Description & HistoryFirst explored by Pom and KM_Punk and with some help from CaveClan Member Keve who couldn't make the actual explore but helped with the leg work all over Peterborough.
Dumm & Dumm-err-er are 2 RCP drains with part brick chambers in Peterborough, built around 1969/1970 based on the markings on the rcp.
Relatively boring in construction..
Dumm starts out as a 6.5ft RCP but quickly changes to 5ft5 RCP for a few chambers before turning into a 4ft.
Dumm-err-er starts out immediately as a stoop.
PhotosDumm is the right hand side outfall, Dumm-err-er is the left hand side outfall
