A worker attaches the large, flexible discharge hose from the septic pump truck to a designated discharge point. While facilities may offer specific nozzles, it's common for waste to be discharged directly into a ground-level opening. The worker then opens a valve to release the accumulated septic waste from the truck, which flows out as a thick, dark material. The speaker highlights a past incident where a 'new guy' was hit with sewage after standing in front of the valve, emphasizing the importance of proper procedure.
