A manhole is a facility that is used to allow access to water lines. There are two primary types of manholes: standard manholes and drop manholes. A standard manhole is an opening in a sewer allowing access operators or equipment. It may also be called an access hole or maintenance hole. Drop manholes have a line entering the manhole at a higher elevation than the main flow line or channel (hence the \u201cdrop\u201d). Drop manholes themselves come in two varieties: inside drop and outside drop. Inside drop manholes route the higher-elevation flow down through the manhole barrel. Outside drop manholes route the flow to the main manhole channel outside of the manhole.<\/SPAN><\/SPAN><\/P>
