About this programme
22/22. Bill Massa, president and CEO of America's largest waste-water treatment company, embarks on a secret mission to examine the frontlines of the service he runs. He is initially impressed by the firm's pelletising machines - which transform sludge into fertiliser - but is disappointed by the lack of recycling bins at the plant. The experience takes an even grubbier turn when he is challenged to clear out a holding tank that has not been cleaned for 27 years.
