1. A thermo insulated sewer water treatment environment comprising: ground having a top surface,a sewer water treatment system located in the ground below the top surface of the ground,at least one thermal insulation blanket located on the top surface of the ground above the sewer water treatment system operable to inhibit freezing of the sewer water treatment system,said blanket comprising,first and second sheet members,a core of thermal insulation material located between said first and second sheet members,each of said first and second sheet members and core having outer peripheral side and end portions,at least one U-shaped member located around the side and end portions of the first and second sheet members and core,fasteners securing the U-shaped member to the first and second sheet member and core,a plurality of grommets secured to and extended through the U-shaped member, first and second sheet members and core, andstakes extended into the ground to retain the blanket on the top surface of the ground above the sewer water treatment system,said stakes comprising first members extended into the ground adjacent the blanket, and downward extended hooks secured to the first members engageable with the top of the U-shaped member, said hooks having portions extended through the grommets to retain the blanket on the ground above the sewer water treatment system. 2. The sewer water treatment environment of claim 1 wherein: the ground includes a water drain field and said sewer water treatment system includes at least one water tile located in the drain field, said blanket being located on the top surface of the ground above the water tile to inhibit freezing of the water in the tile and ground around the tile. 3. The sewer water treatment environment of claim 1 wherein: the ground includes a water drain field and said sewer water treatment system includes a septic tank and at least one tubular member located in the ground below the top surface thereof, said tubular member being coupled to the septic tank for carrying water from the septic tank to the water drain field, said blanket being located on the top surface of the ground above the septic tank and tubular member to inhibit freezing of water in the septic tank and tubular member and ground around the tubular member. 4. The sewer water treatment environment of claim 1 wherein: the fasteners comprisestitches securing the U-shaped member to the first and second sheet members and core, and said grommets extending through said U-shaped member, first and second sheets and core outwardly of said stitches. 5. The sewer water treatment environment of claim 4 wherein: the core of thermal insulation material is a sheet of foam plastic. 6. The sewer water treatment environment of claim 4 wherein: the core of thermal insulation material is a body of enclosed air cells. 7. The sewer water treatment environment of claim 1 wherein: the first and second sheet members are plastic fiber containing sheet members. 8. The sewer water treatment environment of claim 1 wherein: said stakes have shanks extendable in the ground and said hooks extended into the grommets adapted to apply lateral forces to the blanket and hold the blanket on the top surface of the ground above the water treatment system. 9. The sewer water treatment environment of claim 1 wherein: the U-shaped sheet member is a polyester fiber sheet member. 10. The sewer water treatment environment of claim 1 wherein: the first and second sheet members are polyester fiber sheet members and the U-shaped sheet member is a polyester fiber sheet member. 11. A method of inhibiting freezing of a septic sewage treatment system including a septic tank and at least one tubular member connected to the septic tank to receive liquid from the septic tank located in a drain field ground below the top surface of the drain field ground characterized by providing a thermal insulation blanket having an outer peripheral border and grommets secured to and extended through the border,covering the top surface of the drain field ground above the tubular member with said thermal insulation blanket having the outer peripheral border and a plurality of grommets, andsecuring the blanket to the drain field ground above the tubular member with fasteners having first members extended into the drain field ground and second members secured to the first members engageable with the top of the border and the grommets to retain the blanket on the top surface of the drain field ground. 12. The method of claim 11 including: extending a portion of the second members of the fasteners through the grommets to retain the blanket on the drain field ground over the tubular member to inhibit freezing of the liquid in the tubular member. 13. The method of claim 11 including: covering the top surface of the ground above the septic tank with a thermal insulation blanket having a peripheral border with grommets secured to the border, andsecuring the thermal insulation blanket to the ground above the septic tank with fasteners having first members extended into the ground around the septic tank and second members secured to the first members engageable with the top of the border and grommets to retain the blanket on the top surface of the ground over the septic tank. 14. The method of claim 13 including: extending a portion of the second members through the grommets to retain the blanket on the ground over the septic tank to inhibit freezing of the liquid in the septic tank.
