The new rates would increase monthly fees for single-family homes by 70 cents to $23.93, according to an analysis by city staff. The City Council is scheduled to hear a third and final reading of the proposal Tuesday.
In addition to slightly higher residential rates, the city is proposing a onetime $12 fee for new accounts and increased fees for dumping sewage.
If the City Council approves the measure Tuesday, the new fee structure will go into effect Jan. 1.
City staff predicted the fee increases will generate more than $500,000 to the city's yearly budget. That money would help fund upgrades to Boise's sewer treatment plants as the city works toward reducing the amount of phosphorous in the treated wastewater the plants release, spokesman Vince Trimboli said.
