Whanganui's new wastewater treatment plant proved a surprise hit when an open day was held at the Airport Road facility last Sunday.
Bright and shiny, it attracted hundreds of sightseers, perhaps keen to check out where their rates were going.
Council could have cashed in on its curiosity value by selling tickets but that would have smacked of double dipping, and once up and running the city's latest tourist attraction will have a somewhat less appealing aroma.
Still, the new plant got a positive reaction, and council will be hoping that goodwill extends to the bill to cover its more than $40 million price tag.
That bill will come in the form of a rates demand which this year is set to rise by an average of 4.5 per cent, prior to public consultation. The wastewater treatment plant is responsible for a chunk of that increase.
