Hood River City Councilors received a report on a proposed system of charges and surcharges to incentivize industries that produced a large amount of wastewater to pre-treat it before it reaches the municipal treatment plant.  Consultant Wayne Heniemann says the goal is to recover the cost of high-strength wastewater treatment and prevent costs from being passed on to other ratepayers.  The proposed plan would call for users whose highest day of outflow is less than 65 percent of limits would receive a 10 percent discount…while those above 90 percent would see charges increased from the base by ten percent…and there would be automatic fines for exceeding limits but with opportunities for users to make operational changes before being fined.  Heinemann says the City currently has four system users that would be impacted by this plan.  City Council will consider the proposal at a future meeting.
