In the March 2001 edition of the Harvard Business Review, Paul Levy describes the management lessons learnt from the operations of a sewage treatment plant at Nut Island close to Boston, US, where a very dedicated and professional team was involved with running it across thirty years. “They were every manager’s dream team. They performed difficult, dirty, dangerous work without complaint, they put in thousands of hours of unpaid overtime, and they even dipped into their own pockets to buy spare parts.... (And) yet, in one six-month period in 1982, in the ordinary course of business, they released 3.7 billion gallons of raw sewage into the harbour. Other routine procedures they performed to keep the harbour clean, such as dumping massive amounts of chlorine into otherwise untreated sewage, actually worsened the harbour’s already dreadful water quality”.
