A sewage removal system 10 is provided for quickly, securely and sanitarily connecting the onboard holding tank H of a typical recreational vehicle or travel trailer to an in-ground stationary waste disposal site S. The system 10 includes two hoses 20, 21 which may be coupled via a union 50 to provide hoses 20, 21 of greater combined length to reach the site S when located too far for a single hose 20, 21. The hoses 20, 21 include quick connect couplings 30 secured to each end 22. Locking hooks 40 extend from the annular rims 39 of the couplings 30 to provide a means for securely engaging protrusions 56, 66 to create a sealed joint. The system 10 includes two elbow adapters 60 to allow simple connection to an inlet tube T of the stationary waste disposal site S. The first elbow adapter 60 includes a male threaded connector 70 for coupling with a female threaded fitting F of the inlet tube T. A second elbow adapter 60 includes a female threaded connector 80 for connection to a male threaded fitting M of the inlet tube T.

[ What is claimed is:] [1.] A system for secure delivery of sewage from a mobile holding tank to a stationary waste disposal site, the stationary waste disposal site presenting a threaded inlet tube for attachment to the sewage removal system and the holding tank presenting an outlet pipe with a cylindrical ring having tabs extending radially therefrom for attachment to the sewage removal system, the system comprising in combination:a hollow adapter having an upper end and a lower end;said lower end having a threaded surface configured to interface with the threaded inlet tube of the stationary waste disposal site, such that fluids passing through said hollow adapter can pass into said inlet tube;said upper end having a cylindrical collar with at least two knobs extending radially therefrom;a hose, said hose having a first end and a second end;said first end having a first coupling thereon with a tab and ring fastener capable of attaching and detaching with the tabs and the cylindrical ring of the outlet pipe, such that fluids passing out of the outlet pipe can pass into said hose; andsaid second end having a second coupling thereon with a knob and collar fastener capable of attaching and detaching with said knobs and said collar of said upper end of said hollow adapter, such that fluids passing through said hose can pass into said hollow adapter.
