More likely councillor types who wouldn't know the Bernoulli effect if it strolled up and kicked them in the arse, but the end result for taxpayers is the same...
Or maybe people who work in the water industry see water sucked back when there are burst water mains (due presumably to the Bernouille effect) and thus take precautions to minimise the chance of sucking back contaminated water.
Taxpayers? It is the businesses that have to pay for taking these precautions on their own premises.
