Power stations are somewhat of a delicacy when it comes to exploring, if you get the timing right the rewards that can be claimed from each untapped giant are endless. Lots Road was one such power station, sitting proud on the edge of the Chelsea Creek it had never before been accessed, a variety of cameras, high walls, razor wire and active security patrols thwarting all efforts from above. But what about below.

At this point we had only just started scratching the surface of the London sewer system, so potentially using them as a means of access was, to us, unheard of. A nearby storm relief ran directly under our targeted Lots Road, terminating at the pumping station next door. It couldn’t hurt to look.

Constructed in 1932, Eden is officially known as the “Walham Green storm overflow”, running from Walham Green to Lots Road Pumping Station in Chelsea. It serves both the main line Northern Low Level Sewer No*1 and the Fulham Branch. Roughly 10ft in diameter and reinforced with concrete, there is little to see excluding its two weirs with the LLS*1, but we were here for another reason.

To cut a long story short, although the storm relief may have given access to the Lots Road compound, thanks to the tidal range of the Thames, Eden always remains 10% flooded, the only way to progress would be with scuba equipment. No matter, we still had more options.
