In a former life, I sold vibration equipment for casting concrete. I was bemused by the number of companies making fibrous concrete septic tanks in Ireland (dozens of the buggers) and the number in England, (one, and sold as part of an agricultural package to customers, mainly in Ireland.)

By my reckoning, such an inspector job would be the most secure public sector job in The Republic. Even some suburbs have resisted mains sewerage as the tank fashion was, at any rate when I was involved, in the '80s, big business.

Oh, and every farm you went to in a morning; huge fry up. Every farm you went to in an afternoon; huge plate of stew. Four or five calls a day? Ah.. That's why they have so many septic tanks.....
