Daytime protests weren’t enough to stop the Poway City Council from approving a set of rate hikes on water and sewer services in the city. The proposal, which passed unanimously, calls for a 4.5-percent increase on the water commodity use rate, a 7.5-percent hike on the fixed water meter charge, and 3.25 percent increases on the sewer commodity rate and the sewer service charge. “What goes up never comes down in terms of taxes, or water,” Poway resident Jason Chynn said. “They just go up, up, up, and never come back down.”
