In the 1884 Street Cleaning report are listed the following five dumps: Canton, Spring Garden, Back Basin, Eager St. and South Baltimore. By the 1920s, Baltimore was burning its garbage at two incinerators. One at Sisson and 28th street. The other on Philadelphia road. What does this have to do with sewage? Both places are on streams. Sisson street on Jones Falls, which still has a household hazardous waste collection site (original building appears to be gone). And Philadelphia road, as seen in the one photo below dumped right into Herring Run, which empties into Back River then on to the Chesapeake Bay. These photographs come from glass plate negatives that were broken due to improper storage. If you have GPNs, handle them with care.
The horse drawn cart was replaced by the modern dump truck. Here they are backing into the Sisson Street Incinerator, also known as #1 incinerator.
Instead of just piling the refuse into a dump, hoping somehow it would disappear, the garbage was sorted and then burned. #2 Incinerator on Pulaski Highway.
