A complete cleaning of a container is achieved by the use of a removable polyethylene liner which removes all debris and avoids contact of the debris with the container at all times. Therefore cleanup of the container is quick, easy and simple. The liner is preformed to allow for a perfect lining of the entire container. The removable liner has the possibility of accommodating multiple openings for connection with one or more inlet pipes and one or more outlet pipes. The liner includes a series of prefabricated portions which may be weakened and removable to selectively accommodate multiple inlets and/or outlets. Only the desired position of a desired inlet or outlet is removed from the liner to accommodate a friction fit with an exterior surface of the inlet or outlet pipe to the container. Alternatively, a compressive force is exerted on the liner between a pipe and a coupling portion to hold the liner in place.

I claim: 1. In combination, a container and a removable liner, said combination comprising: an inlet and an outlet to the container, at least two openings in the liner, and a peripheral edge of one of said openings being removably secured to said inlet and a peripheral edge of the other of said openings being removably secured to said outlet, said at least two openings being smaller than said inlet and said outlet, the peripheral edges of said openings being removably secured to an exterior surface of said inlet and said outlet, the peripheral edges of said openings being stretched around and closely contacting the exterior surfaces of the inlet and the outlet. 2. The combination as claimed in claim 1, wherein the liner includes a plurality of designated potential openings into an interior of the liner. 3. The combination as claimed in claim 1, wherein the liner includes two layers. 4. The combination as claimed in claim 2, wherein the designated potential openings include one of lines of weakness, reduced thickness portions, perforations and projecting truncated cones. 5. The combination as claimed in claim 1, wherein the liner is made of polyethylene. 6. In combination, a container and a removable liner, said combination comprising: an inlet assembly for receipt of waste water into the container and an outlet assembly for removal of the waste water from the container, at least two openings in the liner to accommodate passage therethrough of at least part of the inlet assembly and the outlet assembly, a peripheral edge of one of said openings being removably secured to said inlet assembly and a peripheral edge of the other of said openings being removably secured to said outlet assembly, and the liner assuming a shape of an interior surface of the container and having sufficient openings to accommodate all inlets to and outlets from the container, said at least two openings being smaller than said inlet assembly and said outlet assembly, the peripheral edges of said openings being removably secured to an exterior surface of part of said inlet assembly and part of said outlet assembly, the peripheral edges of said openings being stretched around and closely contacting the exterior surfaces of the part of the inlet assembly and the part of the outlet assembly. 7. The combination as claimed in claim 6, wherein the peripheral edges of said openings being removably secured to an interior surface of another part of said inlet assembly and another part of said outlet assembly. 8. The combination as claimed in claim 7, wherein a coupling piece extends into the another part of the inlet assembly and the another part of the outlet assembly to removably secure the peripheral edges of said openings to the interior surface of said another part of the inlet assembly and said another part of the outlet assembly. 9. The combination as claimed in claim 6, wherein the liner includes a plurality of designated potential openings into an interior of the liner. 10. The combination as claimed in claim 6, wherein the liner includes two layers. 11. The combination as claimed in claim 8, wherein the coupling pieces include a tapered exterior surface for wedging against the interior surface of the inlet and the outlet to hold the peripheral edges of the openings against the interior surfaces of the inlet and the outlet. 12. The combination as claimed in claim 9, wherein the designated potential openings include one of lines of weakness, reduced thickness portions, perforations and projecting truncated covers. 13. The combination as claimed in claim 6, wherein the liner is made of polyethylene.
