A new Oregon City fee is a hidden tax on clean water  

UPDATE July 8, 2015

On Monday, July 6, a Circuit Court Judge rejected legal claims filed by the Tri-City Service District challenging the legality of a fee imposed by Oregon City on businesses or utilities operating within city-owned rights-of-way. The fee imposed in October 2013 sought to assess the district nearly $200,000 last year, with the amount increasing annually. The district challenged the fee as excessive, believing that it presents an unnecessary expense for ratepayers.

No decision has been made on whether to appeal the ruling. The district and its municipal partners are considering all legal options and the implications of the ruling on district customers.

Wipes can ‘wipe out’ costly sewer systems - Wet wipes, baby wipes, cleansing wipes, disinfecting wipes, surface wipes, hand wipes, antibacterial wipes, bathroom wipes or disposable moist towelettes. Whatever you call them, no matter what the packaging says, DO NOT FLUSH! The packaging might say they’re flushable, but wipes, no matter the cleaning purpose, are causing expensive problems for sewer operators all over the world and should be disposed of in a waste receptacle and sent to a landfill to decompose. To find out what happens after you flush, please watch the video Down the Drain.
