Before world leaders gathered in Halifax for June’s G-7 summit, organizers fretted over an embarrassing problem: one of the city’s sewage pipes emptied just outside the meeting site, spewing raw sewage into the otherwise scenic harbour. Worried that foreign dignitaries and journalists would smell sewage and spot floating condoms, tampon applicators and toilet paper, politicians devised a plan. Their proposal? To extend a submerged pipe into the harbour, improving the view and sparing the visitors’ noses. The federal government ended up scrapping the plan, but not because merely hiding the sewage wouldn’t solve the problem. On the contrary, it simply deemed the $1 million project too expensive.
