Commercial Drainage Goring On Thames ✪

But it cannot swallow our apathy. Next time you see a café owner hosing fryer oil toward a curb drain, or a builder washing cement into a roadside gully, remember: That drain leads to the Thames. And the Thames leads to all of us. If you are a commercial business owner along the Thames corridor and need a drainage audit, contact Thames Water’s Trade Effluent team or your local council’s environmental health office.
