‘Southern Outfall’ is the name for the confluence of sewer lines from across south London—where things come together and continue on.
It is this cycle of energy, coalescing and redistributing within a system, that has engaged Mhairi Vari for the last three years as a volunteer and resident artist at Crossness while pursuing her PhD in music and sound arts through the University of Greenwich.
Mhairi explains, “The abstract and playful works that constitute SOUTHERN OUTFALL go in some way to explore and celebrate that huge collective effort—marking 40 years of voluntary activity here, in this the 160th year since the beam engines began operation.”
In SOUTHERN OUTFALL, Mhairi examines her relationship to Crossness through the overlapping lenses of the physical space and volunteer action essential to its continuing purpose. Her long-term dedication has allowed her to engage deeply with Crossness—not just as a historical institution, lost in time, but as a dynamic entity, continually redefined. Using video installations, sound design, and sculpture, incorporating visual cues like the volunteers' hi-vis orange workwear and drawing parallels with the flowing movements found in tai chi, Mhairi offers a fresh interpretation of Crossness, shaped by her personal experiences with the site.
SOUTHERN OUTFALL invites us to step into the microworld of enzymes oozing around our gut, before entering the macroworld of the sewer system. All this is brought into focus through generation upon generation of human activity which Mhairi unites amongst the pumps, ornate ironwork and rust of Crossness Pumping Station.
Crossness. What an incredible life! Born in crisis; built as a saviour to the health and well-being of Londoners, the pumping station was a place of beauty where art and industry fused. Then, after 80 years’ service, it was left to decay.
Mhairi’s practice leads us into a space reconfigured anew. In this melding of material, experience and place, we encounter Crossness again. Now, through the hands of volunteers, it stirs once more—not with the roar of industry, but with the persistent pulse of care. Their devotion rekindles its spirit, transfiguring its service into something living and sublime.
SOUTHERN OUTFALL is a sensitive exploration and celebration of all therein. Please join us in discovering the ‘Cathedral on the Marsh’, the SOUTHERN OUTFALL.
