We have a double W word today for ABC Wednesday: wastewater!
Since the public gardens in the Negev town of Omer are irrigated with effluents (wastewater), drinking from the town garden taps or hoses is . . . is what?! -- "frohibited"!
Haha, another Israeli sign blooper!
Purple is the conventional color to warn of effluents.
I have seen big purple valves in fields but this was my first time to see all the drip irrigation hoses thus marked.
The funny signs and the purple pipes are all along this long hedge, and behind the fence are several kindergartens.
Maybe that's why they are being so careful to warn about the water.
