Commercial Drainage Goring On Thames [new] [2026]

When these fatbergs block the pipes, the raw sewage doesn't back up into the street—it goes into the river. London’s combined sewer overflows (CSOs) are designed to eject stormwater mixed with sewage into the Thames when the system gets too full. Thanks to commercial grease clogging the arteries, those CSOs are triggering even during light rain. There is a new villain on the banks of the Thames: tile adhesive and concrete washout .

The real fix is happening on the surface. In Richmond and Kingston, new bylaws require commercial kitchens to install (Grease Recovery Units) that are emptied weekly. In Reading, construction sites now require pH-neutralization tanks before any water hits the drain. The Future As climate change brings more "1-in-100-year" storms every other autumn, the commercial drainage of the Thames basin will be tested like never before. The river is a forgiving beast—it has swallowed Roman sewage, Victorian industrial waste, and the Blitz. commercial drainage goring on thames

"People think flushing a wipe is harmless," says Sandra Kolve, a drainage engineer with 20 years on the river. "But commercial drainage isn't designed for volume. It’s designed for speed. When a restaurant closes at 11 PM and pours 50 liters of hot oil down the sink, it hits the cold brick sewer and solidifies instantly." There is a new villain on the banks

But beneath the waterline, a crisis is bubbling up through the manholes. It is not just rising sea levels or Atlantic storms that keep Thames Water’s emergency planners awake at night. It is —the grease, the concrete, and the "wet wipes" flowing out of London’s kitchens, car washes, and construction sites.

On the surface, the River Thames is the picture of serene commerce. Tourist barges putter past riverside cafés in Oxford, property developers crane over luxury flats in Putney, and freight moves silently through the Lock gates at Teddington.

Last spring, the Environment Agency fined a major developer £200,000 after a "milky white discharge" was spotted flowing from a drainage pipe near Wandsworth Park. The culprit? A wheel wash station draining directly into a surface water sewer.
