surge tank positioned above said septic tank, said surge tank having an outlet connected to said inlet of said septic tank;
