Can you moonlight as a sewer cleaner? In Marrakech, yes. Well, you can if you are familiar with the labyrinthine sewer system and know where to enter and exit those pipes. Sewer fixers keep the city clean by clearing the subterranean canals of blockages and obstructions, some of which, frankly would shock you. Their only tools are a simple iron file, some connecting rods, strength and dexterity. These urban plumbers unclog the pipes and drain off the waste, thus delivering Marrakech from certain sickening odours. A small but indispensable trade!
