: How can I disconnect a trailer from the septic tank. Can I just saw off the plastic pipe and cap it?Rose, the short answer to your question is Yes, but you had better check with the local regulatory agency to find out what you have to do with the septic tank. If one abandons a septic tank in Colorado, it is required to have the contents pumped by a sewage pumper, and the tank must then be removed or filled with soil. JWA
