This operational wastewater treatment plant receives flows from the Windermere catchment and supports a £200 million upgrade programme aimed at reducing nutrient runoff and storm overflow frequency. It employs primary sedimentation, activated sludge, and sludge digestion, while serving as a testbed for innovative filtration and reed-bed solutions. The site demonstrates modern environmental engineering in a sensitive UNESCO lake setting.
Guided tours (~90 minutes) are available for groups of 4–10, typically offered Monday–Friday mornings. Participants receive PPE (vest, helmets, glasses), onsite parking, and a health-and-safety briefing. Tours include an overview presentation, viewing of treatment process units, and expert Q&A.

Battersea Power Station, once the world’s largest brick building, supplied mid‑20th‑century London with electricity. Its Art Deco interiors and four chimneys remain central to the 2022 redevelopment into a mixed‑use complex. Guided tours explore restored Control Rooms and turbine halls, offering a striking example of industrial heritage conservation.
