Portland homeowners could face about a $4.50 monthly increase in their water and sewer bills in July, under 2014-15 budgets proposed by City Commissioner Nick Fish.

Fish, who oversees the Water Bureau and Bureau of Environmental Services, asked both agencies to cut some existing programs so they could keep the combined sewer and water rate hike for 2014-15 under 5 percent. Fish's recommendations, which amount to a combined increase of about 4.9 percent, were forwarded recently to Mayor Charlie Hales, who will take them into account when he submits his recommended city budget in coming weeks.
